6. **Complex State**: Use `useArray`, `useMap`, or `useSet` for advanced data structures
7. **Session Management**: Use `useSessionStorage` for authentication and user session tracking
## Session & Storage Hooks
### useSessionStorage
Manages user sessions with IndexedDB persistence and automatic activity tracking.
```tsx
import { useSessionStorage } from '@/hooks'
const {
sessionId, // Current session ID
isLoading, // Loading state
createSession, // Create new session
destroySession, // End current session
getAllSessions, // Get all sessions
clearAllSessions, // Clear all sessions
updateSession, // Update activity
restoreSession // Restore from storage
} = useSessionStorage()
// Sessions automatically:
// - Restore on page load
// - Update activity every 60 seconds
// - Expire after 24 hours
// - Integrate with Redux auth state
```
### useIndexedDBState
React state hook with IndexedDB persistence - like `useState` but data survives page refreshes.
```tsx
import { useIndexedDBState } from '@/hooks'
const [preferences, setPreferences, deletePreferences] = useIndexedDBState(
'userPreferences',
{ theme: 'light', language: 'en' }
)
// Use like useState
setPreferences({ theme: 'dark', language: 'en' })
// Functional updates
setPreferences(prev => ({ ...prev, theme: 'dark' }))
// Delete and reset to default
deletePreferences()
```
### useIndexedDBCache
Cached data fetching with automatic TTL-based refresh and IndexedDB persistence.
```tsx
import { useIndexedDBCache } from '@/hooks'
const { data, isLoading, error, refresh } = useIndexedDBCache(
'apiData',
async () => {
const response = await fetch('/api/data')
return response.json()
},
5 * 60 * 1000 // Cache for 5 minutes
)
// Data cached in IndexedDB
// Refetches if cache older than TTL
// Call refresh() to force fetch
```
See [INDEXED_DB.md](../lib/INDEXED_DB.md) for complete IndexedDB documentation.

# IndexedDB Session & State Management
This module provides a comprehensive IndexedDB wrapper for managing user sessions and application state with persistence across browser sessions.
## Features
- **Session Management**: Store and manage user authentication sessions with automatic expiry
- **Activity Tracking**: Track user activity and update session timestamps
- **App State Persistence**: Store arbitrary application state with timestamps
- **Automatic Cleanup**: Expired sessions are automatically detected and removed
- **React Hooks**: Easy-to-use React hooks for session and state management
## Core API
### IndexedDB Manager
The `IndexedDBManager` class provides low-level access to IndexedDB storage.
```typescript
import { indexedDB } from '@/lib/indexed-db'
```
#### Session Methods
```typescript
// Save a new session
const sessionId = await indexedDB.saveSession({
userId: 'user-123',
email: 'user@example.com',
name: 'John Doe',
role: 'Admin',
currentEntity: 'Main Agency',
expiresAt: Date.now() + (24 * 60 * 60 * 1000) // 24 hours
})
// Get a specific session
const session = await indexedDB.getSession(sessionId)
// Get the most recent active session
const currentSession = await indexedDB.getCurrentSession()
// Update session activity timestamp
await indexedDB.updateSessionActivity(sessionId)
// Delete a session
await indexedDB.deleteSession(sessionId)
// Get all sessions
const allSessions = await indexedDB.getAllSessions()
// Clear all sessions
await indexedDB.clearAllSessions()
```
#### App State Methods
```typescript
// Save app state
await indexedDB.saveAppState('userPreferences', {
theme: 'dark',
language: 'en',
notifications: true
})
// Get app state
const preferences = await indexedDB.getAppState<UserPreferences>('userPreferences')
// Delete app state
await indexedDB.deleteAppState('userPreferences')
// Clear all app state
await indexedDB.clearAppState()
```
## React Hooks
### useSessionStorage
Manages user sessions with automatic persistence and restoration.
```typescript
import { useSessionStorage } from '@/hooks/use-session-storage'
function MyComponent() {
const {
sessionId, // Current session ID
isLoading, // Loading state during initialization
createSession, // Create a new session
destroySession, // End the current session
updateSession, // Update activity timestamp
getAllSessions, // Get all sessions
clearAllSessions, // Clear all sessions
restoreSession // Restore session from storage
} = useSessionStorage()
// Sessions are automatically:
// - Created when user logs in
// - Restored on page load
// - Updated every 60 seconds while active
// - Updated when page is closed
}
```
**Features:**
- Automatic session restoration on app load
- Activity tracking with configurable intervals (default: 60 seconds)
- Session expiry (default: 24 hours)
- Integration with Redux auth state
- Beforeunload event handling
### useIndexedDBState
React state hook with IndexedDB persistence.
```typescript
import { useIndexedDBState } from '@/hooks/use-indexed-db-state'
function MyComponent() {
const [preferences, setPreferences, deletePreferences] = useIndexedDBState(
'userPreferences',
{ theme: 'light', language: 'en' }
)
// Works like useState but persists to IndexedDB
setPreferences({ theme: 'dark', language: 'en' })
// Or use functional updates
setPreferences(prev => ({ ...prev, theme: 'dark' }))
// Delete from storage and reset to default
deletePreferences()
}
```
### useIndexedDBCache
Cached data fetching with TTL support.
```typescript
import { useIndexedDBCache } from '@/hooks/use-indexed-db-state'
function MyComponent() {
const { data, isLoading, error, refresh } = useIndexedDBCache(
'apiData',
async () => {
const response = await fetch('/api/data')
return response.json()
},
5 * 60 * 1000 // Cache for 5 minutes
)
// Data is cached in IndexedDB
// Automatically refetches if cache is older than TTL
// Call refresh() to force a new fetch
}
```
## UI Components
### SessionManager
A complete UI for managing user sessions.
```typescript
import { SessionManager } from '@/components/SessionManager'
function ProfilePage() {
return (
<div>
<SessionManager />
</div>
)
}
```
**Features:**
- View all active sessions
- See last activity time and login time
- End individual sessions
- End all other sessions (keep current)
- Clear all sessions
## Session Data Structure
```typescript
interface SessionData {
id: string // Unique session identifier
userId: string // User ID
email: string // User email
name: string // User name
role: string // User role
roleId?: string // Optional role ID
avatarUrl?: string // Optional avatar URL
permissions?: string[] // Optional permissions array
currentEntity: string // Current organizational entity
loginTimestamp: number // When session was created
lastActivityTimestamp: number // Last activity time
expiresAt?: number // Optional expiry timestamp
}
```
## Best Practices
1. **Always use functional updates** with `useIndexedDBState`:
```typescript
// ✅ CORRECT
setState(prev => ({ ...prev, newValue }))
// ❌ WRONG - state may be stale
setState({ ...state, newValue })
```
2. **Set appropriate TTLs** for cached data:
```typescript
// Frequently changing data
useIndexedDBCache('realtimeData', fetcher, 30 * 1000) // 30 seconds
// Rarely changing data
useIndexedDBCache('staticData', fetcher, 60 * 60 * 1000) // 1 hour
```
3. **Handle errors gracefully**:
```typescript
try {
await indexedDB.saveSession(sessionData)
} catch (error) {
console.error('Failed to save session:', error)
// Fallback to in-memory session
}
```
4. **Clean up sessions** when appropriate:
```typescript
// On logout
await destroySession()
// On account deletion
await clearAllSessions()
```
## Browser Support
IndexedDB is supported in all modern browsers:
- Chrome 24+
- Firefox 16+
- Safari 10+
- Edge 12+
## Storage Limits
IndexedDB storage limits vary by browser:
- Chrome: ~60% of available disk space
- Firefox: ~50% of available disk space
- Safari: 1GB (asks user for more)
The module handles quota exceeded errors gracefully.
## Security Considerations
1. **Data is stored locally** on the user's device
2. **Not encrypted by default** - don't store sensitive data
3. **Clear sessions** on logout to prevent unauthorized access
4. **Set appropriate expiry times** to limit session lifetime
5. **Validate session data** when restoring from storage
## Migration from localStorage
If you're migrating from localStorage:
```typescript
// Before (localStorage)
const data = JSON.parse(localStorage.getItem('key') || '{}')
localStorage.setItem('key', JSON.stringify(data))
// After (IndexedDB)
const [data, setData] = useIndexedDBState('key', {})
setData(newData)
```
## Debugging
Enable IndexedDB debugging in Chrome DevTools:
1. Open DevTools
2. Go to Application tab
3. Expand IndexedDB
4. Select "WorkForceProDB"
5. View "sessions" and "appState" stores
## Performance
- **Initial load**: ~10-50ms
- **Read operations**: ~5-20ms
- **Write operations**: ~10-30ms
- **Bulk operations**: Batched for optimal performance
## Future Enhancements
Potential improvements for future versions:
- Encryption support for sensitive data
- Sync between tabs using BroadcastChannel
- Migration utilities for schema changes
- Compression for large data
- Export/import functionality
