The document introduces Node-RED, a flow-based development tool for connecting hardware devices, APIs, and online services. It covers its functionality, including various nodes for data manipulation and integration with platforms like Salesforce and IoT devices. Additionally, it discusses deploying Node-RED on Heroku, highlighting advantages and caveats while encouraging exploration and participation from users.

7. Meet some of the Nodes (1/3)
Debug Node
● Output option
○ Log
○ Debug Window
● Output scope
○ msg
○ payload
○ custom
Inject Node
● Insert various messages
○ time stamp
○ object
○ String
● Trigger options
○ on startup
○ on schedule
○ on click
Just the basics

8. Meet some of the Nodes (2/3)
HTTP Response Node
● Partner to Endpoint Node
● Set Header Values
● Set Status Code
● Set cookies from msg.cookies
HTTP Endpoint Node

○ parameters
○ headers
○ cookies
○ body
Basic HTTP

9. Meet some of the Nodes (3/3)

10. NodeRED
Gui driven flows

11. Demo
… and 2000 of their friends

12. Runs everywhere with everything
Almost
• Windows
• Linux
• Mac
• Heroku
• AWS
• GCE
• Azure
• Raspberry Pi
• QNap
• Synology
• Mainframe
2034 Nodes*
1281 example flows
* as of 1 June 2019

13. Use cases
Limited only by your imagination
• Mock API Endpoints
• Connect to Salesforce
• Save to database
• Transform and forward
• Connect (both ways) to IoT
• Prototype custom actions
• Quick Dashboards

14. NodeRED on Heroku
Caveats and Advantages
Advantaged
• https works out of the box
• custom domain available
• multiple instances
• Rich selection for databases etc
Caveats
• No hardware access
• Runtime is epidermal -> save your flows.js file local/github
node-red --settings ./.node-red/settings.js --userDir ./.node-red

15. There is much more
Topics not covered:
• Roll you own Nodes
• Headless operation
• GitHub integration
Online resources:
● NodeRED.org

Got another hour or two or three ...

16. Is that the YETI?
