Demonstrating authentication by verifying a token using Express route middleware.

• node, npm, express and mongoose

1. Clone the repo
2. Install dependencies: npm install
3. Change SECRET in config.js
4. Add your own MongoDB database to config.js
5. Start the server: node server.js
6. Create sample user by visiting: http://localhost:3000/setup

Once everything is set up, we can begin to use our app by creating and verifying tokens.

Send a POST request to http://localhost:3000/api/authenticate.

You can also send the token as a URL parameter: http://localhost:3000/api/users?token=YOUR_TOKEN_HERE
