After upgrading TypeScript, Angular controller registration now fails to compile

Question

We were using TypeScript 2.2. After upgrading to 2.4, we now get this on compilation:

error TS2345: Argument of type \'typeof TopMenuController\' is not

Answer 1

I also faced the same issue which I got resolved by

• implementing IController

• add this code before constructor (or anywhere in code this is my preference) $onInit = () => { };

here is the full code, Hope this will give a clear view

module MyApp {
    export class HomeController implements angular.IController {
        $onInit = () => { };
        user: string;
        constructor() {
            this.user = "mali";
        }
    }
    angular.module('app').controller('homeController', MyApp.HomeController)
}

Happy Coding
