These are the slides from Johannes Weber's talk which were presented on AngularJS Lightning Talks #2 (2014-06-26) in Munich. More details about the event: http://www.meetup.com/AngularJS-Munich/events/164424472/

1. AngularJS with RequireJS
in practice

3. Preview Take-aways
‣ AngularJS injects instances
‣ RequireJS injects classes
‣ Keep testing in mind when organizing your app structure

4. Is RequireJS really needed?
‣ Simple & small apps
‣ The whole code in one file
‣ Load all packages manually <script src=“…“></script
What about large apps…

5. … like apps with more classes?

6. Schrift in weiß oder grau. Darauf achten, dass Text auf Motiv
lesbar bleibt.
Thema
It’s time for…
$ bower install requirejs

7. 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

8. define([dep1], function(dep1) {})
All your files are wrapped in a define()
define() must return a Object which is cached in a registry

9. 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

10. require.config()
RequireJS configuration (path to sources, caching, etc.)
Configuration or aliases and shims

11. „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)

12. 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

13. Organize the app

14. Example: Modules main.js & index.js

15. Controller Example

16. Example: Controller

17. Example on Github
‣ https://github.com/feibeck/StarshipMayflower

18. 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)

19. 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

20. Lazy load approaches
