Node-RED is a new open-source tool created by the IBM Emerging Technology team that lets you build applications by simply wiring pieces together. These pieces can be hardware devices, web APIs, or online services.
On IBM Cloud it’s easy to create a new Node-RED runtime. With just a few clicks you have a working environment, ready for you to create your new application. In this article, we’ll show you how to build—in just a few minutes—a real-time chat application on Node-RED using IBM Cloud.

Build your next app quickly and easily with IBM Cloud Lite. Your free account never expires, and you get 256 MB of Cloud Foundry runtime memory, plus 2 GB with Kubernetes Clusters. Get all the details and find out how to get started. And if you’re new to IBM Cloud, check out the IBM Cloud Essentials course on IBM Developer.
Every Node-RED application can be imported and exported using the JSON format. So let’s import our chat app into the new sheet.
We will explain what each piece does later on in this article, but now it’s time to deploy and run your application.
In this section, we explain the code behind our application in more detail. You can skip this section, but we recommend you read through it to better understand how the app is built and to learn more about how Node-RED works.
Node-RED simplifies code development by providing us with a set of nodes ready to be wired together and used. As shown in this article, it takes very little work to have a server set up on IBM Cloud to use in your projects. You can enhance this simple chat application even more by adding new nodes and creating new flows to connect to the existing ones.
