Developing custom nodes from webui extensions

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

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 custom nodes. This is usually where the backend of the nodes is implemented. 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 js code for custom extensions. This is usually where you add your own custom ui elements. 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/
