Plus, if you're building a backend for a webapp, TS allows your engineers to build full-stack features in the same language, avoiding context-switching, code duplication, and other overhead.
Plus it’s a binary I can drop anywhere, will always be backwards compatible, no updated dependency is going to break it, I’m a fan of Go.
Other than Fiber, the techempower composite framework benchmark[0] ranks gin (go), nodejs, clevergo, and fastify (node) one after the other, all scoring right around 1600.
To be fair, Express is half that good at ~800, but upgrading from express to fastify should be fairly straightforward for those seeking better performance; the much newer fastify has a similar (often compatible) API.
For comparison, Python's fastapi is only 1200, and Django/Rails a mere 250, so lumping Node in with Python and Ruby doesn't make much sense; it'll often perform an order of magnitude better.
For computation-heavy workloads, multiprocessing with Node remains a challenge; Go's a more clear winner there.
