Uniquely identifying PWAs with the web app manifest id property
There's a new optional id property as part of the web app manifest spec, that allows you to explicitly define the identifier used for your PWA. Adding the id property to the manifest removes the dependency on the start_url or the location of the manifest, and makes it possible for them to be updated in the future.
