## __Main ComfyApp Functions__ import { app, ComfyApp } from "../../scripts/app.js";

### __Application Management__

- `setup(canvasEl)` - Initializes the application on the page, loads extensions, registers nodes
- `resizeCanvas()` - Adjusts canvas size to window
- `clean()` - Clears application state (node outputs, image previews, errors)

### __Workflow Management__

- `loadGraphData(graphData, clean, restore_view, workflow, options)` - Loads workflow data from JSON
- `loadApiJson(apiData, fileName)` - Loads workflow from API format
- `graphToPrompt(graph, options)` - Converts graph to prompt for execution
- `handleFile(file)` - Handles file loading (PNG, WebP, JSON, MP3, MP4, SVG, etc.)

### __Execution__

- `queuePrompt(number, batchCount, queueNodeIds)` - Queues prompt for execution
- `registerNodes()` - Registers node definitions from backend
- `registerNodeDef(nodeId, nodeDef)` - Registers single node definition
- `refreshComboInNodes()` - Refreshes combo lists in nodes

### __Node Management__

- `registerExtension(extension)` - Registers ComfyUI extension
- `updateVueAppNodeDefs(defs)` - Updates node definitions in Vue app
- `revokePreviews(nodeId)` - Frees memory for node previews

### __Clipboard__

- `copyToClipspace(node)` - Copies node to clipboard
- `pasteFromClipspace(node)` - Pastes data from clipboard to node

### __Position Conversion__

- `clientPosToCanvasPos(pos)` - Converts client position to canvas position
- `canvasPosToClientPos(pos)` - Converts canvas position to client position

### __Error Handling__

- `showErrorOnFileLoad(file)` - Displays file loading error
- `#showMissingNodesError(missingNodeTypes)` - Shows missing nodes error
- `#showMissingModelsError(missingModels, paths)` - Shows missing models error

### __Internal Handlers__

- `#addDropHandler()` - Handles drag and drop of files
- `#addProcessKeyHandler()` - Handles keyboard input
- `#addDrawNodeHandler()` - Modifies node drawing behavior
- `#addApiUpdateHandlers()` - Handles API updates
- `#addConfigureHandler()` - Graph configuration flag
- `#addAfterConfigureHandler()` - Post-configuration handling

### __Deprecated Properties__

Many properties are marked as deprecated and redirect to appropriate stores:

- `lastNodeErrors` → `useExecutionStore().lastNodeErrors`
- `lastExecutionError` → `useExecutionStore().lastExecutionError`
- `runningNodeId` → `useExecutionStore().executingNodeId`
- `shiftDown` → `useWorkspaceStore().shiftDown`
- `widgets` → `useWidgetStore().widgets`
- `extensions` → `useExtensionStore().extensions`

### __Utility Functions__

- `sanitizeNodeName(string)` - Cleans node name from dangerous characters
- `getPreviewFormatParam()` - Returns preview format parameter
- `getRandParam()` - Returns random parameter for refresh
- `isApiJson(data)` - Checks if data is in API JSON format

This application uses Vue and TypeScript composition pattern, where many functionalities are separated into different services and stores (e.g., `useExecutionStore`, `useWorkflowService`, `useExtensionService`, etc.).
