spawn-sync

spawn-sync

This used to be a polyfill for require('child_process').spawnSync but now all actively maintained node versions already support spawnSync, so this is just a stub that re-exports spawnSync.

Usage

You should remove this library from your dependencies and just do:

var spawnSync = require('child_process').spawnSync;

var result = spawnSync('node',
                       ['filename.js'],
                       {input: 'write this to stdin'});

if (result.status !== 0) {
  process.stderr.write(result.stderr);
  process.exit(result.status);
} else {
  process.stdout.write(result.stdout);
  process.stderr.write(result.stderr);
}

Similar packages

Other packages similar to spawn-sync

child_process

The child_process module is a core Node.js module that provides the ability to spawn child processes. It includes both asynchronous and synchronous methods (spawn, exec, execFile, fork, and their synchronous counterparts). Unlike spawn-sync, child_process is built into Node.js and does not require an additional package installation.

execa

Execa is a modern alternative to the child_process module. It provides a more user-friendly API for executing shell commands and scripts. Execa supports both asynchronous and synchronous execution, similar to spawn-sync, but offers additional features like improved error handling and promise support.

shelljs

ShellJS is a portable (Windows/Linux/macOS) implementation of Unix shell commands on Node.js. It provides a synchronous API for executing shell commands, similar to spawn-sync. ShellJS is designed to be more cross-platform and user-friendly, making it a good alternative for scripting tasks.
