Warning

Deprecated: This package has been deprecated in 2.x and will be removed in the next major version.

Because it was not possible to add support for Svelte 5 in Symfony UX Svelte 3.0 for AssetMapper or even Webpack Encore (even by resorting to certain workarounds), and also due to its lack of popularity compared to Symfony UX React or Symfony UX Vue, the package is now deprecated and will be removed in Symfony UX 3.0.

See related issues and PRs: #2887, #2288, #3177.

But if you are brave enough and would like to recreate the package with support for Svelte 5 in Symfony UX 3.0, with support for AssetMapper and Webpack Encore, and without hacks, that would be greatly appreciated 😉

Symfony UX Svelte integrates Svelte into Symfony applications. It provides tools to render Svelte 3 or 4 components from Twig.
