Package Exports

child-process-promise
child-process-promise/lib/ChildProcessPromise

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 (child-process-promise) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

exec

var exec = require('child-process-promise').exec;

exec('echo hello')
    .then(function (result) {
        var stdout = result.stdout;
        var stderr = result.stderr;
        console.log('stdout: ', stdout);
        console.log('stderr: ', stderr);
    })
    .catch(function (err) {
        console.error('ERROR: ', err);
    });

spawn

var spawn = require('child-process-promise').spawn;

var promise = spawn('echo', ['hello']);

var childProcess = promise.childProcess;

console.log('[spawn] childProcess.pid: ', childProcess.pid);
childProcess.stdout.on('data', function (data) {
    console.log('[spawn] stdout: ', data.toString());
});
childProcess.stderr.on('data', function (data) {
    console.log('[spawn] stderr: ', data.toString());
});

promise.then(function () {
        console.log('[spawn] done!');
    })
    .catch(function (err) {
        console.error('[spawn] ERROR: ', err);
    });

Options

capture

Type: Array
Default: []

Pass an additional capture option to buffer the result of stdout and/or stderr

var spawn = require('child-process-promise').spawn;

spawn('echo', ['hello'], { capture: [ 'stdout', 'stderr' ]})
    .then(function (result) {
        console.log('[spawn] stdout: ', result.stdout.toString());
    })
    .catch(function (err) {
        console.error('[spawn] stderr: ', err.stderr);
