HMR for Stimulus controllers in Vite.js
The modified controller will be re-registered, so existing instances of it will `disconnect`, and new instances will be created and `connect`ed with the updated code.
## Installation 💿
HMR comes installed by default in [Jumpstart Rails with Vite.js][jumpstart],
a starter template that you can use to start your next Rails app.
If installing manually:
```bash
npx ni vite-plugin-stimulus-hmr
```
## Usage 🚀
Add it to your plugins in `vite.config.js`
```ts
// vite.config.js
import StimulusHMR from 'vite-plugin-stimulus-hmr'
export default {
plugins: [
StimulusHMR(),
],
};
```
You should now enjoy HMR for your Stimulus controllers! 🚀
## How does it work? 🤔
In order to simplify integration, the plugin will try to automatically detect when you define your Stimulus app, as in:
```js
const app = Application.start()
```
It will then detect any controller files using the Stimulus conventions, and inject an HMR `accept` call that re-registers the updated controller.
Just as when you use Turbolinks, it's important that your controllers are [idempotent].
