Socket.IO

问题 Let me explain my setup.

问题 I have a socket.io server on my node.js API. When the node.js server is doing nothing, the latency of pong event is usually 5-10 milliseconds. However, when the node.js server is processing some very complex http request, the latency jumps to more than 100 or even over 5000 causing ping timeout . I am curious about what is effecting the latency? And, our framework requires a stable socket connection to send infos of a long http request to same socket as the request was made. How can we make

问题 I need to access Web sockets via specific path, I mount my socket.io on the client with a path ('ws') Server code: var io = require('socket.io')(server, {path: '/notif'}); Client code: var socket = io('//127.0.0.1:7733/ws/', {path: '/notif'}); socket.connect(); This does not work due to “ws” on client. I suspect it's because I don't have the equivalent on the server (e.g. require server on specific path). (when removing the /rt mount, everything seems to work as expected). What is the server
