Let's you build your node-webkit apps for mac, win and linux via cli. It will download the prebuilt binaries for a newest version, unpacks it, creates a release folder, create the app.nw file for a specified directory and copys the app.nw file where it belongs.

npm install node-webkit-builder --save-dev

npm install node-webkit-builder -g

Yes, there is also a Grunt Plugin. For Gulp, just use the module :)

Usage: nwbuild [options] [path]

Options:
  -p, --platforms      Platforms to build, comma-sperated, can be: win,osx,linux32,linux64   [default: "osx,win"]
  -v, --version        The nw version, eg. 0.8.4                                             [default: "latest"]
  -r, --run            Runs node-webkit for the current plattform                            [default: false]  
  -o, --buildDir       The build folder                                                      [default: "./build"]
  -f, --forceDownload  Force download of node-webkit                                         [default: false]
  -c, --checkVersions  Disables checking versions, usefull when working offline              [default: true]
  --quite              Disables logging                                                      [default: false]

During development you can run node-webkit with nwbuild -r path/to/your/younwapp/

Or use the module:

var NwBuilder = require('node-webkit-builder');
var nw = new NwBuilder({
    files: './path/to/nwfiles/**/**', // use the glob format
    platforms: ['win','osx']
});

// Log stuff you want
nw.on('log',  console.log);

// Build retruns a promise
nw.build().then(function () {
   console.log('all done!');
}).catch(function (error) {
    console.error(error);
});

// And supports callbacks
nw.build(function(err) {
    if(err) console.log(err);
})
