How does this skill help with performance?

It identifies 'render loops' caused by defining nodeTypes inside components and flags missing memoization on custom nodes that cause lag.

What version of React Flow does this skill support?

The skill is optimized for modern React Flow implementations, specifically targeting the @xyflow/react package and its current best practices.

Can it help fix invisible or broken flows?

Yes, it checks for common mistakes like missing container height, forgotten CSS imports, and incorrect provider nesting.

Does it support TypeScript-specific checks?

Absolutely. It provides guidance on using explicit generic types for nodes and edges to ensure full type safety across your graph.

设计工具

Reviews React Flow implementations to identify anti-patterns, optimize performance, and ensure best practices for node-based interfaces.

关于

This skill empowers Claude to perform deep technical audits of React Flow (xyflow) codebases, focusing on performance bottlenecks and common architectural errors. It specifically detects issues like unnecessary re-renders caused by missing memoization, incorrect provider placement, and inefficient state management. Whether you are building a complex graph editor or a simple workflow visualizer, this skill ensures your React Flow implementation remains fluid, type-safe, and maintainable by applying industry-standard optimization patterns and verification workflows.

主要功能

Identifies missing memoization hooks like memo, useCallback, and useMemo
Validates ReactFlowProvider scope and useReactFlow hook usage
Checks for essential CSS imports and proper container dimensioning
14 GitHub stars
Flags improper state mutations and complex object storage in node data
Detects performance-draining re-renders in node and edge components

使用场景

Automating architectural reviews for PRs involving complex diagramming features
Optimizing heavy node-based UIs that suffer from lag during canvas interactions
Debugging layout issues where flows are invisible or non-interactive
