SendKey Function

[callofbeauty28]

Hi, I simply want to know how to send a key input (like F1) from a plugin using onKeyDown().

Elgato’s official Hotkey action can simulate native key presses, so I’d like to do the same thing within a plugin.

The goal is to display data received from an external application and send input (e.g. holding down the F1 key) back to that application in response.

Hi @callofbeauty28,

In order to send keyboard inputs from a Node.js Stream Deck plugin, you will need to utilize a library that includes a native addon for communication to the users system. We are actively developing a System library for the Stream Deck SDK that will allow for easy keyboard simulation, but we do not have a release date at this time.

Sadly, the most popular open-source option (nut-js) was just taken down, but you may find some luck with robotjs although that too has not seen an update in several years. Just be aware that when using native addons you will have to copy the .node file(s) from within the node_modules/<package> folder into the .sdPlugin folder in order for them to work after bundling.

Hope this helps!
