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.
