Can I have multiple service workers in my PWA?

Hi @DuCanhGH! From the docs, next-pwa supports the configuration of custom service workers. Is it possible to have multiple workers in the customWorkerSrc path? Or if it isn't, does the custom worker override the default service worker from workbox?

Thanks so much for the library.

You can only have one custom worker, but you can import modules into it. Also, you can use workboxOptions.swSrc to opt into InjectManifest and create your own service worker :)

@DuCanhGH Thanks! If I specify a custom worker, does that override the behaviors of the default workbox worker?

[DuCanhGH]

@kylereblora that custom worker is bundled and then imported into Workbox's service worker using importScripts. I don't know whether you can override its behaviour or not, though.

Got it, so I think this means that when using a custom worker, this is "appended" to the workbox's service worker.

@kylereblora yeah, that's pretty much it :)
