How to make an offline copy of a web application page?

Question

Angular

With the traditional page generation approach, creating an offline copy is pretty straightforward.
There are a lot of programs for this business, and the browser can do this too.
But if we have a site running on the javascrip framework (angular, backbone, etc.), whose content is given in the form of json, and html is generated on the client side according to templates.
How to save such a page (site) for offline viewing?

Answer 1

caching http-proxy whichever you need. That would save the answers from the apishka. If your application is a cache on the client.
