This project started as a fork of ReteJS (https://github.com/retejs/rete)

• Sockets are the attachment points for Connections, and handle Connection compatability

• Connections manage relationships between Inputs/Outputs

• IO contains Connections, as well as a reference to the Node and Socket

• Inputs/Outputs extend IO

• Inputs

• Outputs

• Nodes

• Controls manipulate data on Nodes or Inputs

The engine is simply an event emitter at its core
