Package.json subpath imports do not work

[jakst]

When updating solid-start from v0.6.0 to v0.7 I started getting this crash in the dev server for any page load. Not sure which underlying vinxi package is causing it though.

[h3] [unhandled] H3Error: Missing "#vinxi/handler/ssr" specifier in "app" package
    at e (file://./node_modules/.pnpm/vite@5.1.5/node_modules/vite/dist/node/chunks/dep-G-px366b.js:47398:25)

Turns out it's caused by specifying subpath imports in package.json. Even an empty object will trigger.

package.json

{
  // ...
  "imports": {}
  // ...
}

Here's a stackblitz reproduction https://stackblitz.com/edit/solidjs-solid-start-wtwqtu

what are "imports", i apologize i'm not familiar, so if you could explain what it does and why u need it, that would help in getting some direction

It's like tsconfig paths, but standardized. TS started supporting it for auto imports in v5.4, so it just recently became usable for real. This avoids a lot of tooling having to read the tsconfig file just to resolve paths.

does vite support it?

[jakst]

Yes. https://github.com/vitejs/vite/issues/7385 https://github.com/vitejs/vite/pull/7770

Not completely sure which Vinxi version is causing the issues, but they started when upgrading from solid-start v0.6.0 to v0.7. Definitely worked with Vite before that.

Ahh okay lemme see what's wrong. If vite supports it we should be able to get it working too

This is still an issue as of 0.3.11
