The following is a quick guide on getting basic status LED functionality working with TrueNAS running on the UGREEN DXP4800 Plus. Theoretically, it should work on all models (with some small revisions to the script), but I only have a DXP4800 Plus. :)
This guide is for cron job that runs a script to update the LEDs every couple minutes, but I'm sure the following can be modified for blinky LEDs as well.

They say that one of the pros of NodeJS is that you use the same language on the back-end and the front-end, so it's easy to share code between them. This sounds great in theory, but in practice the synchronous dependency handling in NodeJS works completely different than any client-side frameworks (which are asynchronous).
Usually that means that you end up copy-pasting your code between your NodeJS sources and your client-side sources, or you use some tool like Browserify, which is brilliant, but they add an extra step in the build process and most likely will conflict with the dependency handling of the framework of your choice (like AnularJS DI). I couldn't look in the mirror if I would call that code sharing.
Fortunately, with a couple of lines of boilerplate code, you can write a module which works in NodeJS and AngularJS as well without any modification.
No globals in the front-end, and dependencies will work. The isNode and isAngular va
