Node-RED is a programming tool that is developed to connect different devices, APIs, and online services. It allows developers to create, design and program the connections between different systems with great ease. In this tutorial, you will learn how to install Node-RED on OpenSUSE Latest using the terminal.
Before we begin with the installation of Node-RED, please ensure that you have the following prerequisites:
Before you start the installation process, it’s a good idea to ensure that you have the latest packages and security updates installed.
To update the system, run the following command:
sudo zypper update
This command will update your OpenSUSE system with the latest packages and security updates.
The next step is to install the required dependencies that the Node-RED package needs to run. Use the command below to install these dependencies:
sudo zypper install make gcc gcc-c++ nodejs8-devel
This command will download and install the required dependencies for working with Node-RED. It may take some time depending on your internet speed.
The next step is to install the Node-RED package itself. We’re going to install Node-RED using the npm package manager. Run the following command to install Node-RED:
sudo npm install -g --unsafe-perm node-red
This command will download and install Node-RED on your OpenSUSE machine. It may take some time depending on your internet speed.
After installing Node-RED, you can start the service by running the following command in the terminal:
node-red
This command will start the Node-RED service and display output similar to this:
