- Vercel Postgres To Neon- This is a codemod created with - codemod init.
- Sveltekit Vite Preprocess Migration- This codemod updates import paths and ensures compatibility with changes in library structures. In this example, it modifies the import statement for vitePreprocess to reflect updates in the library's API. 
- Sveltekit Import And Path Simplification- This codemod simplifies the import statements and path resolution in your SvelteKit project. It replaces the usage of - resolvePathand concatenation with- baseby using the- resolveRoutefunction from- $app/paths. This results in cleaner and more readable code.
- Goto To Location Href- Codemod Description- This codemod is designed to replace specific patterns in TypeScript files with updated code logic. It transforms instances of - goto($A)into- window.location.href = $A;when the- $Avalue is a URL starting with- http://or- https://. This refactor makes external navigation more explicit by using- window.location.href.
- Dynamic To Static Env Transformer- This codemod transforms import {$A} from '$env/dynamic/public'; and import {$A} from '$env/dynamic/private'; into their static counterparts, replacing them with import {$A} from '$env/static/public'; and import {$A} from '$env/static/private';, respectively. It ensures compatibility for prerendered pages and static deployments. 
- Add Status To Error Handling- This codemod improves error handling in SvelteKit by updating the way errors are returned in the load function. In SvelteKit 1, errors were handled inconsistently, often missing the status property or failing to trigger the handleError hook. SvelteKit 2 standardizes error handling by automatically including the status and message properties in error responses. 
- Add Multipart Enctype To Forms With File Input- This codemod automatically adds the enctype="multipart/form-data" attribute to forms containing file input fields. It ensures that forms with file inputs properly handle file uploads during non-JS submissions, which is a requirement for SvelteKit v2. 
- Add Cookie Path To All Methods- This codemod adds - { path: '/' }to all- cookiesmethod calls in your TypeScript project. It ensures that cookies are set, deleted, or serialized with the correct path specified, which helps in consistent cookie handling across different environments.
- Replace Throw With Error Call- This codemod simplifies error handling and redirects in your TypeScript project by replacing - throw error()and- throw redirect()statements with direct calls to- error()and- redirect(). This change aligns with modern practices and results in cleaner, more readable code.
- React 17 Default Props To Params- This codemod turns X into Y. It also does Z. Note: this is a contrived example. Please modify it. 
- React Router/5.1/Redirect To Navigate- This codemod updates deprecated - Redirectcomponents from- react-router-domto the modern- NavigateAPI. It also updates the imports by replacing- Redirectwith- Navigate.
- React Router/5.1/Component Render To Children- This codemod transforms - Routecomponents using- renderand- componentprops into JSX with nested children.
- ChakraUI/V3/Remove Theme Tools- Theme tools has been removed, so this codemod transforms it, to use CSS color mix. 
- ChakraUI/V3/Update Chakra Provider- Updates the ChakraProvider import from @chakra-ui/react
- Renames the theme prop to value to match the new system-based theming approach
 
- ChakraUI/V3/Refactor Custom Theme- Replaces extendTheme with createSystem and defaultConfig.
- Updates your theme object to fit the new structure required by Chakra UI.
 
- Webpack To Rspack/Remove Raw Loader To Type Asset Source- Rspack implements Webpack 5's Asset Modules, using asset modules to replace raw-loader to 'asset/source' for better performance. 
- Webpack To Rspack/Remove Url Loader To Type Asset Inline- Rspack implements Webpack 5's Asset Modules, using asset modules to replace url-loader to 'asset/inline' for better performance. 
- Webpack To Rspack/Remove File Loader To Type Asset Resource- Rspack implements Webpack 5's Asset Modules, using asset modules to replace file-loader to 'asset/resource' for better performance. 
- Webpack To Rspack/Migrate Update Babel Loader To Swc Loader- 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.
