packaging nodes and discovery

[Julian Lyndon-Smith]

I was looking at the packaging guidelines, and was curious ;)

http://nodered.org/docs/creating-nodes/packaging.html

Specifically, "It is suggested they use node-red-contrib- as a prefix, although that is not a requirement."

Does this mean that there may be some node-red nodes that do not follow this convention ?

I was curious because I was wondering about the discovery process - do you loop through all the folders in node_modules to find the nodes ? If there is no module naming requirement, I would have to assume that you then have to load each package.json up to see if there are the node-red keys inside. This would seem to be a slow process.

Is the discovery process as I've described, or am I just being daft ? ;)

Hi,

the discovery process loads all of the package.json files it finds looking for the node-red keys - it does not care what the name of the package is. The reason for the naming convention is to make it clear that a package isn't one maintained by us, so we don't get deluged with support requests.

I did some work to see where the time was being spent on start-up, to try to make it faster. On a raspberry pi, it took 14 seconds to start up - including the time to discover what nodes were installed. I changed the code to give it a hardcoded list of nodes, so it didn't have to scan - it then took 13.8 seconds to start. So the discovery process was only taking 200ms - the bulk of the time was loading the nodes themselves after they had been discovered.

Thanks for the info - I since discovered the "recommended" approach of npm installing the nodes in a separate folder and pointing node-red to that folder. That makes a little more sense, as I have a boat-load of non-node-red nodes in my node_modules ;)
