What is a node-red registry?

I am quite new to the development background.
I do not understand what a 'node-red registry' is and how to use it while you are creating your own nodes.

can someone give me a valuable source of information or examples to understand the topic.

TIA

Hi @elvisj007

The node-red registry is an internal component of Node-RED that is responsible for discovering and loaded nodes into the runtime. The details of it are not something a node author really needs to care about.

The main source of information on how to create nodes is the documentation: Creating Nodes : Node-RED
