Import a third-party library not available on npm in Ionic 2 rc

Question

I have an external JS file containing some methods and integration of third-party libraries. Now I want to include this JS file as a module in my Ionic 2 rc build project. The following steps were as follows:

• declare module 'Appgeneral'; in file src/declarations.d.ts

• Including tag <script>in index.htmlsince this is a js file

• Creating an object in home.ts:var appgeneral = new Appgeneral();

• Appgeneral.js contains the following code:

  function Appgeneral(){}
  Appgeneral.prototype.methodCall = function() {
          console.log("Done!");
          return true;
  };
  

Methods must be available in home.tsusing the newly created object appgeneral. It worked great in beta.11. However, after upgrading to the rc build, I get an error message that the module cannot resolve appgeneral.

In addition, I converted mine Appgeneral.jsto Appgeneral.tsexport the entire class as follows:

module Appgeneral{
   export class Appgeneral{
     public methodCall() {
        console.log("Done!");
        return true;
     }
   }
}

home.ts : import { Appgeneral } from './src/ts/Appgeneral'. , .

"Appgeneral".       L14: (public navCtrl: NavController,       L15: public appgeneral: Appgeneral) {

, , , npm. .
