* Expose LegacyHidden type I will use this internally at Facebook to migrate away from <div hidden />. The end goal is to migrate to the Offscreen type, but that has different semantics. This is an incremental step. * Disable <div hidden /> API in new fork Migrates to the unstable_LegacyHidden type instead. The old fork does not support the new component type, so I updated the tests to use an indirection that picks the correct API. I will remove this once the LegacyHidden (and/or Offscreen) type has landed in both implementations. * Add gated warning for `<div hidden />` API Only exists so we can detect callers in www and migrate them to the new API. Should not visible to anyone outside React Core team.

This package implements the wiring necessary to integrate Fast Refresh into bundlers. Fast Refresh is a feature that lets you edit React components in a running application without losing their state. It is similar to an old feature known as "hot reloading", but Fast Refresh is more reliable and officially supported by React.
This package is primarily aimed at developers of bundler plugins. If you’re working on one, here is a rough guide for Fast Refresh integration using this package.
