Build process

Describe the bug

The build process fails to locate Qwik components when package.json is replaced by deno.jsonc.

Reproduction

https://github.com/quadratz/qwik-astro-issue-268-

Steps to reproduce

1. Make sure you have Deno installed
2. Clone this repository: https://github.com/quadratz/qwik-astro-issue-268-. (Notice that package.json has been replaced by deno.jsonc)
3. Run deno task build
4. Check the logs. You'll see could not read /package.json ... and a warning that the Qwik core bundle wasn't found.

Sorry for the delayed response, and thanks for the report 👍

From the logs, the build itself seems to complete successfully. The issue appears to come later during Qwik bundle detection:

Qwik core bundle not found, is Qwik actually used in this project?

What’s interesting is that the Qwik client build does seem to run correctly:

• q-manifest.json is generated
• Qwik bundles are emitted in dist/build

So this looks more like a Qwik-side detection/resolution issue rather than an actual build failure.

The repeated /package.json warnings may also be relevant here. Even when using deno.json(c), it’s still perfectly valid to keep a package.json alongside it, especially when working with tooling that still expects parts of the Node ecosystem.

So for now, you may want to try adding a minimal package.json to the project and see if that changes the behavior while we investigate further.

@siguici I'm working on a rewrite of the bundler that should be much more understandable and I think it should help when it comes to native deno support. It is rolldown 8 only.

We will end up needing an Astro fixture in here

Im getting the same issue Qwik core bundle not found, is Qwik actually used in this project?, ran build with node and bun and both seems to be giving the same result.

My setup:

https://stackblitz.com/~/github.com/NecroPrism4/rockypointnet-client

// @ts-check
import node from "@astrojs/node";
import qwik from "@qwik.dev/astro";
import tailwindcss from "@tailwindcss/vite";
import { defineConfig } from "astro/config";

// https://astro.build/config
export default defineConfig({
  output: "server",
  adapter: node({
    mode: "standalone",
  }),
  build: {
    serverEntry: "server.mjs",
    server: './server/index.mjs',
  },
  prefetch: true,
  integrations: [
    // https://astro.qwik.dev/docs
    // Note: If you are using the `@qwik.dev/astro` integration, you must also install `@qwik.dev/core` and add it to your dependencies.
    // See https://astro.qwik.dev/docs/upgrade for more details.
    qwik({ clientRouter: true }),
  ],

    plugins: [tailwindcss()],
