golang-auth-with-custom-router

My implementation of authentication from scratch without using any library and custom routing.

This repo is pretty easy to understand.

router.go

• This file contains implementation of basic router struct which can be used to register rest api with different methods. It is basic but more features than vanilla golang mux.
• Not much to do here. You can see the implementation if you want.

utils.go

• This file contains all the functions which were used for various purposes.
• There is a function to create users. Here we are using a redis database.
• There is a function generateToken() which generates a custom JWT for the specific user, without using any external library. It uses golang's in-built crypto package.
• Then there is a custom function called hashPassword to generate password hash for user safety.

main.go

• All the routes are registered here.
• Database connections are also initialized here.
• It is setup in such a way that server will fail to start unless the database redis servers are up and running.
• Here we are using two instances of redis database servers, one to store user data and one to maintain user login session

Makefile

• Comes with a Makefile to start the server.
• All you have to do to run the server is make build
• Then just do make up to run the containers and start up the servers.
• To stop do ctrl+c and to remove all containers and related services, use make down
