In this post we will write a very simple RESTful API for user registration and login .We will be using mongodb official mongo-go-driver for populating data.We will use jwt-go to decode, verify and generate Authentication tokens.

In this post we will write following end points :

  1. /register POST ( New user registration)
  2. /login POST (Existing user can login )
  3. /profile GET (To get user details)

I am assuming that you have already installed go in your system and set the go path. If not then you can follow and install go on your system.

Project setup

  1. Create a new folder go-login
