👨‍💻 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.
