Developing custom nodes from webui extensions

You can implement ComfyUI custom nodes into other webui extension. sd-webui-comfyui will scan the webui extensions directory and inject the nodes of enabled extensions into comfyui upon startup.

Here is the directory structure expected by the custom node scanner:

sd-webui-your-extension
├─ comfyui_custom_nodes
│  ├─ node1.py
│  ├─ node2.py
│  ...
├─ comfyui_custom_scripts
│  ├─ extensions
│  │  ├─ node2.js
│  │  ...
│  ├─ additional_scriptA.js
│  ├─ additional_scriptB.js
│  ...
├─ scripts
...

• comfyui_custom_nodes/ contains python modules custom nodes. Here is an example from the comfyui repo
• comfyui_custom_scripts/ contains any additional javascript code you want comfyui to statically serve
• comfyui_custom_scripts/extensions contains ui code for custom nodes. Here is an example from the comfyui repo

On the side of the web browser, if your extension directory is named "sd-webui-your-extension", then any file under comfyui_custom_scripts/ will appear at the path http://localhost:8188/webui_scripts/sd-webui-your-extension/
