This is a Launchd script for Node-Red so that it launches on stratup and restarts if it crashes.
This script assumes you have installed Node-Red using the command sudo npm install -g node-red
Make sure to change /Users/YOURUSER to your own user's home directory path.

You will need to place this script in /Users/YOURUSER/LaunchAgents and then run launchctl load -w org.nodered.plist from that directory.

To stop the daemon you can run launchctl unload org.nodered.plist

Here's an alias you can add to your .bashrc or .bash_profile file to quickly restart node-red:

alias restartnode="launchctl unload ~/Library/LaunchAgents/org.node-red.plist ; launchctl load -w ~/Library/LaunchAgents/org.node-red.plist"

Nice work. There is an inconsistency in the naming of your plist file. Either name the plist file org.node-red.plist or org.nodered.plist. The alias you provide will not work otherwise. Newcomers will likely not figure this out.

Thanks for helping out the "other" platform.

Thanks, @natcl. Very useful. Saved me time.

The first comment says the script should go into "/Users/YOURUSER/LaunchAgents" but it appears it should really go into "/Users/YOURUSER/Library/LaunchAgents" instead?

Thanks, @NatCi.
One question: When launchctl launches node-red I get the following error in the node-red.log file:
4 Feb 22:29:36 - [info] Palette editor disabled : npm command not found

When I run node-red from the command line I don't. Do I need to specify anything else in the .plist file? I installed nom using homebrew.

I figured it out minutes after posting my comment :-)
I needed to add the following to my .plist file:

    <key>EnvironmentVariables</key>
    <dict>
        <key>PATH</key>
        <string>$PATH:/usr/local/bin</string>
    </dict>

Hope this helps others

Thanks @WizBangCrash,

but where (in file) did you set your instruction?
I set this in org.nodered.plist this:
<key>PATH</key> <string>$PATH:/usr/local/bin</string>

But Pallete still not working...

Here is the correct .plist script with palette working:
