I am beginning a new project that uses MEAN.JS (MongoDB, ExpressJS, AngularJS, Node.js). I use Apache as my webserver on my local Ubuntu VM. When I first read about using Express, I wondered how I would use Express and Apache together. Further confusion came when I learned that my host provider (webfaction uses Nginx to serve static files and Apache for PHP and other server-side technologies. So Node.js and Express will actually be running under Nginx. Because I wanted my development environment to be enulate production as much as possible, I decided to run Nginx and Apache together.
