Node-Red 101 Series From Scratch

Node red 1O1 series from scratch is a course designed for beginners who have less or zero experience with Node-Red.



What is Node-Red?

Node-RED is a programming tool for wiring together hardware devices, APIs, and online services in new and interesting ways.

Node-RED provides a browser-based flow editor that makes it easy to wire together flows using the wide range of nodes in the palette. Flows can be then deployed to the run time in a single click.

JavaScript functions can be created within the editor using a rich text editor. A built-in library allows you to save useful functions, templates or flows for re-use.



Node-Red History

Node-RED is a flow-based programming tool, originally developed by IBM’s Emerging Technology Services team and now a part of the JS Foundation.

Flow-based programming Invented by J. Paul Morrison in the 1970s, flow-based programming is a way of describing an application’s behavior as a network of black-boxes, or “nodes” as they are called in Node-RED. Each node has a well-defined purpose; it is given some data, it does something with that data and then it passes that data on. The network is responsible for the flow of data between the nodes.

It is a model that lends itself very well to a visual representation and makes it more accessible to a wider range of users. If someone can break down a problem into discrete steps they can look at a flow and get a sense of what it is doing; without having to understand the individual lines of code within each node.

Node-RED started life in early 2013 as a side-project by Nick O’Leary and Dave Conway-Jones of IBM’s Emerging Technology Services group.

What began as a proof-of-concept for visualizing and manipulating mappings between MQTT topics, quickly became a much more general tool that could be easily extended in any direction.

It was open-sourced in September 2013 and has been developed in the open ever since, culminating in it being one of the founding projects of the JS Foundation in October 2016.
