Issue with Opennext Cloudflare

[himanshu-ntml]

Thank you so much for all the effort you’ve put into this. I am currently trying to integrate with OpenNext Cloudflare, but I’m encountering an error in the stream.ts file due to a missing index.js file in the pg-cloudflare package.

I have tried looking into the package and found in export there is default and workerd. Somehow it not working on nextjs.

Here is the error:

I came here to report this issue. I patched it by manually moving this file from here to here.

  // Copy pg-cloudflare after building.
  const sourcePath = path.resolve(
    __dirname,
    '../../node_modules/.pnpm/pg@8.13.1_pg-native@3.0.1/node_modules/pg-cloudflare/dist/index.js',
  )
  const destinationPath = path.resolve(
    __dirname,
    '.next/standalone/node_modules/.pnpm/pg@8.13.1_pg-native@3.0.1/node_modules/pg-cloudflare/dist',
  )

Dependencies

• "@opennextjs/cloudflare": "https://pkg.pr.new/@opennextjs/cloudflare@2ab976f" (experimental branch, albeit this occurs in main)
• "next": "14.2.13",
• "pg": "8.13.1",

Chances are that this is specific to Next

I have tried looking into the package and found in export there is default and workerd. Somehow it not working on nextjs.

I think Next "traces" node files and that might explain why workerd files are missing.

I'll investigate and update here

Thank you so much @vicb
