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.

Why you should use Node-RED for web applications

So far, this book has explained that Node-RED is an easy-to-use tool for the Internet of Things (IoT). There are many cases where Node-RED is used as a solution in the IoT field.

However, recently, Node-RED has been recognized as a tool for creating web applications as well as IoT.

I think one of the reasons is that the ideas of no-code and low-code have become widespread in the world. Nowadays, the number of people who know flow-based programming tools and visual programming tools is increasing, and they are being used in various fields.

It would be natural for Node-RED, which is made with Node.js, to be used for web applications.

The project function that we learned in the previous chapter, in collaboration with Git/GitHub, may also be a part of the flow of web application development culture.

In this chapter, we will create a ToDo application that is very suitable as a piece of development for tutorials.
