Real-time Backend Libraries

Web backend real-time libraries are software packages that developers use to build real-time applications using WebSockets or other technologies. These libraries provide pre-built tools and functions to handle bi-directional communication between clients and servers and to transmit and receive data in real-time, without the need for frequent page refreshes. By using a real-time library, developers can create web applications that are responsive and interactive, with features such as chat rooms, live notifications, and collaborative editing. Real-time libraries can be integrated with popular web frameworks such as Socket.IO, Pusher, and PubNub, and can be customized to meet the specific needs of each application. Overall, real-time libraries are a valuable resource for developers building web applications that require real-time communication and collaboration.
