How to use injected services in static methods

Question

I want to use angularjs and typescript together. I'm trying to create Orm factory with typescript and stacked with some problem.

I defined my factory class as:

class OrmModel implements IOrmModel { static $inject = ['$http', '$q', 'config']; private name:string; private isNewRecord:boolean = false; constructor(public $http:ng.IHttpService, private $q:ng.IQService, private config:Object) { //... } static findAll(params:ISearchParams, relations:string[]):ng.IPromise<OrmModel> { //... } }

Here I defined factory.

OrmModule:ng.IModel = angular.module('core.orm', []); OrmModule.factory('OrmModel', ['$http', '$q', OrmModel]);

How can I use $http or $q in findAll() method?

Notice: with a class, you should use myModule.service('OrmModel', OrmModel). — Paleo

Using a dependency from a static function is a bad idea. However, you can declare a static variable private static $http;, then, in the constructor, do : OrmModel.$http = $http; — Paleo

I think, I should use service like this myModule.service('OrmModel', new OrmModel()), because services in angular most of all are singletons — Ivan Burnaev

To live in the angular ecosystem singletons should be services. So move the findAll function into its own service. That way it can have access to other services like $http and $q.

You don't recommend working with singletones even if we are coding typescript? Isn't there any way to get access to injected parameter while working with typescript singletones?
