This document discusses LoopBack, an API framework for Node.js that is based on Express. It provides an overview of what needs to be installed to use LoopBack, including Node.js, VS Code, an API testing client, and MySQL. It then discusses LoopBack's core functionality and modules for modeling data, application initialization, middleware execution, connecting to data sources, integration, and client SDKs. It also covers how to create a LoopBack application, define models and relationships, connect models to data sources, and implement user authentication and access control.

What need to be installed • NodeJS v8.x LTS • VS Code - https://code.visualstudio.com/ • Insomnia REST client - https://insomnia.rest/ • Loopback CLI [sudo] npm install -g loopback-cli@latest • MySQL Database v5.6 or higher • HeidiSQL / PHPMyAdmin / Sequel Pro
- 3. Loop what? Let’s talk in Express • The Node.js API Framework. • One of the framework that based from the famous web JavaScript framework, ExpressJS. • Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. • Comply with Open API specification mostly • http://nodeframework.com/index.html#rest-api
- 4. The Core
- 6. Framework Modules Category Description Use to… Modules Models Model and API server Dynamically mock-up models and expose them as APIs without worrying about persisting. loopback Abstraction Model data abstraction to physical persistence Connect to multiple data sources or services and get back an abstracted model with CRUD capabilities independent of backing data source. loopback-datasource-juggler Initialization Application initialization Configure data sources, customize models, configure models and attach them to data sources; Configure application settings and run custom boot scripts. loopback-boot Sequencing Middleware execution Configure middleware to be executed at various points during application lifecycle. loopback-phase Data RDBMS and noSQL physical data sources Enable connections to RDBMS and noSQL data sources and get back an abstracted model. •loopback-connector-mongodb •loopback-connector-mysql •loopback-connector- postgresql •loopback-connector-msssql •loopback-connector-oracle •Many others… Integration General system connectors Connect to an existing system that expose APIs through common enterprise and web interfaces •loopback-connector-rest •loopback-connector-soap Components Add-ons to core LoopBack Integrate with pre-built services packaged into components. •loopback-component-push •loopback-component-storage •loopback-component-passport Clients Client SDKs Develop client app using native platform objects (iOS, Android, AngularJS) that interact with LoopBack APIs via REST. •loopback-sdk-ios •loopback-sdk-android •loopback-sdk-angular
- 7. Data Sources and Connectors
- 8. Create New “lb app”
- 12. Hooking up to real Datasource
- 13. Auto-migrate / Auto-update 'use strict'; module.exports = function(app) { app.dataSources.<ds name>.autoupdate(‘<modelname>’, err => { if (err) throw err; }); };
- 14. Establishing relationship • lb relation 1 to 1 1 to many Many to many • Through table
- 15. User based model • Build-in model in framework • Basic authentication, ACL and AccessToken ready
