invalid typescript declaration

Describe the bug

The last line of dist/index.d.mts (and .d.ts) is:

export { vueJsxPluginCjs as 'module.exports', type FilterOptions, type Options, vueJsxPlugin as default };

I do not think this is valid -- and as it is a .d.mts file, there should also be no CJS interop in the file.

I'm also unclear why 'module.exports' is actually exported from index.mjs?

spotted in https://github.com/nuxt/ecosystem-ci/actions/runs/15928068917/job/44930076588#step:7:118

(Note - this is also true for plugin-vue, in the equivalent files.)

export { vueJsxPluginCjs as 'module.exports', type FilterOptions, type Options, vueJsxPlugin as default };

I do not think this is valid

It is a valid code. It is supported from ES2020+ and TS5.6+ (microsoft/TypeScript#58640).

-- and as it is a .d.mts file, there should also be no CJS interop in the file.
I'm also unclear why 'module.exports' is actually exported from index.mjs?

It is for require(ESM) (nodejs/node#54563). The value of module.exports export is the value when calling require for this module. For example, require('@vitejs/plugin-vue-jsx') returns vueJsxPluginCjs.

// vite.config.js
import vue from '@vitejs/plugin-vue';

export default {
plugins: [vue()],
}

I get an error:
Vue: This expression is not callable.
Type 'typeof import("node_modules/@vitejs/plugin-vue/dist/index")' has no call signatures.(2349)

Can u help me, please! I use vite@7.0.0 and @vitejs/plugin-vue@6.0.0

Thanks for the update. My mistake! I'm really not sure why the typecheck is erroring then; I'll investigate.

Example logs:

update: despite path in the log, it seems there was also a typescfript 5.5.2 installed in the repo, which was the issue.
