# Storage Migration Guide
|
||||
|
||||
## Overview
|
||||
|
||||
CodeForge has migrated from Spark KV-based storage to **IndexedDB** as the primary local database solution. This provides:
|
||||
|
||||
- ✅ **Better Performance**: Structured queries with indexes
|
||||
- ✅ **More Storage**: No 10MB limit like LocalStorage
|
||||
- ✅ **Structured Data**: Organized collections instead of flat key-value
|
||||
- ✅ **Offline First**: Robust offline capabilities
|
||||
- ✅ **Backward Compatible**: Spark KV still available as fallback
|
||||
|
||||
## Architecture
|
||||
|
||||
### Storage Layers
|
||||
|
||||
```
|
||||

┌─────▼──────┐ ┌─────▼──────┐
|
||||
│ IndexedDB │ │ Spark KV │
|
||||
│ (Primary) │ │ (Fallback) │
|
||||
└────────────┘ └────────────┘
|
||||
```
|
||||
|
||||
### IndexedDB Schema
|
||||
|
||||
```typescript
|
||||
{
|
||||
projects: {
|
||||
id: string,
|
||||
name: string,
|
||||
files: any[],
|
||||
models: any[],
|
||||
// ... full project data
|
||||
},
|
||||
files: {
|
||||
id: string,
|
||||
name: string,
|
||||
content: string,
|
||||
language: string,
|
||||
},
|
||||
models: {
|
||||
id: string,
|
||||
name: string,
|
||||
fields: any[],
|
||||
},
|
||||
components: {
|
||||
id: string,
|
||||
name: string,
|
||||
code: string,
|
||||
},
|
||||
workflows: {
|
||||
id: string,
|
||||
name: string,
|
||||
nodes: any[],
|
||||
edges: any[],
|
||||
},
|
||||
settings: {
|
||||
key: string,
|
||||
value: any,
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### Basic Storage Hook
|
||||
|
||||
Replace `useKV` from Spark with `useStorage`:
|
||||
|
||||
```typescript
|
||||
// ❌ Old way (Spark KV only)
|
||||
import { useKV } from '@github/spark/hooks'
|
||||
const [todos, setTodos] = useKV('todos', [])
|
||||
|
||||
// ✅ New way (IndexedDB + Spark KV fallback)
|
||||
import { useStorage } from '@/hooks/use-storage'
|
||||
const [todos, setTodos] = useStorage('todos', [])
|
||||
```
|
||||
|
||||
### Collection-Based Storage
|
||||
|
||||
For structured data collections:
|
||||
|
||||
```typescript
|
||||
import { useIndexedDB } from '@/hooks/use-indexed-db'
|
||||
|
||||
// Single item by ID
|
||||
const [project, updateProject, deleteProject, loading] =
|
||||
useIndexedDB('projects', projectId, defaultProject)
|
||||
|
||||
// All items in collection
|
||||
const [allProjects, refresh, loading] =
|
||||
useIndexedDBCollection('projects')
|
||||
```
|
||||
|
||||
### Direct Database Access
|
||||
|
||||
For advanced queries:
|
||||
|
||||
```typescript
|
||||
import { db } from '@/lib/db'
|
||||
|
||||
// Get by ID
|
||||
const project = await db.get('projects', 'proj-123')
|
||||
|
||||
// Get all
|
||||
const allProjects = await db.getAll('projects')
|
||||
|
||||
// Query by index
|
||||
const recentProjects = await db.query(
|
||||
'projects',
|
||||
'updatedAt',
|
||||
IDBKeyRange.lowerBound(Date.now() - 7 * 24 * 60 * 60 * 1000)
|
||||
)
|
||||
|
||||
// Save
|
||||
await db.put('projects', {
|
||||
id: 'proj-123',
|
||||
name: 'My Project',
|
||||
// ...
|
||||
})
|
||||
|
||||
// Delete
|
||||
await db.delete('projects', 'proj-123')
|
||||
```
|
||||
|
||||
## Migration
|
||||
|
||||
### Automatic Migration
|
||||
|
||||
The hybrid storage system automatically handles migration:
|
||||
|
||||
1. On first read, checks IndexedDB
|
||||
2. If not found, checks Spark KV
|
||||
3. On write, saves to both (if enabled)
|
||||
|
||||
### Manual Migration
|
||||
|
||||
Use the Storage Settings page or programmatically:
|
||||
|
||||
```typescript
|
||||
import { storage } from '@/lib/storage'
|
||||
|
||||
// Migrate all data from Spark KV to IndexedDB
|
||||
const { migrated, failed } = await storage.migrateFromSparkKV()
|
||||
console.log(`Migrated ${migrated} items, ${failed} failed`)
|
||||
|
||||
// Sync IndexedDB back to Spark KV (backup)
|
||||
const { synced, failed } = await storage.syncToSparkKV()
|
||||
console.log(`Synced ${synced} items, ${failed} failed`)
|
||||
```
|
||||
|
||||
### Storage Settings UI
|
||||
|
||||
Access via Settings → Storage Management:
|
||||
|
||||
- **View Statistics**: See item counts in each storage
|
||||
- **Migrate Data**: One-click migration from Spark KV
|
||||
- **Sync to Cloud**: Backup IndexedDB to Spark KV
|
||||
- **Clear Data**: Emergency data reset
|
||||
|
||||
## Configuration
|
||||
|
||||
### Storage Options
|
||||
|
||||
```typescript
|
||||
import { HybridStorage } from '@/lib/storage'
|
||||
|
||||
// Custom configuration
|
||||
const customStorage = new HybridStorage({
|
||||
useIndexedDB: true, // Enable IndexedDB
|
||||
useSparkKV: true, // Enable Spark KV fallback
|
||||
preferIndexedDB: true, // Try IndexedDB first
|
||||
})
|
||||
```
|
||||
|
||||
### Pre-configured Instances
|
||||
|
||||
```typescript
|
||||
import {
|
||||
storage, // Default: IndexedDB preferred, Spark KV fallback
|
||||
indexedDBOnlyStorage, // IndexedDB only
|
||||
sparkKVOnlyStorage // Spark KV only
|
||||
} from '@/lib/storage'
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. Use Functional Updates
|
||||
|
||||
Always use functional updates for concurrent-safe operations:
|
||||
|
||||
```typescript
|
||||
// ❌ Wrong - stale closure
|
||||
setTodos([...todos, newTodo])
|
||||
|
||||
// ✅ Correct - always current
|
||||
setTodos((current) => [...current, newTodo])
|
||||
```
|
||||
|
||||
### 2. Structured Data in Collections
|
||||
|
||||
Store structured data in typed collections:
|
||||
|
||||
```typescript
|
||||
// ❌ Wrong - flat key-value
|
||||
await storage.set('project-123', projectData)
|
||||
|
||||
// ✅ Correct - structured collection
|
||||
await db.put('projects', {
|
||||
id: '123',
|
||||
...projectData
|
||||
})
|
||||
```
|
||||
|
||||
### 3. Error Handling
|
||||
|
||||
Always handle storage errors gracefully:
|
||||
|
||||
```typescript
|
||||
try {
|
||||
await updateProject(newData)
|
||||
} catch (error) {
|
||||
console.error('Failed to save project:', error)
|
||||
toast.error('Save failed. Please try again.')
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Periodic Backups
|
||||
|
||||
Regularly sync to Spark KV for backup:
|
||||
|
||||
```typescript
|
||||
// Backup on significant changes
|
||||
useEffect(() => {
|
||||
if (hasUnsavedChanges) {
|
||||
storage.syncToSparkKV().catch(console.error)
|
||||
}
|
||||
}, [hasUnsavedChanges])
|
||||
```
|
||||
|
||||
## Performance Benefits
|
||||
|
||||
### Before (Spark KV Only)
|
||||
|
||||
- 🐌 Linear search through all keys
|
||||
- 🐌 No indexes or structured queries
|
||||
- 🐌 Serialization overhead on every access
|
||||
- ⚠️ 10MB storage limit
|
||||
|
||||
### After (IndexedDB Primary)
|
||||
|
||||
- ⚡ Indexed queries (O(log n))
|
||||
- ⚡ Structured collections with schemas
|
||||
- ⚡ Efficient binary storage
|
||||
- ✅ ~1GB+ storage (browser dependent)
|
||||
|
||||
## Browser Support
|
||||
|
||||
IndexedDB is supported in all modern browsers:
|
||||
|
||||
- ✅ Chrome 24+
|
||||
- ✅ Firefox 16+
|
||||
- ✅ Safari 10+
|
||||
- ✅ Edge 12+
|
||||
- ✅ Mobile browsers
|
||||
|
||||
Spark KV automatically serves as fallback if IndexedDB is unavailable.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### "Database not initialized" Error
|
||||
|
||||
```typescript
|
||||
// Ensure init is called before use
|
||||
await db.init()
|
||||
const data = await db.get('projects', 'proj-123')
|
||||
```
|
||||
|
||||
### Storage Quota Exceeded
|
||||
|
||||
```typescript
|
||||
// Check available storage
|
||||
if (navigator.storage && navigator.storage.estimate) {
|
||||
const { usage, quota } = await navigator.storage.estimate()
|
||||
console.log(`Using ${usage} of ${quota} bytes`)
|
||||
}
|
||||
```
|
||||
|
||||
### Data Migration Issues
|
||||
|
||||
1. Check browser console for specific errors
|
||||
2. Verify Spark KV data exists: `window.spark.kv.keys()`
|
||||
3. Clear IndexedDB and retry migration
|
||||
4. Use Storage Settings UI for guided migration
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
- [ ] **Remote Sync**: Sync to cloud database
|
||||
- [ ] **Compression**: Compress large datasets
|
||||
- [ ] **Encryption**: Encrypt sensitive data at rest
|
||||
- [ ] **Import/Export**: JSON export for portability
|
||||
- [ ] **Version Control**: Track data changes over time
|
||||
|
||||
## Summary
|
||||
|
||||
The migration to IndexedDB provides:
|
||||
|
||||
1. **Better Performance**: Structured queries with indexes
|
||||
2. **More Capacity**: Gigabytes instead of megabytes
|
||||
3. **Backward Compatible**: Spark KV still works
|
||||
4. **Easy Migration**: One-click data transfer
|
||||
5. **Flexible**: Use IndexedDB, Spark KV, or both
|
||||
|
||||
The hybrid storage system ensures your data is always accessible while providing the performance benefits of a proper database.
