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.

Installing Node-RED for Windows

In this section, we will explain how to set up Node-RED in a Windows environment. This procedure is for Windows 10, but it will work for Windows 7 and Windows Server 2008 R2 and above as well. Windows 7 or earlier versions of Windows Server 2008 R2 are not currently supported and are not recommended.

For Windows, installing Node-RED as a global module adds the node-red command to your system path. Run the following command in Command Prompt:

$ npm install -g --unsafe-perm node-red

Once you have finished installing Node-RED, you can use Node-RED straight away. Please run the following command. After running this command, you will recognize the URL being used to access the Node-RED flow editor. Usually, localhost ( with the default port 1880 will be allocated:

$ node-red
Welcome to Node-RED
