Read about service-worker on the Angular site. The FR service-worker version should be preferred if your browser can use it. The service-worker technology is used to use cached static resources, so that the application can be used offline.
You could work with me on a real world variation of FR or similar application. As an admin, you would need to come up with a decision about where to store data, how to interconnect clients, and how to secure transport. I may have an opinion and a suggestion about how to do this, as long as you play it safe within your local area network.
