Trouble running scripts in parallel with PNPM v12

[daron81]

Anyone else having trouble running scripts in parallel with v12? It works fine in v11 for me with the same configuration.

With v12, it only runs the first command without the prefix.

My package.json config:

scripts: {
  "client:dev": "NODE_ENV=development node ./esbuild.ts",
  "server:dev": "wrangler dev --live-reload",
  "dev": "pnpm run '/.*:dev$/'"
}

Yes, I can reproduce this with pnpm 12.1.0.

The same config starts both scripts together on pnpm 11.24.0, but pnpm 12 waits for the first script to finish before starting the second. Since your dev processes keep running, server:dev never starts.

This looks like a pnpm 12 regression. The docs say regex-matched scripts should run concurrently unless --sequential is used:

https://pnpm.io/cli/run#running-multiple-scripts

For now, the safest fix is to stay on pnpm 11:

{
  "packageManager": "pnpm@11.24.0"
}

If you need pnpm 12, I tested this workaround successfully:

pnpm add -D concurrently@9

{
  "scripts": {
    "client:dev": "NODE_ENV=development node ./esbuild.ts",
    "server:dev": "wrangler dev --live-reload",
    "dev": "concurrently --kill-others-on-fail \"pnpm run client:dev\" \"pnpm run server:dev\""
  }
}

Both commands started together with this setup.

Thanks for confirming. I could not find an existing issue for this
