Features

• User registration: Users can create an account by providing a unique username and password.
• User login: Registered users can log in using their credentials.
• User logout: Logged-in users can securely log out of their accounts.
• Password hashing: Passwords are securely hashed before being stored in the database for improved security.
• Session management: User sessions are managed using session cookies for authentication.
• User Profile update: Authorized users can update their profile information.

Technologies Used

• MongoDB: A NoSQL database used for storing user data.
• Express.js: A web application framework for Node.js used for building the server-side logic.
• Node.js: A JavaScript runtime environment used for executing JavaScript code on the server.

Installation

1. Clone the repository:

   git clone https://github.com/ESE-MONDAY/authentication-backend
   

2. Install dependencies:

   npm install
   

3. Set up environment variables:

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

   PORT=3000
   MONGODB_URI=<mongodb-uri>
   TOKEN_KEY=<whateverkeyyoupick>
   

   Replace <mongodb-uri> with the URI of your MongoDB database and <session-secret> with a random string used for session encryption.

4. Start the server:

   npm start
