AngularJs console.log “$q is not defined”

Question

I am getting this error in the console $q is not defined. When I did some research I found some thing like .q library has been deprecated from http://

Answer 1

Promises are not deprecated. In fact they're gaining quite a lot of momentum lately and are included in the next version of JavaScript.

Let's look at what they say:

This breeze.angular.q library has been deprecated. It is superseded by the Breeze Angular Service which more cleanly configures breeze for Angular development.

The Breeze Angular Service tells Breeze to use Angular's $q for promises and to use Angular's $http for ajax calls.

What they say is that breeze uses Angular's own promises for promises rather than its own breeze.angular.q which uses Q promises which are more able but also much heavier than $q promises which Angular uses. This is simply an API change.

Inside Angular code, you can obtain $q using dependency injection - for example with the simple syntax:

myApp.controller("MyCtrl",function($q){
    //$q is available here
});

Alternatively, if you want to use it independently you can use service location and obtain $q directly from an injector, but that's rarely the case. (If you want an example - let me know, I'd just rather not include code that's usually indicative of bad practice).
