@henryqw/pi-process

Run one argv-only child process. Limit UTF-8 output and execution time. Cancel the process when necessary.

Install

npm install @henryqw/pi-process

Use

import { spawnBounded } from "@henryqw/pi-process";

const result = await spawnBounded("git", ["status"], { cwd: process.cwd() });
if (result.code !== 0 || result.killed) throw new Error(result.stderr);

spawnBounded accepts an optional UTF-8 string on stdin. It strictly decodes stdout and stderr. The default timeout is 30 seconds. Pass timeoutMs: null for a process without an elapsed-time limit. Cancellation and output limits still apply.

Each output stream has a 64 KiB limit. Set stdoutTailBytes to keep only the end of stdout instead of applying the stdout limit. The retained text has complete UTF-8 characters.

On POSIX systems, cancellation and timeout terminate the child process group. Invalid command, argument, and working-directory values cause failure before a child starts.
