Partytown

Third party scripts slow down your initial page load substantially by blocking the main thread.

Partytown is a tool that allows you to defer third party scripts like Google Analytics, Facebook Pixel, etc off the main thread by using a web worker. For more information about this tool visit the Partytown docs.

Usage

You can add Partytown easily by using the following Qwik starter script:

pnpm run qwik add partytown

npm run qwik add partytown

yarn run qwik add partytown

bun run qwik add partytown

The previous command updates your app and sets the correct configuration in vite.config.mts.

It also adds new files to your components folder.

src/root.tsx

import { QwikPartytown } from './components/partytown/partytown';
 
export default component$(() => {
  return (
    <QwikRouterProvider>
      <head>
        <meta charSet="utf-8" />
        <QwikPartytown forward={['gtag','dataLayer.push']} />
        <script
          async
          type="text/partytown"
          src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXX"
        />
        <script
          type="text/partytown"
          dangerouslySetInnerHTML={`
            window.dataLayer = window.dataLayer || [];
            window.gtag = function() {
              dataLayer.push(arguments);
            }
            gtag('js', new Date());
            gtag('config', 'G-XXXXXX');
          `}
        />
      </head>
      <body lang="en"></body>
    </QwikRouterProvider>
  );
});
