Fixes #157 on main (1.x). The fix for next is in a separate PR.

In a workspace, a Solid package declared only in the workspace root's package.json is now inlined. Before, Vitest left it external, Node loaded its raw .jsx files, and tests failed with Unknown file extension ".jsx".

Cause

• vitefu's crawlFrameworkPkgs only reads the package.json at the Vite root.
• npm and yarn workspaces hoist root dependencies, so a project can import packages its own package.json does not list.
• Those packages never reached ssr.noExternal, which Vitest 4 and later uses to build its inline list.

Changes

• When searchForWorkspaceRoot(root) differs from the project root, the plugin also crawls the workspace root's package.json.
• Only the ssr.noExternal entries from that crawl are merged. optimizeDeps.include entries must resolve from the project root, so they are not added.
• The change also applies to dev SSR and builds. Inlining a package that is never imported has no effect.

Testing

• Reproduced with an npm workspace: a root vitest.config.ts with projects: ['modules/*'], and @solidjs/router declared only in the root package.json.
  • Vitest 5.0.5 failed with TypeError: Unknown file extension ".jsx" for .../@solidjs/router/dist/routers/...jsx.
  • With the fix, the test passes.
• Added examples/vite-6/tests/workspace-root.mjs, run as part of the vite-6 test script. It resolves the config for a temporary workspace and fails without the fix.
• tsc --noEmit passes. The vite-6 browser suite was not run locally, because Playwright's browser is not installed.
