Vite Plus 0.2.4 `vp pack` fails generating dts with TypeScript 7.0.1-rc: No "exports" main defined

[Luzefiru]

Describe the bug

What I'm Doing

I am building a Vite Plus server package with vp pack and declaration generation enabled via pack.dts: true.

This was originally encountered while building a larger server app Dockerfile, but the linked repro removes the app-specific code. The repro fails with a single small TypeScript entrypoint as long as pack.dts: true and typescript@7.0.1-rc are used together.

Expected Behavior

I expect vp pack to build the server package successfully and emit declaration output.

Actual Behavior

vite-plus@0.2.4 fails during declaration generation when the project uses typescript@7.0.1-rc. The failure happens in rolldown-plugin-dts:generate with:

Error [PLUGIN_ERROR]: No "exports" main defined in .../node_modules/typescript/package.json

Controls checked:

• pack.dts: true + typescript@7.0.1-rc fails.
• pack.dts: false + typescript@7.0.1-rc passes.
• pack.dts: true + typescript@6.0.3 passes.

Reproduction

https://github.com/Luzefiru/repro-ts-7-vp-pack-build-error

Steps to reproduce

vp install
vp run -v --filter server build

The Docker path also reproduces the same issue:

docker build -f apps/server/Dockerfile .

In Docker, the failing path is:

Direct package-root resolution also fails with TypeScript 7:


node -e "try{console.log(require.resolve('typescript'))}catch(e){console.error(e.code); console.error(e.message); process.exit(1)}"


Output:


ERR_PACKAGE_PATH_NOT_EXPORTED
No "exports" main defined in .../node_modules/typescript/package.json


The observed `typescript@7.0.1-rc` package exports include subpaths such as `./unstable/sync`, `./unstable/async`, and `./package.json`, but no `"."` export.

Validations

• Read the Contributing Guidelines.
• Check that there isn't already an issue for the same bug.
• Confirm this is a Vite+ issue and not an upstream issue (Vite, Vitest, tsdown, Rolldown, or Oxc).
• The provided reproduction is a minimal reproducible example.

Thanks for the detailed reproduction. This appears to be another manifestation of the TypeScript 7 support work tracked in #2148.

The failure should be addressed by updating Vite+'s bundled tsdown to a version that supports TypeScript 7 and by declaring TypeScript 7 support in Vite+ itself.

#2155 covers the tsdown 0.22.5 upgrade and the TypeScript 7 peer range, while #2147 covers the corresponding Vite+ peer updates.

Just so you know, this bug caused by rolldown-plugin-dts.
Here's the flow:

1. tsdown loads pack options.
2. When dts option is true, it loads rolldown-plugin-dts (tsdown source code)
3. rolldown-plugin-dts imports typescript (relevant part of rolldown-plugin-dts)
4. rolldown-plugin-dts's package.json allows 7.0.x of typescript as typescript:^7.0.0 but typeScript@7.x.x does not export api (rolldown-plugin-dts's package.json).

if dts option is false, tsdown do not load rolldown-plugin-dts.
if the typescript version is not 7.0.x, typescript export that api.

So this bug occurs when typescript is 7.0.x and dts is true.
