Ember.js Router API v2

WARNING

This gist is outdated! For the most up-to-date information, please see http://emberjs.com/guides/routing/!

It All Starts With Templates

An Ember application starts with its main template. Put your header, footer, and any other decorative content in application.handlebars.

<header>
# ROUTER
GWS.Router.map (match) ->
#match("/").to("home") # home.handlebars gets rendered automatically and mapped to /
# according to guide the previous logic shouldn't be needed. but it won't work without it
# you can either use model: () -> or
# setupController: (controller, model) ->
# controller.set 'content', model

Ember APIs

JSON API

There are two JSON API styles:

  • The ID Style
  • The URL Style

The ID style is the easiest to get started with, but requires that your clients be able to guess the URLs for related documents. It also locks your API into a particular URL structure, which may become a problem as your API grows.

The URL style requires less guessing on the client side, and makes clients more resilient to API changes, but is trickier to use with relationships and compound documents.
