Where can I find examples of using the manifest V3 API?

Question

JavaScript

There are generally examples of using the manifest V3 API. And that in representation different changes and features are written. Specifically, I'm interested in remote use of javascript https://developer.chrome.com/docs/extensions/mv3/i... , configs and services

Answer 1

About the remote code, they write that, on the contrary, they cut this feature in v3. It is no longer possible to eval the left code, just like it is impossible to insert a script into a page with js that is not from the extension archive.
Configs and services... scroll below and you will see that this is a service-worker API
In particular, configs, well... there are a lot of switches in large extensions and they do something, everything works - you can't/unpaid. Therefore, the config (previously - a piece of code) is downloaded from a remote server and the extension itself is partially/completely enabled.
