• Node.js (v14 or later)
• npm or yarn
• MongoDB

🚀 Getting Started

1. Clone the repository:

git clone https://github.com/wassimOubaziz/PRODIGY_FS_01.git

1. Install dependencies:

npm install

or

yarn install

1. Set up environment variables: Create a .env.local file in the root directory and add the following:

MONGODB_URI=your_mongodb_connection_string
JWT_SECRET=your_jwt_secret_key

1. Run the development server:

npm run dev

or

🔒 Authentication Flow

1. Registration: Users can create an account by providing a username, email, and password. Passwords are hashed using bcrypt before being stored in the database.

1. Login: Users can log in using their email and password. Upon successful authentication, a JWT token is generated and stored in the browser’s local storage.

2. Protected Routes: Certain routes (e.g., dashboard) are protected and can only be accessed by authenticated users. The JWT token is used to verify the user’s identity.

1. Logout: Users can log out, which removes the JWT token from local storage and redirects them to the login page.

🎨 UI Components

• Button: A reusable button component with consistent styling.
• Input: A styled input component for form fields.
• AuthForm: A flexible form component used for both login and registration.
• Navbar: A responsive navigation bar with dynamic content based on authentication status.

🔐 Security Considerations

• Passwords are hashed using bcrypt before storage.
• JWT tokens are used for maintaining user sessions.
• Protected routes are implemented using middleware to verify authentication.
• CORS is configured to restrict access to the API.
• Rate limiting is implemented to prevent brute-force attacks.

🚀 Deployment

This application can be easily deployed to platforms like Vercel or Netlify. Make sure to set up the required environment variables in your deployment platform.
