What are some best practices for strategically placing Sentry Error Boundaries within a complex Next.js application?

Strategic placement of Error Boundaries in Next.js enhances error resilience and provides better user experience: 1. **Top-level (in `_app.js`):** Wrap the entire application to catch most client-side rendering errors, providing a global fallback and ensuring no unhandled client-side UI crash. This is essential for a baseline of stability. 2. **Feature-level:** Wrap larger, independent sections or features of your application (e.g., a complex dashboard, a user profile module) with their own Error Boundaries. This isolates errors to a specific part, allowing other parts of the application to remain functional and potentially offering a more context-specific fallback UI. 3. **Critical Component-level:** For highly critical or volatile components that might frequently fail (e.g., third-party widgets, complex data visualizations), wrap them individually. This prevents an error in one small component from taking down a whole feature or page. 4. **Avoid over-wrapping:** Do not wrap every single component, as it can add unnecessary overhead and make error diagnosis more complex by creating too many distinct error contexts. Balance granularity with maintainability and performance.
