Ember-friendly jQuery.ajax
wrapper.
- returns RSVP promises
- makes apps more testable (resolves promises with
Ember.run
) - makes testing ajax simpler with fixture support

Server side package is a Broccoli.js plugin that concatinates all of the fixtures into a single file that you can consume in your browser app.
npm install --save-dev qd-ajax
In your Brocfile.js
var concatFixtures = require('qd-ajax');
// concatFixtures( inputTree, moduleName, outputFile )
return concatFixtures('fixtures', 'fixtures', '/fixtures.js');
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, whileraw
resolves an object with the three "arguments" as keys if you need them.
Other than that, use request
exactly like $.ajax
.
var ajax = qd.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
});
By default, if Ember Data is on the page, qd-ajax will override the
RESTAdapter
's ajax
method to use qd-ajax instead of jQuery's ajax.
To opt out of the behavior, you can set qd.ajax.request.OVERRIDE_REST_ADAPTER = false
after loading qd-ajax.
Adding fixtures with defineFixture
tells qd-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:
qd.ajax.defineFixture('api/v1/courses', {
response: [{name: 'basket weaving'}],
jqXHR: {},
textStatus: 'success'
});
qd.ajax.request('api/v1/courses').then(function(result) {
deepEqual(result, qd.ajax.lookupFixture('api/v1/courses').response);
});
To test failure paths, set the textStatus
to anything but success
.
You can reset defined fixtures between tests with qd.ajax.resetFixtures()
.
module('testing calls', {
setup: function() {
qd.ajax.resetFixtures();
}
});
By default, qd.ajax resolves responses synchronously. To simulate real world asynchronous requests, you can use the delay helper or activate default delay with qd.ajax.request.DELAY_RESPONSE=true
. You can also set the default delay time with qd.ajax.request.DELAY_TIME=3000;
;
Delay helper returns promise that will resolve after period of time specified by time parameter. The time parameter is optional and defaults to 250ms.
qd.ajax.defineFixture('api/v1/courses', function(){
return this.delay({
response: [{name: 'basket weaving'}],
jqXHR: {},
textStatus: 'success'
}, 300);
});
Return jQuery.ajax compatible success response.
qd.ajax.defineFixture('api/v1/courses', function() {
return this.success([{name: 'basket weaving'}]);
});
Return jQuery.ajax compatible error response.
qd.ajax.defineFixture('api/v1/courses', function() {
return this.error();
});
Install dependencies and run tests with the following:
npm install
npm test
