Missing definition files in dist folder

[frank-weindel]

Describe the bug

I have some manual d.ts definition files that import some other manual d.ts files that do not have corresponding .js code files. Specifically in my reproduction below I have these files in my src directory:

src
├── types   <------ NONE OF THE FILES IN THIS DIRECTORY ARE COPIED TO `dist`
│   ├── README.md
│   ├── lng.components.namespace.d.ts
│   ├── lng.d.ts
│   ├── lng.shaders.c2d.namespace.d.ts
│   ├── lng.shaders.namespace.d.ts
│   ├── lng.textures.namespace.d.ts
│   ├── lng.tools.namespace.d.ts
│   └── lng.types.namespace.d.ts
├── internalTypes.d.mts <------ ALSO MISSING
├── commonTypes.d.mts <------ ALSO MISSING
├── lightning.d.mts
├── lightning.mjs
└── ...

src/lightning.d.mts

// ...
import * as lng from "./types/lng"; // <----- This `d.ts` file and the files it depends on are not copied over to `dist`

/**
 * This seeming nonsense helps us export all the types with the same names/structure as
 * their runtime counterparts.
 */
declare namespace lng_ {
  export import lng_ = lng;
}

export default lng_.lng_;

src/types/lng.d.ts

// ...
import * as shaders from './lng.shaders.namespace';
import * as textures from './lng.textures.namespace';
import * as components from './lng.components.namespace';
import * as tools from './lng.tools.namespace';
import * as types from './lng.types.namespace';
// ^ ----- None of these are copied over either

export {
  Application,
  Component,
  Base,
  Utils,
  StageUtils,
  Element,
  Tools,
  Stage,
  ElementCore,
  ElementTexturizer,
  Texture,
  EventEmitter,
  shaders,
  textures,
  components,
  tools
};

// `types` has to be exported as type so TS/IDEs don't allow you access it from runtime context
export type {
  types
};

As mentioned in the comments of the code above, none of the files in the src/types directory are copied over to dist. Which causes TypeScript to throw errors because of missing dependencies in any application that uses this library as a dependency.

dist
├── index.d.ts <--- Definition file copied over by vite-plugin-dts
├── ...
└── src <--- Definition files copied over by vite-plugin-dts
    ├── EventEmitter.d.mts
    ├── EventEmitter.d.mts.map
    ├── animation
    ├── application
    ├── components
    ├── flex
    ├── lightning.d.mts
    ├── lightning.d.mts.map
    ├── platforms
    ├── renderer
    ├── textures
    ├── tools
    └── tree
                ^----------- Note how the `types` directory is completely missing.
                             As well as `internalTypes.d.mts`/`commonTypes.d.mts`

I believe in 2174868 (prompted by #178) is where you added the copying of manual .d.ts files.

Thanks!

I also observed similar issue. may be that one is also connected to this issue.

Here is how it looks on my end:

config on vite.config

  plugins: [
    react(),
    dts({
      insertTypesEntry: false
    })
  ],

Files generated after first run (no previous build present):

Files generated after second run (previous build present):

For me downgrading to "vite-plugin-dts": "1.7.3", resolved the issue.

Fixed in 3.0.1. You need to specify copyDtsFiles: true.
