Does this support React 18 and 19 features?

Yes, it covers modern patterns including Server Components, concurrent features, and newer hooks like useEffectEvent to prevent stale closures.

Can it help with Next.js hydration errors?

Absolutely. It identifies causes for server/client mismatches such as browser-only APIs or random values and suggests strategies like useEffect-based initialization or suppressHydrationWarning.

How does this skill handle infinite re-render loops?

The skill analyzes state updates within render cycles and useEffect dependency arrays to identify recursive triggers, providing optimized patterns to move updates to event handlers or memoized effects.

What tools does this skill recommend for debugging?

It provides guidance on using React Developer Tools (Components and Profiler tabs), Error Boundaries, Strict Mode, and specialized utilities like 'why-did-you-render'.

Developer Tools

Diagnoses and resolves complex React errors including infinite re-renders, stale hook closures, and hydration mismatches.

About

The React Debugging skill provides a systematic framework for identifying and fixing common and advanced issues in modern React 18/19 applications. It offers domain-specific guidance for troubleshooting functional components, state management loops, and hook-related bugs like stale closures or missing dependencies. By leveraging proven resolution patterns for memory leaks, key prop warnings, and SSR hydration errors, this skill helps developers build more resilient frontend architectures and optimize application performance.

Key Features

Detect and prevent memory leaks in useEffect cleanup functions
Resolve stale closures and dependency issues in React Hooks
Optimize component performance through strategic re-render isolation
Debug SSR/SSG hydration mismatches in modern frameworks
Identify and fix 'Too many re-renders' and infinite state loops
0 GitHub stars

Use Cases

Eliminating performance bottlenecks identified by the React DevTools Profiler
Troubleshooting 'Cannot read property of undefined' errors in data-heavy components
Fixing inconsistent UI behavior caused by incorrect hook usage or stale state
