Describe the Bug

I'm not able to specify a Vue entry point like I could in Astro 2.x and 3.x, despite following the docs.

What's the expected result?

I expected my app to load up properly.

This was a regression introduced in #8794! I unfortunately didn't catch it before the release went out.

I've opened #9333 with a fix. It's unlikely to get merged immediately, but you can pin "@astrojs/vue": "4.0.0" in your package.json file in the meantime.

I appreciate your prompt help with this—as always! 🙌

@ffxsam Is it working for you now?

I am using astroV4.0.3 with @astrojs/vueV4.0.2 and vuejsV3.3.11 and still get the warning [@astrojs/vue] Unable to resolve appEntrypoint /src/vue-main. Does the file exist?

I configured the appEntrypoint like this:
/astro.config.mjs

,
integrations: [
  ...,
  vue({ appEntrypoint: '/src/vue-main' })
]

/src/vue-main.js

export default (app) => {
  // ...
}

@szv I believe the bug lies in @astrojs/vue, not astro. And I haven't seen an update come through for that yet, so you'll have to pin @astrojs/vue at 4.0.0 for now.

@ffxsam Thank you for your answer. But for me it doesn't work with 4.0.0 eighter 😅
I think I will have to wait for future versions.

Hi @natemoo-re , has there been any progress on this issue? I continue to encounter the same problem. After updating @astrojs/vue to version 4.0.0, the build completes without issues. However, as soon as I open the webpage, the error returns.

Error message:
ReferenceError: Cannot access '_export_sfc' before initialization

I was able to eliminate the error, which was related to the import from "astro/zod". By switching them back to "astro:content", the error disappeared. This is peculiar because there's a warning in the console that says:

"astro:content is only supported when running server-side. Using it in the browser will result in bloated bundles and slower page loading times. It will not be supported in the future."
