Can a function access the values in the settings.js file?

[Paul Woodard]

Is it possible for a function node to access the things set in settings.js? For example I want to get the name of the flow file. I know it defaults to flows_<hostname>.json but it could have been set to something different in settings.js.

No, it only has access to things under functionGlobalContext property within the settings file.

That's not entirely true... Heh heh heh.

Use "Inject", "exec", and "debug"

[{"id":"780bd2d4.017dd4","type":"inject","z":"20240cab.96b054","name":"","topic":"","payload":"","payloadType":"none","repeat":"","crontab":"","once":false,"x":81,"y":80,"wires":[["a398cebc.83fd4"]]},{"id":"a398cebc.83fd4","type":"exec","z":"20240cab.96b054","command":"cat ~/.node-red/settings.js","addpay":true,"append":"","useSpawn":"","name":"","x":273,"y":81,"wires":[["40de8c1c.e0ac5c"],[],[]]},{"id":"40de8c1c.e0ac5c","type":"debug","z":"20240cab.96b054","name":"","active":true,"console":"false","complete":"false","x":518,"y":67,"wires":[]}]

Now, all you need do is write a parser. :-D



Also, if your Node-Red user can SUDO, you can also apt administration via a flow. For example...

$echo <password> | sudo -S <command>

and with this you can run whatever as root. Preferrably, you can do apt-get install {{payload}}

$echo <password> | sudo -S apt-get install {{payload}}

for easy package additions.
