ic-ajax

ic-ajax

Ember-friendly jQuery.ajax wrapper.

• returns RSVP promises
• makes apps more testable (resolves promises with Ember.run)
• makes testing ajax simpler with fixture support

Installation

bower install ic-ajax

... or ...

npm install ic-ajax

Module Support

Note the dist directory has multiple module formats, use whatever works best for you.

• AMD

  define(['ic-ajax'], function(ajax) {});

• Node.JS (CJS)

  var ajax = require('ic-ajax')

• Globals

  var ajax = ic.ajax;

  All instructure canvas stuff lives on the ic global.

API

This lib simply wraps jQuery.ajax with two exceptions:

• success and error callbacks are not supported
• does not resolve three arguments like $.ajax (real promises only resolve a single value). request only resolves the response data from the request, while raw resolves an object with the three "arguments" as keys if you need them.

Other than that, use request exactly like $.ajax.

var ajax = ic.ajax;

App.ApplicationRoute = Ember.Route.extend({
  model: function() {
    return ajax.request('/foo');
  }
}

// if you need access to the jqXHR or textStatus, use raw
ajax.raw('/foo').then(function(result) {
  // result.response
  // result.textStatus
  // result.jqXHR
});

Ember Data

By default, if Ember Data is on the page, ic-ajax will override the RESTAdapter's ajax method to use ic-ajax instead of jQuery's ajax.

To opt out of the behavior, you can set ic.ajax.request.OVERRIDE_REST_ADAPTER = false after loading ic-ajax.

Simplified Testing

In order to test newly added code you must rebuild the distribution.

broccoli build dist

Adding fixtures with defineFixture tells ic-ajax to resolve the promise with the fixture matching a url instead of making a request. This allows you to test your app without creating fake servers with sinon, etc.

Example:

ic.ajax.defineFixture('api/v1/courses', {
  response: [{name: 'basket weaving'}],
  jqXHR: {},
  textStatus: 'success'
});

ic.ajax.request('api/v1/courses').then(function(result) {
  deepEqual(result, ic.ajax.lookupFixture('api/v1/courses').response);
});

To test failure paths, set the textStatus to anything but success.
