How to check program running status in Node.js background

Node.js is a popular server-side development language with powerful backend capabilities. During the development process, we often need to watch the program running in the background so that we can debug and fix it in time when errors occur. This article will introduce how to implement this function in the Node.js backend. ## What is watching the running status of the program in the background? Watching the running status of the program in the background refers to outputting the running status of the program in text form on the terminal or command line interface when the program is running. This allows you to easily view the program's process, status, and log information, and find errors in a timely manner.

How to implement long connection in nodejs

Node.js is a very popular server-side JavaScript runtime environment. It excels in network programming, especially in implementing long-lived connections. In network programming, a long connection refers to a state in which the client and server maintain heartbeat activity and do not close the connection. Compared with the traditional HTTP request-response model, long connections can improve network efficiency and system performance. For example, when sending and receiving data through a long connection between the client and the server, the overhead of connection establishment and disconnection can be reduced, and the resulting network delay and system resource waste can be avoided.
