2. AngularJS with RequireJS in practice @jowe Johannes Weber Mayflower GmbH
4. Preview Take-aways ‣ AngularJS injects instances ‣ RequireJS injects classes ‣ Keep testing in mind when organizing your app structure
5. Is RequireJS really needed? ‣ Simple & small apps ‣ The whole code in one file ‣ Load all packages manually <script src=“…“></script What about large apps…
6. … like apps with more classes? http://andrewgelman.com/2009/06/30/visualizing_tab/
7. Schrift in weiß oder grau. Darauf achten, dass Text auf Motiv lesbar bleibt. Thema It’s time for… $ bower install requirejs
8. 3 RequireJS APIs which you need to know ‣ define() 
 define & register dependencies ‣ require() 
 callback function invoked when all defines() have completed ‣ config() 
 configure source paths, shims and aliases
9. define([dep1], function(dep1) {}) All your files are wrapped in a define() define() must return a Object which is cached in a registry
10. require([dep1], function(dep1) {}) Act as initialization or root of the dependency tree Starts the cascade of dependency checks and script loading Starts the cascade of define() triggers
11. require.config() RequireJS configuration (path to sources, caching, etc.) Configuration or aliases and shims
12. „RequireJS is a JavaScript file and module loader.“
 (load and runtime dependency) „AngularJS comes with a built-in dependency injection mechanism.“
 (construction and ng module dependency)
13. Hot to use it with AngularJS? ‣ Use define() around all your code ‣ Use require.config() to set your paths & config ‣ Use require() to launch your initialize your App https://github.com/tnajdek/angular-requirejs-seed
14. Organize the app
15. Example: Modules main.js & index.js
16. Controller Example
17. Example: Controller
18. Example on Github ‣ https://github.com/feibeck/StarshipMayflower
19. r.js - the RequireJS Optimizer ‣ Build & deploy RequireJS Apps ‣ Deploy uncompressed ‣ Deploy concatenate & uglified ‣ Plugins available for ‣ grunt (grunt-requirejs) ‣ gulp(gulp-requirejs) ‣ broccoli (broccoli-requirejs)
20. Challenges on huge apps ‣ AMD is not just JavaScript, also CSS and Templates
 RequireJS provides plugins for that ‣ Growing app size from trivial to complex
 could be solved by partitioned modules ‣ On-demand load and unload modules
 Currently very difficult ‣ AngularJS 2.0 - deferred loading with ES6 annonations
21. Lazy load approaches ‣ https://github.com/ifyio/angularjs-lazy-loading-with-requirejs ‣ https://github.com/szhanginrhythm/angular-require-lazyload ‣ https://github.com/stu-salsbury/angular-couch-potato/
