Imagine I have OrderComponent and CustomerComponent that represent two screens.

In the web version you can create a new customer while in the order screen by launching the customer component inside a popup. So OrderComponent references CustomerComponent directly in the template. So I have to keep both in the same FeaturesModule for this to work.

On the other hand in the Nativescript mobile version, there is no such capability and so the two components/screens are completely independent, so I would like to put them in 2 separate modules: OrderModule, and CustomerModule. And lazy load them so the app launches faster.

In my real application of course it's not just 2 components but several dozens so the mobile app performance is a more pressing issue.

When I try to add a module file with the tns extension like this: order.module.tns.ts, without the corresponding web file, it seems as if the NativeScript bundler is not picking it up, I get the following error:

ERROR: C:\...\src\app\features\orders\orders.module.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
 at AngularCompilerPlugin.getCompiledFile (C:\Users\...\node_modules\@ngtools\webpack\src\angular_compiler_plugin.js:753:23)
    at plugin.done.then (C:\Users\...\node_modules\@ngtools\webpack\src\loader.js:41:31)

 @ ../node_modules/@angular/core/fesm5/core.js
 @ ../node_modules/nativescript-angular/platform.js
 @ ./main.ns.ts

But according to the docs, all I have to do to make a nativescript specific component is add it with the tns extension. Is there another step to make this work for module files?? Help is appreciated

Update Here is my tsconfig.tns.json

{
  "extends": "./tsconfig.json",
  "compilerOptions": {
    "module": "es2015",
    "moduleResolution": "node",
    "baseUrl": "./",
    "paths": {
      "~/*": [
          "src/*"
      ],
      "*": [

          "./node_modules/*"

  • Can you show us your tsconfig and webpack.config? – Manoj Jan 04 '19 at 07:15
  • @Manoj I included tsconfig.tns.json. I did not find any file called webpack.config. My project is the default core sharing project generated with this command: ng new -c=@nativescript/schematics project-name --shared – Ahmad Akra Jan 04 '19 at 07:23
  • @Manoj my bad. webpack.config.js was not showing in VS Code, but I found it in file explorer. I included it in my question as well – Ahmad Akra Jan 04 '19 at 07:41
  • Are you sure the `nsext` in your `nsconfig.json` reads `".tns"`? – Manoj Jan 04 '19 at 13:57
