Introduction to Node Red
What is Node Red? –Node red is a flow based tool and IOT Dashboard developed by IBM and written in Node.js.It is an Open Source project
Node red lets you easily create program flows by joining together black box functions (nodes) using a web interface.
Introduction Video
A quick overview of node-red and an introduction to flows.
Node-Red Basic Course
To get you started I’ve created a basic course designed for complete beginners. The course introduces users to the node-red admin interface and basic flows and consists of a collection of tutorials and videos.
- How to Install and Start Node-Red
- How to use the Admin Interface, nodes and flow basics.
- Securing Node-Red with SSL and Username Authentication
- Understanding the Message object
- Storing Data in Node-Red Variables
- How to Create a Basic Node-Red Dashboard
The Node-Red Command Console
This is the command console used to start node-red.
It displays useful information such as the admin port, current flow directory, and also output from the node.log function used in node function nodes.
Security
By default node-red installs completely open and you can access the admin interface,create and deploy flows without having to login.
However you can secure node red by requiring username/password authentication, and also SSL.
