ComfyUI Frontend Extensions

Custom nodes can extend the ComfyUI frontend with JavaScript. Extensions register hooks, widgets, commands, settings, and UI components.

Quick Start

1. Export WEB_DIRECTORY in Python

# __init__.py
WEB_DIRECTORY = "./js"
__all__ = ["WEB_DIRECTORY"]

2. Create JavaScript Extension

// js/my_extension.js
import { app } from "../../scripts/app.js";
