Node-RED, the visual low-code programming tool for event-driven applications, has released version 2.0, which is lighter than its predecessor. Node-RED is built on Node.js and was developed to help combine hardware devices like Arduino, Raspberry Pi, and other APIs into apps for IoT (Internet of Things).

The first time the tool became available was eight years ago and was one of the founding projects of the JS Foundation (now the OpenJS Foundation).

The second major release saw the team behind Node-RED decide to drop Node.js versions that aren’t supported anymore to make internal dependency updates.

Why the late release?

Figuring out how to make this happen took a while, which is why this release did not land in April as it usually does. Now that this task has been dispatched, the team can concentrate on adding and refining features, including new tools included in the release.

Users will need Node.js 12.17 or later installed to use Version 2 of Node-RED, which has new features like the node-red admin init command.

The tool will ask a couple of questions regarding project workflows, security, node, and editor settings when users run it for the first time.

A return to a regular rhythm

The opening questions can be turned into a comprehensive settings file, which is especially helpful to those using Node-RED for the first time.

Those familiar with the settings should still check out the new default since the team rearranged the settings to make them clearer. V2 also comes with the standard flow file name hardcoded to prevent issues arising from switching networks.

That is not to mention all the other changes highlighted on the official website. This release will see the team get back to the usual quarterly releases, and version 2.1 should be ready by October.
