Known limitations

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

Introduction

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

Preact configuration

Use the React-facing package with `preact/compat` aliases and verify hooks or context-heavy usage in your app.

SSR notes

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

Islands notes

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