Because Some socket.io related client library are still support 0.9.x. (eg: Object-c library, Java library )
So I need to read document about 0.9.x, so I try to visit
This above link is about 1.x version. and the github wiki is not work.
path Default value: /socket.io/ It is the name of the path that is captured on the server side.
You can check the socket.io version in node_modules->socket.io->package. json and there will be "version": "your version of socket.io".
You can check the socket. connected property: var socket = io. connect(); console.
Socket.IO allows bi-directional communication between client and server. Bi-directional communications are enabled when a client has Socket.IO in the browser, and a server has also integrated the Socket.IO package. While data can be sent in a number of forms, JSON is the simplest.
Socket.io still have parts of the documentation in their readme if you change to the 0.9.x tags/branch.
