Error Handling & Source Code Protection in Next.js

This documentation provides a basic overview of error handling and source code protection in Next.js applications. For a comprehensive, step-by-step implementation guide, please refer to our detailed tutorial: Next.js Stealth Mode: Error Handling & Code Protection (opens in a new tab).

Quick Overview

Error Handling

Our implementation covers:

Custom error boundaries to catch React component errors
User-friendly error pages with retry capabilities
Structured error logging system
Environment-aware error reporting

Source Protection

Key security features include:

Source map protection in production
Console log removal in builds
Code minification strategies
Secure error display

Basic Implementation

// Basic error boundary setup
<ErrorBoundary fallback={<ErrorFallback />}>
  <YourComponent />
</ErrorBoundary>
 
// Simple error logging
try {
  // Your code
} catch (error) {
  logger.error(error);
}

Configuration

Quick start with Next.js config:

// next.config.js
module.exports = {
  productionBrowserSourceMaps: false
}
