Using a node module in my Angularjs app

The simplest starting point would be to use Browserify to build a standalone bundle that uses a global of your choice.

To do this, you could create a JS file that requires the node module(s) you want to use. You could create a file named bundle-index.js with this content:

exports.xero = require('node-xero');

You could then run this command to build a standalone module:

browserify --standalone the_global bundle-index.js > bundle.js

Where the_global is a name you find appropriate for the global object that will contain the exports. With the bundle.js file included in a script element, you would be able use it like this:

var privateApp = new window.the_global.xero.PrivateApplication({ ... });

Doing things this way would involve the least amount of disruption to your current project. And if you are only needing to use Browserify to require third party libraries that don't change frequently, you could start with a simple manual process for building the standalone bundle.

Note that you can export other required modules by adding additional exports to bundle.js:

exports.xero = require('node-xero');
exports.someOtherModule = require('some-other-module');

(function(){

   var xero = require('node-xero');

    angular
        .module('app')
        .factory('myFactory', myFactory);

    function myFactory(){

        var helper = {
            myMethod: myMethod,
        };

        return helper;

        function myMethod(){
            xero.doStuff();
        }

    }
})();
