Answer 1

Here is a good solution suitable for append-only data: https://habr.com/post/423737/ https://habr.com/post/424415/
instead of a backend - statics into which data is added by some service, frontend requests data with content-range. It is very fast, simple and reliable, and it can work without a server part, especially if the hosting has ssh, through which the statics can be updated. And on the client, setInterval or setTimeout, it doesn't matter.
