AngularJS is an open source JavaScript framework maintained by Google and the community. It aims to make developing simple single-page applications easier by extending HTML. The framework guides developers to decouple DOM manipulation from application logic and client/server code. It promotes declarative programming and two-way data binding between views and models. While powerful for CRUD apps, it takes longer to fully learn and provides less flexibility than some alternatives. Overall, AngularJS is well-designed for quickly building quality dynamic web applications, especially those following its model-view conventions.

1. AngularJS

2. UÁT?
● Open Source Javascript Framework
● Aims for making “simple” apps and SPAs
development easier
● Does it by extending HTML itself

3. Bai rro?
● Miško Hevery @ Google, 2009
● Used @ Google to write an app in 3 weeks
(1 dev) while it took 6 months (3 devs)
● Open sourced on Github (with 362 open PRs
just yesterday)

4. UÁI?
● A self-claimed opinionated JS framework
(while Backbone.js presents itself as library)
● Maintained by Google and community
● Don’t believe everyone, Angular and
your code doesn’t HAVE to be ugly

5. The Zen of Angular
● Decouple DOM manipulation from app logic,
as well as client and server sides code
● The framework should guide the developer
● Make common tasks trivial, difficult tasks
possible

10. How does it work?
● Since HTML is great for static pages,
Angular makes it amazing for dynamics too
● Add directives (built-in or custom) to HTML
● Declarative programming for your interface

11. How does it work?
● Modularize your business code with Model-
View-Glue architecture
● Take advantage of routers, partials and all
the nice stuff
● Imperative programming for your app’s code

12. ● Native two-BELOVED-way data binding <3
● In one side the View observes and shows
model’s state, in another it also notifies the
Controller of any user interaction and the
controller manages the model to do the
server-side part (also built-in form
validation!)
How does it work?

13. Worth mentioning: pros...
● Easy to learn and get started
● Testing support and incentive
● Agnostic, modularized and small JS code
● Google and community support
● Great philosophy
● Guides, but doesn’t lock!
● D.R.Y.

14. …and cons
● Takes longer to fully learn since it provides
many “native” modules for a complete
dynamic web app
● Angular abstraction comes at a cost of
flexibility, it was built with the CRUD
application in mind, keep this in mind

15. Silver bullet?
Well designed for sure, in a time of modern
Javascripts frameworks it surely is a great
competitor and, for the kind of problems it
wants to solve/help/guide, probably the best
choice for a quick development with quality code.
