Node.js JWT Authentication with MongoDB

This project provides a foundational setup for generating JSON Web Tokens (JWT) to access RESTful APIs using Node.js and MongoDB. The application is built with Express.js and includes user authentication functionality.

Features

• User Authentication: Secure user login and registration using JWT.
• API Endpoints: RESTful APIs for user management and authentication.
• Database Integration: MongoDB for data storage.
• Dependencies:
  • bcryptjs for password hashing.
  • body-parser for parsing request bodies.
  • express for server setup.
  • jsonwebtoken for token generation and validation.
  • mongoose for MongoDB interaction.

Installation

1. Clone the repository:

git clone https://github.com/Progesh/nodejs-jwt-mongodb.git
cd nodejs-jwt-mongodb  

2. Install the dependencies:

npm install  

3. Start the MongoDB server:

mongod  

4. Start the Node.js server:

node server.js  

5. Test the APIs using tools like Postman.
