I'm not a fan of adding examples for literally every web framework/library under the sun. If we add actix-web, we might as well also add axum, rocket, etc. Is warp not good enough? Also, tide (with surf) shouldn't be used. They're based on async-std and Yew uses tokio spawn_local internally.

I would like to hold this PR off until #2453 is merged (that's why I added the blocked label)

If we're gonna collect backend examples I think we should clearly separate them from the other examples, perhaps even in a different repository.

I would vote not to have this example as well. As that puts more work on us, maintainers.

Better approach would be to have this example in your own repo and just link to it in our docs somewhere here https://yew.rs/community/awesome

Closing as 2 out of 3 maintainers agree this should not be part of yew.
