Known limitations

  • PreactHub still needs project-specific verification notes for versions, bundle impact and edge cases.

Introduction

Preact Signals Core is tracked in PreactHub because it is relevant for Preact applications, migrations, ecosystem comparisons or adjacent tooling.

Preact configuration

No `preact/compat` alias is required for the primary API.

SSR notes

The library can participate in SSR-oriented workflows when browser-only APIs are guarded.

Islands notes

Preact Signals Core can be used from interactive islands as long as initialization is scoped to the island root and cleaned up when necessary.
