Authentication Project

This is a simple authentication project built with Express, MongoDB, and several supporting libraries including CORS, Bcrypt.js, Crypto, and Mongoose. The application includes user registration, login, logout, password reset, email verification, and welcome emails.

Technologies Used

• Node.js with Express for the backend server
• MongoDB for the database
• Mongoose for object data modeling (ODM)
• Bcrypt.js for password hashing
• Crypto for generating secure tokens
• CORS for enabling Cross-Origin Resource Sharing
• dotenv for managing environment variables
• Nodemailer for sending emails (using Mailtrap)

Getting Started

Prerequisites

• Node.js (v14 or higher)
• MongoDB (local or cloud instance)

Setup

1. Clone the repository:

   git clone <your-repo-url>
   cd <your-repo-folder>

2. Create a .env file in the root directory of the project and add the following environment variables:

MONGO_URI=<your_mongo_db_connection_string>
PORT=5000
JWT_SECRET=<your_jwt_secret>
NODE_ENV=development
MAILTRAP_TOKEN=<your_mailtrap_token>
MAILTRAP_ENDPOINT=<your_mailtrap_endpoint>
CLIENT_URL=<your_client_url>

3. Install the required dependencies: npm i

4. Start the development server: npm run dev

Now the server is running on http://localhost:5000

API ENDPOINTS

You can test the API using Postman. Here are some key endpoints:

• Login POST /api/auth/login
• Logout POST /api/auth/logout
• Forgot Password POST /api/auth/forgot-password
• Reset Password POST /api/auth/reset-password/<tokenHere>
