# pnpm
pnpm add -D vite-plugin-browser-sync

# bun
bun add -D vite-plugin-browser-sync
```

## 👨‍💻 Usage

By default, BrowserSync will start alongside your Vite Server in `dev`. It uses the `proxy` mode of BrowserSync based on your Vite server options : no need to pass any options to make it works!

```js
// vite.config.js / vite.config.ts
import VitePluginBrowserSync from 'vite-plugin-browser-sync'

export default {
plugins: [VitePluginBrowserSync()]
}
```

If you want to manage BrowserSync or [override default behavior of this plugin](https://github.com/Applelo/vite-plugin-browser-sync#vite-plugin-browser-sync-options-for-browsersync), you can pass a `bs` object with your [BrowserSync options](https://browsersync.io/docs/options) in it :

```js
// vite.config.js / vite.config.ts
import VitePluginBrowserSync from 'vite-plugin-browser-sync'

export default {
plugins: [
VitePluginBrowserSync({
dev: {
bs: {
ui: {
port: 8080
},
notify: false
}
}
})
]
}
```

If you need the `snippet` mode of BrowserSync, the plugin supports it by injecting the script automatically.

```js
// vite.config.js / vite.config.ts
import VitePluginBrowserSync from 'vite-plugin-browser-sync'

export default {
plugins: [
VitePluginBrowserSync({
dev: {
mode: 'snippet'
}
})
]
}
```

You can also enable the plugin on `vite build --watch` mode and `vite preview` mode.

> [!IMPORTANT]
> - In `buildWatch`, if you use the default `proxy` mode you need to set the `bs` object.
> - `snippet` mode is available in `buildWatch` but it is not recommanded to use since it update your `index.html` file.
> - In `preview`, only the `proxy` mode is supported since it will not inject the `snippet`.

```js
// vite.config.js / vite.config.ts
import VitePluginBrowserSync from 'vite-plugin-browser-sync'

export default {
plugins: [
VitePluginBrowserSync({
dev: {
enable: false,
},
preview: {
enable: true,
},
buildWatch: {
enable: true,
bs: {
proxy: 'http://localhost:3000',
}
}
})
]
}
```
