Bug: The @sveltejs/vite-plugin-svelte dependency is pinned to version 1.4.0, which is incompatible with Svelte 5 and will cause build and test failures.
Severity: CRITICAL

Suggested Fix

Update the @sveltejs/vite-plugin-svelte dependency in packages/svelte/package.json from version 1.4.0 to a version compatible with Svelte 5, such as ^3.0.0.

valid.

Location: packages/svelte/package.json#L50

Potential issue: The `package.json` for the `svelte` package pins the
`@sveltejs/vite-plugin-svelte` dependency to version `1.4.0`. This version is
incompatible with the Svelte 5 upgrade in this pull request, which requires version
`^3.0.0` or higher. This mismatch will cause the build and test pipeline to fail when
the Vite configuration attempts to load the outdated plugin, preventing any tests from
running successfully. Other packages in the monorepo, such as `sveltekit`, already use a
compatible version of the plugin.

Did we get this right? 👍 / 👎 to inform future reviews.

Svelte 5 bump breaks incompatible vite plugin dependency

High Severity

Bumping svelte from 3.59.2 to 5.51.5 without updating @sveltejs/vite-plugin-svelte from 1.4.0 breaks the build and test pipeline. Version 1.4.0 only supports Svelte 3 (depends on svelte-hmr@^0.15.1) and is incompatible with Svelte 5's completely different compiler API. Similarly, @testing-library/svelte ^3.2.1 doesn't support Svelte 5 — tests using component.$set() will fail since Svelte 5 components are no longer class instances. Both companion dev dependencies need to be updated to Svelte 5–compatible versions.
