Support for vite-plugin-pwa (Workbox) with wxt – Merging with background.ts Service Worker

[pooooriya]

Hi everyone 👋

I'm trying to add offline support to my browser extension using vite-plugin-pwa, which uses Workbox under the hood. However, I'm running into an issue with wxt.

In a typical wxt setup, the background.ts file is registered as a service worker. But since vite-plugin-pwa also generates a sw.js, I'm not sure how to merge the two properly. I haven't found any good examples for this use case.

Has anyone successfully integrated vite-plugin-pwa with wxt? Is it even possible to combine the Workbox-generated sw.js with the background.ts service worker? I’d love to handle offline functionality through Workbox while keeping the background script intact.

Any guidance, examples, or suggestions would be greatly appreciated! 🙏
