Building ColdFusion And AngularJS Applications
- 1. Building ColdFusion and AngularJS Applications Mike Collins SupportObjective CFSummit October 2014
- 2. Today’s Agenda Walkthrough Requirements for a CF AngularJS Application Build our ColdFusion REST Server side Building the API Testing the API Build AngularJS the Client side Intro to AngularJS Core AngularJS features Build and Demo AngularJS using CF REST Wrap up
- 3. Our Project Requirements Player Registration Application – New Player Registration – Player Manager – ColdFusion 11 Server Side – AngularJS 1.3 Client Side – Use SQL DB to store data – Use REST API with JSON
- 4. Client-side and Server-side FRONTEND BACKEND Angular Clients JSON JSON REST API to receive Use $http service to and deliver JSON call backend REST API
- 5. Team Development Approach • The Client-side team and Server-Side team met and decided on an API • Parallel independent development • The Client side will use AngularJS ngMock to mock server-side communication until server side is ready • Server-side can test the REST API using cfhttp or jMeter to test until the client side is ready
- 6. Building the ColdFusion REST based Server Side
- 7. ColdFusion Server Side Features • What does CF bring to the server side • ColdFusion RESTFUL Features • Provide your applications dynamic pages • Backend Integration to JDBC, LDAP, Web Services, Email, PDF Services, JSON • Improve Security with encrypted request tokens • Seed applications with initial loading of data • Dynamically build AngularJS apps with CF
- 8. ColdFusion RESTful Features • New feature added in CF10 • Ability to create REST services by defining certain attributes in the tags – cfcomponent – cffuntion – cfargument • RESTful Function Signatures • Supports JSON and XML serialization/deserialization • Client applications can consume REST services by issuing HTTP/HTTPS requests format • Also - other CF REST options exist such as TAFFY
- 9. Creating a CF REST Component 1. Define CFC as REST and define a restpath attribute <cfcomponent rest="true" restpath="playerService"> 2. Define REST function 3. Define REST <cffunction name="getPlayer" access="remote“ httpmethod="GET“ restpath="getPlayer/{playerID}" returntype="any" produces="application/json"> function arguments <cfargument name="playerID“ required="true" restargsource="Path" type="numeric"/ >
- 10. Understanding RestArgPath • CFFunction aguments can be retrieved from multiple places • Path, Query String, Form, Cookie, Header <cfargument name="playerID“ required="true" restargsource="Path" type="numeric"/ >
- 11. REST Component Registration • Need to register your REST CFCs in CFAdmin • Using 2 new settings in Application.cfc – <cfset this.restsettings.cfclocation = “./, ./rest"> – <cfset this.restsettings.skipcfcwitherror = true>
- 12. Processing REST Requests • /Rest is a new servlet mapping in web.xml • How REST requests are processed with Application.cfc Method Processed OnRequestStart Yes OnRequest No OnError Yes OnCFCRequest No OnRequestEnd Yes
- 13. CF RESTful HTTP Post Example AngularJS APP <cffunction name="newPlayer" access="remote" httpmethod="POST" restpath="newPlayer" returntype="any" returnformat="json"> <cfargument name="playerData" required="true" type="string" /> <cfif not isJSON(arguments.playerData)> <cfreturn errorjson("-1000","Request Error Code 1000 - Invalid JSON #arguments.playerData#")> </cfif> <!--- Deserialize JSON ---> <cfset jsondata = deserializeJSON( arguments.playerData )> …
- 14. ColdFusion 11 JSON Improvements • JSON improvements – Data type preservation for Query and CFC – Case preservation of struct keys – Added "Struct" as new QueryFormat • Which is the format AngularJS expects – Ability to define custom JSON serializer http://blogs.coldfusion.com/post.cfm/language-enhancements-in-coldfusion-splendor-improved-json-serialization-2
- 15. Server-side Testing • CFHTTP scripts • jMeter Load Testing
- 16. About AngularJS
- 17. About AngularJS • Adapts and extends HTML • Some of the key features: – two-way data-binding – synchronizes model data and views – Filters for client side data – http ajax call features • Follows a MVC pattern – loose coupling between presentation, data, and logic components. • A complete client-side JavaScript solution • Managed by a developer team at Google Igor and Miska from Google
- 19. AngularJS Popularity Project contributors per month
- 20. AngularJS Reach • Browser support – Safari – Chrome – Firefox – Opera – IE8, IE9 – Mobile browsers Android, Chrome Mobile, iOS Safari • AngularJS 1.3 does not support IE 8
- 21. Getting AngularJS Go to Angularjs.org to download http://angularjs.org
- 22. Optional Add-on Modules • Loaded after the coreangular.js file: – angular-animate.js - Enable animation support – angular-cookies.js - A convenient wrapper for reading and writing browser cookies – angular-resource.js - Interaction support with RESTful services via the $resource service – angular-route.js - Routing and deep linking services and directives for angular apps – angular-sanitize.js - Functionality to sanitize HTML – angular-touch.js - Touch events and other helpers for touch-enabled devices – New angular-messages.js – helps with displaying informative error messages with forms
- 23. Works well with Others
- 24. Many Server-side Integration Points Angular Clients http resource websockets services factories restful Cloud Services
- 25. A Simple AngularJS App <script type="text/javascript" src="/js/angular.min.js"></script> <h1>Simple Data Binding with AngularJS</h1> <div ng-app> Name: <input type="text" ng-model="name" /> Welcome to AngularJS {{name}} </div> http://cfangular.com/simple/databinding.cfm
- 26. Getting Started Resources • Dan Wahlin – AngularJS in 60ish Minutes – https://www.youtube.com/watch?v=i9MHigUZKEM • All the ng-conf sessions – https://www.youtube.com/results?search_query=ng-conf • AngularJS FAQ – https://docs.angularjs.org/misc/faq
- 27. Building the AngularJS Frontend
- 28. Frontend / Clientside Team • They have been busy writing the front end using ngMock waiting for the Server API to be completed – ngMock as an AngularJS module to mock backend communication • Now let’s hook the frontend with the ColdFusion REST server api • Check out this blog for using ngmock with CF – http://www.sagarganatra.com/2014/06/angularjs-resolving-data-services.html
- 29. AngularJS Startup • Loading an AngularJS page builds our scopes and bindings Backend Providers SERVER REST API Datastore
- 30. AngularJS Features the team used 2 way Data Binding Model - Form Filters Player Finder Controllers Each route gets its own ngRoute – ngView Load dynamic CF pages Ng-repeat Directive Custom Date Directive $http service Get and Post JSON $http interceptor Catch all server traffic Form Processing Validation and messaging Built in Form CSS Classes Ng-show directive Ng-disable directive
- 31. Our AngularJS Home <html ng-app="playerApp"> <head> <!-- Load CSS other JS here--> <!-- Load Angular and Angular Routes Module --> <script src="vendor/angular.min.js"></script> <script src="vendor/angular-route.min.js"></script> <!-- Load main AngularJS application js --> <script src="js/app.js"></script> </head> <body ng-controller="mainController"> --- </body> </html>
- 32. Routes and Controllers and ngView <body ng-controller="mainController"> <nav class="navbar navbar-default"> <div class="container"> <div class="navbar-header"> <a class="navbar-brand" href="/">Player Registration Manager</a> </div> <ul class="nav navbar-nav navbar-right"> <li><a href="#"><i class="fa fa-home"></i> Home</a></li> <li><a href="#register"><i class="fa fa-shield"></i> Register Player</a></li> <li><a href="#manager"><i class="fa fa-comment"></i> Manager Players</a></li> </ul> </div> </nav> <div id="main"> <div ng-view class="parialview"></div> </div> </body>
- 33. Using Routes and Controllers mainController playerApp.controller('mainController', function($scope) { $scope.message = 'I am the home page!'; }); Home.cfm <div class="jumbotron text-center"> <h1>Home Page</h1> <p>{{ message }}</p> </div> http://cfangular.com/playerapp/ App.js playerApp.config(function($routeProvider) { $routeProvider // route for the home page .when('/', { templateUrl : 'partials/home.cfm', controller : 'mainController' }) // route for the register page .when('/register', { templateUrl : 'partials/register.cfm', controller : 'registerController' }) // route for the player manager page .when('/manager', { templateUrl : 'partials/manager.cfm', controller : 'managerController' }); });
- 34. AngularJS $http Features • $http Caching • $http Interceptors • $http Headers • $http Security – Built in JSON vulnerability protection – Built in XSRF protection
- 35. Calling the ColdFusion RESTful API $scope.updatePlayer = function() { if ($scope.manageForm.$valid){ $http.post('/rest/playerService/updatePlayer?callback=JSON_CALLBACK', $scope.player). success(function(data, status) { $scope.status = data.status; $scope.message = data.message; }) .error(function(data, status) { alert(data.MESSAGE ); $scope.data = data || "Update failed"; $scope.status = status; }) } else{ alert('Please correct fields in red and then resubmit form'); } }
- 36. Using a AngularJS Filters • We call into CF and load the playerlist array • Define the filter for a data listing <tr class="playerRow" ng-repeat="p in playerList | filter:search | orderBy:'playerfirstname' " ng-click="getPlayer(p.id)"> <td>{{p.playerfirstname | uppercase}} {{p.playerlastname}}</td> <td>{{p.playerleague}}</td> <td>{{p.currentteam}}</td> </tr> • Assign the filter to some user input Search: <input ng-model="search.$"> <select data-ng-model="search.currentteam"> <option ng-repeat="t in teams“ value="{{t.name}}">{{t.name}}</option> </select> • When user selects a team only players on that team appear
- 37. AngularJS Form Features • Built-in CSS classes – ng-valid, ng-invalid, ng-pristine, ng-dirty • Built-in Validations – url, email, max, maxlength, min, minlength, number, pattern, required • Input Properties – $valid, $invalid, $pristine, $dirty – $error{} – contains field data for all invalid fields – ngmessages – new in 1.3 https://docs.angularjs.org/api/ngMessages • Methods – $setValidity(), $setPristine(), $setDirty(),$addControl(), $removeControl()
- 38. ngModel and Form Bindings $scope.search = ''; $scope.player = {}; $scope.player['securitytoken'] = '' ; $scope.player['playerfirstname'] = 'Mike'; $scope.player['playerlastname'] = 'Smith'; . Binding to the model in a form input <input class="cfang-input cfang-input100" name="playerlastname" type="text" ng-model="player.playerlastname“ value="{{player.playerlastname}}" placeholder="Last Name" ng-required='1==1' >
- 39. Angular Form Code Example • A CF page using AngularJS Form Features • Input validation • ngShow to show or hide based on form being valid • Binding to model
- 40. What have we seen • Angular App Design • Forms Model Binding • Form Validation • Form CSS classes • AngularJS Filters • Using JSON • Authentication • CF Restful API • Error Handling • Services • Factories • $http • $resource • Interceptors
- 41. Working with client-side data • AngularJS makes it easy to work with large amounts of data on the client • Concurrency may become an issue
- 42. Real Time Channel • Easily hook in other JS to build real time – HTML5 websockets – Node.js – Express Routing framework – Socket.io • Real time Services – Firebase
- 43. Building in Security • Custom request tokens • AngularJS $http interceptors • Security tools and techniques – ZAP Application to test your RESTful api – Pete Frietag’s Using Custom Security Headers • Using Google Chrome Batarang – View data in controller scopes – View performance metrics
