2. Navigate to the project directory:

   cd pollingAPIRevamp
   

3. Install dependencies:

   npm install
   

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

   - PORT=5000
   - MONGODB_URI=your_mongodb_connection_string
   - JWT_SECRET=your_jwt_secret_key
   - JWT_EXPIRESIN = 5h

5. Start the server:

   npm start
   

To use the API, you can interact with it using tools like Postman, cURL, or any other HTTP client.

• Only administrators can create, update, and delete questions and options.

• Regular users have view-only access to questions and options.

• POST /v2/user/signup: Register a new user.

    curl -X POST http://localhost:5000/v2/user/signup \
--header 'Content-Type: application/json' \
--data-raw '{
    "name": "exampleuser",
    "email": "[email protected]",
    "phoneNo": "123456789",
    "password": "examplepassword"
}'
