Research direction

Start with the Qwik Runtime bundle detection and resolution logic, then reproduce the problem with the linked Deno project by running deno task build. Done means a Deno project using deno.json(c) without a root package.json detects its generated Qwik assets without the bundle-not-found or package-name errors.

Description

bug missing info V2
Which component is affected?

Qwik Runtime

Describe the bug

Related issue:

In a Deno project using deno.json(c) without a root package.json, the build completes successfully and Qwik assets are generated correctly (q-manifest.json, dist/build/q-*.js, etc.).

However, Qwik later reports:

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

The logs also repeatedly show:

could not read /package.json to determine package name

This suggests that part of the current bundle detection / resolution logic may still implicitly rely on a Node-style project layout with a root package.json.

Reproduction

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

Steps to reproduce
  1. Make sure you have Deno installed
  2. Clone this repository. (Notice that package.json has been replaced by deno.jsonc)
  3. Run deno task build
  4. Check the logs.
