Frontend

The frontend is built using React and styled-components, providing a dynamic and responsive user interface.

Frontend Technologies Used

• React
• React Router DOM (v6)
• Styled Components
• Formik & Yup (for form handling)
• Axios (for API requests)
• Context API (for state management)

Frontend Setup

1. Navigate to the client directory:

   cd client

2. Install dependencies:

   npm install

3. Start the development server:

   npm start

   The frontend will be available at http://localhost:3000.

Frontend Key Features

• User authentication (login, signup, logout)
• Theme toggling (light/dark mode)
• Admin protected routes
• Contest solutions display
• API data fetching and display

Backend

The backend is built using [Specify your backend technology, e.g., Node.js with Express], providing the API endpoints for the frontend.

Backend Technologies Used

• Node.js
• Express.js
• MongoDB Mongoose
• CORS, Middleware
• jsonwebtoken

Backend Setup

1. Navigate to the server directory:

   cd server

2. Install dependencies:

   npm install

3. Start the server:

   npm start

   The backend will be available at http://localhost:5000 (or your defined port).

API Endpoints

• GET /contests: Retrieves a list of contests.
• GET /solutions: Retrieves a list of solution links.
• POST /solutions: Adds a new solution link.
• POST /login: Authenticates a user and returns a JWT.
• POST /signup: Creates a new user account.

Environment Variables

Create a .env file in the root directory to store environment variables.

Running the Application

1. Start the backend server in the server directory:

   cd server
   npm start

2. Start the frontend development server in the client directory:

   cd client
   npm start

3. Open your browser and navigate to http://localhost:3000.

Troubleshooting

• "Cannot read properties of undefined (reading 'body')": This error usually indicates a problem with the Theme Context. Ensure ThemeProvider is correctly wrapping your App component in index.js. Verify the contents of ThemeContext.js and styles/theme.js.
• "Request failed with status code 404": This error means the frontend is trying to access a backend endpoint that doesn't exist. Double-check your API_BASE_URL in services/api.js and verify that the backend is running and the routes are defined. Use Postman or Insomnia to test the backend endpoints directly.
• "fetchSolutionLinks is not defined": This error means that the function is not being imported correctly. Double check the import statement, and make sure that the function is exported correctly from the api.js file.
• CORS issues: If the backend and frontend are on different origins, make sure your backend is configured to allow CORS requests.
