Any good resources for how to create as custom Node?

scrounging the internet and finding very little to none

@ChrisFlick As far as I know there isn't really anything comprehensive.

Luckily there is an example file in the custom nodes folder. The comments within the example code are very helpful. If you have Python knowledge, between that and the many examples out there in the wild, you should be good to go. Once you get a basic node working, you can also use javascript to enhance it.

Things you need for a basic working node.

• A .py file with:
  • A node defined by a properly formatted class
  • NODE_CLASS_MAPPINGS: A dictionary that maps the name for the node (a string that should not overlap existing nodes) and the class
  • Optionally NODE_DISPLAY_NAME_MAPPINGS will allow a more human readable name to show up in the context menu if it is also provided.
• An init.py file. This tells ComfyUI where the previously mentioned mapping dictionaries are located. It can be very simple with very few lines. Look at other custom nodes to get the basic idea.

Optional:

• A requirements.txt file if there are any additional dependencies that your node will need.

That's basically it. 2 to 3 files in a folder will give you a good start. Then you can start experimenting with adding complexity.

its this I am having trouble with understanding. I am understanding the basic principle of making custom nodes but it would be really helpful to have any resources on how to integrate javascript into it...
I would love to make a simple node just changing the document title to a given String.

Any simple examples of how to render custom html inside a node? Can one put a reactjs component inside comfyui node?

I have something in mind to improve on one of the existing nodes usability wise

I don't know if this will be helpful to you.
