unload eventSocket.IO is a library that enables real-time, bidirectional and event-based communication between web clients and servers. It is built on top of WebSockets and provides additional features such as fallback to HTTP long-polling, automatic reconnection, and rooms/namespaces. Compared to Faye, Socket.IO offers more advanced features and is widely used for real-time applications.
Primus is a flexible and extensible library for real-time communication. It abstracts various real-time frameworks (including WebSockets, Engine.IO, and SockJS) and provides a unified API. Primus allows developers to switch between different real-time frameworks without changing the application code. Compared to Faye, Primus offers more flexibility in terms of underlying transport mechanisms.
Pusher is a hosted service that provides real-time messaging and event broadcasting. It offers a simple API for sending and receiving messages and supports various client libraries for different platforms. Pusher is a managed service, which means developers do not need to set up and maintain their own servers. Compared to Faye, Pusher is easier to set up but comes with a cost for the managed service.
