spawncommand

spawncommand

extend require('child_process').spawn to set .promise property on the returned object. The promise will be fulfilled on process exit with a hash of code, stdout and stderr, where code is the exit code, stdout is all data the process wrote to stdout, and stderr is all data the process wrote to stderr. The promise will be rejected if process.on('error') fired.

npm i --save spawncommand

const spawnCommand = require('spawncommand')

const echo = spawnCommand('echo', ['hello world'])
echo
    .promise
    .then((res) => {
        console.error(res)
    })
    // { code: 0, stdout: 'hello world', stderr: '' }
    // echo is instance of ChildProcess)
