Other packages similar to socket.io-adapter
socket.io-redis
This package is an adapter for Socket.IO that enables broadcasting of events to multiple servers. It uses Redis as a pub/sub mechanism, allowing for scaling applications by distributing the load across several nodes. Compared to socket.io-adapter, socket.io-redis is specifically designed for use with Redis to support multi-server setups.
socket.io-emitter
Socket.IO Emitter allows you to emit events to Socket.IO servers from non-Socket.IO processes (e.g., a script or a backend service). It's useful for integrating different parts of your system with your real-time components. Unlike socket.io-adapter, which is focused on managing rooms and namespaces within a Socket.IO server, socket.io-emitter is designed for emitting events from outside the Socket.IO server environment.
