+TypeScriptはJavaScriptを拡張して作られたプログラミング言語です。トレンドが示すとおり、TypeScriptはJavaScriptに代わって第一に選択される言語になりました。TypeScriptが提供する静的型システムは、コードの保守性と可読性を大幅に向上させます。またブラウザ等の互換性を心配することなく、モダンで便利なJavaScriptの機能を利用できます。 + +[TypeScript DeepDive](https://github.com/basarat/typescript-book/)は初心者からベテランまで役立つオープンソースのドキュメントです。JavaScriptのモダンな機能からTypeScriptの様々な魔法に至るまで丁寧に説明されています。多くのコードサンプルがあり、具体的なTypeScriptの使い方を簡単に理解できます。TypeScript

Create React Appを利用する場合 + +TypeScriptを使用してReactのWebアプリケーションを作成する場合、最も一般的な方法は、[Create React App](https://github.com/facebook/create-react-app)を使うことです。このツールはReactの開発チームがメンテナンスを行っているツールです。公式にTypeScriptのテンプレートが提供されています。 + +### 簡単にプロジェクトをセットアップする + +[Reactの公式Webサイト](https://reactjs.org/docs/static-type-checking.html#using-typescript-with-create-react-app)に書かれているように`npx create-react-app my-app --template typescript`というコマンドを実行します。`my-app`の部分には、プロジェクトに利用するフォルダ名を指定します。これで、最初からTypeScriptを利用可能なプロジェクトを簡単に作成できます。 + +```text +npx create-react-app my-app --template typescript +cd my-app +npm start # または、yarn start +``` + +これで、開発用サーバが起動し、 [http://localhost:3000/](http://localhost:3000/) にアクセスして動作を確認しながら、開発を進めることができます。この開発用サーバーは、ファイルの更新を監視しているので、TypeScriptのコードを変更すれば、自動的にコンパイルされ、ブラウザがリロードされます。この仕組みをLive Reloadや、Hot Reloadと呼びます。 + +### プロジェクトの詳細設定 + +Create React Appでプロジェクトを作成すると、下記のような`tsconfig.json`が作成されます。これを必要に応じて修正し、TypeScriptのコンパイラの動作を、好みに合わせて調整することができます。 + +```javascript +{ + "compilerOptions": { + "target": "es5", + "lib": [ + "dom", + "dom.iterable", + "esnext" + ], + "allowJs": true, + "skipLibCheck": true, + "esModuleInterop": true, + "allowSyntheticDefaultImports": true, + "strict": true, + "forceConsistentCasingInFileNames": true, + "module": "esnext", + "moduleResolution": "node", + "resolveJsonModule": true, + "isolatedModules": true, + "noEmit": true, + "jsx": "react" + }, + "include": [ + "src" + ] +} +``` + +## プロジェクトのビルド + +`npm run build` または `yarn build` のコマンドで、本番環境用のビルドを実行できます。これで、Reactチームによって本番環境に最適化されたバンドルファイルを出力できます。 diff --git a/code/async-await/es5/asyncAwaitES5.js b/code/async-await/es5/asyncAwaitES5.js new file mode 100644 index 000000000..4d574457a --- /dev/null +++ b/code/async-await/es5/asyncAwaitES5.js @@ -0,0 +1,70 @@ +var __awaiter = (this && this.__awaiter) || function (thisArg, _arguments, P, generator) { + return new (P || (P = Promise))(function (resolve, reject) { + function fulfilled(value) { try { step(generator.next(value)); } catch (e) { reject(e); } } + function rejected(value) { try { step(generator["throw"](value)); } catch (e) { reject(e); } } + function step(result) { result.done ? resolve(result.value) : new P(function (resolve) { resolve(result.value); }).then(fulfilled, rejected); } + step((generator = generator.apply(thisArg, _arguments || [])).next()); + }); +}; +var __generator = (this && this.__generator) || function (thisArg, body) { + var _ = { label: 0, sent: function() { if (t[0] & 1) throw t[1]; return t[1]; }, trys: [], ops: [] }, f, y, t, g; + return g = { next: verb(0), "throw": verb(1), "return": verb(2) }, typeof Symbol === "function" && (g[Symbol.iterator] = function() { return this; }), g; + function verb(n) { return function (v) { return step([n, v]); }; } + function step(op) { + if (f) throw new TypeError("Generator is already executing."); + while (_) try { + if (f = 1, y && (t = y[op[0] & 2 ?

+``` +`this`はJavaScriptにおいて昔から頭痛の種でした。 +ある賢い人はかつて「私は`this`の意味をすぐに忘れるJavaScriptが嫌いだ」と言いました。アロー関数は、それを囲んだコンテキストから`this`を捕捉します。純粋なJavaScriptだけで書かれたクラスを使って考えてみましょう: + +```ts +function Person(age) { + this.age = age; + this.growOld = function() { + this.age++; + } +} +var person = new Person(1); +setTimeout(person.growOld,1000); + +setTimeout(function() { console.log(person.age); },2000); // 1, should have been 2 +``` +このコードをブラウザで実行すると、関数内の`this`は`window`を指します。なぜなら、`window`が`growOld`関数を実行しているからです。修正方法は、アロー関数を使うことです: +```ts +function Person(age) { + this.age = age; + this.growOld = () => { + this.age++; + } +} +var person = new Person(1); +setTimeout(person.growOld,1000); + +setTimeout(function() { console.log(person.age); },2000); // 2 +``` +これがうまくいく理由は、アロー関数が、関数本体の外側の`this`を捕捉するからです。次のJavaScriptコードは同等の動きをします(TypeScriptを使用しない場合の書き方です)。 +```ts +function Person(age) { + this.age = age; + var _this = this; // capture this + this.growOld = function() { + _this.age++; // use the captured this + } +} +var person = new Person(1); +setTimeout(person.growOld,1000); + +setTimeout(function() { console.log(person.age); },2000); // 2 +``` +TypeScriptを使っているので、はるかに快適な構文で書けます。アロー関数とクラスは、組み合わせることができます: +```ts +class Person { + constructor(public age:number) {} + growOld = () => { + this.age++; + } +} +var person = new Person(1); +setTimeout(person.growOld,1000); + +setTimeout(function() { console.log(person.age); },2000); // 2 +``` + +> [このパターンについてのSweetなビデオ🌹](https://egghead.io/lessons/typescript-make-usages-of-this-safe-in-class-methods) + +#### Tip:アロー関数の必要性 +簡潔な構文が得られることに加えて、関数を他の何かに呼び出してもらいたい場合も、アロー関数を使うだけで良いのです。本質的には以下の通りです: +```ts +var growOld = person.growOld; +// Then later someone else calls it: +growOld(); +``` +自分で呼び出す場合は以下のようになります: +```ts +person.growOld(); +``` +どちらでも、`this`は正しいコンテキストになります(この例では`person`)。 + +#### Tip:アロー関数の危険性 + +実は、`this`を*呼び出しコンテキストにしたい*場合は*アロー関数を使うべきではありません*。jquery、underscore、mochaのようなライブラリで使用するコールバックのケースです。ドキュメントが`this`の機能について言及している場合は、おそらくアロー関数の代わりに`function`を使うべきでしょう。同様に、あなたが`arguments`を使うことを予定している場合は、アロー関数を使用しないでください。 + +#### Tip:`this`を使用するライブラリのアロー関数 +thisを使う多くのライブラリ、例えば`jQuery`の反復(例: )は`this`を使って現在反復中のオブジェクトを渡します。このようなケースにおいて、ライブラリが渡した`this`だけでなく周囲のコンテキストにもアクセスしたい場合は、アロー関数が無いときに行うように`_self`のような一時変数を使用してください。 + +```ts +let _self = this; +something.each(function() { + console.log(_self); // the lexically scoped value + console.log(this); // the library passed value +}); +``` + +#### Tip:アロー関数と継承 +クラスのプロパティとしてのアロー関数は、継承において正常に動作します: + +```ts +class Adder { + constructor(public a: number) {} + add = (b: number): number => { + return this.a + b;

+})(Point); +``` + +IIFEは、TypeScriptがベースクラス `Point`を`_super`変数に捕捉することを簡単にし、かつ、それがクラス本体で一貫して使用されていることに注意してください。 + +### `__extends` + +クラスを継承するとTypeScriptが次の関数を生成することに、すぐに気づくでしょう: + +```ts +var __extends = this.__extends || function (d, b) { + for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p]; + function __() { this.constructor = d; } + __.prototype = b.prototype; + d.prototype = new __(); +}; +``` +ここで `d`は派生クラスを指し、`b`はベースクラスを指します。この関数は次の2つのことを行います: + +1. 親クラスの静的メンバを子クラスにコピーする:`for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];` +1. 子クラス関数のプロトタイプを準備し、必要に応じて親の`proto`のメンバを検索できるようにする。つまり、実質的に `d.prototype.__proto__ = b.prototype` です。 + +1を理解するのに苦労する人はほとんどいませんが、2については多くの人が理解に苦しみます。そのため、順番に説明します。 + +#### `d.prototype.__proto__ = b.prototype` + +これについて多くの人を教えた結果、次のような説明が最もシンプルだと分かりました。まず、`__extends`のコードが、単純な`d.prototype.__proto__ = b.prototype`とどうして同じなのか、そしてなぜ、この行それ自体が重要であるのかを説明します。これをすべて理解するためには、これらのことを理解する必要があります: + +1. `__proto__` +1. `prototype` +1. `new`の関数の内側の`this`に対する効果 +1. `new`の`prototype`と`__proto__`に対する効果 + +JavaScriptのすべてのオブジェクトは `__proto__`メンバを含んでいます。このメンバは古いブラウザではアクセスできないことがよくあります(ドキュメントでは、この魔法のプロパティを `[[prototype]]`と呼ぶことがあります)。それは1つの目的を持っています:検索しているプロパティがオブジェクトに見つからない場合(例えば `obj.property`)、`obj.__proto__.property`を検索します。それでもまだ見つからなければ、 `obj.__proto__.__proto__.property`を検索します: それが見つかるか、最後の`.__proto__`自体が`null`となるまで続きます。これは、JavaScriptが*プロトタイプ継承*(prototypal inheritance)をサポートしていることを説明しています。次の例でこれを示します。chromeコンソールまたはNode.jsで実行することが可能です。 + +```ts +var foo = {} + +// setup on foo as well as foo.__proto__ +foo.bar = 123; +foo.__proto__.bar = 456; + +console.log(foo.bar); // 123 +delete foo.bar; // remove from object +console.log(foo.bar); // 456 +delete foo.__proto__.bar; // remove from foo.__proto__ +console.log(foo.bar); // undefined +``` + +これで、あなたは `__proto__`を理解できました。もう1つの便利な事実は、JavaScriptの関数(`function`)には`prototype`というプロパティがあり、そして、その`constructor`メンバは、逆に関数を指しているということです。これを以下に示します: + +```ts +function Foo() { } +console.log(Foo.prototype); // {} i.e. it exists and is not undefined +console.log(Foo.prototype.constructor === Foo); // Has a member called `constructor` pointing back to the function +``` + +次に、呼び出された関数内の`this`に`new`が及ぼす影響を見てみましょう。基本的に、`new`を使って呼び出された関数の内側の`this`は、関数から返される新しく生成されたオブジェクトを指します。関数内で`this`のプロパティを変更するのは簡単です: + +```ts +function Foo() { + this.bar = 123; +} + +// call with the new operator +var newFoo = new Foo(); +console.log(newFoo.bar); // 123 +``` +ここであなたが知る必要があることは、関数に対する`new`の呼び出しにより、関数の`prototype`が、生成されたオブジェクトの`__proto__`に設定されることです。次のコードを実行することによって、それを完全に理解できます: + +```ts +function Foo() { } + +var foo = new Foo(); + +console.log(foo.__proto__ === Foo.prototype); // True! +``` + +それだけのことです。今度は`__extends`の抜粋を見てください。これらの行に番号を振りました: + +```ts +1 function __() { this.constructor = d; } +2 __.prototype = b.prototype; +3 d.prototype = new __(); +``` + +この関数を逆から見ると、3行目の`d.prototype = new __()`は、 `d.prototype = {__proto__ : __.prototype}`を意味します(`prototype`と`__proto__`に対する`new`の効果によるものです)。それを2行目(`__.prototype = b.prototype;`)と組み合わせると、`d.prototype = {__proto__ : b.prototype}`となります。 + +しかし、待ってください。私達は、単に`d.prototype.__proto__`が変更され、`d.prototype.constructor`は、それまで通り維持されることを望んでいました。そこで重要な意味があるのが、最初の行(`function __() { this.constructor = d; }`)です。これは`d.prototype = {__proto__ : __.prototype, constructor : d}`を実現できます(これは関数の内側の`this`に対する`new`による効果のためです)。したがって`d.prototype.constructor`を復元しているので、我々が変更したものは、`__proto__`たった1つだけであり、それゆえ`d.prototype.__proto__ = b.prototype`となります。 + +#### `d.prototype.__proto__ = b.prototype`の意味 + +これを行うことによって、子クラスにメンバ関数を追加しつつ、その他のメンバは基本クラスから継承することができます。次の簡単な例で説明します: + +```ts +function Animal() { } +Animal.prototype.walk = function () { console.log('walk') }; + +function Bird() { } +Bird.prototype.__proto__ = Animal.prototype; +Bird.prototype.fly = function () { console.log('fly') }; + +var bird = new Bird(); +bird.walk(); +bird.fly(); +``` +基本的に`bird.fly`は`bird.__proto__.fly`(`new`は`bird.__proto__`が`Bird.prototype`を指すようにすることを思い出してください)から検索され、`bird.walk`(継承されたメンバ)は`bird.__proto__.__proto__.walk`から検索されます(`bird.__proto__ == Bird.prototype`、そして、`bird.__proto__.__proto__` == `Animal.prototype`です)。 diff --git a/docs/classes.md b/docs/classes.md new file mode 100644 index 000000000..fe313d9c4 --- /dev/null +++ b/docs/classes.md @@ -0,0 +1,164 @@ +### クラス(Classes) +JavaScriptにおいて、クラスを第一級のもの(first class item)として持つことが重要な理由は次の通りです: + +1.

+``` +これは`{`が新しい**変数スコープ**(variable scope)を作成しないためです。 変数`foo`はifブロックの内側にあっても外側にあっても同じです。これは、JavaScriptのプログラミングにおける一般的なエラーの原因です。そのため、TypeScript(とES6)は`let`キーワードを導入して真のブロックスコープ(block scoped)の変数を定義できるようにしています。つまり、`var`の代わりに`let`を使うと、スコープの外側で定義されているかもしれない変数とは異なる、真にユニークな変数を得ることができます。先ほどと同じ例を`let`で示します: + +```ts +let foo = 123; +if (true) { + let foo = 456; +} +console.log(foo); //

0 +``` +間違いなく、可能なときはいつでも`let`を使うべきです。そのほうが新しい開発者や他の言語での開発者にとって直感的です。 + +#### 関数はスコープを新たに作成する +これまで述べてきた、JavaScriptの関数が新しい変数スコープを作成することを例で示します。次のコードについて、考えてみてください。 + +```ts +var foo = 123; +function test() { + var foo = 456; +} +test(); +console.log(foo); // 123 +``` +これは期待通りに動作します。これがなければ、JavaScriptでコードを書くのは至難でしょう。 + +#### 生成されたJS(Generated JS) +TypeScriptによって生成されたJSは、同じ名前の`let`変数が既に周囲のスコープに存在する場合は、単純に変数名を変更します。`let`変数の単純な名前変更です。例えば、次の例は単純に、`let`を`var`に置き換えるだけです。 + +```ts +if (true) { + let foo = 123; +} + +// becomes // + +if (true) { + var foo = 123; +} +``` +しかし、変数名が既に周囲のスコープによって捕捉されている場合、次のように新しい変数名が生成されます(`_foo`に注目)。 + +```ts +var foo = '123'; +if (true) { + let foo = 123; +} + +// becomes // + +var foo = '123'; +if (true) { + var _foo = 123; // Renamed +} +``` + +#### Switch +`case`文の本体(body)を`{}`で囲んで、異なる`case`文で変数名を安全に再利用することができます: + +```ts +switch (name) { + case 'x': { + let x = 5; + // ... + break; + } + case 'y': { + let x = 10; + // ... + break; + } +} +``` + +#### クロージャ内の`let` +一般的にJavaScriptのDeveloperに対して面接で質問されるのは、次のような単純なプログラムが、「何をログに表示するか?」です: + +```ts +var funcs = []; +// create a bunch of functions +for (var i = 0; i < 3; i++) { + funcs.push(function() { + console.log(i); + }) +} +// call them +for (var j = 0; j < 3; j++) { + funcs[j](); +} +``` + +ある人は`0,1,2`であると予測したでしょう。意外なことに、3つの関数はすべて「3」を表示します。理由は、3つの関数すべて外側のスコープの変数`i`を使用しており、それらを実行するときに(第2のループで)`i`の値が`3`だからです(これは最初のループの終了条件です)。 + +修正方法のひとつは、ループごとに、その反復(iteration)だけの変数スコープを新しく作ることです。既に学んだことですが、下記に示すように、新しい関数を作成し、ただちに実行することで新しい変数スコープを作成できます(IIFEパターンです `(function(){/ * body * /})();`)。 + +```ts +var funcs = []; +// create a bunch of functions +for (var i = 0; i < 3; i++) { + (function() { + var local = i; + funcs.push(function() { + console.log(local); + }) + })(); +} +// call them +for (var j = 0; j < 3; j++) { + funcs[j](); +} +``` +ここで関数は*local*変数(わかりやすく`local`と命名しました)を閉じ込めて(それゆえに`closure`と呼ばれます)、ループ変数`i`の代わりに使用します。 + +> クロージャはパフォーマンスに影響を与えます(周囲のスコープの状態を保存する必要があるためです)。 + +ループ内のES6の`let`キーワードは、前に示した例とまったく同じ振る舞いをします。 + +```ts +var funcs = []; +// create a bunch of functions +for (let i = 0; i < 3; i++) { // Note the use of let + funcs.push(function() { + console.log(i); + }) +} +// call them +for (var j = 0; j < 3; j++) { + funcs[j](); +} +``` + +`var`の代わりに`let`を使うと、各ループ反復(iteration)に固有の変数`i`が作られます。 + +#### 要約 +`let`は、コードの大部分で非常に役立ちます。コードの可読性を大幅に改善し、プログラミング誤りが発生する可能性を減らします。 + +

+ +export function loadFoo() { + // This is lazy loading `foo` and using the original module *only* as a type annotation + var _foo: typeof foo = require('foo'); + // Now use `_foo` as a variable instead of `foo`. +} +``` + +同様の`amd`(requirejsを使用)のサンプルは次のようになります: +```ts +import foo = require('foo'); + +export function loadFoo() { + // This is lazy loading `foo` and using the original module *only* as a type annotation + require(['foo'], (_foo: typeof foo) => { + // Now use `_foo` as a variable instead of `foo`. + }); +} +``` + +このパターンは一般的に使用されます。 +* Webアプリケーションにおいて、特定のルートの場合のみ特定のJavaScriptをロードする +* nodeアプリケーションにおいて、アプリケーションの起動を高速化したい場合に、特定のモジュールだけをロードする + +### ユースケース:循環依存を避ける + +遅延ロードの使用例と同様に、特定のモジュールローダ(commonjs/nodeと、amd/requirejs)は循環依存のため、うまく動作しません。そのような場合には、1つの方向に遅延ロードを行うようにし、反対方向のロードの前にロードしておくと便利です。 + +### ユースケース:確実にインポートする + +場合によっては、副作用(side effect)のためだけにファイルをロードすることもできます(例えば[CodeMirror addons](https://codemirror.net/doc/manual.html#addons)のように、モジュールを他のライブラリに登録させる場合など)。しかし、単に`import/require`を行うと、トランスパイルされたJavaScriptはモジュールへの依存関係を持たず、モジュールローダー(例えばwebpack)はインポートを完全に無視するかもしれません。このような場合、 `ensureImport`変数を使用して、コンパイルされたJavaScriptがモジュールに依存するようにすることができます。 + +```ts +import foo = require('./foo');

We explain the reasons below +function loadJSON(filename: string, cb: (error: Error, data: any) => void) { + fs.readFile(filename, function (err, data) { + if (err) cb(err); + else cb(null, JSON.parse(data)); + }); +} +``` + +十分シンプルです。コールバックをとり、ファイルシステムのエラーをコールバックに渡します。ファイルシステムのエラーがなければ、`JSON.parse`の結果を返します。コールバックに基づいて非同期関数を利用するときに注意すべき点は次のとおりです。 + +1. 決してコールバックを2回呼ばないでください。 +1. 決して Error を投げないでください。 + +しかしながら、この単純な関数は2つ目の点に対応できません。実際にJSON.parseに間違ったJSONが渡されると、Error が発生し、コールバックが呼び出されず、アプリケーションがクラッシュします。これを以下の例で示します: + +```ts +import fs = require('fs'); + +// A decent initial attempt .... but not correct +function loadJSON(filename: string, cb: (error: Error, data: any) => void) { + fs.readFile(filename, function (err, data) { + if (err) cb(err); + else cb(null, JSON.parse(data)); + }); +} + +// load invalid json +loadJSON('invalid.json', function (err, data) { + // This code never executes + if (err) console.log('bad.json error', err.message); + else console.log(data); +}); +``` + +これを修正するための素朴な試みは、次の例に示すように`JSON.parse`をtry catchにラップすることです。 + +```ts +import fs = require('fs'); + +// A better attempt ... but still not correct +function loadJSON(filename: string, cb: (error: Error) => void) { + fs.readFile(filename, function (err, data) { + if (err) { + cb(err); + } + else { + try { + cb(null, JSON.parse(data));

+}); +``` + +しかし、このコードには些細なバグがあります。もしコールバック(`cb`)がコールされ、`JSON.parse`がコールされず、エラーをスローした場合、`try`/`catch`でラップしているため、`catch`が実行され、コールバックを再度コールされてしまいます。つまり、コールバックが二度コールされてしまいます!これを以下の例で示します: + +```ts +import fs = require('fs'); + +function loadJSON(filename: string, cb: (error: Error) => void) { + fs.readFile(filename, function (err, data) { + if (err) { + cb(err); + } + else { + try { + cb(null, JSON.parse(data)); + } + catch (err) { + cb(err);

+ else { + // let's simulate an error by trying to access a property on an undefined variable + var foo; + // The following code throws `Error: Cannot read property 'bar' of undefined` + console.log(foo.bar); + } +}); +``` + +```bash +$ node asyncbadcatchdemo.js +our callback called +our callback called +Error: Cannot read property 'bar' of undefined +``` + +これは、`loadJSON`関数が間違って`try`ブロックでコールバックをラップしたためです。ここで覚えておくべき簡単な教訓があります。 + +> シンプルな教訓:コールバックをコールするとき以外のすべての同期コードをtry catchに含めること。 + +このシンプルな教訓に基づいて、我々は完全に機能する非同期バージョンの`loadJSON`を作成できます: + +```ts +import fs = require('fs'); + +function loadJSON(filename: string, cb: (error: Error) => void) { + fs.readFile(filename, function (err, data) { + if (err) return cb(err); + // Contain all your sync code in a try catch + try { + var parsed = JSON.parse(data); + } + catch (err) { + return cb(err); + } + // except when you call the callback + return cb(null, parsed); + }); +} +``` +確かに何回か行えば、そう難しいことではありませんが、単に、良いエラー処理を書くためだけに多くの定型的なコードが必要です。では、Promiseを使ってJavaScriptの非同期処理に取り組むための、より良い方法を見てみましょう。 + +## Promiseを作る + +Promiseの状態は、`pending`(保留中)または`fulfilled`(履行済み)または`rejected`(拒絶済み)のいずれかになります。 + +![Promiseの宣言と運命](https://raw.githubusercontent.com/basarat/typescript-book/master/images/promise%20states%20and%20fates.png) + +Promiseの作り方を見てみましょう。Promise(Promiseのコンストラクタ)に対して`new`を呼び出すだけです。Promiseのコンストラクタには、Promiseの状態を決めるための`resolve`関数と`reject`関数が渡されます。 + +```ts +const promise = new Promise((resolve, reject) => { + // the resolve / reject functions control the fate of the promise +});

+ }) + .catch((err) => { + console.log('second catch: ' + err.message); // never called + }) +``` + +* `catch`はチェーンの前部分でエラーが発生した場合にのみコールされます: + +```ts +Promise.resolve(123) + .then((res) => { + return 456; + }) + .catch((err) => { + console.log("HERE"); // never called + }) +``` + +Promiseチェーンに関する事実: + +* エラーが起きた場合、後続の`catch`にジャンプします(そして途中の`then`はスキップします) +* 同期処理のエラーについても同様に、最も近い後続の`catch`で捕捉されます + +Promiseは、生のコールバックに比べて優れたエラー処理を可能にする非同期プログラミングのパラダイムを我々に提供してくれます。さらに下記に詳しく記載します。 + + +### TypeScriptとPromise +TypeScriptが素晴らしい点は、それがPromiseチェーンを通じて流れる値を理解してくれることです。 + +```ts +Promise.resolve(123) + .then((res) => { + // res is inferred to be of type `number` + return true; + }) + .then((res) => { + // res is inferred to be of type `boolean` + + }); +``` + +もちろん、Promiseを返す可能性のある関数呼び出しも理解してくれます。 + +```ts +function iReturnPromiseAfter1Second(): Promise { + return new Promise((resolve) => { + setTimeout(() => resolve("Hello world!"), 1000); + }); +} + +Promise.resolve(123) + .then((res) => { + // res is inferred to be of type `number` + return iReturnPromiseAfter1Second(); // We are returning `Promise` + }) + .then((res) => { + // res is inferred to be of type `string` + console.log(res); // Hello world! + }); +``` + + +### コールバックスタイルの関数をPromiseを返すように変える + +関数呼び出しをPromiseにラップして +- エラーが発生した場合は `reject`をコールする +- すべてうまく行った場合は`resolve`をコールする + +例えば`fs.readFile`をラップしましょう: + +```ts +import fs = require('fs'); +function readFileAsync(filename: string): Promise { + return new Promise((resolve,reject) => { + fs.readFile(filename,(err,result) => { + if (err) reject(err); + else resolve(result); + }); + }); +} +``` + + +### JSONの例を見直す + +次に、`loadJSON`の例を見直して、Promiseを使う非同期バージョンを書いてみましょう。やるべきことは、Promiseとしてファイル内容を読み、JSONとしてパースする、それだけです。これを以下の例で示します: + +```ts +function loadJSONAsync(filename: string): Promise { + return readFileAsync(filename) // Use the function we just wrote + .then(function (res) { + return JSON.parse(res); + }); +} +``` + +使い方(このセクションの始めに紹介した同期( `sync` )バージョンとどれだけ似ているかに注目してください🌹): +```ts +// good json file +loadJSONAsync('good.json') + .then(function (val) { console.log(val); }) + .catch(function (err) { + console.log('good.json error', err.message); // never called + }) + +// non-existent json file + .then(function () { + return loadJSONAsync('absent.json'); + }) + .then(function (val) { console.log(val); }) // never called + .catch(function (err) { + console.log('absent.json error', err.message); + }) + +// invalid json file + .then(function () { + return loadJSONAsync('invalid.json'); + }) + .then(function (val) { console.log(val); }) // never called + .catch(function (err) { + console.log('bad.json error', err.message); + }); +``` + +この関数がよりシンプルになった理由は、"`loadFile`(async)+`JSON.parse`(sync)=>`catch`"の連結をPromiseチェーンによって行ったためです。また、コールバックは我々ではなくPromiseチェーンによってコールされるので、コールバックを`try/catch`でラップしてしまう誤りが起きる可能性はありませんでした。 + +### 並列制御フロー(Parallel control flow) +私たちは、Promiseを使って非同期タスクの順次処理(シーケンシャル処理)を行うことがいかに簡単かを見てきました。単に`then`の呼び出しをチェーンするだけなのです。 + +しかし、複数の非同期処理を実行し、すべてのタスクが終わったタイミングで何らかの処理を行いたいケースがあるかもしれません。`Promise`は静的な`Promise.all`関数を提供します。この関数は、`n`個のPromiseがすべて完了するまで待つことができます。`n`個のPromiseの配列を渡すと、`n`個の解決された値の配列を返します。以下では、チェーンの例と合わせて並列で処理する例を示します。 + +```ts +// an async function to simulate loading an item from some server +function loadItem(id: number): Promise<{ id: number }> { + return new Promise((resolve) => { + console.log('loading item', id); + setTimeout(() => { // simulate a server delay + resolve({ id: id }); + }, 1000); + }); +} + +// Chaining +let item1, item2; +loadItem(1) + .then((res) => { + item1 = res; + return loadItem(2); + }) + .then((res) => { + item2 = res; + console.log('done'); + }); // overall time will be around 2s + +// Parallel +Promise.all([loadItem(1), loadItem(2)]) + .then((res) => { + [item1, item2] = res; + console.log('done'); + }); // overall time will be around 1s +``` + +ある場合には、複数の非同期タスクを実行するが、これらのタスクの内1つだけが完了すれば良いケースもあるでしょう。`Promise`は、このユースケースに対して`Promise.race`というStatic関数を提供しています: + +```ts +var task1 = new Promise(function(resolve, reject) { + setTimeout(resolve, 1000, 'one'); +}); +var task2 = new Promise(function(resolve, reject) { + setTimeout(resolve, 2000, 'two'); +}); + +Promise.race([task1, task2]).then(function(value) { + console.log(value); // "one" + // Both resolve, but task1 resolves faster +}); +``` + +### コールバック関数をPromiseに変換する + +これを行うために信頼性が高い方法は、自分でコードを書くことです。例えば`setTimeout`をPromiseを使った`delay`関数に変換するのは非常に簡単です: + +```ts +const delay = (ms: number) => new Promise(res => setTimeout(res, ms)); +``` + +NodeJSにはこれを行う便利で使いやすい関数があることを知っておいてください。これは `Nodeスタイルの関数 => Promiseを返す関数` に変える魔法を行ってくれます。 + +```ts +/** Sample usage */ +import fs = require('fs'); +import util = require('util'); +const readFile = util.promisify(fs.readFile);

+ expect($div[0].className).to.contain('heading'); + }) +// これは単なる例です。普通は`.should('have.class', 'heading')`のように書きます。 +``` + +> ヒント: cypressにはcallbackの呼び出しにも自動リトライ機能があるため、普通の文字列のチェーンと同じように壊れにくいコードを書くことができます。 + +## ヒント: コマンドとチェーン +cypressチェーン内のすべての関数呼び出しは`command`です。`should`コマンドはアサーションです。チェーンとアクションの別々の*カテゴリ*を別々に開始することは慣習になっています: + +```ts +// Don't do this +cy.get(/**something*/) + .should(/**something*/) + .click() + .should(/**something*/) + .get(/**something else*/) + .should(/**something*/) + +// Prefer separating the two gets +cy.get(/**something*/) + .should(/**something*/) + .click() + .should(/**something*/) + +cy.get(/**something else*/) + .should(/**something*/) +``` + +他の何かのライブラリは、同時にこのコードを評価し、実行します。それらのライブラリは、単一のチェーンが必要になります。それはセレクタやアサーションが混在してデバッグを行うのが難しくなります。 + +Cypressのコマンドは、本質的に、コマンドを後で実行するためのCypressランタイムへの*宣言*です。端的な言葉:Cypressはより簡単にします + +## ヒント: より容易なクエリのために`contains`を使う + +下記に例を示します: +```ts +cy.get('#foo') + // Once #foo is found the following: + .contains('Submit') + .click() + // ^ will continue to search for something that has text `Submit` and fail if it times out. + // ^ After it is found trigger a click on the HTML Node that contained the text `Submit`. +``` + +## ヒント: スマートディレイとリトライ +Cypressはたくさんの非同期のものに対して、自動的に待ち(そしてリトライし)ます。 +``` +// If there is no request against the `foo` alias cypress will wait for 4 seconds automatically +cy.wait('@foo') +// If there is no element with id #foo cypress will wait for 4 seconds automatically and keep retrying +cy.get('#foo') +``` +これにより、テストコードフローに常に任意のタイムアウトのロジックを追加する必要がなくなります。 + +## ヒント: 暗黙のアサーション +Cypressには暗黙のアサーションという概念があります。1つ前のコマンドが原因でそれ移行のコマンドでエラーが発生したときに実行されます。These kick in if a future command is erroring because of a previous command. E.g. the following will error at `contains` (after automatic retries of course) as nothing found can get `click`ed: + +```ts +cy.get('#foo') + // Once #foo is found the following: + .contains('Submit') + .click() + // ^ Error: #foo does not have anything that `contains` `'Submit'` +``` + +伝統的なフレームワークでは、`null`には`click`がないというような恐ろしいエラーを目にすることでしょう。Cypressの場合、`#foo`には`Submit`が含まれていないという親切なエラーが表示されます。このようなエラーは暗黙のアサーションの一種です。 + +## ヒント: HTTPリクエストを待つ +アプリケーションが作るXHRに必要なすべてのタイムアウトが原因となり、多くのテストが脆くなりました。`cy.server`は次のことを簡単にします。 +* バックエンド呼び出しのエイリアスを作成する +* それらが発生するのを待つ + +例: + +```ts +cy.server() + .route('POST', 'https://example.com/api/application/load') + .as('load') // create an alias + +// Start test +cy.visit('/') + +// wait for the call +cy.wait('@load') + +// Now the data is loaded +``` + +## ヒント: HTTPリクエストのレスポンスをモックする +`route`を使ってリクエストのレスポンスを簡単にモックすることもできます: + +```ts +cy.server() + .route('POST', 'https://example.com/api/application/load', /* Example payload response */{success:true}); +``` + +### ヒント: HTTPリクエストのレスポンスをアサートする +リクエストのアサートは、モックを作らなくても`route`や`onRequest`/`onResponse`を使うことで実現できます。 + +```ts +cy.route({ + method: 'POST', + url: 'https://example.com/api/application/load', + onRequest: (xhr) => { + // Example assertion + expect(xhr.request.body.data).to.deep.equal({success:true}); + } +}) +``` + +## ヒント: 時間をモックする +`wait`を使ってある時間テストを一時停止することができます。自動的に"あなたはログアウトされます"という通知画面をテストする例: + +```ts +cy.visit('/'); +cy.wait(waitMilliseconds); +cy.get('#logoutNotification').should('be.visible'); +``` + +しかし、`cy.clock`と時間をモックし、`cy.tcl`を使用して時間を前倒しすることが推奨されます: + +```ts +cy.clock(); + +cy.visit('/'); +cy.tick(waitMilliseconds); +cy.get('#logoutNotification').should('be.visible'); +``` + +## ヒント: アプリケーションコードのユニットテスト +あなたはCypressを使ってアプリケーションコードを分離してユニットテストを行うことも可能です。 + +```ts +import { once } from '../../../src/app/utils'; + +// Later +it('should only call function once', () => { + let called = 0; + const callMe = once(()=>called++); + callMe(); + callMe(); + expect(called).to.equal(1); +}); +``` + +## ヒント: ユニットテストにおけるモック +もしあなたがアプリケーショのモジュールをユニットテストしていたら、あなたは`cy.stub`を使ってモックを提供することが可能です。例えば、あなたは`navigate`が関数`foo`で呼ばれることを確認できます: + +* `foo.ts` + +```ts +import { navigate } from 'takeme'; + +export function foo() { + navigate('/foo'); +} +``` + +* 下記を`some.spec.ts`で行います + +```ts +/// + +import { foo } from '../../../src/app/foo'; +import * as takeme from 'takeme'; + +describe('should work', () => { + it('should stub it', () => { + cy.stub(takeme, 'navigate');

})`)や、ネットワーク呼び出し(`cy.request('https://someurl').then((res /* network response */) => { debugger });`)すら可能です。しかし、慣用的な方法は、`cy.get('#foo').debug()`です。そして、テストランナーが`debug`で止まったときに、`get`をコマンドログでクリックすると自動的に`console.log`にあなたが知りたい`.get('#foo')`に関する情報が出力されます(そして、デバッグに必要な他のコマンドでも似たようなものです) + +## ヒント: サーバーを開始してテストを実行する +もしテストの前にローカルサーバーを起動したい場合は`start-server-and-test` [https://github.com/bahmutov/start-server-and-test](https://github.com/bahmutov/start-server-and-test) を依存関係に追加できます。それは次の引数を受け取ります。 +* サーバーを実行するためのnpmスクリプト +* サーバーが起動しているかをチェックするためのエンドポイント +* テストを初期化するためのnpmスクリプト + +package.jsonの例: +```json +{ + "scripts": { + "start-server": "npm start", + "run-tests": "mocha e2e-spec.js", + "ci": "start-server-and-test start-server http://localhost:8080 run-tests" + } +} +``` + +## リソース +* ウェブサイト:https://www.cypress.io/ +* あなたの最初のCypressテストを書く(Cypress IDEの素晴らしいツアー):https://docs.cypress.io/guides/getting-started/writing-your-first-test.html +* CI環境を設定する(例えば、そのまま`cypress run`で動く提供されたdockerイメージ):https://docs.cypress.io/guides/guides/continuous-integration.html +* レシピ(説明付きのレシピの一覧です。レシピのソースコードに移動するには見出しをクリックしてください): https://docs.cypress.io/examples/examples/recipes.html +* Visual Testing: https://docs.cypress.io/guides/tooling/visual-testing.html +* Optionally set a `baseUrl` in cypress.json to [prevent an initial reload that happens after first `visit`.](https://github.com/cypress-io/cypress/issues/2542) +* Code coverage with cypress: [Webcast](https://www.youtube.com/watch?v=C8g5X4vCZJA) diff --git a/docs/testing/intro.md b/docs/testing/intro.md new file mode 100644 index 000000000..67f54ff0d --- /dev/null +++ b/docs/testing/intro.md @@ -0,0 +1,4 @@ +# テスト +TypeScriptは、任意のJavaScriptテストフレームワークで使用できます。最悪の場合には、単純な`TypeScript -> JavaScript`変換をいつでも実行でき、向こう見ずに行動することができます。 + +とは言っても、このセクションでは私達が大いに楽しんだオプションを見てください🌹 diff --git a/docs/testing/jest.md b/docs/testing/jest.md new file mode 100644 index 000000000..9a8042c38 --- /dev/null +++ b/docs/testing/jest.md @@ -0,0 +1,208 @@ +# TypeScriptでJestを使う + +> [Jest/TypeScriptに関するPro eggheadレッスン](https://egghead.io/lessons/typescript-getting-started-with-jest-using-typescript) + +パーフェクトなテストのソリューションはありません。とはいえ、jestは優れたTypeScriptサポートを提供する優れたユニットテストのオプションです。 + +> 注意:単純なノードのpackage.json setupで始めることを前提としています。また、すべてのTypeScriptファイルは`src`フォルダに置かれていなければなりません。このフォルダは、きれいなプロジェクト設定のために(Jestを使わなくても)常に推奨されます。 + +## ステップ1:インストール + +npmを使用して次をインストールします。 + +```shell +npm i jest @types/jest ts-jest typescript -D +``` + +説明: + +* `jest`フレームワーク(`jest`)をインストールします +* `jest`の型(`@types/jest`)をインストールします +* Jest用のTypeScriptプリプロセッサ(`ts-jest`)をインストールします。これにより、Jestはその場でTypeScriptをトランスパイルすることができ、source-mapをサポートします +* `ts-jest` を使用するために必要なTypeScript コンパイラ(`typescript`)をインストールします +* これらのすべてを、あなたのdevの依存関係に保存してください(テストはほとんど常にnpmのdev-dependencyです) + +## ステップ2:Jestを設定する + +次の`jest.config.js`ファイルをプロジェクトのルートに追加します: + +```js +module.exports = { + "roots": [ + "/src" + ], + "testMatch": [ + "**/__tests__/**/*.+(ts|tsx|js)", + "**/?(*.)+(spec|test).+(ts|tsx|js)" + ], + "transform": { + "^.+\\.(ts|tsx)$": "ts-jest" + }, +} +``` + +説明: + +* *すべての*TypeScriptファイルをプロジェクトの`src`フォルダに入れることを常にお勧めします。これが前提とし、`roots`オプションを使用してこれを指定します。 +* `testMatch`設定は、ts/tsx/jsフォーマットで書かれた.test/.specファイルを発見するためのglobのパターンマッチャーです。 +* `transform`設定は、`jest`にts/tsxファイルに対して`ts-jest`を使うように指示します。 + +## 手順3:テストを実行する + +あなたのプロジェクトのルートから`npx jest`を実行すると、jestはあなたのテストを実行します。 + +### オプション:npmスクリプトのスクリプトターゲットを追加する + +`package.json`に追加してください: + +```json +{ + "test": "jest" +} +``` + +* これにより、簡単な`npm t`でテストを実行できます。 +* また、`npm t --watch`のwatchモードでも。 + +### オプション:watchモードでjestを実行する + +* `npx jest --watch` + +### 例 + +* `foo.ts`ファイルの場合: + +```js +export const sum + = (...a: number[]) => + a.reduce((acc, val) => acc + val, 0);

// Error: Supplied parameters do not match the signature of the call target +``` + +#### `Math`の例 +グローバル変数`Math`は`lib.d.ts`で定義されています(再度、あなたの開発ツールを使って定義に移動してください): + +```ts +/** An intrinsic object that provides basic mathematics functionality and constants. */ +declare var Math: Math; +``` + +すなわち、変数`Math`は`Math`インターフェースのインスタンスです。`Math`インターフェースは次のように定義されています: + +```ts +interface Math { + E: number; + LN10: number; + // others ... +} +``` + +つまり、グローバル変数の`Math`に物を追加したいのであれば、それをグローバルインターフェースの`Math`に追加するだけです。[`seedrandom`プロジェクト](https://www.npmjs.com/package/seedrandom) を参考に、グローバル`Math`オブジェクトに`seedrandom`関数を追加してください。これは非常に簡単に宣言できます: + +```ts +interface Math { + seedrandom(seed?: string); +} +``` + +そして、あなたはそれを使うことができます: + +```ts +Math.seedrandom(); +// or +Math.seedrandom("Any string you want!"); +``` + +#### `Date`の例 + +`lib.d.ts`の`Date`変数の定義を見ると、次のようになっています: + +```ts +declare var Date: DateConstructor; +``` +`DateConstructor`というインターフェースは、`Date`グローバル変数を使って使うことができるメンバが含まれている点で、`Math`と`Window`で見たものに似ています。 +例えば`Date.now()`です。これらのメンバに加えて、`Date`インスタンス(例えば`new Date()`)を作成するためのコンストラクタのシグネチャが含まれています。 `DateConstructor`インターフェースの断片を以下に示します: + +```ts +interface DateConstructor { + new (): Date; + // ... other construct signatures + + now(): number; + // ... other member functions +} +``` + +プロジェクト [`datejs`](https://github.com/abritinthebay/datejs) を考えてみましょう。 DateJSは、メンバを`Date`グローバル変数と`Date`インスタンスの両方に追加します。したがって、このライブラリのTypeScriptの定義は、以下のようになります(ところで、[コミュニティはすでにそれをあなたのために書いています](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/datejs/index.d)): + +```ts +/** DateJS Public Static Methods */ +interface DateConstructor { + /** Gets a date that is set to the current date.

+ // ... so on and so forth +} +``` +これにより、型安全な方法で次のようなことができます: + +```ts +var today = Date.today(); +var todayAfter1second = today.addMilliseconds(1000); +``` + +#### `string`の例 + +文字列の `lib.d.ts`を調べると、`Date`(`String`グローバル変数、`StringConstructor`インターフェース、`String`インターフェース)のようなものが見つかるでしょう。しかし、注意すべき点の1つは、以下のコードサンプルで示すように、`String`インターフェースは、文字列リテラルに対しても影響を与えます: + +```ts + +interface String { + endsWith(suffix: string): boolean; +} + +String.prototype.endsWith = function(suffix: string): boolean { + var str: string = this; + return str && str.indexOf(suffix, str.length - suffix.length) !== -1; +} + +console.log('foo bar'.endsWith('bas'));

+ for (let i = items.length - 1; i >= 0; i--) { + toreturn.push(items[i]); + } + return toreturn; +} + +var sample = [1, 2, 3]; +var reversed = reverse(sample); +console.log(reversed); // 3,2,1 + +// Safety! +reversed[0] = '1'; // Error! +reversed = ['1', '2']; // Error! + +reversed[0] = 1; // Okay +reversed = [1, 2]; // Okay +``` + +ここでは、`reverse`関数は何らかの型`T`の配列(`items: T[]`)を受け取り(`reverse`の型パラメータに注目)、`T`型の配列を返します(`: T[]`に注目)。 `reverse`関数は、同じ型の項目を返すので、`reversed`変数も`number[]`型であることがTypeScriptに分かるため、型の安全性が得られます。同様に`string[]`の配列を`reverse`関数に渡すと、返される結果も`string[]`の配列になり、以下に示すような型安全性が得られます: + +```ts +var strArr = ['1', '2']; +var reversedStrs = reverse(strArr); + +reversedStrs = [1, 2]; // Error! +``` + +実際、JavaScript配列には既に`.reverse`関数があり、TypeScriptはジェネリックを使ってその構造を定義しています: + +```ts +interface Array { + reverse(): T[]; + // ... +} +``` + +これは、以下のように任意の配列で `.reverse`を呼び出すときに型の安全性を得られることを意味します: + +```ts +var numArr = [1, 2]; +var reversedNums = numArr.reverse(); + +reversedNums = ['1', '2']; // Error! +``` + +後で、**アンビエント宣言**(Ambient Declarations)の節で`lib.d.ts`を説明するときに、`Array`インターフェースについてもっと議論します。 + +## ユニオン型(Union Type) +JavaScriptでは、プロパティを複数の型のうちの1つにしたいことがよくあります(例:`string`または`number`)。そういった場合、*ユニオン型*(型アノテーションの`|`を使い`string|number`のように書く)が便利です。よくある使用例として、単一のオブジェクトまたはオブジェクトの配列をとることができる関数があげられます。 + +```ts +function formatCommandline(command: string[]|string) { + var line = ''; + if (typeof command === 'string') { + line = command.trim(); + } else { + line = command.join(' ').trim(); + } + + // Do stuff with line: string +} +``` + +## 交差型(Intersection Type) +`オブジェクト拡張`(extend)はJavaScriptで非常に一般的なパターンです。ここでは2つのオブジェクトを取得し、これらのオブジェクトの両方の機能を持つ新しいオブジェクトを作成します。**交差型**では、以下に示すようにこのパターンを安全な方法で使用できます。 + +```ts +function extend(first: T, second: U): T & U { + return { ...first, ...second }; +} + +const x = extend({ a: "hello" }, { b: 42 }); + +// x now has both `a` and `b` +const a = x.a; +const b = x.b; +``` + +## タプル型 +JavaScriptには、第一級のタプルのサポートがありません。人々は、一般にタプルとして配列を使用します。これはまさにTypeScriptの型システムがサポートしているものです。タプルは、`: [typeofmember1, typeofmember2]`といったようにアノテーションを付けることができます。タプルには、任意の数のメンバを含めることができます。タプルの例: + +```ts +var nameNumber: [string, number]; + +// Okay +nameNumber = ['Jenny', 8675309]; + +// Error! +nameNumber = ['Jenny', '867-5309']; +``` + +これをTypeScriptの分解(Destructuring)のサポートと組み合わせると、タプルは、その実態は配列であるとはいえ、かなり第一級であるように感じられます: + +```ts +var nameNumber: [string, number]; +nameNumber = ['Jenny', 8675309]; + +var [name, num] = nameNumber; +``` + +## 型エイリアス(Type Alias) +TypeScriptは、複数の場所で使用したい型アノテーションの名前を提供するための便利な構文を提供します。エイリアスは `type SomeName = someValidTypeAnnotation`構文を使用して作成できます。例: + +```ts +type StrOrNum = string|number; + +// Usage: just like any other notation +var sample: StrOrNum; +sample = 123; +sample = '123'; + +// Just checking +sample = true; // Error! +``` + +`interface`とは違って、型エイリアスは文字通りどんな型アノテーションにも与えることができます(ユニオン型や交差型のようなものに便利です)。構文に慣れ親しむための例をいくつか次に示します。 + +```ts +type Text = string | { text: string }; +type Coordinates = [number, number]; +type Callback = (data: string) => void; +``` + +> ヒント:型アノテーションの階層を持つ必要がある場合は、`interface`を使います。インターフェースは`implements`と`extends`で使うことができます + +> ヒント:型エイリアスは、比較的単純なオブジェクト構造(`Coordinates`(座標)のような)にセマンティックな名前を付けるために使いましょう。また、ユニオン型や交差型にセマンティックな名前を付けたい場合に用いるのもよいでしょう。 + +## まとめ +これで、ほとんどのJavaScriptコードに型アノテーションを付けることができるようになりました。これで、TypeScriptの型システムで使用可能なすべての機能の詳細を説明できます。 diff --git a/docs/types/typeGuard.md b/docs/types/typeGuard.md new file mode 100644 index 000000000..5cc9e4354 --- /dev/null +++ b/docs/types/typeGuard.md @@ -0,0 +1,228 @@ +## Type Guard (Type Guards) +Type Guardを使用すると、条件ブロック内のオブジェクトの型を制限することができます。 + +### typeof + +TypeScriptはJavaScriptの`instanceof`と`typeof`演算子の使用を認識しています。条件付きブロックでこれらを使用すると、TypeScriptはその条件ブロック内で異なる変数の型を理解します。ここでは、TypeScriptが特定の関数が`string`に存在せず、おそらくユーザーのタイプミスであったことを指摘する簡単な例を示します: + +```ts +function doSomething(x: number | string) { + if (typeof x === 'string') { // Within the block TypeScript knows that `x` must be a string + console.log(x.subtr(1));

+foo.__proto__.bar = 456; + +console.log(foo.bar); // 123 +delete foo.bar; // オブジェクトから削除します +console.log(foo.bar); // 456 +delete foo.__proto__.bar; // foo.__proto__ から削除します +console.log(foo.bar); // undefined +``` + +これで、あなたは `__proto__`を理解できました。もう1つの便利な事実は、JavaScriptの関数\(`function`\)には`prototype`というプロパティがあり、そして、その`constructor`メンバは、逆に関数を参照しているということです。これを以下に示します: + +```typescript +function Foo() { } +console.log(Foo.prototype); // {} 例: これは存在しており、undefinedではありません +console.log(Foo.prototype.constructor === Foo); // `constructor` というメンバがあり、逆に関数を指しています +``` + +次に、呼び出された関数内の`this`に対して`new`が及ぼす影響を見てみましょう。基本的に、`new`を使って呼び出された関数の内側の`this`は、関数から返される新しく生成されたオブジェクトを参照します。関数内で`this`のプロパティを変更するのは簡単です: + +```typescript +function Foo() { + this.bar = 123; +} + +// new 演算子を使います +var newFoo = new Foo(); +console.log(newFoo.bar); // 123 +``` + +ここで理解しておくべきことは、関数に対する`new`の呼び出しにより、関数の`prototype`が、新しく生成されたオブジェクトの`__proto__`に設定されることです。次のコードを実行することによって、それを完全に理解できます: + +```typescript +function Foo() { } + +var foo = new Foo(); + +console.log(foo.__proto__ === Foo.prototype); // True! +``` + +これだけのことです。今度は`__extends`の抜粋を見てください。これらの行に番号を振りました: + +```typescript +1 function __() { this.constructor = d; } +2 __.prototype = b.prototype; +3 d.prototype = new __(); +``` + +この関数を逆から見ると、3行目の`d.prototype = new __()`は、 `d.prototype = {__proto__ : __.prototype}`を意味します\(`prototype`と`__proto__`に対する`new`の効果によるものです\)。それを2行目\(`__.prototype = b.prototype;`\)と組み合わせると、`d.prototype = {__proto__ : b.prototype}`となります。 + +しかし、待ってください。私達は、単に`d.prototype.__proto__`だけが変更され、`d.prototype.constructor`は、それまで通り維持されることを望んでいました。そこで重要な意味があるのが、最初の行\(`function __() { this.constructor = d; }`\)です。これによって`d.prototype = {__proto__ : __.prototype, constructor : d}`と同じことを実現できます\(これは関数の内側の`this`に対する`new`による効果のためです\)。したがって元の`d.prototype.constructor`を復元しているので、ここで変更されたものは、`__proto__`だけです。なので`d.prototype.__proto__ = b.prototype`となります。 + +### `d.prototype.__proto__ = b.prototype`の意味 + +これを行うことによって、子クラスにメンバ関数を追加しつつ、その他のメンバは基本クラスから継承することができます。次の簡単な例で説明します: + +```typescript +function Animal() { } +Animal.prototype.walk = function () { console.log('walk') };

+ +// 最初に思いつくであろう試みですが、正しくありません. その理由は下で説明します +function loadJSON(filename: string, cb: (error: Error, data: any) => void) { + fs.readFile(filename, function (err, data) { + if (err) cb(err); + else cb(null, JSON.parse(data)); + }); +} +``` + +十分にシンプルです。コールバックを引数に受け取り、ファイルシステムのエラーをコールバックに渡します。ファイルシステムのエラーがなければ、`JSON.parse`の結果を返します。コールバックに基づいて非同期関数を利用するときに注意すべき点は次のとおりです。 + +1. 決してコールバックを2回呼ばないでください。 +2. 決して Error を`throw`しないでください。 + +しかしながら、この単純な関数は2つ目の点に対応できません。実際にJSON.parseに間違ったJSONが渡されると、Error が`throw`され、コールバックが呼び出されず、アプリケーションがクラッシュします。これを以下の例で示します: + +```typescript +import fs = require('fs');

+ +// より改善したバージョンです。しかし、まだ正しくありません。 +function loadJSON(filename: string, cb: (error: Error) => void) { + fs.readFile(filename, function (err, data) { + if (err) { + cb(err); + } + else { + try { + cb(null, JSON.parse(data));

+}); +``` + +しかし、このコードには些細なバグがあります。もしコールバック\(`cb`\)が呼び出され、`JSON.parse`が呼び出されずに、エラーを`throw`した場合、`try`/`catch`で囲んでいるため、`catch`が実行され、コールバックを再度呼び出してしまいます。つまり、コールバックが二度呼び出されてしまいます!これを以下の例で示します: + +```typescript +import fs = require('fs'); + +function loadJSON(filename: string, cb: (error: Error) => void) { + fs.readFile(filename, function (err, data) { + if (err) { + cb(err); + } + else { + try { + cb(null, JSON.parse(data)); + } + catch (err) { + cb(err);

+ } + catch (err) { + return cb(err); + } + // コールバックを呼び出す時を除く + return cb(null, parsed); + }); +} +``` + +確かに何回か行えば、そう難しいことではありませんが、単に、良いエラー処理を書くためだけに、このような多くの定型的なコードが必要です。では、Promiseを使ってJavaScriptの非同期処理に取り組むための、より良い方法を見てみましょう。 + +## Promiseを作る + +Promiseの状態は、`pending`\(保留中\)または`fulfilled`\(履行済み\)または`rejected`\(拒絶済み\)のいずれかになります。 + +![Promiseの宣言と運命](https://raw.githubusercontent.com/basarat/typescript-book/master/images/promise%20states%20and%20fates.png) + +Promiseの作り方を見てみましょう。Promise\(Promiseのコンストラクタ\)に対して`new`を呼び出すだけです。Promiseのコンストラクタには、Promiseの状態を決めるための`resolve`関数と`reject`関数が渡されます。 + +```typescript +const promise = new Promise((resolve, reject) => { + // resolve / reject 関数がPromiseの運命を決定します +}); +``` + +### Promiseの結果を監視\(subscribing\)する + +Promiseの結果は、`.then`\(resolveが実行された場合\)または`.catch`\(rejectが実行された場合\)を使用して監視\(Subscribe\)できます。 + +```typescript +const promise = new Promise((resolve, reject) => { + resolve(123); +}); +promise.then((res) => { + console.log('I get called:', res === 123); // I get called: true +}); +promise.catch((err) => { + // これは呼び出されません +}); +``` + +```typescript +const promise = new Promise((resolve, reject) => { + reject(new Error("何かひどいことが起きた")); +}); +promise.then((res) => { + // これは呼び出されません +}); +promise.catch((err) => { + console.log('I get called:', err.message); // I get called: '何かひどいことが起きた' +}); +``` + +> TIP:Promiseのショートカット +> +> * すでにresolveされているPromiseをクイックに作成する:`Promise.resolve(result)` +> * 既にrejectされているPromiseをクイックに作成する: `Promise.reject(error)` + +### Promiseのチェーン + +Promiseのチェーンは**Promiseを使う最大のメリット**です。一度Promiseを取得すれば、その時点から、`then`関数を使ってPromiseのチェーンを作れます。 + +* もしチェーン内の関数からPromiseを返すと、そのPromiseがresolveされた時に1回だけ`.then`が呼び出されます: + +```typescript +Promise.resolve(123) + .then((res) => { + console.log(res); // 123 + return 456; + }) + .then((res) => { + console.log(res); // 456 + return Promise.resolve(123); // resolveされたPromiseを返しています + }) + .then((res) => { + console.log(res); // 123 : resolveされた値で`then`が呼び出されます + return 123; + }) +``` + +* チェーンの前の部分のエラー処理を単一の`catch`に集約することができます: + +```typescript +// rejectされたPromiseを作成する +Promise.reject(new Error('何か悪いことが起きた')) + .then((res) => { + console.log(res); // 呼び出されない + return 456; + }) + .then((res) => { + console.log(res); // 呼び出されない + return 123; + }) + .then((res) => { + console.log(res); // 呼び出されない + return 123; + }) + .catch((err) => { + console.log(err.message); // 何か悪いことが起きた + }); +``` + +* `catch`は実のところ新しいPromiseを返します\(要するに新しいPromiseのチェーンを作成します\): + +```typescript +// rejectされたPromiseを作成する +Promise.reject(new Error('何か悪いことが起きた')) + .then((res) => { + console.log(res); // 呼び出されない + return 456; + }) + .catch((err) => { + console.log(err.message); // 何か悪いことが起きた + return 123; + }) + .then((res) => { + console.log(res); // 123 + }) +``` + +* `then`\(または`catch`\)で同期エラーがスローされると、返されたPromiseが失敗します: + +```typescript +Promise.resolve(123) + .then((res) => { + throw new Error('何か悪いことが起きた'); // 同期処理でエラーを発生させる + return 456; + }) + .then((res) => { + console.log(res); // 呼び出されない + return Promise.resolve(789); + }) + .catch((err) => { + console.log(err.message); // 何か悪いことが起きた + }) +``` + +* エラーが発生すると関係している\(後方で最も近い\)`catch`だけがコールされます\(同時にcatchが新しい`Promise`のチェーンを作ります\)。 + +```typescript +Promise.resolve(123) + .then((res) => { + throw new Error('何か悪いことが起きた'); // 同期処理でエラーを発生させる + return 456; + }) + .catch((err) => { + console.log('first catch: ' + err.message); // 何か悪いことが起きた + return 123; + }) + .then((res) => { + console.log(res); // 123 + return Promise.resolve(789); + }) + .catch((err) => { + console.log('second catch: ' + err.message); // 呼び出されない + }) +``` + +* `catch`はチェーンの前部分でエラーが発生した場合にのみコールされます: + +```typescript +Promise.resolve(123) + .then((res) => { + return 456; + }) + .catch((err) => { + console.log("HERE"); // 呼び出されない + }) +``` + +Promiseチェーンに関する事実: + +* エラーが起きた場合、後続の`catch`にジャンプします\(そして途中の`then`はスキップします\) +* 同期処理のエラーについても同様に、最も近い後続の`catch`で捕捉されます + +Promiseは、単なるコールバックに比べて優れたエラー処理を可能にする非同期プログラミングのパラダイムを我々に提供してくれます。さらに下記に詳しく記載します。 + +### TypeScriptとPromise + +TypeScriptが素晴らしい点は、それがPromiseチェーンを通じて流れる値を理解してくれることです。 + +```typescript +Promise.resolve(123) + .then((res) => { + // res は `number` 型と推論される + return true; + }) + .then((res) => { + // res は `boolean` 型と推論される + + }); +``` + +もちろん、Promiseを返す可能性のある関数呼び出しも理解してくれます。 + +```typescript +function iReturnPromiseAfter1Second(): Promise { + return new Promise((resolve) => { + setTimeout(() => resolve("Hello world!"), 1000); + }); +} + +Promise.resolve(123) + .then((res) => { + // res は `number` 型と推論される + return iReturnPromiseAfter1Second(); // `Promise`を返す + }) + .then((res) => { + // res は `string` 型と推論される + console.log(res); // Hello world! + }); +``` + +### コールバック関数からPromiseを返すように変更する + +関数呼び出しをPromiseに包んで、下記のようにしてみましょう。 + +* エラーが発生した場合は `reject`を呼出す +* すべてうまく行った場合は`resolve`を呼び出す + +例えば`fs.readFile`をPromiseで囲んでみましょう: + +```typescript +import fs = require('fs'); +function readFileAsync(filename: string): Promise { + return new Promise((resolve,reject) => { + fs.readFile(filename,(err,result) => { + if (err) reject(err); + else resolve(result); + }); + }); +} +``` + +### JSONの例を見直す + +次に、`loadJSON`の例を見直して、Promiseを使う非同期バージョンを書いてみましょう。やるべきことは、Promiseとしてファイル内容を読み、JSONとしてパースする、それだけです。これを以下の例で示します: + +```typescript +function loadJSONAsync(filename: string): Promise { + return readFileAsync(filename) // 直前に作成した関数を使います + .then(function (res) { + return JSON.parse(res); + }); +} +``` + +使い方\(このセクションの始めに紹介した同期処理のコードとの違いに注目してください🌹\): + +```typescript +// 正しいjsonファイル +loadJSONAsync('good.json') + .then(function (val) { console.log(val); }) + .catch(function (err) { + console.log('good.json error', err.message); // 呼び出されない + }) + +// 存在しないjsonファイル + .then(function () { + return loadJSONAsync('absent.json'); + }) + .then(function (val) { console.log(val); }) // 呼び出されない + .catch(function (err) { + console.log('absent.json error', err.message); + }) + +// 正しくないjsonファイル + .then(function () { + return loadJSONAsync('invalid.json'); + }) + .then(function (val) { console.log(val); }) // 呼び出されない + .catch(function (err) { + console.log('bad.json error', err.message); + }); +``` + +この関数がよりシンプルになった理由は、"`loadFile`\(async\)+`JSON.parse`\(sync\)=>`catch`"の連結をPromiseチェーンによって行ったためです。また、コールバックは我々ではなくPromiseチェーンによって呼び出されるので、コールバックを`try/catch`で囲んでしまう誤りが起きる可能性はありませんでした。 + +### 並列制御フロー\(Parallel control flow\) + +私たちは、Promiseを使って非同期タスクの順次処理(シーケンシャル処理)を行うことがいかに簡単かを見てきました。単に`then`の呼び出しを連結するだけなのです。 + +しかし、複数の非同期処理を実行し、すべてのタスクが終わったタイミングで何らかの処理を行いたいケースがあるかもしれません。`Promise`は静的な`Promise.all`関数を提供します。この関数は、`n`個のPromiseがすべて完了するまで待つことができます。`n`個のPromiseの配列を渡すと、`n`個の解決された値の配列を返します。以下では、Promiseチェーンの例と合わせて並列で処理する例を示します。 + +```typescript +// 何らかのデータをサーバから読み込むことを再現する処理 +function loadItem(id: number): Promise<{ id: number }> { + return new Promise((resolve) => { + console.log('loading item', id); + setTimeout(() => { // サーバーからのレスポンス遅延を再現 + resolve({ id: id }); + }, 1000); + }); +} + +// Promiseチェーン +let item1, item2; +loadItem(1) + .then((res) => { + item1 = res; + return loadItem(2); + }) + .then((res) => { + item2 = res; + console.log('done'); + }); // 全体で 2秒 かかる + +// 並列処理 +Promise.all([loadItem(1), loadItem(2)]) + .then((res) => { + [item1, item2] = res; + console.log('done'); + }); // 全体で 1秒 かかる +``` + +ある場合には、複数の非同期タスクを実行するが、これらのタスクの内1つだけが完了すれば良いケースもあるでしょう。`Promise`は、このユースケースに対して`Promise.race`というStatic関数を提供しています: + +```typescript +var task1 = new Promise(function(resolve, reject) { + setTimeout(resolve, 1000, 'one'); +}); +var task2 = new Promise(function(resolve, reject) { + setTimeout(resolve, 2000, 'two'); +}); + +Promise.race([task1, task2]).then(function(value) { + console.log(value); // "one" + // 両方ともresolveされるが、task1の方が早く終わる +}); +``` + +### コールバック関数をPromiseに変換する + +これを行うために信頼性が高い方法は、自分でコードを書くことです。例えば`setTimeout`をPromiseを使った`delay`関数に変換するのは非常に簡単です: + +```typescript +const delay = (ms: number) => new Promise(res => setTimeout(res, ms)); +``` + +NodeJSにはこれを行う便利で使いやすい関数があることを知っておいてください。これは `コールバックスタイルの関数 => Promiseを返す関数` に変える魔法をかけてくれます。 + +```typescript +/** 利用例 */ +import fs = require('fs'); +import util = require('util'); +const readFile = util.promisify(fs.readFile);

JavaScriptの将来のバージョンで計画されている機能を、現在の\(モダンではない\)JavaScript環境でも使えるようにする + +では、なぜこれらのゴールが重要なのでしょうか?ここでは、これらのゴールを目指す動機について説明します。 + +## TypeScriptの型システム + +「**なぜJavaScriptに型を追加する必要があるのか?**」と疑問に思うかもしれません。 + +型は、コードの品質と読みやすさを高めることが実証されています。大規模なチーム\(Google、Microsoft、Facebook\)は、常にこの結論に至っています。具体的には以下の通りです: + +* 型は、リファクタリングをする際の開発スピードを高めます。型があることによって、コードを書いている時点でエラーに気づくことができます。そして、すぐにエラーを修正できます。ランタイム(実行時)で、はじめてエラーに気づいて、コードに戻って修正するよりも、ずっと効率的です。開発中に早い段階でエラーに気づけるということは非常に素晴らしいことです。 +* 型は、それ自体が、完璧なドキュメントです。_関数のシグネチャは定理であり、関数の本体は証明です。_ + +しかし、型には必要以上に儀式的な面があります。そのため、TypeScriptは、型を導入する障壁を可能な限り低くしています。次にそれを説明します。 + +### あなたの書いたJavaScriptはTypeScriptです + +TypeScriptは、JavaScriptコードのコンパイル時の型安全性を提供します。その名前はこれを表しています。TypeScriptが素晴らしい点は、型を利用するかどうかは、完全に任意(オプション)である、ということです。例えば、何らかのJavaScriptコードが書かれた`.js`ファイルを、`.ts`ファイルに名前を変更してコンパイルしたとしても、TypeScriptのコンパイラは、もとのJavaScriptファイルと同じ有効な`.js`を出力します。TypeScriptは、意図的な、かつ厳密な、JavaScriptのスーパーセット\(上位互換\)であり、任意の型チェックの仕組みを持ったプログラミング言語です。 + +### 暗黙的な型推論\(Type inference\) + +TypeScriptは、コーディングの生産性に対する影響をなるべく小さく抑えながら型の安全性を提供するために、可能な限り、型推論を行います。型推論とは、TypeScriptが、ソースコードを解析し、そのコードの流れから、変数や関数などの型を推測してくれる仕組みのことです。たとえば、次の例を見てください。この例では、TypeScriptは`foo`の変数の型が`number(数値)`であると推測します。そのため、2行目にエラーが表示されます。なぜなら、`number(数値)`に`string(文字列)`を代入しているからです: + +```typescript +var foo = 123; +foo = '456'; // エラー: `string` を `number` に代入できません + +// foo は number でしょうか? それとも string でしょうか? +``` + +型推論が必要とされることには、大きな理由があります。あるプロジェクトで、この例のようなコードを書いた場合、ほかの部分のコードで`foo`を扱うときに、それが`number`であるか`string`であるかが分かりません。このような問題は、大規模なプロジェクトで、よく発生します。TypeScriptは型を推論することによって、このような不明確なコードに対して、エラーを表示してくれます。後で、TypeScriptが行う型推論のルールについて、くわしく説明します。 + +### 明示的な型指定\(型アノテーション\) + +ここまでで述べたように、TypeScriptは、安全に行える場合は、できる限り、型を推論します。しかし、型推論の結果が正しくない場合、あるいは、正確でない場合は、開発者が、明示的にコード上で、型を指定する\(型アノテーションを書く\)ことができます。型アノテーションを書くことによって、以下のメリットを得ることができます: + +1. コンパイラの理解を助けるだけでなく、より、重要なことに、あなたが書いたコードを次に読まなくてはならない開発者にとってのドキュメントになります\(それは、将来のあなたかもしれません!\)。 +2. コンパイラがどのようにコードを理解するか、ということを強制します。つまり、コードに対する開発者の正しい理解を、コンパイラの型チェックのアルゴリズムに反映するということです。 + +TypeScriptは、ほかの任意な型付き言語\(ActionScriptやF\#など\)で一般的な、末尾型アノテーションを使用します。つまり、この例のように、対象の後ろにコロンをつけて、型を指定します: + +```typescript +var foo: number = 123; +``` + +型が一致しない場合は、コンパイラはエラーを出力します。VSCodeを使っていれば、エディター上にエラーが表示されます: + +```typescript +var foo: number = '123'; // エラー: `string` を `number` に代入できません +``` + +TypeScriptがサポートしている型アノテーションについては、このあとのセクションで詳しく説明します。 + +### 構造的な型\(Structural type system\) + +いくつかの言語\(特に型付き言語と呼ばれるもの\)において、静的な型付けは、必要以上に、儀式的なコードになってしまいます。なぜなら、コードが確実に正しく動作することが分かっている場合でも、構文ルールによって、同じようなコードをコピー&ペーストすることが強制されるからです。それは、たとえば、C\#の[automapper for C\#](http://automapper.org/)のようなものが必要になる理由です。TypeScriptは、JavaScript 開発者に対する認知的な負荷をなるべく小さくするため、構造的な型\(structural type\)を採用しています。これが意味することは、ダックタイピング\(duck typing\)が第一級\(言語レベルでサポートされている\)のものである、ということです。これを理解するため、次の例を見てみましょう。この関数`iTakePoint2D`は、必要なプロパティ\(この例では`x`と `y`\)を含むオブジェクトであれば、何でも引数として受け入れます: + +```typescript +interface Point2D { + x: number; + y: number; +} +interface Point3D { + x: number; + y: number; + z: number; +} +var point2D: Point2D = { x: 0, y: 10 } +var point3D: Point3D = { x: 0, y: 10, z: 20 } +function iTakePoint2D(point: Point2D) { /* なんらかの処理 */ } + +iTakePoint2D(point2D); // 全く同じ構造なので問題なし +iTakePoint2D(point3D); // 追加のプロパティがあっても問題なし +iTakePoint2D({ x: 0 }); // エラー: `y` が存在しない +``` + +### 型チェックでエラーがあってもJavaScriptは出力される + +JavaScriptのコードをTypeScriptに移行することを簡単にするため、デフォルトの設定では、コンパイルエラーがあったとしても、TypeScriptは有効なJavaScriptを出力します。例えば、次のコードを見てください。このコードにはエラーがあります。これをコンパイルすると: + +```typescript +var foo = 123; +foo = '456'; // エラー: `string` を `number` に代入できません +``` + +以下のJavaScriptが出力されます: + +```typescript +var foo = 123; +foo = '456'; +``` + +これによって、JavaScriptのコードを少しずつTypeScriptに移行することができます。これは他の言語のコンパイラとは全く異なる動作です。そして、これが、TypeScriptに移行する理由の1つです。 + +### アンビエント宣言\(declare\)によって、既存のJavaScriptライブラリでも型を利用できる + +TypeScriptの設計上の大きなゴールは、既存のJavaScriptライブラリであっても、安全かつ簡単に利用できるようにすることです。TypeScriptはこれを型宣言\(`declare`\)で行います。TypeScriptにおいて、型宣言にどれくらいの労力をかけるかは自由です。より多くの労力をかければ、より多くの型安全性と、IDEでのコード補完が得られます。ほとんど全ての有名なJavaScriptライブラリの型定義は、[DefinitelyTyped コミュニティ](https://github.com/borisyankov/DefinitelyTyped)によって既に作成されています。そのため、 + +1. 型宣言ファイル\(アンビエント宣言が書かれたファイル\)が既に存在します。 +2. あるいは、最低でも、きちんとレビューされた型宣言のテンプレートがすでに利用可能です。 + +独自の型宣言ファイルを作成する簡単な例として、[jquery](https://jquery.com/)の簡単な例を考えてみましょう。TypeScriptは、デフォルトの設定では、\(望ましいJavaScriptコードのように\)、変数を使う前に宣言する\(つまり、どこかで`var`を書く\)ことを期待しています。 + +```typescript +$('.awesome').show(); // エラー: `$` が存在しません。 +``` + +簡単な修正方法は、`declare`を使って、グローバル変数`$`が、実行時に必ず存在することをTypeScriptに伝えることです。 + +```typescript +declare var $: any; +$('.awesome').show(); // 問題なし! +``` + +必要に応じて、より詳細に型を定義することによって、プログラミングのエラーを防ぐことができます。 + +```typescript +declare var $: { + (selector: string): any; +}; +$('.awesome').show(); // 問題なし! +$(123).show(); // エラー: selector は string でなければなりません +``` + +TypeScriptの基本を理解した後で、既存のJavaScriptコードの型宣言を追加する方法について、詳しく説明します\(`interface`や`any`など\)。 + +## モダンなJavaScriptの機能を今すぐに利用できる + +TypeScriptは、古いJavaScript\(ES5以前\)の実行環境でも、ES6以降のバージョンで計画されている多くの機能を使えるようにしています。TypeScriptチームは積極的に機能を追加しています。機能は今後もどんどん増えていく予定です。これらについては独自のセクションで説明します。例えば、クラス構文\(ES6で追加された機能\)もその1つです: + +```typescript +class Point { + constructor(public x: number, public y: number) { + } + add(point: Point) { + return new Point(this.x + point.x, this.y + point.y); + } +} + +var p1 = new Point(0, 10); +var p2 = new Point(10, 20); +var p3 = p1.add(p2); // { x: 10, y: 30 } +``` + +かわいい太っちょのアロー関数もその1つです: + +```typescript +var inc = x => x+1; +``` + +### まとめ + +このセクションでは、TypeScriptを使う理由と、TypeScriptが目指しているゴールを説明しました。では、これから、TypeScriptが提供している機能や利便性について詳しく見ていきましょう。 + diff --git a/header.html b/header.html new file mode 100644 index 000000000..02d3a3ec5 ---

[https://docs.cypress.io/guides/references/assertions.html#Chai-jQuery](https://docs.cypress.io/guides/references/assertions.html#Chai-jQuery) です。

definitions 👍🏻 + +The complete list of chainers is available here : [https://docs.cypress.io/guides/references/assertions.html](https://docs.cypress.io/guides/references/assertions.html) + +If you want something complex you can even use `should(callback)` and e.g. + +``` +cy.get('div') + .should(($div) => { + expect($div).to.have.length(1); + expect($div[0].className).to.contain('heading'); + }) +// これは単なる例です。普通は`.should('have.class', 'heading')`のように書きます。 +``` + +> ヒント: cypressにはcallbackの呼び出しにも自動リトライ機能があるため、普通の文字列のチェーンと同じように壊れにくいコードを書くことができます。 + +## ヒント: コマンドとチェーン + +cypressチェーン内のすべての関数呼び出しは`command`です。`should`コマンドはアサーションです。チェーンとアクションの別々の_カテゴリ_を別々に開始することは慣習になっています: + +```typescript +// Don't do this +cy.get(/**something*/) + .should(/**something*/) + .click() + .should(/**something*/) + .get(/**something else*/) + .should(/**something*/) + +// Prefer separating the two gets +cy.get(/**something*/) + .should(/**something*/) + .click() + .should(/**something*/) + +cy.get(/**something else*/) + .should(/**something*/) +``` + +他の何かのライブラリは、同時にこのコードを評価し、実行します。それらのライブラリは、単一のチェーンが必要になります。それはセレクタやアサーションが混在してデバッグを行うのが難しくなります。 + +Cypressのコマンドは、本質的に、コマンドを後で実行するためのCypressランタイムへの_宣言_です。端的な言葉:Cypressはより簡単にします + +## ヒント: より容易なクエリのために`contains`を使う + +下記に例を示します: + +```typescript +cy.get('#foo') + // Once #foo is found the following: + .contains('Submit') + .click() + // ^ will continue to search for something that has text `Submit` and fail if it times out. + // ^ After it is found trigger a click on the HTML Node that contained the text `Submit`. +``` + +## ヒント: スマートディレイとリトライ + +Cypressはたくさんの非同期のものに対して、自動的に待ち(そしてリトライし)ます。 + +``` +// If there is no request against the `foo` alias cypress will wait for 4 seconds automatically +cy.wait('@foo') +// If there is no element with id #foo cypress will wait for 4 seconds automatically and keep retrying +cy.get('#foo') +``` + +これにより、テストコードフローに常に任意のタイムアウトのロジックを追加する必要がなくなります。 + +## ヒント: 暗黙のアサーション + +Cypressには暗黙のアサーションという概念があります。1つ前のコマンドが原因でそれ移行のコマンドでエラーが発生したときに実行されます。These kick in if a future command is erroring because of a previous command. E.g. the following will error at `contains` (after automatic retries of course) as nothing found can get `click`ed: + +```typescript +cy.get('#foo') + // Once #foo is found the following: + .contains('Submit') + .click() + // ^ Error: #foo does not have anything that `contains` `'Submit'` +``` + +伝統的なフレームワークでは、`null`には`click`がないというような恐ろしいエラーを目にすることでしょう。Cypressの場合、`#foo`には`Submit`が含まれていないという親切なエラーが表示されます。このようなエラーは暗黙のアサーションの一種です。 + +## ヒント: HTTPリクエストを待つ + +アプリケーションが作るXHRに必要なすべてのタイムアウトが原因となり、多くのテストが脆くなりました。`cy.server`は次のことを簡単にします。 + +* バックエンド呼び出しのエイリアスを作成する +* それらが発生するのを待つ + +例: + +```typescript +cy.server() + .route('POST', 'https://example.com/api/application/load') + .as('load') // create an alias + +// Start test +cy.visit('/') + +// wait for the call +cy.wait('@load') + +// Now the data is loaded +``` + +## ヒント: HTTPリクエストのレスポンスをモックする + +`route`を使ってリクエストのレスポンスを簡単にモックすることもできます: + +```typescript +cy.server() + .route('POST', 'https://example.com/api/application/load', /* Example payload response */{success:true}); +``` + +### ヒント: HTTPリクエストのレスポンスをアサートする + +リクエストのアサートは、モックを作らなくても`route`や`onRequest`/`onResponse`を使うことで実現できます。 + +```typescript +cy.route({ + method: 'POST', + url: 'https://example.com/api/application/load', + onRequest: (xhr) => { + // Example assertion + expect(xhr.request.body.data).to.deep.equal({success:true}); + } +}) +``` + +## ヒント: 時間をモックする + +`wait`を使ってある時間テストを一時停止することができます。自動的に"あなたはログアウトされます"という通知画面をテストする例: + +```typescript +cy.visit('/'); +cy.wait(waitMilliseconds); +cy.get('#logoutNotification').should('be.visible'); +``` + +しかし、`cy.clock`と時間をモックし、`cy.tcl`を使用して時間を前倒しすることが推奨されます: + +```typescript +cy.clock(); + +cy.visit('/'); +cy.tick(waitMilliseconds); +cy.get('#logoutNotification').should('be.visible'); +``` + +## ヒント: アプリケーションコードのユニットテスト + +あなたはCypressを使ってアプリケーションコードを分離してユニットテストを行うことも可能です。 + +```typescript +import { once } from '../../../src/app/utils'; + +// Later +it('should only call function once', () => { + let called = 0; + const callMe = once(()=>called++); + callMe(); + callMe(); + expect(called).to.equal(1); +}); +``` + +## ヒント: ユニットテストにおけるモック + +もしあなたがアプリケーショのモジュールをユニットテストしていたら、あなたは`cy.stub`を使ってモックを提供することが可能です。例えば、あなたは`navigate`が関数`foo`で呼ばれることを確認できます: + +* `foo.ts` + +```typescript +import { navigate } from 'takeme'; + +export function foo() { + navigate('/foo'); +} +``` + +* 下記を`some.spec.ts`で行います + +```typescript +/// + +import { foo } from '../../../src/app/foo'; +import * as takeme from 'takeme'; + +describe('should work', () => { + it('should stub it', () => { + cy.stub(takeme, 'navigate');

})`)や、ネットワーク呼び出し(`cy.request('https://someurl').then((res /* network response */) => { debugger });`)すら可能です。しかし、慣用的な方法は、`cy.get('#foo').debug()`です。そして、テストランナーが`debug`で止まったときに、`get`をコマンドログでクリックすると自動的に`console.log`にあなたが知りたい`.get('#foo')`に関する情報が出力されます(そして、デバッグに必要な他のコマンドでも似たようなものです) + +## ヒント: サーバーを開始してテストを実行する + +もしテストの前にローカルサーバーを起動したい場合は`start-server-and-test` [https://github.com/bahmutov/start-server-and-test](https://github.com/bahmutov/start-server-and-test) を依存関係に追加できます。それは次の引数を受け取ります。 + +* サーバーを実行するためのnpmスクリプト +* サーバーが起動しているかをチェックするためのエンドポイント +* テストを初期化するためのnpmスクリプト + +package.jsonの例: + +```javascript +{ + "scripts": { + "start-server": "npm start", + "run-tests": "mocha e2e-spec.js", + "ci": "start-server-and-test start-server http://localhost:8080 run-tests" + } +} +``` + +## リソース + +* ウェブサイト:[https://www.cypress.io/](https://www.cypress.io) +* あなたの最初のCypressテストを書く(Cypress IDEの素晴らしいツアー):[https://docs.cypress.io/guides/getting-started/writing-your-first-test.html](https://docs.cypress.io/guides/getting-started/writing-your-first-test.html) +* CI環境を設定する(例えば、そのまま`cypress run`で動く提供されたdockerイメージ):[https://docs.cypress.io/guides/guides/continuous-integration.html](https://docs.cypress.io/guides/guides/continuous-integration.html) +* レシピ(説明付きのレシピの一覧です。レシピのソースコードに移動するには見出しをクリックしてください): [https://docs.cypress.io/examples/examples/recipes.html](https://docs.cypress.io/examples/examples/recipes.html) +* Visual Testing: [https://docs.cypress.io/guides/tooling/visual-testing.html](https://docs.cypress.io/guides/tooling/visual-testing.html) +* Optionally set a `baseUrl` in cypress.json to [prevent an initial reload that happens after first `visit`.](https://github.com/cypress-io/cypress/issues/2542) +* Code coverage with cypress: [Webcast](https://www.youtube.com/watch?v=C8g5X4vCZJA) diff --git a/intro-1/jest.md b/intro-1/jest.md new file mode 100644 index 000000000..19e75313f --- /dev/null +++ b/intro-1/jest.md @@ -0,0 +1,206 @@ +# Jest + +> [Jest/TypeScriptに関するPro eggheadレッスン](https://egghead.io/lessons/typescript-getting-started-with-jest-using-typescript) + +パーフェクトなテストのソリューションはありません。とはいえ、jestは優れたTypeScriptサポートを提供する素晴らしいユニットテストのオプションです。 + +> 注意:単純なノードのpackage.json setupで始めることを前提としています。また、すべてのTypeScriptファイルは`src`フォルダに置かれていなければなりません。このフォルダは、きれいなプロジェクト設定のために(Jestを使わなくても)常に推奨されます。 + +## ステップ1:インストール + +npmを使用して次をインストールします。 + +``` +npm i jest @types/jest ts-jest -D +``` + +説明: + +* `jest`フレームワーク(`jest`)をインストールします +* `jest`の型(`@types/jest`)をインストールします +* Jest用のTypeScriptプリプロセッサ(`ts-jest`)をインストールします。これにより、Jestはその場でTypeScriptをトランスパイルすることができ、source-mapをサポートします +* これらのすべてを、あなたのdevの依存関係に保存してください(テストはほとんど常にnpmのdev-dependencyです) + +## ステップ2:Jestを設定する + +次の`jest.config.js`ファイルをプロジェクトのルートに追加します: + +```javascript +module.exports = { + "roots": [ + "/src" + ], + "testMatch": [ + "**/__tests__/**/*.+(ts|tsx|js)", + "**/?(*.)+(spec|test).+(ts|tsx|js)" + ], + "transform": { + "^.+\\.(ts|tsx)$": "ts-jest" + }, +} +``` + +説明: + +* 私達は_すべての_TypeScriptファイルをプロジェクトの`src`フォルダに入れることを常にお勧めします。また、これに倣い`roots`設定では`src`フォルダを指定します。 +* `testMatch`設定は、ts/tsx/jsフォーマットで書かれた.test/.specファイルを発見するためのglobのパターンマッチャーです。 +* `transform`設定は、ts/tsxファイルに対して`ts-jest`を使うよう`jest`に指示します。 + +## 手順3:テストを実行する + +あなたのプロジェクトのルートから`npx jest`を実行すると、jestはあなたのテストを実行します。 + +### オプション:npmスクリプトのスクリプトターゲットを追加する + +`package.json`に追加してください: + +```javascript +{ + "test": "jest" +} +``` + +* これにより、簡単な`npm t`でテストを実行できます。 +* また、`npm t --watch`のwatchモードでも。 + +### オプション:watchモードでjestを実行する + +* `npx jest --watch` + +### 例 + +* `foo.ts`ファイルの場合: + +```javascript +export const sum + = (...a: number[]) => + a.reduce((acc, val) => acc + val, 0);

+var bar: foo.SomeType; +``` + +しかし、あるいは実行時に特定の場合だけ`foo`をロードしたいかもしれません。そのような場合には、`import`した名前を型アノテーションとしてのみ使用し、変数として使用しないでください。これにより、TypeScriptにより挿入される実行時依存関係をすべて削除します。そして、あなたは独自のモジュールローダーに固有のコードを書いて実際のモジュールを手動でインポートします。 + +例として、次の`commonjs`ベースのコードを考えてみましょう。このコードでは、特定の関数が呼び出された時だけ`'foo'`モジュールをロードします: + +```typescript +import foo = require('foo'); + +export function loadFoo() { + // `foo` を遅延ロードします。そして、オリジナルのモジュールは型アノテーションとして *だけ* 利用します。 + var _foo: typeof foo = require('foo'); + // これで、 `foo` の代わりに `_foo` を変数として扱うことができます。 +} +``` + +`amd`\(requirejsを使用\)での同様のサンプルは次のようになります: + +```typescript +import foo = require('foo'); + +export function loadFoo() { + // `foo` を遅延ロードします。そして、オリジナルのモジュールは型アノテーションとして *だけ* 利用します。 + require(['foo'], (_foo: typeof foo) => { + // これで、 `foo` の代わりに `_foo` を変数として扱うことができます。 + }); +} +``` + +このパターンは一般的に使用されます。 + +* Webアプリケーションにおいて、特定のルートの場合のみ特定のJavaScriptをロードする +* Nodeアプリケーションにおいて、アプリケーションの起動を高速化したい場合に、特定のモジュールだけをロードする + +## ユースケース:循環依存を避ける + +遅延ロードの使用例と同様に、特定のモジュールローダ\(commonjs/nodeと、amd/requirejs\)は循環依存のため、うまく動作しません。そのような場合には、1つの方向に遅延ロードを行うようにし、反対方向のロードの前にロードしておくと便利です。 + +## ユースケース:確実にインポートする + +場合によっては、副作用のためだけにファイルをロードすることもできます\(例えば[CodeMirror addons](https://codemirror.net/doc/manual.html#addons)のように、モジュールを他のライブラリに登録させる場合など\)。しかし、単に`import/require`を行うと、コンパイルされたJavaScriptがモジュールに依存しておらず、モジュールバンドラ\(例えばwebpack\)が、そのインポートを完全に無視してしまうかもしれません。このような場合、例えば下記のように `ensureImport`変数を使用して、コンパイルされたJavaScriptがモジュールに依存するようにすることができます。 + +```typescript +import foo = require('./foo');

+boolArray = 'false'; // Error! +boolArray = [true, 'false']; // Error! +``` + +### インターフェース\(Interfaces\) + +インターフェースは、複数の型アノテーションを単一の名前付きアノテーションに合成するための、TypeScriptにおける主要な方法です。次の例を考えてみましょう。 + +```typescript +interface Name { + first: string; + second: string; +} + +var name: Name; +name = { + first: 'John', + second: 'Doe' +}; + +name = { // Error : `second` is missing + first: 'John' +}; +name = { // Error : `second` is the wrong type + first: 'John', + second: 1337 +}; +``` + +ここでは、アノテーションを`first: string` + `second: string`という新しいアノテーション`Name`にまとめて、個々のメンバの型チェックを行っています。インターフェースはTypeScriptで大きなパワーを持っているので、別途専用のセクションでその利点をどのように活かすかを説明します。 + +### インライン型アノテーション\(Inline Type Annotation\) + +新しい`interface`を作成するのではなく、構造`:{/* Structure */}`を使って_インライン_で必要なものにアノテーションを付けることができます。前の例を、インライン型で再掲します: + +```typescript +var name: { + first: string; + second: string; +}; +name = { + first: 'John', + second: 'Doe' +}; + +name = { // Error : `second` is missing + first: 'John' +}; +name = { // Error : `second` is the wrong type + first: 'John', + second: 1337 +}; +``` + +インライン型は、1回だけ使うようなアノテーションを素早く提供するのに最適です。それは\(良くないかもしれない\)型名を考える手間を省きます。しかし、同じ型アノテーションを複数回インラインで入れている場合は、それをインターフェース\(またはこのセクションの後半で説明する`type alias`\)にリファクタリングすることを検討することをお勧めします。 + +## 特殊な型 + +上記でカバーしたプリミティブ型以外にも、TypeScriptでは特別な意味を持ついくつかの型があります。これらは`any`、`null`、`undefined`、`void`です。 + +### any + +`any`型は、TypeScript型システムにおいて特別なものです。これは、型システムからの脱出口を与えて、コンパイラに失せるよう指示します。`any`は型システムのすべての型と互換性があります。つまり、any型の変数には_何でも代入できる_し、その変数を_何にでも代入できる_ということです。以下に例を示します: + +```typescript +var power: any; + +// Takes any and all types +power = '123'; +power = 123; + +// Is compatible with all types +var num: number; +power = num; +num = power; +``` + +JavaScriptコードをTypeScriptに移植する場合、最初は`any`と友達になります。しかし、型安全性を確保することはあなた次第であるため、この友情を真剣に受け止めてはいけません。これを使うことは、基本的に、コンパイラに意味のある静的解析を行わないように指示することです。 + +### `null`と`undefined` + +`strictNullChecks`フラグ\(このフラグについては、後で扱います\)によって扱いが変わります。`strictNullChecks`が`false`の場合、`null`と`undefined`のJavaScriptリテラルは、型システムにおいては`any`型と同じようなものとして扱われます。これらのリテラルは他の型に代入することができます。以下に例を示します: + +```typescript +var num: number; +var str: string; + +// These literals can be assigned to anything +num = null; +str = undefined; +``` + +### `:void` + +関数に戻り値の型がないことを示すには`:void`を使います: + +```typescript +function log(message): void { + console.log(message); +} +``` + +## ジェネリックス\(Generics\) + +コンピュータサイエンスの多くのアルゴリズムとデータ構造は、オブジェクトの実際の型に依存しません。しかし、それでも、あなたは、さまざまな変数の間で制約を適用したいと考えているでしょう。単純なおもちゃの例は、項目のリストを取り、逆順にした項目のリストを返す関数です。ここでの制約は、関数に渡されるものと関数によって返されるものの間の制約です。 + +```typescript +function reverse(items: T[]): T[] { + var toreturn = []; + for (let i = items.length - 1; i >= 0; i--) { + toreturn.push(items[i]); + } + return toreturn; +} + +var sample = [1, 2, 3]; +var reversed = reverse(sample); +console.log(reversed); // 3,2,1 + +// Safety! +reversed[0] = '1'; // Error! +reversed = ['1', '2']; // Error! + +reversed[0] = 1; // Okay +reversed = [1, 2]; // Okay +``` + +ここでは、`reverse`関数は何らかの型`T`の配列\(`items: T[]`\)を受け取り\(`reverse`の型パラメータに注目\)、`T`型の配列を返します\(`: T[]`に注目\)。 `reverse`関数は、同じ型の項目を返すので、`reversed`変数も`number[]`型であることがTypeScriptに分かるため、型の安全性が得られます。同様に`string[]`の配列を`reverse`関数に渡すと、返される結果も`string[]`の配列になり、以下に示すような型安全性が得られます: + +```typescript +var strArr = ['1', '2']; +var reversedStrs = reverse(strArr); + +reversedStrs = [1, 2]; // Error! +``` + +実際、JavaScript配列には既に`.reverse`関数があり、TypeScriptはジェネリックを使ってその構造を定義しています: + +```typescript +interface Array { + reverse(): T[]; + // ... +} +``` + +これは、以下のように任意の配列で `.reverse`を呼び出すときに型の安全性を得られることを意味します: + +```typescript +var numArr = [1, 2]; +var reversedNums = numArr.reverse(); + +reversedNums = ['1', '2']; // Error! +``` + +後で、**アンビエント宣言**\(Ambient Declarations\)の節で`lib.d.ts`を説明するときに、`Array`インターフェースについてもっと議論します。 + +## ユニオン型\(Union Type\) + +JavaScriptでは、プロパティを複数の型のうちの1つにしたいことがよくあります\(例:`string`または`number`\)。そういった場合、_ユニオン型_\(型アノテーションの`|`を使い`string|number`のように書く\)が便利です。よくある使用例として、単一のオブジェクトまたはオブジェクトの配列をとることができる関数があげられます。 + +```typescript +function formatCommandline(command: string[]|string) { + var line = ''; + if (typeof command === 'string') { + line = command.trim(); + } else { + line = command.join(' ').trim(); + } + + // Do stuff with line: string +} +``` + +## 交差型\(Intersection Type\) + +`オブジェクト拡張`\(extend\)はJavaScriptで非常に一般的なパターンです。ここでは2つのオブジェクトを取得し、これらのオブジェクトの両方の機能を持つ新しいオブジェクトを作成します。**交差型**では、以下に示すようにこのパターンを安全な方法で使用できます。 + +```typescript +function extend(first: T, second: U): T & U { + return { ...first, ...second }; +} + +const x = extend({ a: "hello" }, { b: 42 }); + +// x now has both `a` and `b` +const a = x.a; +const b = x.b; +``` + +## タプル型 + +JavaScriptには、第一級のタプルのサポートがありません。人々は、一般にタプルとして配列を使用します。これはまさにTypeScriptの型システムがサポートしているものです。タプルは、`: [typeofmember1, typeofmember2]`といったようにアノテーションを付けることができます。タプルには、任意の数のメンバを含めることができます。タプルの例: + +```typescript +var nameNumber: [string, number]; + +// Okay +nameNumber = ['Jenny', 8675309]; + +// Error! +nameNumber = ['Jenny', '867-5309']; +``` + +これをTypeScriptの分解\(Destructuring\)のサポートと組み合わせると、タプルは、その実態は配列であるとはいえ、かなり第一級であるように感じられます: + +```typescript +var nameNumber: [string, number]; +nameNumber = ['Jenny', 8675309]; + +var [name, num] = nameNumber; +``` + +## 型エイリアス\(Type Alias\) + +TypeScriptは、複数の場所で使用したい型アノテーションの名前を提供するための便利な構文を提供します。エイリアスは `type SomeName = someValidTypeAnnotation`構文を使用して作成できます。例: + +```typescript +type StrOrNum = string|number; + +// Usage: just like any other notation +var sample: StrOrNum; +sample = 123; +sample = '123'; + +// Just checking +sample = true; // Error!

+``` + +この単純な`declare var`の後に、変数名\(ここでは`window`\)とアノテーションで指定されているインターフェース\(`Window`インターフェース\)が続きます。これらの変数は、一般的にグローバルなインターフェースを指し示しています。例として、ここに`Window`インターフェースの小さな\(実際には非常に大規模な\)サンプルを提示します: + +```typescript +interface Window extends EventTarget, WindowTimers, WindowSessionStorage, WindowLocalStorage, WindowConsole, GlobalEventHandlers, IDBEnvironment, WindowBase64 { + animationStartTime: number; + applicationCache: ApplicationCache; + clientInformation: Navigator; + closed: boolean; + crypto: Crypto; + // so on and so forth... +} +``` + +これらのインターフェースには、たくさんの型情報があることがわかります。TypeScriptが存在しない場合、これを頭で覚えておかなければなりません。コンパイラが理解している知識を、インテリセンスや自動補完のようなもので容易にアクセスできるようにすることができます。 + +これらのグローバルにインターフェースを使用していることは良いことです。なぜなら、`lib.d.ts`を変更することなく、これらのグローバルのインターフェースにプロパティを追加することができるからです。次に、この概念について説明します。 + +### ネイティブ型\(Native Types\)を変更する + +TypeScriptの`interface`はオープンエンドなので、`lib.d.ts`で宣言されたインターフェースにメンバを追加するだけで、TypeScriptはその追加を認識します。これらのインターフェースを`lib.d.ts`に関連付けるには、これらの変更を [グローバルモジュール](../project/modules/) で行う必要があることに注意してください。このために、 [`global.d.ts`](../project/modules/globals.md) という特別なファイルを作成することをお勧めします。 + +ここでは、 `window`、`Math`、`Date`に要素を追加する例をいくつか示します: + +#### `window`の例 + +単に`Window`インターフェースにものを追加します: + +```typescript +interface Window { + helloWorld(): void; +} +``` + +これにより、あなたはそれを安全な方法で使うことができます: + +```typescript +// Add it at runtime +window.helloWorld = () => console.log('hello world'); +// Call it +window.helloWorld(); +// Misuse it and you get an error: +window.helloWorld('gracius'); // Error: Supplied parameters do not match the signature of the call target +``` + +#### `Math`の例 + +グローバル変数`Math`は`lib.d.ts`で定義されています\(再度、あなたの開発ツールを使って定義に移動してください\): + +```typescript +/** An intrinsic object that provides basic mathematics functionality and constants. */ +declare var Math: Math; +``` + +すなわち、変数`Math`は`Math`インターフェースのインスタンスです。`Math`インターフェースは次のように定義されています: + +```typescript +interface Math { + E: number; + LN10: number; + // others ... +} +``` + +つまり、グローバル変数の`Math`に物を追加したいのであれば、それをグローバルインターフェースの`Math`に追加するだけです。[`seedrandom`プロジェクト](https://www.npmjs.com/package/seedrandom) を参考に、グローバル`Math`オブジェクトに`seedrandom`関数を追加してください。これは非常に簡単に宣言できます: + +```typescript +interface Math { + seedrandom(seed?: string); +} +``` + +これで、それを使うことができます: + +```typescript +Math.seedrandom(); +// または +Math.seedrandom("何らかの文字列"); +``` + +#### `Date`の例 + +`lib.d.ts`の`Date`変数の定義を見ると、次のようになっています: + +```typescript +declare var Date: DateConstructor; +``` + +`DateConstructor`というインターフェースは、`Date`グローバル変数を使って使うことができるメンバが含まれている点で、`Math`と`Window`で見たものに似ています。 例えば`Date.now()`です。これらのメンバに加えて、`Date`インスタンス\(例えば`new Date()`\)を作成するためのコンストラクタのシグネチャが含まれています。 `DateConstructor`インターフェースの断片を以下に示します: + +```typescript +interface DateConstructor { + new (): Date; + // ... その他の構成シグネチャ + + now(): number; + // ... その他のメンバー関数 +} +``` + +[`datejs`](https://github.com/abritinthebay/datejs) というプロジェクトを例にして考えてみましょう。 DateJSは、メンバを`Date`グローバル変数と`Date`インスタンスの両方に追加します。したがって、このライブラリのTypeScriptの定義は、以下のようになります\(ところで、[コミュニティはすでにそれをあなたのために書いています](https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/datejs/index.d)\): + +```typescript +/** DateJS Public Static Methods */ +interface DateConstructor { + /** Gets a date that is set to the current date. The time is set to the start of the day (00:00 or 12:00 AM) */ + today(): Date; + // 続く +} + +/** DateJS Public Instance Methods */ +interface Date { + /** Adds the specified number of milliseconds to this instance. */ + addMilliseconds(milliseconds: number): Date; + // 続く +} +``` + +これにより、型安全な方法で次のようなことができます: + +```typescript +var today = Date.today(); +var todayAfter1second = today.addMilliseconds(1000); +``` + +#### `string`の例 + +文字列の `lib.d.ts`を調べると、`Date`\(`String`グローバル変数、`StringConstructor`インターフェース、`String`インターフェース\)のようなものが見つかるでしょう。しかし、注意すべき点の1つは、以下のコードサンプルで示すように、`String`インターフェースは、文字列リテラルに対しても影響がある、という点です: + +```typescript +interface String { + endsWith(suffix: string): boolean; +} + +String.prototype.endsWith = function(suffix: string): boolean { + var str: string = this; + return str && str.indexOf(suffix, str.length - suffix.length) !== -1; +} + +console.log('foo bar'.endsWith('bas')); // false +console.log('foo bas'.endsWith('bas')); // true +``` + +同様の変数とインターフェースは、`Number`、`Boolean`、`RegExp`などの静的メンバとインスタンスメンバの両方を持つ他のものにも存在し、これらのインターフェースはこれらの型のリテラルのインスタンスにも影響します。 + +### `string`後方一致の例 + +メンテナンス上の理由から、`global.d.ts`を作成することを推奨しました。しかし、あなたが望むのであればファイルモジュールの中からグローバルな名前空間に入れることができます。これは`declare global {/ * global namespace here * /}`を使って行います。例えば。前の例は次のようにすることもできます: + +```typescript +// Ensure this is treated as a module. +export {}; + +declare global { + interface String { + endsWith(suffix: string): boolean; + } +} + +String.prototype.endsWith = function(suffix: string): boolean { + var str: string = this; + return str && str.indexOf(suffix, str.length - suffix.length) !== -1; +} + +console.log('foo bar'.endsWith('bas')); // false +console.log('foo bas'.endsWith('bas')); // true +``` + +### 独自のカスタムlib.d.tsを使用する + +前に述べたように、 `--noLib`のコンパイラフラグを使用すると、TypeScriptは自動的に`lib.d.ts`を除外します。これが有用である理由はさまざまです。一般的なもののいくつかを以下に示します。 + +* 標準ブラウザベースのランタイム環境とは大きく異なるカスタムJavaScript環境で実行する場合 +* コード内で使用可能なグローバルを厳密に制御したい場合。例えばlib.d.tsは`item`を大域変数として定義していますが、あなたはそれをコードに混入させたくないでしょう + +デフォルトの `lib.d.ts`を除外すると、コンパイルコンテキストに同様の名前のファイルを含めることができ、TypeScriptは型チェックのためにそれを取り込みます。 + +> 注意: `--noLib`には注意してください。一度noLibを使ったら、あなたのプロジェクトを他の人と共有しようとしたとき、noLibを\(またはあなたのLibを\)使うことを強制することになります。さらに悪いことに、もし彼らのコードをプロジェクトに持っていこうとすると、あなたのlibに基づくコードに変換する必要があるかもしれません。 + +### コンパイラターゲットの`lib.d.ts`に対する効果 + +コンパイラのターゲットを `es6`に設定すると`lib.d.ts`は`Promise`のようなより現代的なもの\(es6\)のための環境宣言を追加します。コンパイラターゲットがコードの環境を変えるという魔法の効果は、一部の人にとっては望ましいことです。他の人にとっては、コードと環境を合わせないといけないので、問題があります。 + +しかしそれでも、あなたの環境をきめ細かく制御したい場合は、次に述べる`--lib`オプションを使うべきです。 + +### libオプション + +場合によっては、コンパイルターゲット\(生成されたJavaScriptのバージョン\)と環境ライブラリサポートの関係を切り離したい場合があります。2016年6月において一般的な例は、`Promise`です。たいていは`--target es5`のようにすることを望むと思います。しかし、それでも、`Promise`のような最新の機能を使いたい場合、これをサポートするために、`lib`コンパイラオプションを使って`lib`を明示的に制御することができます。 + +> 注意: `--lib`を使うと、`--target`のlibの魔法を切り離して、より細かい制御ができます。 + +このオプションをコマンドラインまたは`tsconfig.json`に指定することができます\(それを推奨します\)。 + +**コマンドライン**: + +```text +tsc --target es5 --lib dom,es6 +``` + +**tsconfig.json** : + +```javascript +"compilerOptions": { + "lib": ["dom", "es6"] +} +``` + +libsは次のように分類できます。 + +* JavaScriptのバルク機能: + * es5 + * es6 + * es2015 + * es7 + * es2016 + * es2017 + * esnext +* 実行時環境 + * dom + * dom.iterable + * webworker + * scripthost +* ESNext By-Featureオプション\(バルク機能よりも小さい\) + * es2015.core + * es2015.collection + * es2015.generator + * es2015.iterable + * es2015.promise + * es2015.proxy + * es2015.reflect + * es2015.symbol + * es2015.symbol.wellknown + * es2016.array.include + * es2017.object + * es2017.sharedmemory + * esnext.asynciterable + +> 注意: `--lib`オプションは非常に細かく調整された制御を提供します。したがって、たいていは、バルク機能と環境カテゴリから対象を選択すれば良いでしょう。 --libが指定されていない場合、デフォルトのライブラリが選択されます: +> +> * --target es5の場合 => es5、dom、scripthost +> * --target es6の場合 => es6、dom、dom.iterable、scripthost + +私の個人的な推奨: + +```javascript +"compilerOptions": { + "target": "es5", + "lib": ["es6", "dom"] +} +``` + +ES5にシンボル\(Symbol\)を含む例: + +ターゲットがes5の場合、Symbol APIは含まれません。実際のところ`[ts]Cannot find name 'Symbol'`ようなエラーが表示されます。 "target": "es5"と "lib"を組み合わせて、TypeScriptにSymbol APIを提供することができます: + +```javascript +"compilerOptions": { + "target": "es5", + "lib": ["es5", "dom", "scripthost", "es2015.symbol"] +} +``` + +## 古いJavaScriptエンジン用のポリフィル + +> [この件に関するEgghead PRO Video](https://egghead.io/lessons/typescript-using-es6-and-esnext-with-typescript) + +`Map`/`Set`や、`Promise`\(このリストは当然変更されるでしょう\)のような、いくつかのランタイム機能は、モダンな`lib`オプションで使用できるものがかなりあります。これらを使うには `core-js`を使うだけです。単に、インストールしてください: + +```text +npm install core-js --save-dev +``` + +また、アプリケーションのエントリポイントにインポートを追加します。 + +```javascript +import "core-js";
