Building an angular app with service-worker for using in sub-directory

Is there a way to build an angular app, so it works in multiple sub-directory like:

example.com/customerOne/  
example.com/customerTwo/  
example.com/customerThree/

If I just use ng build --prod the service-worker wants to fetch the files from example.com when the users is offline.

My index.html uses 

<base href="./" />

ServiceWorkerModule is registered as follow: 

    ServiceWorkerModule.register('./ngsw-worker.js', { enabled: environment.production  })

If possible I dont want to build for each customer, or use scope service worker.
Is it even possible?

Update

I tried now different configs for building:

ng build --prod --base-href ./ --deploy-url ./

it looks like it generates a ngsw.json file that should work?! but unfortunately when going offline it does not work.

I stooped using @ngular/serviceworker because i couldn't make it running.

Instead I'm using workbox.

Config:

module.exports = {
   globDirectory: 'www',
   globPatterns: ['**/*.{css,html,js,json,png,jpg,jpeg,svg,ico}'],
   swDest: 'www\\sw.js',
   swSrc: 'src\\sw.js',
   maximumFileSizeToCacheInBytes: 28 * 1024 * 1024
};

sw.js:

importScripts('https://storage.googleapis.com/workbox-cdn/releases/4.3.1/workbox-sw.js');

workbox.setConfig({
    debug: false
});

self.addEventListener('message', function (event) {
    if (event.data.action === 'skipWaiting') {
        self.skipWaiting();
    }
});

if (workbox) {
    console.log(`Yay! Workbox is loaded `);

    workbox.precaching.precacheAndRoute([]);
} else {
    console.log(`Boo! Workbox didn't load `);
}

and for building:

workbox injectManifest

this works out of the box
