+ );
+}
+```
+
+**Usage:**
+```tsx
+// Add to your app layout or any page
+import { SimpleEnvDebugger } from '@/components/debug/SimpleEnvDebugger';
+
+export default function Layout({ children }) {
+ return (
+
+
+ {children}
+
+
+
+ );
+}
+```
+
+**Pros:**
+- Visual interface in browser
+- Real-time environment monitoring
+- Interactive debugging control
+- Automatically hidden in production
+- Shows client-side environment variables
+
+**Cons:**
+- Requires React component integration
+- Only shows NEXT_PUBLIC_ variables
+- Client-side only
+

+
+## 5. Browser Dev Tools Console Approaches
+
+### 5.1 Console Helper Functions
+
+**Best for:** Manual debugging and ad-hoc testing
+
+**Implementation:**
+```typescript
+// lib/debug/consoleHelpers.ts
+export function debugEnv() {
+ console.group('š Environment Variables Debug');
+
+ // Client-side environment variables
+ const clientVars: Record = {};
+ for (const key in process.env) {
+ if (key.startsWith('NEXT_PUBLIC_')) {
+ clientVars[key] = process.env[key] || '';
+ }
+ }
+
+ console.log('š Environment Variable Count:', Object.keys(clientVars).length);
+ console.log('š Node Environment:', process.env.NODE_ENV);
+ console.log('ā° Timestamp:', new Date().toISOString());
+
+ if (Object.keys(clientVars).length > 0) {
+ console.table(clientVars);
+ } else {
+ console.warn('ā ļø No NEXT_PUBLIC_ environment variables found');
+ }
+
+ console.groupEnd();
+}
+
+export function debugRuntime() {
+ console.group('š§ Runtime Debug Info');
+
+ const runtimeInfo = {
+ userAgent: navigator.userAgent,
+ currentUrl: window.location.href,
+ timestamp: new Date().toISOString(),
+ viewportSize: `${window.innerWidth}x${window.innerHeight}`,
+ online: navigator.onLine,
+ language: navigator.language,
+ platform: navigator.platform,
+ };
+
+ console.table(runtimeInfo);
+ console.groupEnd();
+}
+
+export async function debugServerEnv() {
+ try {
+ console.group('š„ļø Server Environment Debug');
+ console.log('Fetching server environment info...');
+
+ const response = await fetch('/api/debug/env');
+
+ if (!response.ok) {
+ throw new Error(`HTTP ${response.status}: ${response.statusText}`);
+ }
+
+ const data = await response.json();
+
+ console.log('š Server Environment Summary:', data.totals);
+ console.log('š Server Timestamp:', data.timestamp);
+
+ // Log each category
+ Object.entries(data.categories).forEach(([category, vars]) => {
+ if (Object.keys(vars as Record).length > 0) {
+ console.group(`${category} (${Object.keys(vars as Record).length} vars)`);
+ console.table(vars);
+ console.groupEnd();
+ }
+ });
+
+ console.groupEnd();
+ } catch (error) {
+ console.error('ā Failed to fetch server environment:', error);
+ }
+}
+
+export function initConsoleHelpers() {
+ if (typeof window !== 'undefined' && process.env.NODE_ENV === 'development') {
+ // Add debug functions to window for easy console access
+ (window as any).debugEnv = debugEnv;
+ (window as any).debugRuntime = debugRuntime;
+ (window as any).debugServerEnv = debugServerEnv;
+
+ console.log('š§ Debug helpers initialized! Try:');
+ console.log(' ā¢ debugEnv() - Client environment variables');
+ console.log(' ā¢ debugRuntime() - Runtime information');
+ console.log(' ā¢ debugServerEnv() - Server environment via API');
+ }
+}
+```
+
+**Setup:**
+```tsx
+// Add to your app layout or _app.tsx
+import { initConsoleHelpers } from '@/lib/debug/consoleHelpers';
+
+export default function Layout({ children }) {
+ useEffect(() => {
+ initConsoleHelpers();
+ }, []);
+
+ return <>{children};
+}
+```
+
+**Usage:**
+1. Open browser dev tools console
+2. Type any of these commands:
+ - `debugEnv()` - Show client environment variables
+ - `debugRuntime()` - Show runtime info
+ - `debugServerEnv()` - Fetch and show server environment
+
+**Pros:**
+- Manual control over debugging
+- No UI clutter
+- Comprehensive information display
+- Works from browser console
+- Both client and server environment access
+
+**Cons:**
+- Requires manual console interaction
+- Must remember function names
+- Requires initial setup
+

+
+## 6. Minimal Configuration Debugging Methods
+
+### 6.1 Single Line Environment Check
+
+**Best for:** Quick environment validation
+
+```tsx
+// Add this single line anywhere in your code
+{process.env.NODE_ENV === 'development' && console.log('ENV_CHECK:', { NODE_ENV: process.env.NODE_ENV, FIREBASE_PROJECT: process.env.NEXT_PUBLIC_FIREBASE_PROJECT_ID })}
+```
+
+### 6.2 Simple Environment Display Component
+
+```tsx
+// One-liner debug component
+const EnvStatus = () => process.env.NODE_ENV === 'development' ?
+
+ {process.env.NODE_ENV} | {Object.keys(process.env).filter(k=>k.startsWith('NEXT_PUBLIC_')).length} vars
+
: null;
+```
+
+---
+
+## 7. Testing All Approaches
+
+### 7.1 Step-by-Step Testing Guide
+
+1. **Setup Environment Variables:**
+ ```bash
+ # Ensure you have environment variables set
+ echo "NEXT_PUBLIC_TEST_VAR=test_value" >> .env.development
+ ```
+
+2. **Test Console.log Approach:**
+ - Add console.log to any page component
+ - Start dev server: `pnpm run dev`
+ - Check terminal output
+
+3. **Test API Route:**
+ - Create the API route file
+ - Visit `http://localhost:3000/api/debug/env`
+ - Check JSON response
+
+4. **Test React Hook:**
+ - Add the hook and component to your app
+ - Look for floating debug button
+ - Click and check browser console
+
+5. **Test Console Helpers:**
+ - Add console helpers to your app
+ - Open browser dev tools
+ - Run `debugEnv()` in console
+
+### 7.2 Troubleshooting Common Issues
+
+**Problem: No environment variables showing**
+- Solution: Ensure variables start with `NEXT_PUBLIC_`
+- Check `.env.development` file exists and has correct format
+
+**Problem: API route returns 403**
+- Solution: Verify `NODE_ENV=development`
+- Check API route is in correct directory structure
+
+**Problem: Console functions not available**
+- Solution: Ensure `initConsoleHelpers()` is called
+- Check browser console for initialization messages
+
+**Problem: Component not rendering**
+- Solution: Verify component is added to layout
+- Check `NODE_ENV` is set to 'development'
+
+---
+
+## 8. Recommendations
+
+### 8.1 Best Practices
+
+1. **For Quick Debugging:** Use console.log in page components
+2. **For Comprehensive Analysis:** Use API route approach
+3. **For Interactive Debugging:** Use React hook with floating component
+4. **For Manual Testing:** Use browser console helpers
+
+### 8.2 When to Use Each Approach
+
+- **Console.log:** When you need immediate feedback during development
+- **API Route:** When you need to inspect server environment comprehensively
+- **Middleware:** When you need request-specific environment debugging
+- **React Hook:** When you want interactive client-side debugging
+- **Console Helpers:** When you need manual control and don't want UI elements
+
+### 8.3 Security Considerations
+
+- All approaches automatically disabled in production
+- Sensitive values are masked in API responses
+- No environment variables are exposed beyond what Next.js already makes available
+- Debug components and routes only work in development mode
+
+---
+
+## 9. Implementation Priority
+
+1. **Start with:** Simple console.log approach for immediate needs
+2. **Add:** API route for comprehensive server environment inspection
+3. **Consider:** React hook for interactive debugging if needed
+4. **Optional:** Middleware and console helpers for advanced scenarios
+
+All approaches are lightweight, require minimal configuration, and provide immediate feedback for environment variable debugging in Next.js applications.
