[Typescript] Typings files not concatenated?

[thekevinscott]

Hi there,

It looks like when using Typescript, typings files are being emitted that match the files on disk, instead of being concatenated to a single file. I've set up a repo here demonstrating.

So, for instance, you've got a src directory with:

- /src
  - index.ts
  - foo.ts

This creates a dist directory with:

- /dist
  - foo.d.ts
  - index.d.ts
  - index.js
  - index.js.map
  - index.mjs
  - index.mjs.map
  - index.umd.js
  - index.umd.js.map

My understanding with the Typescript compiler is that, when emitting to a single file, typings should be emitted to a single d.ts file as well. But they are not here.

Well, that's not something we configured

I know it happens but doesn't cause any problems for me

Is there a way to override the default tsconfig? I tried adding an outFile in the tsconfig but that introduced other errors.

If you don't get any problems because of it I'd say just leave it be

This actually generates problems when having typescript files across multiple directories.

For instance:

- /src
  - /cars
      - cars.ts
  - index.ts

Microbundle will then generate:

- /dist
  - /cars
      - cars.d.ts
  - index.d.ts
  - index.js
  - ...

This simply won't work because the whole js code is bundled into the index.js but the definitions are nested into directories.
So doing import { Car } from 'my-lib' won't have types because they are actually inside my-lib/cars.
And doing import { Car } from 'my-lib/cars' won't get to the js code
