Demo: Conditional Set Execution via IF on Function Output

This workflow serves as a companion example for n8n's IF node documentation, showcasing how to implement conditional branching based on data from a preceding Function node. It begins with a Manual Trigger, followed by a Function node that generates two items with distinct 'id' values (0 and 1). The IF node evaluates each item's 'id'—routing to a 'Set' node (setting 'name' to 'n8n') if true (e.g., id equals 0), or to 'Set1' (setting 'name' to 'nodemation') if false.

The primary benefit is educational: it simplifies understanding multi-item handling and dynamic routing in n8n, preventing common pitfalls like incorrect expressions in conditions. Users gain hands-on insight into expression syntax (e.g., {{$node["Function"].json["id"]}}) and connection mapping for true/false outputs.

Use cases include prototyping conditional automations, such as processing API responses differently based on status codes, user roles, or data thresholds. It's perfect for developers building scalable workflows in IT tools, IoT device management, or any scenario requiring decision-based node execution, saving time on trial-and-error debugging.

Extend it by integrating real data sources (e.g., HTTP Request) or actions (e.g., email notifications), transforming this demo into production-ready logic for device control or data processing pipelines.
