+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Adopt-a-Street is a community street adoption platform with a React frontend and Node.js/Express backend. Users can adopt streets, complete maintenance tasks, participate in events, and earn rewards through a gamification system.
+
+## Development Status
+
+**This project is in active development and NOT in production.** Breaking changes are allowed and encouraged to improve code quality, architecture, and maintainability. Feel free to:
+- Refactor code structures and patterns
+- Change APIs and data models
+- Update dependencies and migrate to better solutions
+- Restructure the codebase for improved architecture
+- Make backward-incompatible changes that enhance the application
+
+## Architecture
+
+### Monorepo Structure
+- `frontend/`: React application (Create React App)
+- `backend/`: Express API server with MongoDB
+
+### Backend Architecture
+The backend follows a standard Express MVC pattern:
+- `server.js`: Main entry point with Socket.IO for real-time updates
+- `routes/`: API route handlers for auth, streets, tasks, posts, events, rewards, reports, ai, payments, users
+- `models/`: Mongoose schemas (User, Street, Task, Post, Event, Reward, Report)
+- `middleware/auth.js`: JWT authentication middleware using `x-auth-token` header
+
+### Frontend Architecture
+React SPA using React Router v5:
+- `App.js`: Main router with client-side routing
+- `context/AuthContext.js`: Global authentication state management
+- `components/`: Feature components (MapView, TaskList, SocialFeed, Profile, Events, Rewards, Premium, Login, Register, Navbar)
+
+Authentication flow: JWT tokens stored in localStorage and sent via `x-auth-token` header on all API requests.
+
+Frontend proxies API requests to `http://localhost:5000` in development.
+
+## Development Commands
+
+### Backend
+```bash
+cd backend
+npm install
+# Create .env file with MONGO_URI, JWT_SECRET, PORT
+node server.js  # Start backend on port 5000
+npx eslint .    # Run linter
+```
+
+### Frontend
+```bash
+cd frontend
+npm install
+npm start       # Start dev server on port 3000
+npm test        # Run tests in watch mode
+npm run build   # Production build
+```
+
+## Environment Variables
+
+Backend requires `.env` file:
+- `MONGO_URI`: MongoDB connection string
+- `JWT_SECRET`: Secret for JWT signing
+- `PORT` (optional): Server port (defaults to 5000)
+
+## API Endpoints
+
+- `/api/auth`: Registration, login, and user authentication
+- `/api/streets`: Street data and adoption management
+- `/api/tasks`: Maintenance task CRUD operations
+- `/api/posts`: Social feed posts
+- `/api/events`: Community events with Socket.IO real-time updates
+- `/api/rewards`: Points and rewards system
+- `/api/reports`: Street condition reports
+- `/api/ai`: AI-powered suggestions and insights
+- `/api/payments`: Premium subscription management (currently mocked)
+- `/api/users`: User profile management
+
+## Key Technologies
+
+- Frontend: React 19, React Router v5, Leaflet (mapping), Axios, Socket.IO client, Stripe.js
+- Backend: Express, Mongoose (MongoDB), JWT, bcryptjs, Socket.IO, Stripe, Multer (file uploads)
+- Testing: React Testing Library, Jest
+
+## Socket.IO Events
+
+Real-time features for events:
+- `joinEvent(eventId)`: Join event room
+- `eventUpdate`: Broadcast updates to event participants
+
+## Deployment
+
+### Kubernetes Raspberry Pi Cluster
+
+This application is deployed on a Kubernetes cluster running on Raspberry Pi hardware:
+
+**Cluster Configuration:**
+- **2x Raspberry Pi 5 (8GB RAM)** - Primary worker nodes for application workloads
+- **1x Raspberry Pi 3B+ (1GB RAM)** - Worker node for lightweight services
+
+**Architecture Considerations:**
+- ARM64 architecture (Pi 5) and ARMv7 architecture (Pi 3B+)
+- Multi-arch Docker images required (linux/arm64, linux/arm/v7)
+- Resource-constrained environment - optimize for low memory usage
+- Frontend and backend should be containerized separately
+- MongoDB should run as a StatefulSet with persistent storage
+- Consider resource limits and requests appropriate for Pi hardware
+
+**Deployment Strategy:**
+- Use Kubernetes manifests or Helm charts
+- Implement horizontal pod autoscaling based on available resources
+- Place memory-intensive workloads (backend, MongoDB) on Pi 5 nodes
+- Place frontend static serving on any node (lightweight)
+- Use NodeAffinity/NodeSelector to control pod placement
+- Implement health checks and readiness probes
+- Use ConfigMaps for environment variables
+- Use Secrets for sensitive data (JWT_SECRET, CLOUDINARY credentials, etc.)
+
+See deployment documentation for Kubernetes manifests and deployment instructions.
+
+## Testing
+
+Comprehensive test infrastructure is in place for both backend and frontend.
+
+### Running Tests

+```
+
+Frontend:
+```bash
+cd frontend
+npm test              # Run in watch mode
+npm run test:coverage # Run with coverage report
+```
+
+### Test Coverage

+## Overview
+
+The Adopt-a-Street application uses a comprehensive testing strategy covering both backend and frontend:
+
+- **Backend**: Jest + Supertest + MongoDB Memory Server
+- **Frontend**: React Testing Library + Jest + MSW (Mock Service Worker)
+- **Current Coverage**:
+  - Backend: ~55% statement coverage (109 passing tests)
+  - Frontend: MSW infrastructure in place with component tests
+
+## Backend Testing
+
+### Test Infrastructure
+
+The backend uses:
+- **Jest**: Test runner and assertion library
+- **Supertest**: HTTP assertions for API endpoint testing
+- **MongoDB Memory Server**: In-memory MongoDB for isolated testing
+- **Cross-env**: Environment variable management
+
+### Setup Files
+
+#### `backend/jest.config.js`
+
+```javascript
+module.exports = {
+  testEnvironment: 'node',
+  coverageDirectory: 'coverage',
+  collectCoverageFrom: [
+    'routes/**/*.js',
+    'middleware/**/*.js',
+    'models/**/*.js',
+    '!**/node_modules/**',
+    '!**/coverage/**'
+  ],
+  testMatch: [
+    '**/__tests__/**/*.test.js',
+    '**/?(*.)+(spec|test).js'
+  ],
+  coverageThreshold: {
+    global: {
+      branches: 70,
+      functions: 70,
+      lines: 70,
+      statements: 70
+    }
+  },
+  setupFilesAfterEnv: ['<rootDir>/__tests__/setup.js'],
+  testTimeout: 30000,
+  verbose: true
+};
+```
+
+#### `backend/__tests__/setup.js`
+
+Sets up MongoDB Memory Server for all tests:
+- Creates in-memory MongoDB instance before all tests
+- Clears collections after each test
+- Closes connections after all tests
+- Suppresses console logs during tests
+
+### Test Files
+
+#### Route Tests (`__tests__/routes/`)
+
+- `auth.test.js` - Authentication endpoints (register, login, get user)
+- `streets.test.js` - Street CRUD operations and adoption

+
+### Example Backend Test
+
+```javascript
+const request = require('supertest');
+const express = require('express');
+const authRoutes = require('../../routes/auth');
+const { createTestUser } = require('../utils/testHelpers');
+
+const app = express();
+app.use(express.json());
+app.use('/api/auth', authRoutes);
+
+describe('Auth Routes', () => {
+  it('should register a new user', async () => {
+    const response = await request(app)
+      .post('/api/auth/register')
+      .send({
+        name: 'John Doe',
+        email: 'john@example.com',
+        password: 'password123',
+      })
+      .expect(200);
+
+    expect(response.body).toHaveProperty('token');
+  });
+});
+```
+
+## Frontend Testing
+
+### Test Infrastructure
+
+The frontend uses:
+- **React Testing Library**: Component testing utilities
+- **Jest**: Test runner (via react-scripts)
+- **MSW (Mock Service Worker)**: API mocking
+- **@testing-library/user-event**: User interaction simulation
+
+### Setup Files

+#### `frontend/src/setupTests.js`
+
+- Configures Jest-DOM matchers
+- Sets up MSW server for API mocking
+- Mocks localStorage and window.matchMedia
+- Suppresses expected console warnings
+
+#### `frontend/src/mocks/handlers.js`
+
+Defines MSW handlers for all API endpoints:
+- Authentication (register, login, get user)
+- Streets (list, adopt)
+- Tasks (list, create, complete)
+- Posts (list, create, like)
+- Events (list, create, RSVP)
+- Rewards (list, redeem)
+- Users (get, update)
+
+### Test Files
+
+#### Component Tests (`src/components/__tests__/`)
+
+- `Login.test.js` - Login form validation and submission
+- `Register.test.js` - Registration form validation
+- `ErrorBoundary.test.js` - Error handling component
+
+#### Integration Tests (`src/__tests__/`)

+import Login from '../Login';
+import { AuthContext } from '../../context/AuthContext';
+
+describe('Login Component', () => {
+  it('should render login form', () => {
+    render(
+      <BrowserRouter>
+        <AuthContext.Provider value={mockContext}>
+          <Login />
+        </AuthContext.Provider>
+      </BrowserRouter>
+    );
+
+    expect(screen.getByPlaceholderText(/email/i)).toBeInTheDocument();

+```
+
+## Best Practices
+
+### Backend Testing
+
+1. **Use Test Helpers**: Leverage `testHelpers.js` for consistent test data creation
+2. **Isolate Tests**: Each test should be independent and not rely on other tests
+3. **Mock External Services**: Mock Cloudinary, Stripe, and other external APIs
+4. **Test Error Cases**: Don't just test happy paths, test error handling
+5. **Use Descriptive Names**: Test names should clearly describe what they test
+6. **Clean Up**: The test setup automatically cleans up between tests
+
+### Frontend Testing
+
+1. **Test User Behavior**: Focus on how users interact with components
+2. **Use MSW for API Mocking**: Don't mock axios directly, use MSW handlers
+3. **Test Accessibility**: Use semantic queries (getByRole, getByLabelText)
+4. **Avoid Implementation Details**: Test what users see, not component internals
+5. **Use waitFor for Async**: Always use waitFor for asynchronous operations
+6. **Mock External Libraries**: Mock Leaflet, Socket.IO, and other heavy libraries
+
+### Writing New Tests
+
+#### Backend Route Test Template
+
+```javascript
+const request = require('supertest');
+const express = require('express');
+const yourRoute = require('../../routes/your-route');
+const { createTestUser } = require('../utils/testHelpers');
+
+const app = express();
+app.use(express.json());
+app.use('/api/your-route', yourRoute);
+
+describe('Your Route', () => {
+  describe('GET /api/your-route', () => {
+    it('should do something', async () => {
+      const { token } = await createTestUser();
+
+      const response = await request(app)
+        .get('/api/your-route')
+        .set('x-auth-token', token)
+        .expect(200);
+
+      expect(response.body).toMatchObject({ /* expected shape */ });
+    });
+  });
+});
+```
+
+#### Frontend Component Test Template
+
+```javascript
+import { render, screen, fireEvent, waitFor } from '@testing-library/react';
+import YourComponent from '../YourComponent';
+
+describe('YourComponent', () => {
+  it('should render and work', async () => {
+    render(<YourComponent />);
+
+    const button = screen.getByRole('button', { name: /submit/i });
+    fireEvent.click(button);
+
+    await waitFor(() => {
+      expect(screen.getByText(/success/i)).toBeInTheDocument();
+    });
+  });
+});
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### MongoDB Memory Server Timeout
+
+If tests timeout with MongoDB Memory Server:
+
+```bash
+# Increase timeout in jest.config.js
+testTimeout: 30000  // 30 seconds
+```
+
+#### MSW Not Intercepting Requests
+
+Ensure MSW server is set up in `setupTests.js`:
+
+```javascript
+import { server } from './mocks/server';
+
+beforeAll(() => server.listen({ onUnhandledRequest: 'warn' }));
+afterEach(() => server.resetHandlers());
+afterAll(() => server.close());
+```
+
+#### React Router Errors in Tests
+
+Wrap components with BrowserRouter:
+
+```javascript
+import { BrowserRouter } from 'react-router-dom';
+
+render(
+  <BrowserRouter>
+    <YourComponent />
+  </BrowserRouter>
+);
+```
+
+#### Auth Context Not Found
+
+Provide AuthContext in tests:
+
+```javascript
+import { AuthContext } from '../../context/AuthContext';
+
+const mockAuthContext = {
+  auth: { isAuthenticated: false, loading: false, user: null },
+  login: jest.fn(),
+};
+
+render(
+  <AuthContext.Provider value={mockAuthContext}>
+    <YourComponent />
+  </AuthContext.Provider>
+);
+```
+
+#### Leaflet Map Errors
+
+Mock react-leaflet in tests:
+
+```javascript
+jest.mock('react-leaflet', () => ({
+  MapContainer: ({ children }) => <div data-testid="map">{children}</div>,
+  TileLayer: () => null,
+  Marker: () => null,
+  Popup: () => null,
+}));
+```
+
+### Performance Tips
+
+1. **Run specific test files**:
+   ```bash
+   npm test -- auth.test.js
+   ```
+
+2. **Run tests matching pattern**:
+   ```bash
+   npm test -- --testNamePattern="login"
+   ```
+
+3. **Skip tests during development**:
+   ```javascript
+   describe.skip('Skip this suite', () => { /* ... */ });
+   it.skip('Skip this test', () => { /* ... */ });
+   ```
+
+4. **Run only specific tests**:
+   ```javascript
+   describe.only('Run only this suite', () => { /* ... */ });
+   it.only('Run only this test', () => { /* ... */ });
+   ```
+

+# Testing Quick Start Guide
+
+Quick reference for running tests in the Adopt-a-Street application.
+
+## TL;DR - Run Tests Now
+
+```bash
+# Backend tests
+cd backend && npm test
+
+# Frontend tests
+cd frontend && npm test
+
+# Backend with coverage
+cd backend && npm run test:coverage
+
+# Frontend with coverage
+cd frontend && npm run test:coverage
+```
+
+## What's Been Tested
+
+### Backend (54.75% coverage, 109 passing tests)
+✅ Authentication (register, login, get user)
+✅ Streets (CRUD, adoption)
+✅ Tasks (create, complete, update)
+✅ Posts (create, like, comment)
+✅ Events (create, RSVP)
+✅ Rewards (list, redeem)
+✅ Reports (create, resolve)
+✅ User model (validation, relationships)
+✅ Street model (GeoJSON, geospatial)
+✅ Task model (status, assignment)
+✅ Post model (likes, comments)
+✅ Auth middleware (JWT validation)
+
+### Frontend (Infrastructure ready)
+✅ Login component (form, validation, submission)
+✅ Register component (form, validation, password matching)
+✅ ErrorBoundary (error catching, fallback UI)
+✅ Auth flow integration (login → register → logout)
+✅ MSW API mocking (all endpoints)
+
+## Common Commands
+
+### Backend
+
+```bash
+cd backend
+
+# Watch mode (TDD)
+npm run test:watch
+
+# Single test file
+npm test -- auth.test.js
+
+# Tests matching pattern
+npm test -- --testNamePattern="login"
+
+# Coverage report
+npm run test:coverage
+
+# Verbose output
+npm run test:verbose
+
+# Update snapshots
+npm test -- -u
+```
+
+### Frontend
+
+```bash
+cd frontend
+
+# Watch mode (default)
+npm test
+
+# Coverage report
+npm run test:coverage
+
+# Single test file
+npm test -- Login.test.js
+
+# Tests matching pattern
+npm test -- --testNamePattern="should render"
+
+# No watch mode
+CI=true npm test
+
+# Update snapshots
+npm test -- -u
+```
+
+## Writing Your First Test
+
+### Backend Route Test
+
+```javascript
+const request = require('supertest');
+const express = require('express');
+const yourRoute = require('../../routes/your-route');
+const { createTestUser } = require('../utils/testHelpers');
+
+const app = express();
+app.use(express.json());
+app.use('/api/your-route', yourRoute);
+
+describe('Your Route', () => {
+  it('should work', async () => {
+    const { token } = await createTestUser();
+
+    const response = await request(app)
+      .get('/api/your-route')
+      .set('x-auth-token', token)
+      .expect(200);
+
+    expect(response.body).toHaveProperty('data');
+  });
+});
+```
+
+### Frontend Component Test
+
+```javascript
+import { render, screen, fireEvent } from '@testing-library/react';
+import YourComponent from '../YourComponent';
+
+describe('YourComponent', () => {
+  it('should render', () => {
+    render(<YourComponent />);
+
+    const button = screen.getByRole('button');
+    fireEvent.click(button);
+
+    expect(screen.getByText(/success/i)).toBeInTheDocument();
+  });
+});
+```
+
+## Test Helpers Available
+
+### Backend
+
+```javascript
+const {
+  createTestUser,       // Returns { user, token }
+  createTestUsers,      // Creates multiple users
+  createTestStreet,     // Creates street with location
+  createTestTask,       // Creates task
+  createTestPost,       // Creates post
+  createTestEvent,      // Creates event
+  createTestReward,     // Creates reward
+  createTestReport,     // Creates report
+} = require('../utils/testHelpers');
+```
+
+### Frontend
+
+MSW handlers automatically mock all API endpoints:
+- `/api/auth/*` - Authentication
+- `/api/streets/*` - Streets
+- `/api/tasks/*` - Tasks
+- `/api/posts/*` - Posts
+- `/api/events/*` - Events
+- `/api/rewards/*` - Rewards
+- `/api/users/*` - Users
+
+## Coverage Reports
+
+After running tests with coverage, open the HTML report:
+
+```bash
+# Backend
+cd backend && npm run test:coverage
+open coverage/lcov-report/index.html
+
+# Frontend
+cd frontend && npm run test:coverage
+open coverage/lcov-report/index.html
+```
+
+## Current Coverage Status
+
+### Backend
+- Overall: 54.75%
+- Auth middleware: 100% ✅
+- Models: 82.50% ✅
+- Routes: 45.84% ⚠️
+
+### Frontend

+
+## Troubleshooting
+
+### Backend
+
+**Tests timeout**
+```bash
+# Increase timeout in jest.config.js
+testTimeout: 30000
+```
+
+**MongoDB connection issues**
+```bash
+# Check MongoDB Memory Server is installed
+npm list mongodb-memory-server
+```
+
+### Frontend
+
+**MSW not intercepting**
+```javascript
+// Check setupTests.js has:
+beforeAll(() => server.listen());
+afterEach(() => server.resetHandlers());
+afterAll(() => server.close());
+```
+
+**React Router errors**
+```javascript
+// Wrap component with BrowserRouter
+import { BrowserRouter } from 'react-router-dom';
+
+render(
+  <BrowserRouter>
+    <YourComponent />
+  </BrowserRouter>
+);
+```
+
+**Auth context errors**
+```javascript
+// Provide AuthContext
+import { AuthContext } from '../../context/AuthContext';
+
+const mockContext = {
+  auth: { isAuthenticated: false, loading: false },
+  login: jest.fn(),
+};
+
+render(
+  <AuthContext.Provider value={mockContext}>
+    <YourComponent />
+  </AuthContext.Provider>
+);
+```

+## Known Issues & Limitations
+
+### Backend
+
+1. **Schema Mismatches** (67 failing tests)
+   - Task model tests expect fields not in actual schema
+   - Solution: Update Task.test.js to match actual Task model
+   - Impact: Reduces passing tests but doesn't affect actual functionality
+
+2. **Coverage Below Target**
+   - Routes: 45.84% (target: 70%)
+   - Middleware: 40.24% (target: 70%)
+   - Solution: Add more edge case tests and error scenario tests
+
+3. **Untested Areas**
+   - Socket.IO authentication: 0%
+   - AI routes: 0%
+   - Payment routes: 0%
+   - File upload middleware: 35.29%
+
+### Frontend
+
+1. **Limited Component Coverage**
+   - Only 3 components tested (Login, Register, ErrorBoundary)
+   - Missing tests: MapView, TaskList, SocialFeed, Events, Profile, Premium, Rewards
+   - Solution: Create tests for remaining components
+
+2. **No E2E Tests**
+   - Only unit and integration tests
+   - Solution: Add Playwright or Cypress for E2E testing
