@counterscale/server#build fails: EPIPE write error

[shazow]

Heya, finally got around to trying counterscale (sorry it took so long 😅), followed the instructions on the README (using the latest main branch) but I'm getting an error on the npx turbo deploy step (note I'm running on NixOS, but I don't think it should matter).

Sounds like a miniflare socket write error maybe? I'm not familiar enough with the inner workings yet to debug.

Any idea what might cause this? Full output below:

$ npx turbo deploy

@shazow 👋

Could you try the following and let me know what you get?

1. Get the Miniflare version you have installed, it looks different than mine (3.20241218.0):

cat /home/shazow/local/src/github.com/benvinegar/counterscale/node_modules/miniflare/package.json | grep version

2. Try running the server build command outside of Turbo (just in case):

npm run build --workspace=@counterscale/server

[shazow]

$ cat /home/shazow/local/src/github.com/benvinegar/counterscale/node_modules/miniflare/package.json | grep version
  "version": "3.20241218.0",

$ npm run build --workspace=@counterscale/server

> @counterscale/[email protected] build
> react-router build

Looks like it's choking trying to write to stdin:

https://github.com/cloudflare/workers-sdk/blob/main/packages/miniflare/src/runtime/index.ts#L154

		// 3. Write config, and wait for writing to finish
		runtimeProcess.stdin.write(configBuffer);
		runtimeProcess.stdin.end();
		await once(runtimeProcess.stdin, "finish");

I'm feeling like this has something to do with your build environment.

Seems like this person on Stack Overflow may have hit the same issue?

Edit: might be this cloudflare/workers-sdk/issues/3262

[shazow]

Ah interesting, looks like the nixpkgs version of wrangler does have additional workarounds, I'll see if I can replicate.

[shazow]

Argh, I'm on a bandwidth-constrained internet for the next week+ so I won't be able to download the full 2gb toolchain to reproduce the environment in the flake, so going to put it off for now. :)

[shazow]

@benvinegar Btw would it make sense to have a pre-built version of this that can be deployed easily? Or is that ideologically opposing? :)

[benvinegar]

@shazow 100% – it's actually already on this branch if you want to give it a try: #153

On that branch, the @counterscale/server package is built and published to npm and pulled down by the CLI.
