@formatjs/unplugin/vite

Describe the bug

React Router splits routes that export clientAction/clientLoader into virtual chunk modules (e.g. route.tsx?route-chunk=main). The formatjs unplugin's transformInclude filter rejects these IDs because they don’t end in .tsx, so defineMessage calls in those chunks never get their id injected.

To Reproduce

• Have a project that uses both React Router and FormatJS

• Have a vite config that includes both formatjs and reactRouter plugins

• Don’t write ids in the application code, rely on FormatJS to insert these

• Have a route that exports a clientLoader/clientAction

• Create a production build (via the dev server, everything works as expected)

  plugins: [
    formatjs({
      idInterpolationPattern,
      removeDefaultMessage: true,
    }),
    reactRouter()
  ]
  

Expected behavior

FormatJS transform works regardless of React Router setup
