What is SPA usually given to?

Question

Nginx

There is a client application (spa), now it is being served using a server on the node.js platform. Out of the corner of my eye I see nginx flashing for these purposes, why is it better for these purposes or can there be something even better? And even when uploading to PaaS, both the dev and prod versions are uploaded, i.e. and build all the same on the hosting, and not just given the finished build?

Answer 1

Easier middleware configuration DDoS protection, scaling.
If the service is small, then most often nginx is superfluous there
