Error in `embroider-esbuild-resolver` with `rolldown-vite@latest`: `Not implemented` at Object.resolve

[johanrd]

I am not sure about the intended status of supporting Rolldown at the moment, but I'm posting an issue here for visibility in case someone else gets tempted to try out rolldown-vite as a "drop-in replacement".

Steps to reproduce

1. Clone this repo: https://github.com/johanrd/ember-vite (basically a fresh ember app + the vite codemod)
2. run pnpm start and see that everything runs as expected
3. Upgrade Vite to 7.0.0 in package json:

-    "vite": "^6.0.0"
+    "vite": "npm:rolldown-vite@latest"

4. run pnpm start again, and see the following error:

9:11:12 PM [vite] (client) error while updating dependencies:
Error: Build failed with 17 errors:

The error seems to come from vite/src/node/optimizer/pluginConverter.ts#L76-L78.

resolve() {
  throw new Error('Not implemented')
},

Context from @mansona on discord:

yea ideally we wouldn't need any of our strange esbuild hacks any more and can just use rollup apis to achieve what we need but like @NullVoxPopuli says, we're going to get "normal" vite working first 😂
