# Debugging & Troubleshooting

Systematic debugging approaches and solutions for common Ring Platform development issues.

## Debugging Strategies

### Development Environment Issues

#### Node.js Version Conflicts
Check Node.js version Use Node Version Manager

{`node --version  # Should be 18.x or higher

nvm install 18
nvm use 18`}

#### Package Installation Issues
Clear npm cache Remove node_modules and reinstall

{`npm cache clean --force

rm -rf node_modules package-lock.json
npm install`}

## 🚨 Common Build Errors

### TypeScript Errors

{`// Error: Property 'user' does not exist on type 'Session | null'
// Solution: Add proper type guards
if (session?.user) {
  console.log(session.user.name) // ✅ Safe access
}`}

### Next.js Build Issues
Clear Next.js cache Rebuild

{`rm -rf .next

npm run build`}

## 🔧 Runtime Debugging

### React DevTools
1. Install React Developer Tools browser extension
2. Use Components tab to inspect component state
3. Use Profiler to identify performance issues

### Console Debugging
// Structured logging

{`console.log('🔍 Debug:', { userId, entityId, timestamp: Date.now() })

// Conditional debugging
if (process.env.NODE_ENV === 'development') {
  console.log('Dev only debug info')
}`}

### Network Debugging
// API call debugging

{`const response = await fetch('/api/entities', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify(data)
})

console.log('API Response:', {
  status: response.status,
  headers: Object.fromEntries(response.headers),
  url: response.url
})`}

## 🗄️ Database Issues

### Firestore Connection Problems
// Check Firestore connection

{`import { db } from '@/lib/firebase'
import { doc, getDoc } from 'firebase/firestore'

try {
  const testDoc = await getDoc(doc(db, 'test', 'connection'))
  console.log('✅ Firestore connected')
} catch (error) {
  console.error('❌ Firestore connection failed:', error)
}`}

### Authentication Issues
// Debug Auth.js session

{`import { auth } from '@/auth'

export default async function DebugPage() {
  const session = await auth()
  
  return (
    {JSON.stringify(session, null, 2)}
  )
}`}

## 🔄 Performance Debugging

### React Performance Issues
// Use React Profiler

{`import { Profiler } from 'react'

function onRenderCallback(id, phase, actualDuration) {
  console.log('Component render:', { id, phase, actualDuration })
}

  
`}

### Bundle Analysis
Analyze bundle size Check for large dependencies

{`npm run build
npm run analyze

npx webpack-bundle-analyzer .next/static/chunks/`}

## 🚀 Production Debugging

### Error Tracking
// Sentry integration

{`import * as Sentry from '@sentry/nextjs'

Sentry.captureException(error, {
  tags: {
    component: 'EntityCreation',
    userId: session?.user?.id
  }
})`}

### Performance Monitoring
// Web Vitals tracking

{`export function reportWebVitals(metric) {
  console.log(metric)
  
  // Send to analytics
  if (metric.label === 'web-vital') {
    gtag('event', metric.name, {
      value: Math.round(metric.value),
      event_label: metric.id
    })
  }
}`}
