Package Exports

buffered-spawn

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

Readme

buffered-spawn

Buffered child_process#spawn.

Installation

$ npm install buffered-spawn

Why

Easy to use
Uses cross-spawn by default, which fixes windows issues
Supports callback & promise style

Usage

In terms of arguments, they are equal to node's spawn.

const bufferedSpawn = require('buffered-spawn');

// Callback style
bufferedSpawn('git', ['clone', 'git@github.com/bower/bower'], { cwd: '.' }, (err, stdout, stderr) => {
    if (err) {
        // Both stdout and stderr are also set on the error object
        return console.error(`Command failed with error code of #${err.status}`);
    }

    console.log(stdout);
    console.log(stderr);
});

// ...or Promise style
bufferedSpawn('git', ['clone', 'git@github.com/bower/bower'], { cwd: '.' })
.then((output) => {
    console.log(output.stdout);
    console.log(output.stderr);
}, (err) => {
    // Both stdout and stderr are also set on the error object
    console.error(`Command failed with error code of #${err.status}`);
});

The actual child process is available if necessary:

const buffspawn('buffered-spawn');

// Callback style
const cp = buffspawn('git', ['clone', 'git@github.com/bower/bower'], () => {}};

// ...or Promise style
const promise = buffspawn('git', ['clone', 'git@github.com/bower/bower']);
const cp = promise.cp;

As said before, buffered-spawn uses cross-spawn to actually spawn the process. If you are having trouble running Windows such as wmic which has its own arguments parser, you may disable like so:

const cp = buffspawn('wmic', [
    'logicaldisk', 'where', 'DeviceID="Z:"',
    'get' 'freeSpace,size'
], { crossSpawn: false }, () => {}};
