experiment with ssr hmr

[hi-ogawa]

todo

• polish transform
• explore proxy approach
• allow customizing accept condition (e.g. full reload if there is non-component export)
• package (move to feat: create vite-plugin-simple-hmr vite-plugins#157)

notes

Still hydration error when

• edit AppDep.tsx
• edit App.tsx
• edit AppDep.tsx
• reload

Maybe App.tsx is importing something different from AppDep.tsx's registry.activeExports at some point.

To fix this, we either need to:

• replace all the exports of the entire hot update history
  • simple but this would leak memory indefinitely until full-reload d1f9d9d
    • should try hot.prune? https://vitejs.dev/guide/api-hmr.html#hot-prune-cb
• or wrap/proxy each export so that "reader" side can always reference the latest module
  • probably more logic is required for transform/runtime for proxy system. also it might pollute stacktrace when original function is throwing?
