Replacement for vite-plugin-dts with rollupTypes: true for vite 8 beta/vite-rolldown?

[wesleymatosdev]

Is there a replacement to bundle all d.ts into one for vite-rolldown or for vite 8 beta?

I'm using https://www.npmjs.com/package/vite-plugin-dts but I couldn't found a replacement for rolldown to migrate to it.

vite-plugin-dts takes an eternity to build here, to the point I'm disabling rollupTypes altogether, but still, some stuff on my environment depends on the bundles.

Is there a faster alternative to vite-plugin-dts?

You probably want https://github.com/rolldown/tsdown, vite is incapable of emitting type definitions.

For Vite 8/rolldown migration, a practical path is:

1. Keep declaration emit in tsc (fast + stable), and let Vite/rolldown handle JS bundling.
2. If you need single-file .d.ts, run API Extractor as a post-step.

Example pipeline:

{
  "build": "vite build && tsc -p tsconfig.build.json --emitDeclarationOnly",
  "types:bundle": "api-extractor run --local"
}

This avoids vite-plugin-dts bottlenecks while preserving bundled type output when needed.

Also worth checking:

• skipLibCheck only for app projects (not libraries)
• split tsconfig.build.json with narrow include
• disable source maps for type emit stage

In short: JS bundle with Vite, types with tsc/API Extractor is currently the most predictable and usually faster path.

I haven't tested but according to my research I believe that's the right answer. Thanks for the detailed step-by-step, appreciate it @karmahacker.

https://github.com/sxzz/rolldown-plugin-dts might also be an option, it's what tsdown uses to generate dts, not sure if it has a equivalent to rollupTypes. I would definitely try to avoid api-extractor, it's bloated.

I tried this one, but had issues finding an equivalent to rollupTypes. I think api-extractor is the best option tbh. all tools I found that support type bundling use api-extractor underlying, some way or another.
