## 설명

This plugin offloads JavaScript execution to a Web Worker, improving performance
by freeing up the main thread. This should translate into improved [Interaction to Next Paint](https://web.dev/articles/inp)(
INP) scores.

⚠ _This functionality is experimental, and **it is now [intended to be sunset](https://github.com/WordPress/performance/issues/2284)**._
⚠

In order to opt in a script to be loaded in a worker, simply add `worker` script
data to a registered script. For example,
 if you have a script registered with 
the handle of `foo`, opt-in to offload it to a web worker by doing:

    ```
    wp_script_add_data( 'foo', 'worker', true );
    ```

Unlike with the script loading strategies (async/defer), any inline before/after
scripts associated with the worker-offloaded registered script will also be offloaded
to the worker, whereas with the script strategies an inline after script would block
the script from being delayed.

Otherwise, the plugin currently ships with built-in integrations to offload Google
Analytics to a web worker for the following plugin:

 * [Rank Math SEO](https://wordpress.org/plugins/seo-by-rank-math/)
 * [Site Kit by Google](https://wordpress.org/plugins/google-site-kit/)
 * [WooCommerce](https://wordpress.org/plugins/woocommerce/)

Please monitor your analytics once activating to ensure all the expected events 
are being logged. At the same time, monitor your INP scores to check for improvement.

This plugin relies on the [Partytown 🎉](https://partytown.builder.io/) library 
by Builder.io, released under the MIT license. This library is in beta and there
are quite a few [open bugs](https://github.com/BuilderIO/partytown/issues?q=is%3Aopen+is%3Aissue+label%3Abug).

The [Partytown configuration](https://partytown.builder.io/configuration) can be
modified via the `plwwo_configuration` filter. For example:

    ```
    <?php
    add_filter( 'plwwo_configuration', function ( $config ) {
        $config['mainWindowAccessors'][] = 'wp'; // Make the wp global available in the worker (e.g. wp.i18n and wp.hooks).
        return $config;
    } );
    ```

However, not all of the configuration options can be serialized to JSON in this 
way, for example the `resolveUrl` configuration is a function. To specify this, 
you can add an inline script as follows.

    ```
    <?php
    add_action(
        'wp_enqueue_scripts',
        function () {
            wp_add_inline_script(
                'web-worker-offloading',
                <<<JS
                window.partytown = {
                    ...(window.partytown || {}),
                    resolveUrl: (url, location, type) => {
                        if (type === 'script') {
                            const proxyUrl = new URL('https://my-reverse-proxy.example.com/');
                            proxyUrl.searchParams.append('url', url.href);
                            return proxyUrl;
                        }
                        return url;
                    },
                };
                JS,
                'before'
            );
        }
    );
    ```

There are also many configuration options which are not documented, so refer to 
the [TypeScript definitions](https://github.com/BuilderIO/partytown/blob/b292a14047a0c12ca05ba97df1833935d42fdb66/src/lib/types.ts#L393-L548).

## FAQ

### Why are my offloaded scripts not working and I see a 404 error in the console for `partytown-sandbox-sw.html`?

If you find that your offloaded scripts aren’t working while also seeing a 404 error
in the console for a file at `/wp-content/plugins/web-worker-offloading/build/partytown-
sandbox-sw.html?1727389399791` then it’s likely you have Chrome DevTools open with
the “Bypass for Network” toggle enabled in the Application panel.

thank you, this is amazing. i had problem with google tag manager and analytics.
i used this + site kit plugin and my performance went from 70 to 99. if you wanna
setup tag manager/analytics manually, you should add type=”text/partytown” to the
script tag. like: <script type=”text/partytown”> tag manager code </script> and 
it works like a charm!

Problems with Google Analytics and Google Tag ManagerTested: 1 week. While Enabled:
No hits, no recorded live users/users in Google Analytics. Google Tag Manager also
didnt get to connect to the site. – Clarity did record users live, and page hits.
This is because Clarity is not included in the built-in integrationWhile disabled:
Google Analytics got hits right away – same with Google Tag Manager.
