This npm package is reserved for advanced users who want to decouple their JavaScript dependencies from their PHP dependencies (e.g., when building Docker images, running JavaScript-only pipelines, etc.).

We strongly recommend not installing this package directly, but instead install the PHP package symfony/ux-svelte in your Symfony application with Flex enabled.

If you still want to install this package directly, please make sure its version exactly matches symfony/ux-svelte PHP package version:

composer require symfony/ux-svelte:2.23.0
npm add @symfony/ux-svelte@2.23.0

Tip: Your package.json file will be automatically modified by Flex when installing or upgrading a PHP package. To prevent this behavior, ensure to use at least Flex 1.22.0 or 2.5.0, and run composer config extra.symfony.flex.synchronize_package_json false.
