Description

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.

What you will learn

Understand the history of Node-RED and why you need to learn a flow-based programming tool

I like this book as a beginner guide. Practical examples, step-by-step explanations. All I was searching for: both for local computation and cloud one, API call from other applications, HW control, AI usage. There are some typos, as usual for Packt publisher, but on the other hand practical easy to read instructions.

The world of the Internet of Things (IoT) is extremely active right now and there is a lot of interest in this domain. For those with a desire to learn more about IoT but without embedded development experience, unfortunately, the world of connected edge devices may seem like a mysterious and forbidding place. There is definitely a need for introductory material, so this is a welcome offering. Node-RED provides a low-code/no-code context that lets you accomplish quite a bit without much prior knowledge. Whether you're a novice or a veteran programmer, I think you'll find the book, "Practical Node Programming" to be a pleasant and informative read. The author, Taiji Hagino, is a seasoned developer with several years as a developer/advocate in the Node-RED community, and you'll benefit from his perspectives.The book contains a nice introduction to the history of Node-RED and Flow-Based Programming (FBP). Impatient readers might skim through this section, but there are some interesting tidbits--including a mention of the Node-RED library which contains an impressive collection of open-source libraries you might find useful in building your own projects. Immediately thereafter you are setting up your local development environment, getting hands-on experience with FBP using the Node-RED Flow Editor, and using nodes from the Node-RED library. You'll find a mixture of standalone and cloud-based solutions presented here, and I thought that was a good approach.The book picks up the pace as you walk through implementing Node-RED locally, on edge devices, and in the IBM cloud. Example projects include calling web APIs, using Git, database persistence (with CouchDB), sensors (temperature & humidity), and even a Watson chatbot! These projects provide a good overview of the various types of IoT scenarios you're likely to be interested in (including a solid exposition on MQTT and pub/sub architectures). Also timely is a brief tutorial on cloud-based data aggregation and visualization.The book is highly visual, containing many instructive screenshots of the IBM Cloud tool as well as the Flow Editor. While beneficial, one of the potential downsides is that as IDEs inevitably change, there's a risk that these visuals could go out of date. For example, being new to the IBM Cloud, I confess to having stumbled a bit where I thought the screenshots didn't match what I was seeing. (On a side note--I should also mention that I thought the IBM Cloud UI was very well put together, and it's possible that IBM's Cloud offering deserves more respect than it seems to have gotten in the industry). Fortunately, there's an active Node-RED community, and resources are provided in the Appendix for different online resources.Overall, I think it's a solid effort for an timely topic. The subject area is broad but the Taiji manages to strike a good balance between depth and breadth here. The people who will benefit the most from this volume are those with some development experience (though not necessarily embedded development), but there is something here for everyone.

As an IT professional but with no experience of Node-RED or Raspberry Pi, I found this book easy to read with every step along the way illustrated with screenshots. It also introduced me to related technologies that I now intend to follow up. Although some of the examples can be found on the Internet, I would probably not have known to go looking for them without this book. I shall be referring back to this book for many useful links and tasks.
