Yes, Nginx can be a perfect gateway for http requests. Then what about SSH2, TNS(Oracle), TDS(SQL Server),...? Oh you got stream module. It's not naturally designed for human programmer and it's far from enough. Here is a library trying to solve these problems and it's easy to use.
I'm joey, a programmer from China, this is my first opensource project. I'm not really familiar with all those things, hope Dev and hacktoberfest can help me find some guy who share the same interests with me.
