• Node.js 18+
• PostgreSQL database
• npm or yarn

1. Navigate to backend directory:

   cd backend

2. Install dependencies:

   npm install

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

   DATABASE_URL=postgresql://username:password@localhost:5432/potty_buddy
   PORT=3001
   NODE_ENV=development
   FRONTEND_URL=http://localhost:3000

4. Start the development server:

   npm run dev

The backend will be available at http://localhost:3001

1. Navigate to frontend directory:

   cd frontend

2. Install dependencies:

   npm install

3. Start the development server:

   npm run dev

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

The application uses PostgreSQL with the following schema:

-- Users table
CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    username VARCHAR(50) UNIQUE NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- Events table
CREATE TABLE events (
    id SERIAL PRIMARY KEY,
    user_id INTEGER REFERENCES users(id) ON DELETE CASCADE,
    event_type VARCHAR(20) NOT NULL CHECK (event_type IN ('dirty_pants', 'potty')),
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

The tables will be created automatically when the backend starts.

• GET /api/users/:username - Check if username exists
• POST /api/users - Create new user

• POST /api/events - Log new event
• GET /api/events/:userId - Get user's events for statistics
