react-tooling

Configure debugging, bundle analysis, and ecosystem tools for React applications. Use when setting up Vite/webpack build tooling, analyzing bundle size, debugging re-renders with React DevTools, or configuring ESLint and StrictMode for React projects. (triggers: package.json, devtool, bundle, strict mode, profile)

Best use case

react-tooling is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Configure debugging, bundle analysis, and ecosystem tools for React applications. Use when setting up Vite/webpack build tooling, analyzing bundle size, debugging re-renders with React DevTools, or configuring ESLint and StrictMode for React projects. (triggers: package.json, devtool, bundle, strict mode, profile)

Teams using react-tooling should expect a more consistent output, faster repeated execution, less prompt rewriting.

When to use this skill

  • You want a reusable workflow that can be run more than once with consistent structure.

When not to use this skill

  • You only need a quick one-off answer and do not need a reusable workflow.
  • You cannot install or maintain the underlying files, dependencies, or repository context.

# React Tooling

## **Priority: P2 (OPTIONAL)**

Tools for analysis, debugging, and build optimization.

## Debugging Workflow

1. **Enable StrictMode** to catch side-effect bugs during development.
2. **Profile** with React DevTools Flamegraph to identify expensive components.
3. **Trace re-renders** using "Highlight Updates" or `why-did-you-render`.
4. **Analyze bundle** with `source-map-explorer` or `rollup-plugin-visualizer` before shipping.

## Setup

See [implementation examples](references/example.md#strictmode--why-did-you-render-setup) for StrictMode, why-did-you-render, and custom hook debug label setup.

## Implementation Guidelines

- **Analysis**: Use `source-map-explorer` or `webpack-bundle-analyzer` / `rollup-plugin-visualizer` (Vite).
- **Linting**: Mandate `eslint-plugin-react-hooks` (exhaustive-deps) and Prettier.
- **Environment**: Use Vite over CRA. Manage environment variables with `.env`.
- **Build**: Configure Terser for production minification. Use `vite-plugin-pwa` for service workers.

## Anti-Patterns

- **No production profiling**: Remove `why-did-you-render` and debug tools before production builds.
- **No skipping StrictMode**: Keep `<React.StrictMode>` in dev to surface side effects early.
- **No CRA for new projects**: Use Vite for faster builds and better DX.
