Rari – Rust-powered React framework • Hacker News Board

I went through the website. But I do have a one question - it is not immediately clear to me why I'd use rari over Actix or just a plain-old Express server? What is "rust-powered performance"?

Fair point! To be clear: rari handled the traffic perfectly fine - the issue was an overly defensive rate limiter I had configured (and it was grouping proxy traffic incorrectly). The framework itself was cruising, I just had the safety rails set too tight. Adjusted now and it's handling the load as expected!

Is this like ReasonML and its React-Reason framework?

I don't really understand how it works, what part is Rust powered, is it reimplementing the JS engine in Rust?

I forgot all about Reason…
