Package Exports

spawn-sync

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (spawn-sync) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

spawn-sync

Polyfill for child_process.spawnSync.

On iojs and node >= 0.12 it will just export the built in child_process.spawnSync. On platforms that support compiling native modules it uses the execSync module to get true synchronous execution. If native compilation is not supported it falls back to waiting for an output file to exist in a tight loop. In this way it gains excellent cross platform support, but don't expect it to be efficient on all platforms.

Installation

npm install spawn-sync

Usage

var spawnSync = require('spawn-sync');

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

// Note, status code will always equal 0 if using busy waiting fallback
if (result.status !== 0) {
  process.stderr.write(result.stderr);
  process.exit(result.status);
} else {
  process.stdout.write(result.stdout);
  process.stderr.write(result.stderr);
}
