Angular 5 Service Worker not working - angular5

Question

I try to add service worker to my project after updating to angular 5 and have some problems. I add imports to app.module.ts:
import {ServiceWorkerModule} from '#angular/service-worker';
import {environment} from '../environments/environment';
...
environment.production ? ServiceWorkerModule.register('/ngsw-worker.js') : [],
execute $ ng set apps.0.serviceWorker=true to allow service workers in project
generate config:
{
"index": "/index.html",
"assetGroups": [
{
"name": "app",
"installMode": "prefetch",
"resources": {
"files": [
"/index.html"
],
"versionedFiles": [
"/*.bundle.css",
"/*.bundle.js",
"/*.chunk.js"
]
}
},
{
"name": "assets",
"installMode": "lazy",
"updateMode": "prefetch",
"resources": {
"files": [
"/assets/**"
]
}
}
],
"dataGroups": [
{
"name": "api-performance",
"urls": [
"/",
"/main",
"/login",
"/select-content"
],
"cacheConfig": {
"strategy": "performance",
"maxSize": 100,
"maxAge": "3d"
}
}
]
}
And manifest:
{
"name": "App",
"short_name": "App",
"start_url": "/login",
"theme_color": "#00a2e8",
"background_color": "#00a2e8",
"display": "standalone",
"icons": [
{
"src": "assets\/icons\/android-icon-36x36.png",
"sizes": "36x36",
"type": "image\/png",
"density": "0.75"
},
{
"src": "assets\/icons\/android-icon-48x48.png",
"sizes": "48x48",
"type": "image\/png",
"density": "1.0"
},
{
"src": "assets\/icons\/android-icon-72x72.png",
"sizes": "72x72",
"type": "image\/png",
"density": "1.5"
},
{
"src": "assets\/icons\/android-icon-96x96.png",
"sizes": "96x96",
"type": "image\/png",
"density": "2.0"
},
{
"src": "assets\/icons\/android-icon-144x144.png",
"sizes": "144x144",
"type": "image\/png",
"density": "3.0"
},
{
"src": "assets\/icons\/android-icon-192x192.png",
"sizes": "192x192",
"type": "image\/png",
"density": "4.0"
}
]
}
Then build it in production:
ng build --prod --aot=false --build-optimizer=false
Http-server run in SSL mode, but lsit of service workers in chrome dev-tools is clear. What's wrong? May be this flags broke it --aot=false --build-optimizer=false?

Seems to be a problem in registering service worker in module where also importing AngularFire2. I found solution how to register SW in main.ts, that's work:
platformBrowserDynamic().bootstrapModule(AppModule).then(() => {
if ('serviceWorker' in navigator && environment.production) {
navigator.serviceWorker.register('ngsw-worker.js');
}
}).catch(err => console.log(err));
