  • 6. RequireJS + AngularJS Maintainable JavaScript Application = oxymoron?Apply the same principles of good software engineering to angularjs apps.JavaScript is very flexible, very easy to write undisciplined code (and architecture) – be strict!
  • 7. PrinciplesEach file should contain one (and one only) component – directive, filter, service, controller, view etc.Split out components into smaller components (each own file).Spilt out the app into smaller apps – We use our API’s to integrate app.Use RequireJS to manage the dependencies and loading of libs and your components
  • 8. RequireJS SetupAll code at https://github.com/cymantic/angular-require- testacular
  • 9. Directory Structureindex.html (the require script tag goes here)--libs --angular --jquery --require require-jquery.js (jQuery loaded here) --domReady (needed in some browsers when scripts loaded before dom is ready)--scripts (your components) --controller --directives --filters --resources --servicesapp.js (angular module of app defined here)bootstrap.js (manual bootstrapping of the app)main.js (require configuration and route configuration)--styles--templates--views
  • 10. <script data-main="./scripts/main.js" src="libs/require/require-jquery.js"></script>(we are not yet optimizing the files into a single file – todo before beta launch)main.js
  • 11. app.js – first non-library to load, we define our module herebootstrap.js – manually start up the application
