2018年5月6日 · I'm not sure how "ngswConfigPath": "/src/ngsw-config.json", was added, but I removed it and it built fine. Next issue I faced was that ngsw-config.json has been moved out of src and to the project root during the upgrade. I had to copy my updates into the root ngsw-config.json for the service worker to register properly.

After a long search, we found out that the missing --prod flag in our build makes the problem. Exactly this one produces the service-worker files and no additional build flag is able to do it (same with uglifying and the uglifyer was the reason why we had exchanged the --build flag against --env=build earlier).

2020年7月23日 · What's happening is the service worker is trying to do a GET on the ngsw.json file using cache-busting, but it can't access it, because the app is offline. The fetch will fail and the call will look something similar to the following with a unique value: ngsw.json?ngsw-cache-bust=0.7064947087867681

In practice, the version is determined by the contents of the ngsw.json file, which includes hashes for all known content. If any of the cached files change, the file's hash will change in ngsw.json, causing the Angular service worker to treat the active set of files as a new version.

2020年7月22日 · Instead of adding the URL's manually, the URL's response should be stored dynamically when the user has searched for it when he was online. I mean i will initially not add any URL in list in the ngsw-config.json file, BUT when user has requested for that url, its response automatically get stored in cache.

2017年12月7日 · This has been made easier now, you can bypass URLs from angular service workers by using ngsw-bypass. From the docs: To bypass the service worker you can set ngsw-bypass as a request header, or as a query parameter. (The value of the header or query parameter is ignored and can be empty or omitted.)

i did some research and found that there is issue with /ngsw.json?ngsw-cache-bust=0.08769372894975769 GET request. though the fetchLatestManifest returns 200 status code,response is not actually JSON , instead its no script version of index.html. you can see response status is 200 for /ngsw.json?ngsw-cache-bust=0.08769372894975769

2021年2月3日 · That said, unfortunately, only the value of --base-href is included in paths that get generated within the ngsw.json file. This is a problem with Angular CLI and so far hasn't been addressed. A workaround is to run the ngsw-config command providing it with base href parameter as the last parameter/option. For example, what you could do is

2019年4月3日 · When I build the Angular project for the first time, run it in an incognito Chrome browser, my logs say that the ngsw-worker.js was retrieved successfully (GET) with http-server. When I remove the service worker in the dev tools, open up a new incognito tab (or close the browser and open a new incognito window), there is no ngsw-worker.js ...

In an Angular (8) app I'd like to add a custom offline page (just a plain simple html-file to begin with). I have set up my app as a PWA (using @angular/pwa and configured everything so that it at...
