javascript - How to get typescript to recognize a custom action on the angular $resource? -

this sample use of angular $resource in typescript. in example i'm attempting create update action on resource i've defined, it's done in https://docs.angularjs.org/api/ngresource/service/$resource. i'm returning instance ng.resource.iresourceclass<ivenueresource>

module app.common {     interface ivenueservice{      }     export interface ivenueresource extends ng.resource.iresource<app.domain.ivenue>{       update(ivenue: app.domain.ivenue) : app.domain.ivenue;     }      export class venueservice implements ivenueservice{       static $inject = ["$resource", "url"];       constructor(private $resource: ng.resource.iresourceservice, private url: url_constants){       }      getvenueresource(): ng.resource.iresourceclass<ivenueresource>{       // define custom action iactiondescriptor       var updateaction : ng.resource.iactiondescriptor = {           method: 'put',           isarray: false       };       return <ng.resource.iresourceclass<ivenueresource>>       this.$resource(this.url.base_api+"/v1/venues/:id", {id: '@id'} ,{         update: updateaction       });     }   }   angular     .module("common.services")     .service("venueservice", venueservice); } 

now time use resource, resource defined interface implemented class. yet still error, how typing dictionary recognize update method.

module app.venue {    interface inavigationscope{     venueresource: ng.resource.iresourceclass<app.common.ivenueresource>;   }    class venuelistctrl implements inavigationscope {     venueresource: ng.resource.iresourceclass<app.common.ivenueresource>;   }   sample(){     var updatedvenue =this.venueresource.update({id: 1, name: 'amphitheather'},        ()=> {});   } } 

soon realized reference https://github.com/definitelytyped/definitelytyped/blob/master/angularjs/angular-resource.d.ts#l85

i should using iresourceclass<iresource<t>> extend interface, because iresource<t> not have option add custom method.

interface iresourceclass<t> {         new(dataorparams? : any) : t;         get(): t;         ... } 

furthermore, when using custom method, needed assign correct declaration.

interface inavigationscope{ venueresource: app.common.ivenueresource; } 

returning instance of ivenueresourceclass child of ng.resource.iresourceclass<ng.resource.iresource<app.domain.ivenue>> update() method.
