If you are having trouble with this please contact your System Administrator. Please note if the module does not install and throws up error messages regarding permissions, you will need to run CMD in Administrator mode. Now we can begin to install Node-RED, navigate to CMD and input the command: npm install -g -unsafe-perm node-red NPM should be installed by default when installing Node.js. NPM is a package manager for the JavaScript programming language, this is needed for installing additional Node-RED packages which we will need later. The output should look something like this: This command checks if both Node.js and NPM are correctly installed, and if so it will return a version number. Once the installation is complete, open up a Windows command prompt, you can open a command prompt by using the keyboard shortcut (Windows key + r) type cmd and then once the command prompt has opened, input the following: node -version & npm -version When installing Node.js for use with Node-RED it is recommended that you install the 10.XX.X. Node.js can be downloaded from the official Node.js website. Node.js is a JavaScript based programming language and must be installed before Node-RED. Node-RED uses a runtime engine called Node.js. All required download links can be found on the official Node-RED and NodeJS websites.

The following are instructions on how to install Node-RED on a Windows based operating system.

A Brainboxes Remote Ethernet I/O device.

An online flow library allows you to share your best flows with the world.

The flows created in Node-RED are stored using JSON which can be easily imported and exported for sharing with others.

A built-in library allows you to save useful functions, templates or flows for re-use.

JavaScript functions can be created within the rich text editor.Modbus TCP client to talk to Brainboxes Remote IO devices.REST clients to query data on other servers.Some examples of the many functions available are: The software provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its run-time in a single-click.Īlthough the concept of flows, nodes & palettes may sound unfamiliar, Node-RED makes programming simple by using a visual representation of code in blocks with lines between them. Node-RED is a visual programming tool aimed at connecting hardware devices, APIs and online services in alternative ways, without the need for traditional programming experience.
