Hello
I have imported a module in nodered, see screenshot below. I no longer use this module, how do I completely delete it from Nodered?
If you remove that entry and re-deploy, does it not remove the module?
If not, access a server terminal then:
cd ~/.node-red
npm remove node-rainbird
After running the npm remove command, restart node-red.

Thanks - I am just trying to understand a bit more about this.
I downloaded this into my pallete node-red-contrib-rainbird (node) - Node-RED
On that link it states that "This package uses a modified version of [node-rainbird] (GitHub - bbreukelen/node-rainbird: Rainbird controller in Node.js)". This is the class that I was using originally but I do not use it in my flow anymore, since I've now downloaded that node.
In the npm list I can see both the original node-rainbird (original post) and the new node node-red-contrib-rainbird.
Also in package.json I can still see "node-rainbird" as a dependency along with the new node I downloaded ("node-red-contrib-rainbird").
Will downloading the new node automatically install node-rainbird since it states that it is based on it? Or am I safe to remove node-rainbird using npm remove node-rainbird. I don't want to break the new node I've downloaded since I've spent 4 hours creating flows with it.
node-rainbird is a node.js package, not specific to node-red. And somewhat confusingly, not a "node" in a node-red sense.
The contrib package, if it relies on a node.js package, will self-install that package for you as a dependency and npm will remove it for you when you remove the contrib package - as long as it isn't being used by another package.
If you ever get into a complete mess with node-red packages, use a command prompt, go to the ~/.node-red (AKA "userDir") folder, stop node-red and delete (or rename if you are paranoid 
) the node_modules folder. Then check that the dependencies section of the package.json file only has node-red packages that you actually want. Then do npm install. When that finishes, you can restart node-red and you should be good to go.
Note that, if you do follow that "nuke-from-orbit" approach, you might have to start node-red in safe mode to be able to remove any nodes that you got rid of but forgot to remove from your flows before-hand. Of course, if you renamed the node_modules folder, you can restore it, change your flows and then do the other part again.
Node-RED really is quite robust. 
If you have a problem then all you have to do is restore your flows file from the backup that you will update before doing any more.
Thanks all!
