Node-RED Programming
Learn the core programming concepts you'll use every day in Node-RED. This section covers the fundamental building blocks that will help you create more sophisticated and reliable flows.
What's Covered
Programming in Node-RED means working with flows, nodes, and messages. Even though you're working visually, you'll still need to understand key programming concepts like conditional logic, loops, and data manipulation. This section teaches you how to implement these concepts using Node-RED's visual approach.
- How to Debug Node-RED Flows Using Debugger: Debug Node-RED flows using the Debugger. Learn to set breakpoints, step through execution, and inspect messages for efficient troubleshooting.
- How to Use If-Else Logic in Node-RED: Learn how to implement If-Else logic in Node-RED with our step-by-step guide. Use Function and Switch nodes for dynamic, conditional flows.
- How to implement loops in Node-RED flows: Learn how to implement while, for, and for...of loops in Node-RED with core and custom nodes for efficient data processing and automation.
- How to Filter, Map, Sort, and Reduce Data in Node-RED: Learn how to perform data transformation in Node-RED with a low-code approach.
