Angular $q allSettled() implementation similar to https://github.com/kriskowal/q/wiki/API-Reference#promiseallsettled

q-all-settled.js

angular.module('qAllSettled', []).config(function($provide) {
  $provide.decorator('$q', function($delegate) {
    var $q = $delegate;
    $q.allSettled = function(promises) {
      return $q.all(promises.map(function(promise) {
        return promise.then(function(value) {
          return { state: 'fulfilled', value: value };
        }, function(reason) {
          return { state: 'rejected', reason: reason };
        });
      }));
    };
    return $q;
  });
});

$q.all accepts an array or hash of promises, whereas this implementation of allSettled will only work when promises is an array of promises. An alternative could be as follows:

      $q.allSettled = function(promises) {
        var wrappedPromises = angular.isArray(promises) ? promises.slice(0) : {};
        angular.forEach(promises, function(promise, index){
          wrappedPromises[index] = promise.then(function(value){
            return { state: 'fulfilled', value: value };
          }, function(reason){
            return { state: 'rejected', reason: reason };
          })
        });
        return $q.all(wrappedPromises);
      };

@ryanhart2 Your version is better but it should also consider "non-thenables" as successfully resolved values.

Implemented this and added it to the bower registry:
