It’s easy to use an Node.js module that you have installed in your PebbleKit JS-enabled application:

1. Install Browserify: 

   npm install -g browserify

2. Require your favorite NPM packages and use:

    var xml2js = require('xml2js');
   
    Pebble.addEventListener("ready", function (e) {
      var xml = "Hello xml2js!"
   
      xml2js.parseString(xml, function (err, result) {
        console.log(result.root);
      });
    });
   

3. Let Browserify compile all of your packages into a single file:

   browserify my-file.js -o pebble-js-app.js
