node.js - 微信小程序有自己的ws协议，用nodejs的话，还需要nginx干嘛呢

Question

用express的话，这里的nginx能发挥什么作用呢，是否可以不用nginx

Answer 1

nginx can do load balancing, offloading, static server, proxy, redirection and other functions. In fact, it is just like the general PHP architecture, with nginx in the front and PHP in the back. Each has its own strengths and needs.
