  5. 5.• Demo
  6. 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. 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. 8. RequireJS SetupAll code at testacular
  9. 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. 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. 11. app.js – first non-library to load, we define our module herebootstrap.js – manually start up the application
