As per the official guidelines, I attempted to create a PWA that functions in offline mode using pure PWA without angular-cli.
However, despite following the official instructions, I was unable to make it work offline. The document in question can be found here: https://angular.io/guide/service-worker-getting-started#getting-started-with-service-workers
My angular-cli version is @angular/[email protected]
You can view my code at https://github.com/unnhao/pwa-test
To resolve the issue, consider manually registering the service worker. Within your src/main.ts file, make the following adjustment:
platformBrowserDynamic().bootstrapModule(AppModule)
.catch(err => console.error(err));
Replace it with the following code snippet:
platformBrowserDynamic().bootstrapModule(AppModule).then(() => {
if ('serviceWorker' in navigator && environment.production) {
navigator.serviceWorker.register('/ngsw-worker.js');
}
}).catch(err => console.log(err));
Please excuse any formatting issues, as this is my first formal response. I encountered the same problem and experimented with various solutions before finding success with this one. The initial source of this solution can be traced back to: https://github.com/angular/angular-cli/issues/13351
