Overview of this book

Node-RED is a free and open source flow-based programming tool used to handle IoT data that allows programmers of any level to interconnect physical I/O, cloud-based systems, databases, and APIs to build web applications without code. Practical Node-RED Programming is a comprehensive introduction for anyone looking to get up to speed with the Node-RED ecosystem in no time. Complete with hands-on tutorials, projects, and self-assessment questions, this easy-to-follow guide will help you to become well versed in the foundations of Node-RED. You’ll learn how to use Node-RED to handle IoT data and build web applications without having to write complex code. Once you’ve covered the basics, you’ll explore various visual programming techniques and find out how to make sample flows as you cover web development, IoT development, and cloud service connections, and finally build useful real-world applications. By the end of this book, you’ll have learned how to use Node-RED to develop a real-world application from scratch, which can then be implemented in your business.

Publishing your own node as a module in the Node-RED Library

Here, we will publish the created node in the Node-RED library. To do that, some work is required. So far, you have created your own node and confirmed that it can be used only in your environment. However, since it is a unique node created by you, let's publish it on the internet and have everyone in the world use it. To do this, you need to publish your own node to a location called the Node-RED library, which can be found here: https://flows.nodered.org/.

Important note

The Node-RED library is a community-based place to publish nodes and flows. Therefore, you should avoid exposing incomplete or useless nodes. This is because the Node-RED users should be able to find the nodes that they want, and it is not desirable to have a mix of unwanted nodes.

So, although this chapter will explain how to publish nodes, please avoid exposing test nodes or sample node-level ones.
