Vue 3 + Volar: TS2307 “Cannot find module '*.vue'” when plugin is enabled

[lfazliev]

Environment

typescript                 5.8.3
typescript-plugin-css-modules 5.1.0
vue                        3.5.17
@vitejs/plugin-vue         6.0.0
VS Code                    1.102.1
Volar extension            v3.0.3 (built-in)
OS                         Windows 11

tsconfig (reduced)

{
  "extends": "@vue/tsconfig/tsconfig.dom.json",
  "compilerOptions": {
    "plugins": [{ "name": "typescript-plugin-css-modules" }]
  },
  "include": ["src/**/*", "src/**/*.vue"]
}

Steps to reproduce

1. npm create vue@latest (or any fresh Vue 3 + TS + Volar project)
2. npm i -D typescript-plugin-css-modules
3. Add the plugin to compilerOptions.plugins as above
4. Open VS Code → wait until TS Server restarts

Expected
• SFC imports still resolve, e.g.

import Home from './Home.vue'

type checks without errors, while CSS-module types are available.

Actual
• Types for style modules works correctly
but
• Every import X from './*.vue' shows TS2307: Cannot find module ‘…’

If I remove the plugin line, the errors disappear immediately.

Minimal repro repo

Additional context / hypothesis
It looks as if the plugin overrides resolveModuleNames and doesn’t fall back to the default resolver for unknown extensions (.vue). Volar relies on .vue being resolvable, so type acquisition breaks.

Is there a way to let the plugin coexist with the default resolver (or to whitelist .vue)?
Happy to test nightly builds or provide more logs if needed.

Thanks! 🙏
