This repository provides a set of custom nodes for ComfyUI that enable 'broadcast' or 'virtual link' functionality. Instead of manually connecting every node input, users can connect data to an 'Anything Everywhere' node, which then automatically routes that data to any unconnected input of the same type across the workflow. This dramatically reduces visual clutter and simplifies complex workflows. The system supports advanced filtering via regex, group/color restrictions, priority resolution, and subgraph compatibility. It also includes a 'Combo Clone' node for broadcasting dropdown values and a 'Seed Everywhere' node for seed synchronization. The architecture is split between Python backend node definitions (in `use_everywhere.py`) and a rich JavaScript frontend that handles graph analysis, virtual link rendering, and user interface. The core logic resides in the JS modules: `use_everywhere_graph_analysis.js` analyzes the graph to determine which inputs can be connected, `use_everywhere_classes.js` models the broadcast links, and `use_everywhere_ui.js` renders the virtual connections with animations and highlights. The system integrates deeply with ComfyUI's graph lifecycle, intercepting prompt submission to temporarily convert virtual links into real links for execution. Key entry points include the Python node classes (`AnythingEverywhere`, `ComboClone`, etc.) and the JavaScript extension registration in `use_everywhere.js`. The primary data flow is: user connects data to a UE node → graph analysis identifies matching unconnected inputs → virtual links are stored in graph metadata → on prompt, virtual links are materialized as real links → after execution, links are removed. External dependencies are minimal: it relies on ComfyUI's frontend package and standard web APIs.
The LLM identified 3 files worth highlighting for reuse:
Provides a Logger class with configurable log levels (ERROR, PROBLEM, INFORMATION, DETAIL) and a Pausable base class for managing pause/resume state. The Logger is self-contained and can be reused in any JavaScript project for structured logging. The Pausable pattern is a clean way to prevent reentrant or overlapping operations, useful in event-driven systems.
Defines the UseEverywhere and UseEverywhereList classes that model a single broadcast link and a collection of links. UseEverywhere encapsulates the source, control node, type, restrictions, and matching logic. UseEverywhereList manages all broadcasts and provides methods to find best matches, detect ambiguities, and enumerate connections. This is a well-designed domain model that could be extracted for any system needing rule-based connection routing.
Implements the GraphAnalyser class that traverses a ComfyUI graph to identify all UE nodes and unconnected inputs, then matches them using the UseEverywhereList. It also handles temporary graph modification (converting virtual links to real links) for prompt execution. The analysis is incremental and cached, with pause/resume support. This module demonstrates a sophisticated approach to dynamic graph rewriting and could serve as a reference for similar systems.
