#Overview

Nodes are the basic units of logical orchestration in workflows. A workflow can have any number of nodes configured. Each node's type represents an instruction that determines the node's behavior. The node's configuration corresponds to the instruction's parameters, which determine the data objects or other content for its behavior operations.

From a functional perspective, currently implemented nodes can be divided into four major categories (a total of 24 types of nodes):

• Process Control
  • Condition
  • [Delay] (provided by plugin @tachybase/plugin-workflow-deley)
  • End Process
