AngularJS

UÁT?

● Open Source Javascript Framework

● Aims for making “simple” apps and SPAs development easier

● Does it by extending HTML itself

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)

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

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

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

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

● 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?

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.

…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

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.
