# `@effect-view/vite`

Experimental Vite Fast Refresh support for Effect View components.

```ts
import effectViewRefresh from "@effect-view/vite"
import react from "@vitejs/plugin-react"
import { defineConfig } from "vite"

export default defineConfig({
    plugins: [
        effectViewRefresh(),
        react(),
    ],
})
```

The plugin recognizes `Component.make` and `Component.makeUntraced`
definitions imported from `effect-fc-next`. The legacy `effect-fc` package is
not supported. `effect-fc-next` owns the bundler-neutral refresh cell protocol;
this package is the Vite adapter that retains those cells in HMR data. The
plugin assigns stable development IDs and self-accepts successfully
instrumented modules.

The adapter-facing protocol is exported from `effect-fc-next/Refreshable`.

Renaming or removing an instrumented View invalidates the module upward instead
of leaving a stale mounted descriptor.

React state is retained when the ordered hook signature is unchanged. Adding,
removing, or changing a hook call resets the Effect View implementation. Add
`// @refresh reset` to a module to reset its Views on every update.

## Current limitations

- Vite is the only supported bundler.
- Definitions must be top-level variable, class, or default-export
  declarations.
- Hook signature analysis is conservative and based on `useX` call syntax.
- Changing a descriptor's trait pipeline during a refresh is not guaranteed to
  preserve state.
- Source maps for the injected transform are not generated yet.
