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.

Chapter 11: Visualize Data by Creating a Server-Side Application in the IBM Cloud

In this chapter, we will create a server application to visualize data that has been sent from an edge device in the IoT, using Node-RED. For a server-side application, I would like to use the IBM Cloud here. By following the tutorials in this chapter, you will master how to visualize sensor data on a server application.

Let's get started with the following topics:

  • Preparing a public MQTT broker service
  • Publishing the data from Node-RED on an edge device
  • Subscribing and visualizing data on the cloud-side Node-RED

By the end of this chapter, you will have mastered how to visualize sensor data on cloud platforms.
