Node-RED – Part 3: Setup Node-RED on local machine


Welcome to part 3 of my Up and Running with Node-RED video series. In Part 2 I showed you how to setup a Node-RED runtime on IBM Cloud (aka IBM Bluemix).

In this video tutorial, I take you through a step by step process on how to setup a Node-RED runtime on your local machine.

Why Node-RED on local?

The power of Node-RED is that it not only runs as a lightweight Node.js module, but that it has nodes which provide various services that span across cloud platforms, hardware devices and operating systems.

Running Node-RED on local provides you with options that might not be available when running it in the cloud. A quick example of this is JDBC connectivity. This is not easily achieved when Node-RED runs inside a container in the cloud, because Java would need to be running inside the same container. On local, however, Java can be installed, which means you can now connect to relational databases via Node-RED.

Another example is how Node-RED can interact with your operating system’s files and folders…monitoring changes and triggering flows when changes occur.

In the end, depending on your requirements, you could easily run Node-RED both in the cloud and on local. The opportunities are endless, which you will soon discover in my next set of Node-RED video tutorials.

It’s Video Time

This video gives you everything you need to get Node-RED running locally, however, everyone’s environment is different. Just in case, here is a link to the Node-RED docs, should you be forced to start troubleshooting.
