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 functions.
Security
By default node-red installs completely open and you can access the admin interface and create and deploy flows without having to login.
However you can secure node red by requiring username/password authentication, and also SSL.
