Cleanup on vite restart.

[olafurw]

Description

There can be many situations when you need to clean up or release a resource when a vite instance restarts, like after a config edit. You might have to close a db connection, there might be files that need to be cleared or reset, etc.

But if you have something like vite dev running and you connect to a database and then change a file that causes a service restart, the connection stays open in the background.

Suggested solution

If there would be some signal sent that could be intercepted to tell us that a restart was going to happen, that would be enough.

A very rough idea is something like, there can be other ways, just something to help us react to this restart if we need.

process.on('vite-restart', () => {
  // ...
});

You can use a Vite plugin and the buildEnd hook to cleanup on restart, or if it's in the SSR runtime, you can watch #7887
