Auth-Redis-Nest

This Project demonstrate the Authenication module with Redis implmentation.
The purpose of this project is to implemented the redis with the NestJs
It is build with NestJs framework with MongoDB as Database and Redis database to store and verify OTP authenication.

Prerequisites

Tech should be installed before running the application

  1. NestJs
  2. Docker
  3. Redis
  4. MongoDB
  5. Postman (To execute the APIs)

Installing Guide

After cloning the project
Install Npm libraries using   npm i

Add .env file in the root folder with variables 

DB_URL
#REDIS
REDIS_HOST
REDIS_PORT

To Run

Run redis in docker
Connect with Database
Run npm run start:dev to run the application
If everything is good you won't see red lines else you have stackoverflow to debug.

Brief Info about project

This is build with NestJs framework. I have created auth module which includes CRUD APIs with login and OTP verfication which is implmented using redis database. Later I have discussed more about redis.

Here, User can do the following actions:

  1. Create User
  2. Login User
  3. Get all Users
  4. Get User by Id
  5. Update User
  6. Delete User
  7. Request Otp for User
  8. Verfiy Otp for User

I have use argon2 library for hashing. Redis for OTP verfication as it gives more feature above normal database.
It stores at key value pair so you don't have to manage the occurence of redundany. It has Time to live (TTL) which can be used to expire otp in certain specified time.

POSTMAN file for the APIs

Copy and paste below code in a file with .json extension and import it in the postman

{
	"info": {
		"_postman_id": "68a8f2e8-24a7-4533-9337-1df99e9f17ad",

	},
	"item": [

	]
}

Things can be improve

  1. I have added dtos for some APIs you can added them
  2. Tokens were not scope of my agenda but you can added them for session
  3. Caching can be added for quick response like for getAll users

Please add suggestion if you thing something is not right. Help us to improve

Keep coding
