I used to use node red on truenas 12.3. now I am forced to use truenas 13.0 and found that Node RED is not available. Since I have no other way to host node red, I wanted to find out whether I can still install it on truenas 13. Or whether it can be added again to the community plugin list.
Welcome to the forums @EliasZoockt
I can't fully answer the question - I know nothing about TrueNAS - someone here might though.
Or whether it can be added again to the community plugin list.
I would expect the TrueNAS community forums to have more insight, given it may have been a member of said community who created the previous plugin?
Node RED its self will need Node JS >= 14.x (but 16.x is recommended)
Node RED can be installed either with NPM or via an install script, See : GitHub - node-red/linux-installers: Node-RED install scripts for various flavours of Linux
I wouldn't know if this script can run in TrueNAS
Side Note: I have moved this to General - as its not about using the forums.
I run 2 instances of Node-RED (version 3.0.2) in a TrueNAS Core (version 13-U4) Jail. However it has not been installed in version 13, but it has been installed in version 12, or even version 11.
I use it already for a long time. After updating from 12 to 13 (or even from 11 to 12) it remains functional.
I noticed it disappeared from the list: Apps - TrueNAS - Welcome to the Open Storage Era
I saw you raised a similar question in This plugin needs an update · Issue #10 · tprelog/iocage-node-red · GitHub
As you have probably read there, the use of plugins is discouraged. They recommend to use a clean jail and to install it the regular way.
To install NodeJS and npm you can follow the guideline at: https://computingforgeeks.com/how-to-install-node-js-lts-npm-on-freebsd/

Wait for their answers.
