Config for supplying own service worker file

I tried to understand the custom config options for pwa.config.js, but could not find a way to get the workbox options (particularly, which swSrc applied in my build.

the config file looks like this right now:

exports.workbox = {
    advanced: false, // alias
    injectManifest: false, // alias
    swSrc: './service_worker.js', // template; mode: InjectManifest
    navigateFallbackWhitelist: [/^(?!\/__).*/], // mode: GenerateSW
    navigateFallback: 'index.html', // mode: GenerateSW
    swDest: 'sw.js',
    exclude: [
      /\.git/,
      /\.map$/,
      /\.DS_Store/,
      /^manifest.*\.js(?:on)?$/,
      /\.gz(ip)?$/,
      /\.br$/
    ]
  }

thanks for any pointers!

Start with the repository's handling of pwa.config.js and the workbox configuration shown in the issue, then trace how swSrc and the service_worker.js path are consumed during a build. Done means the documented configuration can supply a custom service worker file and the resulting build uses it as expected.
