Example

This codemod turns X into Y. It also does Z. Note: this is a contrived example. Please modify it.

This codemod migrates useHistory to useNavigate in React Router codebases. It replaces useHistory imports and updates all instances of history.push, history.replace, go, goBack, and goForward to align with the useNavigate API.

This codemod updates Switch components to Routes in React Router, in line with React Router v6 and newer. It also adjusts the imports, replacing Switch with Routes in react-router-dom import statements.

This codemod updates imports of StaticRouter to use the react-router-dom/server package instead of react-router-dom, in line with updated React Router requirements.

This codemod simplifies the Link component by transforming its to prop from an object with a pathname to a string. It removes the unnecessary object wrapper around the pathname, maintaining the state prop as is.

This codemod updates useRouteMatch calls to the newer useMatch function in react-router-dom. It also adjusts any arguments passed to useRouteMatch, changing strict to end and sensitive to caseSensitive. Additionally, it ensures that imports are updated to reflect the removal of useRouteMatch.

This codemod reorders the arguments in the matchPath function calls. It switches the position of the string path and the second callback argument, improving consistency and readability.

This codemod updates NavLink components that use separate style and activeStyle props to the modern isActive function in react-router-dom. It simplifies the logic by combining the two props into a single style prop with conditional styling.

This codemod modernizes Route and Link components in React Router by:

1. Removing the deprecated exact prop from Route.
2. Updating Route to use the element prop.
3. Rewriting dynamic Link and Route paths that use template literals like ${match.url} and ${match.path}.

This codemod updates deprecated Redirect components from react-router-dom to the modern Navigate API. It also updates the imports by replacing Redirect with Navigate.

This codemod helps update code that uses react-router-config to the modern useRoutes API from react-router-dom. It removes renderRoutes from imports and replaces it with useRoutes. Manual adjustments might be required after running the codemod, especially if other customizations exist in your routing logic.

This codemod replaces the deprecated exact prop in NavLink with the modern end prop. React Router v6 and beyond use end to indicate that the path should match exactly, making this a necessary update for compatibility with newer versions.

This codemod transforms Route components using render and component props into JSX with nested children.

Theme tools has been removed, so this codemod transforms it, to use CSS color mix.

• Updates the ChakraProvider import from @chakra-ui/react
• Renames the theme prop to value to match the new system-based theming approach

• Replaces extendTheme with createSystem and defaultConfig.
• Updates your theme object to fit the new structure required by Chakra UI.

In v7 the react-router and react-router-dom packages are combined so this codemod import everything directly from "react-router" except for the RouterProvider exception.

Handles the migration of the CssExtractWebpackPlugin webpack plug-in into an included plugin in rspack.

• Rspack has implemented most of webpack's built-in plugins, with the same names and configuration parameters, allowing for easy replacement.
• Replace the the include package from webpack to rspack one.
• Replaces the webpack object in the plugins array to rspack object.
• Handles only for supported and partially supported built-in plugins. (as of 11th Oct 2024)

Using builtin:swc-loader offers better performance compared to the babel-loader and the external swc-loader, as it avoids frequent communication between JavaScript and Rust.
