Hi ,

New to Node Red. Is there a classification of nodes that I can see like IOT nodes or SQL nodes etc., ? If so how do I access ?

All your responses appreciated.

Nodes are free to tag themselves however they want with the keywords they provide in their package.json file. We use those keywords as part of the search index on [https://flows.nodered.org/](https://flows.nodered.org/). So if you search for `sql`, you'll get any node that mentions sql in either its name, description or keywords.
