Depends on: - #28317 - #28320 --- Changes the behavior of the JSX runtime to pass through `ref` as a normal prop, rather than plucking it from the props object and storing on the element. This is a breaking change since it changes the type of the receiving component. However, most code is unaffected since it's unlikely that a component would have attempted to access a `ref` prop, since it was not possible to get a reference to one. `forwardRef` _will_ still pluck `ref` from the props object, though, since it's extremely common for users to spread the props object onto the inner component and pass `ref` as a differently named prop. This is for maximum compatibility with existing code — the real impact of this change is that `forwardRef` is no longer required. Currently, refs are resolved during child reconciliation and stored on the fiber. As a result of this change, we can move ref resolution to happen only much later, and only for components that actually use them. Then we can remove the `ref` field from the Fiber type. I have not yet done that in this step, though.
react-refresh
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.
