TypeScript ES6 import module File is not a module error

0 votes

I am using TypeScript 1.6 with ES6 modules syntax.

My files are:

test.ts:

module App {
  export class SomeClass {
    getName(): string {
      return 'name';
    }
  }
}

main.ts:

import App from './test';

var a = new App.SomeClass();

When I am trying to compile the main.ts file I get this error:

Error TS2306: File 'test.ts' is not a module.

How can I accomplish that?

We need the export, as a part of the test.js file. Adjust the content of it like this:

// test.js - exporting es6
export module App {
  export class SomeClass {
    getName(): string {
      return 'name';
    }
  }
  export class OtherClass {
    getName(): string {
      return 'name';
    }
  }
}

And now we can import it with these three ways:

import * as app1 from "./test";
import app2 = require("./test");
import {App} from "./test";

And we can consume imported stuff like this:

var a1: app1.App.SomeClass  = new app1.App.SomeClass();
var a2: app1.App.OtherClass = new app1.App.OtherClass();

var b1: app2.App.SomeClass  = new app2.App.SomeClass();
var b2: app2.App.OtherClass = new app2.App.OtherClass();

var c1: App.SomeClass  = new App.SomeClass();
var c2: App.OtherClass = new App.OtherClass();

and call the method to see it in action:

console.log(a1.getName())
console.log(a2.getName())
console.log(b1.getName())
console.log(b2.getName())
console.log(c1.getName())
console.log(c2.getName())
