JWT Authentication

This is my JWT_Authentication App it help When the client want to use the Authenticated things then it will run as a MIDDLEWARE to that and finds that if the user is login or they have the verified JWT_token then it allows to do it, otherwise redirect user to the Root ..

Overview

This repository contains a sample implementation of JSON Web Token (JWT) authentication. JWT is a compact, URL-safe means of representing claims to be transferred between two parties. It is commonly used for authentication and authorization purposes in web applications.

Features

• User Registration: Register new users with unique credentials.
• User Login: Authenticate users and generate JWT tokens for subsequent requests.
• Token Refresh: Allow users to refresh their JWT tokens to extend their session.
• Middleware: Implement middleware to protect routes that require authentication.

Technologies Used

• Node.js: JavaScript runtime for server-side development.
• Express.js: Web application framework for Node.js.
• jsonwebtoken: Library for generating and verifying JSON Web Tokens.
• MongoDB: NoSQL database for storing user information.
• dotenv: Module to load environment variables from a .env file.

Setup

1. Clone the repository:

git clone https://github.com/your-username/JWT_authentication.git
cd JWT_authentication
Install dependencies:

Copy code
npm install

Create a .env file in the project root and configure environment variables:

env

Copy code PORT=8000 // give your port here MONGODB_URI=mongodb://localhost:27017/userlist JWT_SECRET=your-secret-key // BeAMan Start the server:

bash

Copy code

npm start dev

The server should now be running at http://localhost:8000.

API Endpoints

POST /api/register: Register a new user. POST /api/login: Log in and receive a JWT token. POST /api/refresh-token: Refresh the JWT token. GET /api/protected-route: Example protected route requiring authentication. Usage Register a new user using the /api/register endpoint. Log in with the registered credentials using the /api/login endpoint to receive a JWT token. Use the token to access protected routes like /api/protected-route. To extend the session, use the /api/refresh-token endpoint with the refresh token. Contributors Your Name [email protected] License This project is licensed under the ISC License.
