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.

Running Node-RED on the cloud

This time, we will use IBM Cloud. The reason for this is that IBM Cloud has Node-RED Starter Kit on it. This is a kind of software boilerplate that includes services needed for Node-RED on the cloud, such as a database, CI/CD tools, and more.

If you have not used IBM Cloud yet, don't worry – IBM provides a free IBM Cloud account (Lite account) with no credit card registration needed. You can register for an IBM Cloud Lite account at

Before using Node-RED on IBM Cloud, you need to finish the registration process for your IBM Cloud Lite account.

Important Note

In this book, we strongly recommend that you select a Lite account when using IBM Cloud. You can upgrade from a Lite account to a standard account (PAYG/Pay as you go) at your own will. This means you can automatically upgrade to PAYG by registering your credit card.

Please note that services that can be used free of charge with a Lite account...
