+# Settings System
+
+## Overview
+
+ComfyUI frontend uses a comprehensive settings system for user preferences with support for dynamic defaults, version-based rollouts, and environment-aware configuration.
+
+### Settings Architecture
+- Settings are defined as `SettingParams` in `src/constants/coreSettings.ts`
+- Registered at app startup, loaded/saved via `useSettingStore` (Pinia)
+- Persisted per user via backend `/settings` endpoint
+- If a value hasn't been set by the user, the store returns the computed default
+
+```typescript
+// From src/stores/settingStore.ts:105-122
+function getDefaultValue<K extends keyof Settings>(
+  key: K
+): Settings[K] | undefined {
+  const param = getSettingById(key)
+  if (param === undefined) return
+
+  const versionedDefault = getVersionedDefaultValue(key, param)
+  if (versionedDefault) {
+    return versionedDefault
+  }
+
+  return typeof param.defaultValue === 'function'
+    ? param.defaultValue()
+    : param.defaultValue
+}
+```
+
+### Settings Registration Process
+
+Settings are registered after server values are loaded:
+
+```typescript
+// From src/components/graph/GraphCanvas.vue:311-315
+CORE_SETTINGS.forEach((setting) => {
+  settingStore.addSetting(setting)
+})
+
+await newUserService().initializeIfNewUser(settingStore)
+```
+
+## Dynamic and Environment-Based Defaults
+
+### Computed Defaults
+You can compute defaults dynamically using function defaults that access runtime context:
+
+```typescript
+// From src/constants/coreSettings.ts:94-101
+{
+  id: 'Comfy.Sidebar.Size',
+  // Default to small if the window is less than 1536px(2xl) wide
+  defaultValue: () => (window.innerWidth < 1536 ? 'small' : 'normal')
+}
+```
+
+```typescript
+// From src/constants/coreSettings.ts:306
+{
+  id: 'Comfy.Locale',
+  defaultValue: () => navigator.language.split('-')[0] || 'en'
+}
+```
+
+### Version-Based Defaults
+You can vary defaults by installed frontend version using `defaultsByInstallVersion`:
+
+```typescript
+// From src/stores/settingStore.ts:129-150
+function getVersionedDefaultValue<K extends keyof Settings, TValue = Settings[K]>(
+  key: K, 
+  param: SettingParams<TValue> | undefined
+): TValue | null {
+  const defaultsByInstallVersion = param?.defaultsByInstallVersion
+  if (defaultsByInstallVersion && key !== 'Comfy.InstalledVersion') {
+    const installedVersion = get('Comfy.InstalledVersion')
+    if (installedVersion) {
+      const sortedVersions = Object.keys(defaultsByInstallVersion).sort(
+        (a, b) => compareVersions(b, a)
+      )
+      for (const version of sortedVersions) {
+        if (!isSemVer(version)) continue
+        if (compareVersions(installedVersion, version) >= 0) {
+          const versionedDefault = defaultsByInstallVersion[version]
+          return typeof versionedDefault === 'function'
+            ? versionedDefault()
+            : versionedDefault
+        }
+      }
+    }
+  }
+  return null
+}
+```
+
+Example versioned defaults from codebase:
+
+```typescript
+// From src/constants/coreSettings.ts:38-40
+{
+  id: 'Comfy.Graph.LinkReleaseAction',
+  defaultValue: LinkReleaseTriggerAction.CONTEXT_MENU,
+  defaultsByInstallVersion: {
+    '1.24.1': LinkReleaseTriggerAction.SEARCH_BOX
+  }
+}
+
+// Another versioned default example
+{
+  id: 'Comfy.Graph.LinkReleaseAction.Shift',
+  defaultValue: LinkReleaseTriggerAction.SEARCH_BOX,
+  defaultsByInstallVersion: {
+    '1.24.1': LinkReleaseTriggerAction.CONTEXT_MENU
+  }
+}
+```
+
+### Real Examples from Codebase
+
+Here are actual settings showing different patterns:
+
+```typescript
+// Number setting with validation
+{
+  id: 'LiteGraph.Node.TooltipDelay',
+  name: 'Tooltip Delay',
+  type: 'number',
+  attrs: {
+    min: 100,
+    max: 3000,
+    step: 50
+  },
+  defaultValue: 500,
+  versionAdded: '1.9.0'
+}
+
+// Hidden system setting for tracking
+{
+  id: 'Comfy.InstalledVersion',
+  name: 'The frontend version that was running when the user first installed ComfyUI',
+  type: 'hidden',
+  defaultValue: null,
+  versionAdded: '1.24.0'
+}
+
+// Slider with complex tooltip
+{
+  id: 'LiteGraph.Canvas.LowQualityRenderingZoomThreshold',
+  name: 'Low quality rendering zoom threshold',
+  tooltip: 'Zoom level threshold for performance mode. Lower values (0.1) = quality at all zoom levels. Higher values (1.0) = performance mode even when zoomed in.',
+  type: 'slider',
+  attrs: {
+    min: 0.1,
+    max: 1.0,
+    step: 0.05
+  },
+  defaultValue: 0.5
+}
+```
+
+### New User Version Capture
+
+The initial installed version is captured for new users to ensure versioned defaults remain stable:
+
+```typescript
+// From src/services/newUserService.ts:49-53
+await settingStore.set(
+  'Comfy.InstalledVersion',
+  __COMFYUI_FRONTEND_VERSION__
+)
+```
+
+## Practical Patterns for Environment-Based Defaults
+
+### Dynamic Default Patterns
+```typescript
+// Device-based default
+{
+  id: 'Comfy.Example.MobileDefault',
+  type: 'boolean',
+  defaultValue: () => /Mobile/i.test(navigator.userAgent)
+}
+
+// Environment-based default
+{
+  id: 'Comfy.Example.DevMode',
+  type: 'boolean',
+  defaultValue: () => import.meta.env.DEV
+}
+
+// Window size based
+{
+  id: 'Comfy.Example.CompactUI',
+  type: 'boolean',
+  defaultValue: () => window.innerWidth < 1024
+}
+```
+
+### Version-Based Rollout Pattern
+```typescript
+{
+  id: 'Comfy.Example.NewFeature',
+  type: 'combo',
+  options: ['legacy', 'enhanced'],
+  defaultValue: 'legacy',
+  defaultsByInstallVersion: {
+    '1.25.0': 'enhanced'
+  }
+}
+```
+
+## Settings Persistence and Access
+
+### API Interaction
+Values are stored per user via the backend. The store writes through API and falls back to defaults when not set:
+
+```typescript
+// From src/stores/settingStore.ts:73-75
+onChange(settingsById.value[key], newValue, oldValue)
+settingValues.value[key] = newValue
+await api.storeSetting(key, newValue)
+```
+
+### Usage in Components
+```typescript
+const settingStore = useSettingStore()
+
+// Get setting value (returns computed default if not set by user)
+const value = settingStore.get('Comfy.SomeSetting')
+
+// Update setting value
+await settingStore.set('Comfy.SomeSetting', newValue)
+```
+
+
+## Advanced Settings Features
+
+### Migration and Backward Compatibility
+
+Settings support migration from deprecated values:
+
+```typescript
+// From src/stores/settingStore.ts:68-69, 172-175
+const newValue = tryMigrateDeprecatedValue(
+  settingsById.value[key],
+  clonedValue
+)
+
+// Migration happens during addSetting for existing values:
+if (settingValues.value[setting.id] !== undefined) {
+  settingValues.value[setting.id] = tryMigrateDeprecatedValue(
+    setting,
+    settingValues.value[setting.id]
+  )
+}
+```
+
+### onChange Callbacks
+
+Settings can define onChange callbacks that receive the setting definition, new value, and old value:
+
+```typescript
+// From src/stores/settingStore.ts:73, 177
+onChange(settingsById.value[key], newValue, oldValue)  // During set()
+onChange(setting, get(setting.id), undefined)         // During addSetting()
+```
+
+### Settings UI and Categories
+
+Settings are automatically grouped for UI based on their `category` or derived from `id`:
+
+```typescript
+{
+  id: 'Comfy.Sidebar.Size',
+  category: ['Appearance', 'Sidebar', 'Size'],
+  // UI will group this under Appearance > Sidebar > Size
+}
+```
+
+## Related Documentation
+
+- Feature flag system: `docs/FEATURE_FLAGS.md`
+- Settings schema for backend: `src/schemas/apiSchema.ts` (zSettings)
+- Server configuration (separate from user settings): `src/constants/serverConfig.ts`
+
+## Summary
+
+- **Settings**: User preferences with dynamic/versioned defaults, persisted per user
+- **Environment Defaults**: Use function defaults to read runtime context (window, navigator, env)
+- **Version Rollouts**: Use `defaultsByInstallVersion` for gradual feature releases
+- **API Interaction**: Settings persist to `/settings` endpoint via `storeSetting()`

-When deciding between these approaches, consider:
+### Service Pattern Comparison
 
-1. **Stateful vs. Stateless**: For stateful services, classes often provide clearer encapsulation
-2. **Reactivity needs**: If the service needs to be reactive, composable-style services integrate better with Vue's reactivity system
-3. **Complexity**: For complex services with many methods and internal state, classes can provide better organization
-4. **Testing**: Both approaches can be tested effectively, but composables may be simpler to test with Vue Test Utils
+| Aspect | Class-Based Services | Composable-Style Services | Bootstrap Services | Shared State Services |
+|--------|---------------------|---------------------------|-------------------|---------------------|
+| **Count** | 4 services | 18+ services | 1 service | 1 service |
+| **Export Pattern** | `export class ServiceName` | `export function useServiceName()` | `export function setupX()` | `export function serviceFactory()` |
+| **Instantiation** | `new ServiceName(data)` | `useServiceName()` | Direct function call | Direct function call |
+| **Best For** | Complex data structures, search algorithms, expensive initialization | Vue integration, API calls, reactive state | One-time app initialization | Singleton-like shared state |
+| **State Management** | Encapsulated private/public properties | External stores + reactive refs | Event listeners, side effects | Module-level state |
+| **Vue Integration** | Manual integration needed | Native reactivity support | N/A | Varies |
+| **Examples** | `NodeSearchService`, `Load3dService` | `workflowService`, `dialogService` | `autoQueueService` | `newUserService` |
+
+### Decision Criteria
+
+When choosing between these approaches, consider:
+
+1. **Data Structure Complexity**: Classes work well for services managing multiple related data structures (search indices, filters, complex state)
+2. **Initialization Cost**: Classes are ideal when expensive setup should happen once and be controlled by instantiation
+3. **Vue Integration**: Composables integrate seamlessly with Vue's reactivity system and stores
+4. **API Interactions**: Composables handle async operations and API calls more naturally
+5. **State Management**: Classes provide strong encapsulation; composables work better with external state management
+6. **Application Bootstrap**: Bootstrap services handle one-time app initialization, event listener setup, and side effects
+7. **Singleton Behavior**: Shared state services provide module-level state that persists across multiple function calls
+
+**Current Usage Patterns:**
+- **Class-based services (4)**: Complex data processing, search algorithms, expensive initialization
+- **Composable-style services (18+)**: UI interactions, API calls, store integration, reactive state management
+- **Bootstrap services (1)**: One-time application initialization and event handler setup
+- **Shared state services (1)**: Singleton-like behavior with module-level state management

+## Testing Services
+
+Services in ComfyUI can be tested effectively using different approaches depending on their implementation pattern.
+
+### Testing Class-Based Services
+
+**Setup Requirements:**
+```typescript
+// Manual instantiation required
+const mockData = [/* test data */]
+const service = new NodeSearchService(mockData)
+```
+
+**Characteristics:**
+- Requires constructor argument preparation
+- State is encapsulated within the class instance
+- Direct method calls on the instance
+- Good isolation - each test gets a fresh instance
+
+**Example:**
+```typescript
+describe('NodeSearchService', () => {
+  let service: NodeSearchService
+
+  beforeEach(() => {
+    const mockNodes = [/* mock node definitions */]
+    service = new NodeSearchService(mockNodes)
+  })
+
+  test('should search nodes by query', () => {
+    const results = service.searchNode('test query')
+    expect(results).toHaveLength(2)
+  })
+
+  test('should apply filters correctly', () => {
+    const filters = [{ filterDef: service.inputTypeFilter, value: 'IMAGE' }]
+    const results = service.searchNode('*', filters)
+    expect(results.every(node => /* has IMAGE input */)).toBe(true)
+  })
+})
+```
+
+### Testing Composable-Style Services
+
+**Setup Requirements:**
+```typescript
+// Direct function call, no instantiation
+const { saveWorkflow, loadWorkflow } = useWorkflowService()
+```
+
+**Characteristics:**
+- No instantiation needed
+- Integrates naturally with Vue Test Utils
+- Easy mocking of reactive dependencies
+- External store dependencies need mocking
+
+**Example:**
+```typescript
+describe('useWorkflowService', () => {
+  beforeEach(() => {
+    // Mock external dependencies
+    vi.mock('@/stores/settingStore', () => ({
+      useSettingStore: () => ({
+        get: vi.fn().mockReturnValue(true),
+        set: vi.fn()
+      })
+    }))
+
+    vi.mock('@/stores/toastStore', () => ({
+      useToastStore: () => ({
+        add: vi.fn()
+      })
+    }))
+  })
+
+  test('should save workflow with prompt', async () => {
+    const { saveWorkflow } = useWorkflowService()
+    await saveWorkflow('test-workflow')
+
+    // Verify interactions with mocked dependencies
+    expect(mockSettingStore.get).toHaveBeenCalledWith('Comfy.PromptFilename')
+  })
+})
+```
+
+### Testing Bootstrap Services
+
+**Focus on Setup Behavior:**
+```typescript
+describe('autoQueueService', () => {
+  beforeEach(() => {
+    // Mock global dependencies
+    vi.mock('@/scripts/api', () => ({
+      api: {
+        addEventListener: vi.fn()
+      }
+    }))
+
+    vi.mock('@/scripts/app', () => ({
+      app: {
+        queuePrompt: vi.fn()
+      }
+    }))
+  })
+
+  test('should setup event listeners', () => {
+    setupAutoQueueHandler()
+
+    expect(mockApi.addEventListener).toHaveBeenCalledWith('graphChanged', expect.any(Function))
+  })
+
+  test('should handle graph changes when auto-queue enabled', () => {
+    setupAutoQueueHandler()
+
+    // Simulate graph change event
+    const graphChangeHandler = mockApi.addEventListener.mock.calls[0][1]
+    graphChangeHandler()
+
+    expect(mockApp.queuePrompt).toHaveBeenCalled()
+  })
+})
+```
+
+### Testing Shared State Services
+
+**Focus on Shared State Behavior:**
+```typescript
+describe('newUserService', () => {
+  beforeEach(() => {
+    // Reset module state between tests
+    vi.resetModules()
+  })
+
+  test('should return consistent API across calls', () => {
+    const service1 = newUserService()
+    const service2 = newUserService()
+
+    // Same functions returned (shared behavior)
+    expect(service1.isNewUser).toBeDefined()
+    expect(service2.isNewUser).toBeDefined()
+  })
+
+  test('should share state between service instances', async () => {
+    const service1 = newUserService()
+    const service2 = newUserService()
+
+    // Initialize through one instance
+    const mockSettingStore = { set: vi.fn() }
+    await service1.initializeIfNewUser(mockSettingStore)
+
+    // State should be shared
+    expect(service2.isNewUser()).toBe(true) // or false, depending on mock
+  })
+})
+```
+
+### Common Testing Patterns
+
+**Mocking External Dependencies:**
+```typescript
+// Mock stores
+vi.mock('@/stores/settingStore', () => ({
+  useSettingStore: () => ({
+    get: vi.fn(),
+    set: vi.fn()
+  })
+}))
+
+// Mock API calls
+vi.mock('@/scripts/api', () => ({
+  api: {
+    get: vi.fn().mockResolvedValue({ data: 'mock' }),
+    post: vi.fn().mockResolvedValue({ success: true })
+  }
+}))
+
+// Mock Vue composables
+vi.mock('vue', () => ({
+  ref: vi.fn((val) => ({ value: val })),
+  reactive: vi.fn((obj) => obj)
+}))
+```
+
+**Async Testing:**
+```typescript
+test('should handle async operations', async () => {
+  const service = useMyService()
+  const result = await service.performAsyncOperation()
+  expect(result).toBeTruthy()
+})
+
+test('should handle concurrent requests', async () => {
+  const service = useMyService()
+  const promises = [
+    service.loadData('key1'),
+    service.loadData('key2')
+  ]
+
+  const results = await Promise.all(promises)
+  expect(results).toHaveLength(2)
+})
+```
+
+**Error Handling:**
+```typescript
+test('should handle service errors gracefully', async () => {
+  const service = useMyService()
+
+  // Mock API to throw error
+  mockApi.get.mockRejectedValue(new Error('Network error'))
+
+  await expect(service.fetchData()).rejects.toThrow('Network error')
+})
+
+test('should provide meaningful error messages', async () => {
+  const service = useMyService()
+  const consoleSpy = vi.spyOn(console, 'error').mockImplementation()
+
+  await service.handleError('test error')
+
+  expect(consoleSpy).toHaveBeenCalledWith(expect.stringContaining('test error'))
+})
+```
+
+### Testing Best Practices
+
+1. **Isolate Dependencies**: Always mock external dependencies (stores, APIs, DOM)
+2. **Reset State**: Use `beforeEach` to ensure clean test state
+3. **Test Error Paths**: Don't just test happy paths - test error scenarios
+4. **Mock Timers**: Use `vi.useFakeTimers()` for time-dependent services
+5. **Test Async Properly**: Use `async/await` and proper promise handling
+

+## ComfyUI-Specific Patterns
+
+ComfyUI stores follow additional patterns specific to the application's architecture:
+
+### WebSocket Message Handling
+
+Many stores handle real-time updates via WebSocket messages. The execution store is a prime example:
+
+```typescript
+import { defineStore } from 'pinia'
+import { ref } from 'vue'
+import type { ExecutionStartWsMessage, ProgressWsMessage } from '@/schemas/apiSchema'
+import { api } from '@/scripts/api'
+
+export const useExecutionStore = defineStore('execution', () => {
+  const activePromptId = ref<string | null>(null)
+  const nodeProgressStates = ref<Record<string, NodeProgressState>>({})
+
+  // Register WebSocket event listeners
+  function registerEvents() {
+    api.addEventListener('execution_start', handleExecutionStart)
+    api.addEventListener('progress', handleProgress)
+    api.addEventListener('execution_error', handleExecutionError)
+  }
+
+  function handleExecutionStart(e: CustomEvent<ExecutionStartWsMessage>) {
+    activePromptId.value = e.detail.prompt_id
+    // Handle execution start
+  }
+
+  function handleProgress(e: CustomEvent<ProgressWsMessage>) {
+    // Update node progress states
+    const { value, max } = e.detail
+    // ... progress handling logic
+  }
+
+  // Clean up listeners when store is no longer needed
+  function unregisterEvents() {
+    api.removeEventListener('execution_start', handleExecutionStart)
+    api.removeEventListener('progress', handleProgress)
+    api.removeEventListener('execution_error', handleExecutionError)
+  }
+
+  return {
+    activePromptId,
+    nodeProgressStates,
+    registerEvents,
+    unregisterEvents
+  }
+})
+```
+
+### Store Communication Patterns
+
+ComfyUI stores frequently reference each other to maintain consistency across the application:
+
+```typescript
+import { defineStore } from 'pinia'
+import { computed } from 'vue'
+import { useCanvasStore } from './graphStore'
+import { useWorkflowStore } from './workflowStore'
+
+export const useExecutionStore = defineStore('execution', () => {
+  // Reference related stores
+  const workflowStore = useWorkflowStore()
+  const canvasStore = useCanvasStore()
+
+  // Computed values that depend on other stores
+  const activeWorkflow = computed(() => workflowStore.activeWorkflow)
+  
+  // Actions that coordinate between stores
+  async function executeWorkflow() {
+    const workflow = workflowStore.serialize()
+    const canvas = canvasStore.canvas
+    // Execute with coordination between stores
+  }
+
+  return {
+    activeWorkflow,
+    executeWorkflow
+  }
+})
+```
+
+### Extension Integration
+
+Extensions can register with stores to extend functionality:
+
+```typescript
+import { defineStore } from 'pinia'
+import { ref } from 'vue'
+import type { ComfyExtension } from '@/types/comfy'
+
+export const useExtensionStore = defineStore('extension', () => {
+  const extensionByName = ref<Record<string, ComfyExtension>>({})
+
+  function registerExtension(extension: ComfyExtension) {
+    if (!extension.name) {
+      throw new Error("Extensions must have a 'name' property.")
+    }
+
+    if (extensionByName.value[extension.name]) {
+      console.warn(`Extension ${extension.name} already registered. Overwriting.`)
+    }
+
+    extensionByName.value[extension.name] = extension
+
+    // Call extension setup if provided
+    if (extension.setup) {
+      extension.setup()
+    }
+  }
+
+  function isExtensionEnabled(extensionName: string): boolean {
+    const extension = extensionByName.value[extensionName]
+    return extension && !extension.disabled
+  }
+
+  return {
+    extensionByName: readonly(extensionByName),
+    registerExtension,
+    isExtensionEnabled
+  }
+})
+```
+
+### Workspace Store Organization
+
+ComfyUI uses a two-tier store organization:
+
+1. **Main stores** (`src/stores/*.ts`) - Core application logic
+2. **Workspace stores** (`src/stores/workspace/*.ts`) - UI layout and workspace-specific state
+
+The `useWorkspaceStore` acts as a coordinator, providing computed access to other stores:
+
+```typescript
+import { defineStore } from 'pinia'
+import { computed } from 'vue'
+import { useWorkflowStore } from './workflowStore'
+import { useBottomPanelStore } from './workspace/bottomPanelStore'
+import { useSidebarTabStore } from './workspace/sidebarTabStore'
+
+export const useWorkspaceStore = defineStore('workspace', () => {
+  const focusMode = ref(false)
+
+  // Provide unified access to related stores
+  const workflow = computed(() => useWorkflowStore())
+  const sidebarTab = computed(() => useSidebarTabStore())
+  const bottomPanel = computed(() => useBottomPanelStore())
+
+  // Workspace-level actions that coordinate multiple stores
+  function toggleFocusMode() {
+    focusMode.value = !focusMode.value
+    // Hide/show panels based on focus mode
+    if (focusMode.value) {
+      bottomPanel.value.hide()
+      sidebarTab.value.closeTabs()
+    }
+  }
+
+  return {
+    focusMode,
+    workflow,
+    sidebarTab,
+    bottomPanel,
+    toggleFocusMode
+  }
+})
+```
+
+### Node and Workflow State Management
+
+ComfyUI stores often work with node and workflow concepts:
+
+```typescript
+import { defineStore } from 'pinia'
+import { ref, computed } from 'vue'
+import type { ComfyWorkflow, NodeId } from '@/schemas/comfyWorkflowSchema'
+
+export const useWorkflowStore = defineStore('workflow', () => {
+  const activeWorkflow = ref<ComfyWorkflow | null>(null)
+
+  // Convert node ID to a locator for cross-store communication
+  function nodeIdToNodeLocatorId(nodeId: NodeId): NodeLocatorId {
+    return createNodeLocatorId(activeWorkflow.value?.path, nodeId)
+  }
+
+  // Serialize current workflow for execution
+  function serialize(): ComfyApiWorkflow {
+    if (!activeWorkflow.value) {
+      throw new Error('No active workflow to serialize')
+    }
+    return convertToApiFormat(activeWorkflow.value)
+  }
+
+  return {
+    activeWorkflow,
+    nodeIdToNodeLocatorId,
+    serialize
+  }
+})
+```
+
+These patterns ensure that ComfyUI stores work together effectively to manage the complex state of a node-based workflow editor.
