Oh, and uWSGI can expose anything it runs through FastCGI. My personal opinion is that web crowd (most of JavaScript programmers fall in here) just doesn't want to learn from anybody else. > Is there any benefit of doing it that way? Compared to running the tiny web application on 80/tcp? Sure: I can run more than one and I don't need root privileges for the application. Compared to running the application behind a reverse proxy? Ditto: it's virtually impossible to get the setup wrong, so it's easier in the long run. > How does it work with WebSockets? No idea. I don't develop web applications.
