Session is required for some authentication in the nodejs project. For example, the demo of the nodejs chat room I wrote is the authentication implemented through session. If a session exists, you can directly log on to the chat room without logging on again. I also found many session calling methods in the Express framework on the Internet, but I found that not many of them are actually usable. Today, based on the production process of the chat room, I sorted out Express and

The socket. Io official website uses express to implement the simplest im instant chat. Today we use Koa to implement it. ### Framework preparation Make sure that you have installed nodejs and NPM locally. Use Koa to require node version> 7.6 Create a folder (the official website name is chat-example) where you need it) Go to the project directory and create the package. JSON file: { "name": "

If a developer wants to completely control the sending of messages and events in a specific application, you only need to use a default "/" namespace. however, if developers need to provide applications to other applications as third-party services, they need to define an independent namespace for a

The socket. io client is very elegant in event processing, which is similar to weboscket's limited javascript interface, but supports more custom events: Var socket = io. connect ('HTTP: // localhost: 9000/chat '); Socket. on ('connect ', function (){// Your code here});
