CloudflareSocket is not a constructor in [email protected]

[astanciu]

I'm using pg in a cloudflare worker and this worker is using vite, using the cloudflare vite plugin.

The new pg-cloudflare package on version 1.2.6 is causing this error:

Unhandled error: TypeError: CloudflareSocket is not a constructor

I dug around trying to figure it out, but was unable to. I saw in the pg-cloudflare readme references to things related to this.. I updated my worker's vite.config file with

  build: {
    rollupOptions: {
      external: ["cloudflare:sockets"],
    },
  },
resolve: {
    conditions: ["cloudflare"],
}

but this didn't help. Reverting back to 1.2.5 fixed me.

Am I missing some new required config or is there a bug somewhere?

This is because vite-plugin-cloudflare hardcodes export conditions and is using "workerd" instead of "cloudflare" https://github.com/cloudflare/workers-sdk/blob/main/packages/vite-plugin-cloudflare/src/cloudflare-environment.ts#L128

any idea how to fix it temporary for pg? i downgraded "pg": "8.15.6" and "wrangler": "4.18.0" but anyway have this error :hiddenpain: i dont have vite-plugin-cloudflare in node_modules at all. but still have the same error

looks like this should fix it:

"pg": "8.15.6",
"pg-cloudflare": "1.2.5" // fix optional dep in pg

I fixed by patching pg-cloudflare like this

Not clear on how to implement this fix? could you provide a clearer solution?

[TrySound]

Using patch-package for npm

Pnpm has builtin command for this

@TrySound i am having this exact issue as well, do you have a suggestion that does not involve patching? Downgrading to a specific version maybe?

[korywka]

@hyusetiawan you can try fix from my comment: https://github.com/brianc/node-postgres/issues/3493#issuecomment-2987974927 it helped me at least :)
