Parse is undefined in Node JS Controller

I am trying to build a Node JS + Express web application using Parse.com. I have this in my server js:

var express = require('express'),
    app = express(),
    bodyParser = require('body-parser'),
    Parse = require('parse').Parse;
    projects = require('./controllers/projects');

// Parse fun
Parse.initialize('MY_APP_ID_HERE', 'MY_JS_KEY');

app.use(bodyParser.urlencoded({ extended: false }));

app.get('/projects',projects.index);
app.get('/projects/new',projects.new);

app.listen(9000);

Now in my projects controller:

module.exports.create = function(req,res){
    var projectObject = Parse.Object.extend("ProjectObject");
    var project = new projectObject();
    project.save(req.body).then(function(object) {
        res.redirect('/projects');
    });
};

module.exports.index = function(req,res){
    var projectObject = Parse.Object.extend("ProjectObject");
    var query = new Parse.Query(projectObject);
    query.limit(100);
    query.first({
        success: function(projects) {
            // Successfully retrieved the projects.
            res.json(projects);
        },
        error: function(error) {
            console.log("Error: " + error.code + " " + error.message);
        }
    });
};

This is the error I get:

ReferenceError: Parse is not defined at module.exports.create ([REST_OF_PATH_REMOVED]/app/controllers/projects.js:5:22) at Layer.handle [as handle_request] ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/layer.js:95:5) at next ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/route.js:131:13) at Route.dispatch ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/route.js:112:3) at Layer.handle [as handle_request] ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/layer.js:95:5) at [REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/index.js:277:22 at Function.process_params ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/index.js:330:12) at next ([REST_OF_PATH_REMOVED]/app/node_modules/express/lib/router/index.js:271:10) at [REST_OF_PATH_REMOVED]/app/node_modules/body-parser/lib/read.js:121:5 at done ([REST_OF_PATH_REMOVED]/app/node_modules/body-parser/node_modules/raw-body/index.js:233:14)

Simple answer would be to move

var Parse = require('parse').Parse;

and 

Parse.initialize('MY_APP_ID_HERE', 'MY_JS_KEY');

to your projects controller. They aren't necessary in your server.js file based on the code posted.

Parse is out of the fn's scope. You could either bring the declaration to your controller as recommended before or (although not a good practice) make Parse a global (just be careful by not overwriting the variable in other parts of your app)

app.js

...

global.Parse = require('parse').Parse;

...

controller.js

...

new Parse.query ...

...
