Getting MaxListenersExceededWarning and "ELIFECYCLE Command failed" error

[ax-at]

When running below command in my "TurboRepo monorepo", which will run "turbowatch" in 8 packages.

pnpm exec turbowatch '**/turbowatch.ts'

I get below warning:

[turbowatch] running turbowatch without logging enabled; set ROARR_LOG=true to enable logging. Install @roarr/cli to pretty-print logs.
(node:78062) MaxListenersExceededWarning: Possible EventTarget memory leak detected. 11 abort listeners added to [AbortSignal]. Use events.setMaxListeners() to increase limit
(Use `node --trace-warnings ...` to show where the warning was created)

and further builds fail continuously for packages with below error:

ELIFECYCLE  Command failed.

But when I run with below command, which runs "turbowatch" only for 4 out of 8 packages:

pnpm exec turbowatch "./packages/logging/turbowatch.ts" "./packages/validators/turbowatch.ts" "./packages/trpc/turbowatch.ts" "./packages/schema/turbowatch.ts"

It seems to work fine.

System

• Node.js = v20.10.0
• PNPM = v8.15.6

Expected Behavior

TurboWatch should have been able to build all packages.

Current Behavior

The command fails with below warning and error:

[turbowatch] running turbowatch without logging enabled; set ROARR_LOG=true to enable logging. Install @roarr/cli to pretty-print logs.
(node:78062) MaxListenersExceededWarning: Possible EventTarget memory leak detected. 11 abort listeners added to [AbortSignal]. Use events.setMaxListeners() to increase limit
(Use `node --trace-warnings ...` to show where the warning was created)

Further builds fail continuously for packages with below error:

ELIFECYCLE  Command failed.

Possible Solution

May be using events.setMaxListeners() to increase the limit, but not sure how to do that.

Steps to Reproduce

Run turbowatch in a turborepo having more than 8 packages and each package having a turbowatch.ts as below:

import { defineConfig } from "turbowatch";

export default defineConfig({
  project: __dirname,
  triggers: [
    {
      expression: [
        "anyof",
        [
          "allof",
          ["dirname", "node_modules"],
          ["dirname", "dist"],
          ["anyof", ["match", "*.ts", "basename"]],
        ],
        [
          "allof",
          ["not", ["dirname", "node_modules"]],
          ["dirname", "src"],
          ["anyof", ["match", "*.ts", "basename"]],
        ],
      ],
      name: "build",
      onChange: async ({ spawn }) => {
        await spawn`pnpm run build`;
      },
      persistent: false,
    },
  ],
});
