Title: Web Worker Offloading Author: WordPress Performance Team Published: 2024 年 10 月 3 日 Last modified: 2026 年 2 月 27 日 --- 搜索插件 ![](https://ps.w.org/web-worker-offloading/assets/banner-772x250.png?rev=3173091) ![](https://ps.w.org/web-worker-offloading/assets/icon.svg?rev=3173091) # Web Worker Offloading 作者：[WordPress Performance Team](https://profiles.wordpress.org/performanceteam/) [下载](https://downloads.wordpress.org/plugin/web-worker-offloading.0.2.1.zip) * [详情](https://cn.wordpress.org/plugins/web-worker-offloading/#description) * [评价](https://cn.wordpress.org/plugins/web-worker-offloading/#reviews) * [开发进展](https://cn.wordpress.org/plugins/web-worker-offloading/#developers) [支持](https://wordpress.org/support/plugin/web-worker-offloading/) ## 描述 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: ``` { 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). ## 常见问题 ### 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. ### Where can I report security bugs?

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.
