# `@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.
