// Test script for project page SSR fixes
console.log('🧪 Testing Project Page SSR Fixes...\n');

console.log('🔧 SSR Issues Fixed:');
console.log('✅ Converted project details page from SSR to CSR');
console.log('✅ Added proper loading and error states');
console.log('✅ Fixed fetch URL handling for client vs server contexts');
console.log('✅ Enhanced session handling to allow undefined sessions');
console.log('✅ Improved error handling and user feedback');

console.log('\n📋 Root Causes Addressed:');
console.log('1. SSR trying to fetch from localhost during build/render');
console.log('2. Session being undefined during server-side execution');
console.log('3. IPv6 connection issues (::1:3005) in server context');
console.log('4. Missing loading/error states for async operations');

console.log('\n🔄 Before vs After:');
console.log('BEFORE:');
console.log('- Server-side rendering with fetch calls');
console.log('- Session required during SSR (caused crashes)');
console.log('- No loading states for users');
console.log('- Hard crashes on connection failures');

console.log('\nAFTER:');
console.log('- Client-side rendering with proper async handling');
console.log('- Session optional (graceful degradation)');
console.log('- Loading spinners and error messages');
console.log('- Graceful fallbacks and retry options');

console.log('\n🎯 Expected Behavior:');
console.log('1. Page loads with loading spinner');
console.log('2. Project data fetches on client-side');
console.log('3. Session is handled gracefully (optional)');
console.log('4. Error states show user-friendly messages');
console.log('5. No more server-side fetch failures');

console.log('\n🚀 Testing Instructions:');
console.log('1. Start the app: npm run dev');
console.log('2. Navigate to any project: /en/projects/[projectId]');
console.log('3. Should see loading spinner initially');
console.log('4. Page should load without server errors');
console.log('5. Check server logs - no more ECONNREFUSED errors');

console.log('\n🐛 Debug Information:');
console.log('- Browser: Check network tab for API calls');
console.log('- Server: Look for "session ====" logs');
console.log('- Console: No more "fetch failed" errors');
console.log('- PM2 logs: No more connection refused errors');
