SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires react, eslint-plugin-react-hooks, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill ensures React components and hooks adhere to best practices, optimizing performance and reducing bugs.

Core Features & Use Cases

  • Purity Enforcement: Ensures components and hooks are idempotent and have no side effects in render.
  • Immutability: Prevents direct mutation of props, state, and hook arguments.
  • React Controls Rendering: Enforces correct usage of components and hooks, preventing direct calls and improper prop passing.
  • Rules of Hooks: Guides on hook usage, including calling hooks at the top level and from React functions.
  • Use Case: When writing or reviewing React components, custom hooks, or debugging memoization issues.

Quick Start

Use the react skill to check the purity of a React component named 'MyComponent'.

FAQPage Schema
How do I enforce React best practices for component purity and immutability?

To enforce React best practices for component purity and immutability, you use linting rules that check for side effects in render and prevent direct mutation of props, state, or hook arguments. This ensures components remain idempotent.

How do I check if a React component violates the Rules of Hooks?

You can check if a React component violates the Rules of Hooks by applying linting rules that enforce calling hooks at the top level and only from within React functions, preventing conditional or nested hook calls that break state management.

Why does my React component have memoization issues and side effects in render?

React memoization issues and side effects in render typically occur when components lack purity, directly mutate state, or violate rendering controls, which can be detected by enforcing strict immutability and idempotency rules during code review.

Do I need ESLint to enforce React performance optimization rules?

Yes, you need ESLint configured with the appropriate React hooks plugin to enforce React performance optimization rules, as it provides the linting framework required to automatically detect and flag incorrect hook usage and impure components.

What is the best way to prevent direct mutation of props and state in React?

The best way to prevent direct mutation of props and state in React is by applying immutability enforcement rules that restrict improper prop passing and direct state mutation, ensuring React maintains control over the rendering process.

Can I use React linting rules to debug custom hooks for correct usage?

Yes, you can use React linting rules to debug custom hooks for correct usage by enforcing the Rules of Hooks, which verifies that hooks are called at the top level and from React functions, optimizing performance and reducing bugs.
