👨‍💻 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 work!

// 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, you can pass a bs object with your BrowserSync options in it:

// 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.

// 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 recommended to use since it updates your index.html file.
In preview, only the proxy mode is supported since it will not inject the snippet.

// 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',
        }
      }
    })
  ]
}

Note

For Astro users, this plugin does not work in preview mode because of overrides made by Astro.
