🧠 n8n-nodes-function

Blueprint-style function system for n8n, inspired by Unreal Engine 5.

Define reusable logic blocks with Function, call them with CallFunction, and return values with ReturnFromFunction.

📦 Features

• 🧱 Define reusable logic with named Function nodes
• 📞 Call functions with dynamic parameters using CallFunction
• 🔁 Return values cleanly using ReturnFromFunction
• 🧬 Nested function calls - functions can call other functions with isolated return values
• 🌍 Global functions - share logic across workflows

ℹ️ Gotchas

• 🟢 Functions only work on Active workflows.
• 🔃 To detect changes to new/existing Function nodes, toggle the workflow off/on.

  The Call Function and Return from Function do not require toggle workflow after changes.
  But function names/params from Function nodes require toggling the active state.
  It's not an intentional choice, it's just a limitation of how trigger nodes work in n8n.
