1. Clone the repository:

   git clone https://github.com/Fingertips18/mern-auth.git

2. Install dependencies:

   npm install

3. Set up environment variables. Create a .env file in the root directory::

   PORT=<PORT>
   MONGO_URI=<MONGO_URI>
   JWT_SECRET=<JWT_SECRET>
   NODE_ENV=<NODE_ENV>
   EMAILJS_SERVICE_ID=<EMAILJS_SERVICE_ID>
   EMAILJS_TEMPLATE_ID=<EMAILJS_TEMPLATE_ID>
   EMAILJS_PUBLIC_KEY=<EMAILJS_PUBLIC_KEY>
   EMAILJS_PRIVATE_KEY=<EMAILJS_PRIVATE_KEY>
   CLIENT_URL=<CLIENT_URL>

4. Run the backend server:

   npm run dev

⚛️ Frontend (React JS)

1. Navigate to the frontend directory:

   cd frontend

2. Install dependencies:

   npm install

3. Set up environment variables. Create a .env.local file in the frontend directory:

   VITE_BASE_URL=<VITE_BASE_URL>

4. Run the frontend server:

   npm run dev

📡 API Endpoints

• Root:

  • GET /: The root of the server

• Authentication:

  • POST /api/auth/sign-up : Register a new user.

  • POST /api/auth/sign-in : Log in a user and return a JWT.

  • POST /api/auth/sign-out : Log out a user and clear the session.

  • POST /api/auth/verify-email : Verify a user's email address.

  • POST /api/auth/forgot-password : Send a password reset email.

  • POST /api/auth/reset-password : Reset a user's password.
