$Ohttp - Simple wrapper (with cancellation) for using observables for http in Angular 1 today...

$Ohttp.js

angular.module('$Ohttp',[]).factory('$Ohttp', function($http, $q) {
	var $Ohttp = function(settings) {
		var defer = $q.defer();
		return Rx.Observable.create(function(observer) {
			$http(angular.extend(settings,{
				timeout:defer.promise
			})).then(function(response) {
				observer.next(response);
				observer.complete();
			},function(err) {
				observer.error(err);
			});
			return function unsubscribe() {
				defer.resolve();
			};
		});
	}
	return $Ohttp;
});

Beware that the $Ohttp-observable is cold, so it wont do the request until someone subscribes...

//Dependencies are angular and RxJS5

Usage:

angular.module('myApp',['$Ohttp']).service('myService', function($Ohttp) {

  $Ohttp({
    url:'/api/something'
  }).subscribe(function(response) {
    console.log(response.data);
  });

});
