Cannot find module 'ember-simple-auth/mixins/application-route-mixin'

[theseyi]

I have a tsconfig.json file similar to the following, but

{
  "compilerOptions": {
    "target": "ES6",
    "allowJs": true,
    "moduleResolution": "node",
    "noEmitOnError": true,
    "noEmit": true,
    "baseUrl": ".",
    "sourceMap": true,
    "paths": {
      "ember-simple-auth/mixins/application-route-mixin": [
        "node_modules/ember-simple-auth/addon/mixins/application-route-mixin"
      ]
    }
  },
  "include": [
    "app/**/*"
  ]
}

and in routes/application.ts:

import Ember from 'ember';
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';

However, when i run ember serve, I get the following error in the build process:

/my-app/routes/application.ts(7,35): Cannot find module 'ember-simple-auth/mixins/application-route-mixin'.
/my-app/routes/application.ts(7,35): Cannot find module 'ember-simple-auth/mixins/application-route-mixin'.

How do I get ember-cli-typescript to correctly pick up this file?

• I should note that manually running tsc works as expected and
• I have stopped ember serve and restarted after making the edits

Resolved this with ambient module declaration.

Thanks, @theseyi! Next time I get ten minutes, I'll try to add this to the README.

Can you share what your actual module declaration looked like and where you put it? That'll help me (a) document it clearly for users today and (b) think about how to recommend people start building/submitting typings for other libraries as we go.

Hey @chriskrycho, sure. In .d.ts file.

// typings/ember-simple-auth/mixins/application-route-mixin.d.ts
declare module '*';

and included a reference path directive in the file where I had the import

import Ember from 'ember';
/// <reference path="../typings/ember-simple-auth/mixins/application-route-mixin.d.ts" /> 
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';
