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.

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

Acerca de

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.

Características Principales
