“dist-custom-elements-bundle” only produces type definitions when there’s also a “dist” output type

[lxg]

Stencil version:

@stencil/core@1.14.0

(partially reproducible with 1.15.0-2 as well, see below)

I'm submitting a:
[x ] bug report
[ ] feature request
[ ] support request

Current behavior:

The output target dist-custom-elements-bundle only produces type definitions when there’s also a dist output type.

For example, I have the following stencil config:

import { Config } from '@stencil/core';
import { sass } from "@stencil/sass";

export const config: Config = {
  namespace: 'elements',
  outputTargets: [
    {
      type: 'www',
      dir : 'dist/dev',
      serviceWorker: null
    },
    {
      type: 'dist',
      dir : 'dist/legacy'
    },
    {
      type: 'dist-custom-elements-bundle',
      dir : 'dist/prod'
    }
  ],
  plugins: [
    sass()
  ]
};

When I disable the type: dist entry and run stencil build, I only get a dist/prod/index.js file.

When I publish this as an NPM package and try to use it in another project, I get a “Cannot find module … or its corresponding type declarations.” error. (Note: This error does not appear in v1.15.0-2; however, the rest of this issue still exists there.)

With the type: dist entry enabled, I do get a dist/prod/index.d.ts file, but it references the types generated in the dist/legacy target.

Expected behavior:

The dist-custom-elements-bundle target should produce a self-contained package, without the dependency on another build target.

Steps to reproduce:

(See example config above)

Other information:

By the way, the info on publishing packages is empty/broken: https://stenciljs.com/docs/publishing

A similar problem was fixed with #2402... maybe it is related? There's an internal dist-types output target and dist-custom-elements-bundle should also enable it but I assume it doesn't.

@simonhaenisch Not sure if it is related; could well be. But if that bug is already fixed, would that be a regression? Or does it still happen because my build is happening in “prod mode”?

On a related note, is there documentation on how I can install Stencil in “source mode”, so I can poke around in the code and maybe even come up with a fix?
