Node-RED is a flow-based programming tool for wiring together hardware devices, APIs and online services that was created by IBM in 2013 and is now a founding project of the JS Foundation. It uses a browser-based flow editor to help develop IoT applications and can be used both at the edge on devices like Raspberry Pi as well as in the cloud. Node-RED features a wide range of nodes that allow it to interface with services, protocols, and devices.

1. Prototyping the Internet of
Things with Node-RED

2. Node–RED
Flow- based programming
for the Internet of Things
• Browser – based editor
• Node.js runtime
• Extendable palette

3. 2013: Created by IBM Emerging
Technology Services and open
sourced later that year
2015: Added to the default
Raspberry Pi image
2016: Became a founding project of
the JS Foundation.
2018: Hit 1,000,000 installs

4. Flow Based Programming
• Invented by J. Paul Morrison at IBM in early 1970’s
• A network of asynchronous processes communicating by means of
streams of structured data chunks
• Each process is a black box – it doesn’t know what has come before it
or what comes after it ; it just acts on the data it receives and passes
the result on

5. Why Node – RED ?

9. What is a Node-RED Node ?

12. From the Edge to the Cloud
Easily installed on the default Raspberry Pi image,
Node-RED can be used out of the box to begin
creating IoT applications
Available in the IBM Cloud catalog as a quick start application,
it takes moments to create cloud applications that combine
services across the platform.
Easily installed on other cloud platforms.

16. Other Input Nodes
HTTP – Act as an HTTP endpoint; great for building
RESTful services
IBMIoT – Receive messages from an attached Watson
IoT Platform
Also can receive from Websockets, MQTT (pick your own
broker), TCP and MQ Light

17. Other Output Nodes
HTTP Response; required as the final node
when the input comes from an HTTP
Request
IBMIoT – send events out to the attached
Watson IoT account
Twilio – send SMS messages via the Twilio
service
IBM Push – Send Push notifications to
mobile devices
Also can send requests through TCP, UDP,
MQLight, WebSockets.
