angular-q-timeout

Adds .timeout method to promises returned by Angular $q service

Example

// module('my module', ['ng-q-timeout'])

foo()
.timeout(100, function (defer) {
  defer.reject('foo timed out');
  // probably run $scope.$apply here too
})
.then(function () {
  // foo has finished ok
}, function (msg) {
  // foo has failed or timed out.
});

Inspired by Extending Q promises, I have decided to add timeout method to promises returned by the $q service.

Install

bower install ng-q-timeout

include the script after angular

<script src="bower_components/angular/angular.js"></script>
<script src="ng-q-timeout.js"></script>

add ng-q-timeout module as a dependency to your application

angular.module('Example', ['ng-q-timeout'])

Limitations

Currently only the first promise returned by the $q.defer() is extended with timeout method. Thus always set timeout first, like the example above. This will NOT work

foo()
.then(...)
.timeout(100, function (defer) {
  defer.reject('foo timed out');
});
// throws an error, timeout should go before .then

I am using window.setTimeout internally, which means the timeout callback happens outside the $apply loop. If you need to update the ui in the callback function, call $scope.$apply there.
