how to implement an authentication system using Node.js, Express, MongoDB & JSON web tokens (JWT).

Full-Stack Node.js Application with Express Backend, MongoDB, and JWT Authentication

Overview

This repository contains a full-stack Node.js application with Express.js for the backend, MongoDB as the database, and JWT (JSON Web Token) authentication. The frontend is also built using Express to serve static files.

Features

JWT Authentication: Implements secure user authentication using JSON Web Tokens. Express.js Backend: A robust backend framework with routing and middleware support. MongoDB Integration: Utilizes MongoDB as the database for data storage. Frontend with Express: Express serves static files for the frontend interface. Modular Structure: Codebase is organized into modules for easy maintenance and scalability.

Prerequisites

Before running the application, ensure you have the following installed:

Node.js and npm MongoDB Git (optional) Getting Started Clone the Repository:

[email protected]:Gmatieso/node-express-jwt-auth.git
cd node-express-jwt-auth

Install Dependencies:

npm install

Configure Environment Variables:

Create a .env file in the root directory with the following variables:

env

PORT=3000
MONGODB_URI=your_mongodb_connection_string
JWT_SECRET=your_jwt_secret_key

Configure the Database:

Create a MongoDB database and obtain the connection URI. Update the config/db.js file with your MongoDB URI. Run the Application:

nodemon app

The application will be accessible at http://localhost:3000.
