@henryqw/pi-process
Run one argv-only child process with bounded UTF-8 output, cancellation, and a timeout.
Install
npm install @henryqw/pi-processUse
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, and each output stream is limited to 64 KiB. Set stdoutTailBytes to retain a UTF-8-safe tail instead of applying the stdout limit.
On POSIX systems, cancellation and timeout terminate the child process group. Invalid command, argument, and working-directory values fail before a child starts.
