tips for enabling communication between the server and client

As someone who is new to the world of web development, please bear with me as I ask a question out of curiosity.

I am wondering if there is a method for the server to push messages to clients. For instance, imagine a client's webpage featuring a newsfeed that automatically updates whenever a new story reaches the server. Instead of having the client continually send requests to check for updates every few seconds, I envision a scenario where the server initiates communication with the client, prompting it to update its newsfeed accordingly without any active involvement from the client. Is this type of functionality possible?

Does such a solution exist?

javascript client-server

Answer №1

Modern browsers offer the option to establish a continuous connection with a server using web sockets, allowing for seamless communication between client and server.

On the other hand, older browsers rely on a method known as "polling" to check for new messages from the server. The client regularly queries the server for updates, either through traditional polling every 60 seconds or through a longer poll where the server holds the request until new data is available. Comet is an example of a library that simplifies the implementation of long polling techniques.
