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.

Summary

In this chapter, you learned how to create a server-side sample flow (application) by following a real IoT use case. These were simple tutorials, but I am sure it will be beneficial for you so that you understand how to make flows for IoT server-side applications.

The flow steps we created here will help you create different flows for other server-side applications in the future.

In the next chapter, we will use the same IoT use case we used in this chapter, but we will create a practical sample flow (application) that will call a web API.
