Migrating To Sveltekit V2

# SvelteKit v2 Migration Codemods

This repository contains a collection of codemods to assist in migrating projects to SvelteKit v2. Each codemod targets specific areas of code that need updating, making the migration process smoother and more efficient.

Available Codemods

1. Add Cookie Path to All Methods (add-cookie-path-to-all-methods)

   Adds { path: '/' } to all cookies method calls (set, delete, serialize) to ensure consistent cookie handling across different environments.

2. Add Multipart Enctype to Forms with File Input (add-multipart-enctype-to-forms-with-file-input)

   Automatically adds enctype="multipart/form-data" to <form> elements that contain <input type="file">, ensuring file uploads work correctly.

3. Add Status to Error Handling (add-status-to-error-handling)

   Enhances error handling by adding appropriate status codes where missing, improving clarity and HTTP response correctness.

4. Dynamic to Static Env Transformer (DynamicToStaticEnvTransformer)

   Converts dynamic environment variables to their static equivalents, aiding in the transition to the new environment variable handling in SvelteKit v2.

5. Goto to Location Href (goto-to-location-href)

   Replaces uses of goto() with location.href to align with the updated navigation practices in SvelteKit v2.

6. Replace Throw Statements with Direct Function Calls (replace-throw-redirect-with-error-call)

   Simplifies error handling and redirects by replacing throw error() and throw redirect() statements with direct calls to error() and redirect().

7. SvelteKit Import and Path Simplification (sveltekit-import-and-path-simplification)

   Simplifies import statements and path resolution by replacing resolvePath and base concatenations with resolveRoute from $app/paths.

8. SvelteKit Vite Preprocess Migration (sveltekit-vitePreprocess-migration)

   Updates the preprocessing setup to use vitePreprocess in line with SvelteKit v2's recommended practices.

Usage

To use any of these codemods, navigate into the desired codemod's directory and follow the instructions provided in its README.md. Ensure that you have the necessary dependencies installed and that your project is properly configured to apply the codemods.

Example

To run the transform scripts use codemod command below:

$ npx codemod <transform> --target <path> [...options]

transform: name of transform, see available transforms below.

path: directory to transform. defaults to the current directory.

See the codemod CLI doc for a full list of available commands. All codemods are also available in the Codemod Registry.
