Chapter 4: Learning the Major Nodes
In this chapter, you will learn about the major nodes used in Node-RED. Node-RED, which is an open source project, provides some major nodes by default, but it is possible to import and use nodes from the public library as required.
Node-RED has a lot of nodes. Therefore, this book is not sufficient to explain all of them. So, in this chapter, let's pick up the main nodes and most commonly used basic nodes and learn how to use them, exploring these topics in this chapter:

- How to use nodes
- Getting various nodes from the library
By the end of this chapter, you will have mastered how to use major nodes in the Node-RED flow editor.
