Overview

Upgrade @sveltejs/vite-plugin-svelte from v5.x to v6.x:

• @sveltejs/vite-plugin-svelte: ^5.0.3 → ^6.x

This plugin bridges SvelteKit / Svelte with Vite and must stay compatible with the Svelte, SvelteKit and Vite versions in use.

Notes

• May require Vite v7 (see linked Vite upgrade issue)
• Check @sveltejs/kit compatibility matrix

Required Work

1. Update package

npm install @sveltejs/vite-plugin-svelte@^6

2. Check compatibility

Ensure versions of svelte, @sveltejs/kit, and vite are all compatible with v6.

3. Testing Checklist

• npm run dev works with HMR
• npm run build completes successfully
• Svelte components compile correctly
• MDsveX still processes .svelte.md / .md files

Resources

• @sveltejs/vite-plugin-svelte releases

Priority

Low — depends on Vite v7 upgrade.
