What is SocketCluster?

SocketCluster is a fast, highly scalable HTTP + realtime server engine which lets you build multi-process realtime servers that make use of all CPU cores on a machine/instance. It removes the limitations of having to run your Node.js server as a single thread and makes your backend resilient by automatically recovering from worker crashes and aggregating errors into a central log.
SocketCluster is a tool in the Realtime Backend / API category of a tech stack.
SocketCluster is an open source tool with 6.1K GitHub stars and 312 GitHub forks. Here’s a link to SocketCluster's open source repository on GitHub
