Answer
Reverse proxies like Nginx handle SSL, caching, and load balancing. Node apps use them for better security and performance.
Quick Answer
A reverse proxy (nginx, Caddy) sits in front of Node.js and handles TLS termination, load balancing across multiple Node instances, serving static files, rate limiting, and HTTP/2. Node.js handles the application logic. This separation is standard practice — nginx is much better at serving static files and handling TLS than Node.js.
