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
- Install React Developer Tools browser extension
- Use Components tab to inspect component state
- 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 (
<pre>{JSON.stringify(session, null, 2)}</pre>
)
}
🔄 Performance Debugging
React Performance Issues
// Use React Profiler
import { Profiler } from 'react'
function onRenderCallback(id, phase, actualDuration) {
console.log('Component render:', { id, phase, actualDuration })
}
<Profiler id="EntityList" onRender={onRenderCallback}>
<EntityList />
</Profiler>
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
})
}
}
