Workflow Node Schema — Inputs, Outputs & Connection System

Node Anatomy

Every workflow node is a JavaScript module with this structure:

export default {
  id: "unique-id",        // Unique identifier
  name: "Display Name",   // Shown in UI
  icon: "mdi-icon-name",  // Material Design Icon
  category: "Basic",      // Grouping in palette
  inputs: [...],          // Input ports
  outputs: [...],         // Output ports
  fields: [...],          // User-configurable parameters
  async execute(inputs, fields, context) {
    // Node logic here
    return { outputName: value };
  }
};

Port Types

• trigger — Execution flow (connects to trigger ports)
• data — Value passing (any JSON-serializable data)
• error — Error output for catch handling

Connection Rules

• Trigger → Trigger: Controls execution order
• Data → Data: Passes values between nodes
• One output can connect to multiple inputs
• Connections form a DAG — no cycles allowed
