How do I handle mounting logic without useEffect?

The skill provides a 'useMountEffect' pattern for rare cases requiring external system synchronization, making the intent explicit and avoiding dependency array issues.

Why does this skill ban the use of useEffect?

While part of React, useEffect is frequently misused for state synchronization and data fetching, leading to race conditions and performance bottlenecks. This skill enforces more efficient alternatives recommended by the React core team.

What should I use instead of useEffect for data fetching?

This skill encourages the use of data-fetching libraries like TanStack Query or SWR, which handle caching, retries, and race conditions more reliably than manual effects.

Can this skill help with existing React bugs?

Yes, by refactoring useEffect-heavy code into derived state or event handlers, it often resolves issues related to stale props, infinite loops, and 'glitchy' UI updates.

Enforces modern React best practices by replacing problematic useEffect calls with efficient architectural patterns like derived state and event handlers.

The No-useEffect skill is a specialized guide for Claude Code that prevents the common pitfalls of overusing the useEffect hook in React applications. It guides the AI to prioritize idiomatic React patterns such as inline state derivation, event-driven actions, and key-based component resets, which leads to fewer re-renders and more predictable code. This skill is particularly useful during refactoring or when building new features to ensure your React codebase remains performant, readable, and free of race conditions often introduced by manual effect management.
