Node JS Authentication using JWT

• Install the following modules:

  $ npm init
  $ npm install express --save
  $ npm install mongoose --save
  $ npm install morgan --save
  $ npm install body-parser --save
  $ npm install jsonwebtoken --save

• File structure would be like :
  • package.json
  • config.js
  • server.js
  • models/user.js
• First comment off the route middleware code
• Then navigate to this route(/api/setup) in postman, then run this route(/api/authenticate) and copy the token.
• Uncomment the route middleware code.
• Now try to access other routes that is defined.

This is very simple app just to demonstarte how token works in nodejs.
