What is the best way to tap into an external module in typescript?

I have a document that includes a module structured as follows

ROOT/database/models.ts

module Model {
  export interface Inbox {
    title: string;
    msg: string;
  }
  export interface User{
    Id: string;
    Name: string;
  }
}

I am trying to access these interfaces from the main file. Here is what I attempted

ROOT/pages/main.ts

import { Model} from '../database/models'; //<-- this is where I face an issue

export class WorkerPostbidPage {

   myinbox:Model.Inbox; // <-- and I want to refer to it like this

   TestMethod() {
    this.myinbox = {
        title:"new message", 
        msg:"you have an alert"
     }
   }
}

However, when I manually paste the model content into the index.ts file, everything works smoothly

module Model {
  export interface Inbox {
    title: string;
    msg: string;
  }
  export interface User{
    Id: string;
    Name: string;
  }
}

export class WorkerPostbidPage {

   myinbox:Model.Inbox; // <-- and I want to refer to it like this

   TestMethod() {
    this.myinbox = {
        title:"new message", 
        msg:"you have an alert"
     }
   }
}

I believe there might be a mistake on my end, or perhaps I am overlooking some components

Answer №1

To ensure compatibility with the ES6 module, it is recommended to modify the model.ts file.

  export interface Inbox {
    title: string;
    msg: string;
  }
  export interface User{
    Id: string;
    Name: string;
  }

After making the necessary changes, you will be able to easily import them as shown below.

import { Inbox } from '../database/models';

Answer №2

To include an external module using this method is not possible. The external module will be integrated into the global scope, so it should be handled accordingly.

If you are working with amd modules, you can try something like the following:

declare module Model{
    interface Inbox{
        title: string,
        msg: string
    }
}

/// <amd-dependency path="../database/models"/>

export class WorkerPostbidPage {

    myinbox:Model.Inbox; // <-- This is how I want to reference it

    TestMethod() {
        this.myinbox = {
            title:"new message", 
            msg:"you have a notification"
        }
    }
}
