@swc/plugin-prefresh

The SWC implementation of the prefresh babel plugin.

Usage

Prefresh babel plugin is a forked equivalent of the react-refresh babel plugin difference being that we need a way to memoize createContext between HMR.

And SWC has built-in React Refresh transformation, therefore, this plugin only implements the createContext processing part and need to be used with jsc.transform.react.refresh.
