-# Absurd SQL - Cursor Development Guide
-
-## Project Overview
-Absurd SQL is a backend implementation for sql.js that enables persistent SQLite databases in the browser by using IndexedDB as a block storage system. This guide provides rules and best practices for developing with this project in Cursor.
-
-## Project Structure
-```
-absurd-sql/
-├── src/               # Source code
-├── dist/             # Built files
-├── package.json      # Dependencies and scripts
-├── rollup.config.js  # Build configuration
-└── jest.config.js    # Test configuration
-```
-
-## Development Rules
-
-### 1. Worker Thread Requirements
-- All SQL operations MUST be performed in a worker thread
-- Main thread should only handle worker initialization and communication
-- Never block the main thread with database operations
-
-### 2. Code Organization
-- Keep worker code in separate files (e.g., `*.worker.js`)
-- Use ES modules for imports/exports
-- Follow the project's existing module structure
-
-### 3. Required Headers
-When developing locally or deploying, ensure these headers are set:
-```
-Cross-Origin-Opener-Policy: same-origin
-Cross-Origin-Embedder-Policy: require-corp
-```
-
-### 4. Browser Compatibility
-- Primary target: Modern browsers with SharedArrayBuffer support
-- Fallback mode: Safari (with limitations)
-- Always test in both modes
-
-### 5. Database Configuration
-Recommended database settings:
-```sql
-PRAGMA journal_mode=MEMORY;
-PRAGMA page_size=8192;  -- Optional, but recommended
-```
-
-### 6. Development Workflow
-1. Install dependencies:
-   ```bash
-   yarn add @jlongster/sql.js absurd-sql
-   ```
-
-2. Development commands:
-   - `yarn build` - Build the project
-   - `yarn jest` - Run tests
-   - `yarn serve` - Start development server
-
-### 7. Testing Guidelines
-- Write tests for both SharedArrayBuffer and fallback modes
-- Use Jest for testing
-- Include performance benchmarks for critical operations
-
-### 8. Performance Considerations
-- Use bulk operations when possible
-- Monitor read/write performance
-- Consider using transactions for multiple operations
-- Avoid unnecessary database connections
-
-### 9. Error Handling
-- Implement proper error handling for:
-  - Worker initialization failures
-  - Database connection issues
-  - Concurrent access conflicts (in fallback mode)
-  - Storage quota exceeded scenarios
-
-### 10. Security Best Practices
-- Never expose database operations directly to the client
-- Validate all SQL queries
-- Implement proper access controls
-- Handle sensitive data appropriately
-
-### 11. Code Style
-- Follow ESLint configuration
-- Use async/await for asynchronous operations
-- Document complex database operations
-- Include comments for non-obvious optimizations
-
-### 12. Debugging
-- Use `jest-debug` for debugging tests
-- Monitor IndexedDB usage in browser dev tools
-- Check worker communication in console
-- Use performance monitoring tools
-
-## Common Patterns
-
-### Worker Initialization
-```javascript
-// Main thread
-import { initBackend } from 'absurd-sql/dist/indexeddb-main-thread';
-
-function init() {
-  let worker = new Worker(new URL('./index.worker.js', import.meta.url));
-  initBackend(worker);
-}
-```
-
-### Database Setup
-```javascript
-// Worker thread
-import initSqlJs from '@jlongster/sql.js';
-import { SQLiteFS } from 'absurd-sql';
-import IndexedDBBackend from 'absurd-sql/dist/indexeddb-backend';
-
-async function setupDatabase() {
-  let SQL = await initSqlJs({ locateFile: file => file });
-  let sqlFS = new SQLiteFS(SQL.FS, new IndexedDBBackend());
-  SQL.register_for_idb(sqlFS);
-  
-  SQL.FS.mkdir('/sql');
-  SQL.FS.mount(sqlFS, {}, '/sql');
-  
-  return new SQL.Database('/sql/db.sqlite', { filename: true });
-}
-```
-
-## Troubleshooting
-
-### Common Issues
-1. SharedArrayBuffer not available
-   - Check COOP/COEP headers
-   - Verify browser support
-   - Test fallback mode
-
-2. Worker initialization failures
-   - Check file paths
-   - Verify module imports
-   - Check browser console for errors
-
-3. Performance issues
-   - Monitor IndexedDB usage
-   - Check for unnecessary operations
-   - Verify transaction usage

-## 1. Overview
-wa-sqlite is a WebAssembly build of SQLite that enables SQLite database operations in web browsers and JavaScript environments. It provides both synchronous and asynchronous builds, with support for custom virtual file systems (VFS) for persistent storage.
-
-## 2. Installation
-```bash
-npm install wa-sqlite
-# or
-yarn add wa-sqlite
-```
-
-## 3. Basic Setup
-
-### 3.1 Import and Initialize
-```javascript
-// Choose one of these imports based on your needs:
-// - wa-sqlite.mjs: Synchronous build
-// - wa-sqlite-async.mjs: Asynchronous build (required for async VFS)
-// - wa-sqlite-jspi.mjs: JSPI-based async build (experimental, Chromium only)
-import SQLiteESMFactory from 'wa-sqlite/dist/wa-sqlite.mjs';
-import * as SQLite from 'wa-sqlite';
-
-async function initDatabase() {
-  // Initialize SQLite module
-  const module = await SQLiteESMFactory();
-  const sqlite3 = SQLite.Factory(module);
-  
-  // Open database (returns a Promise)
-  const db = await sqlite3.open_v2('myDatabase');
-  return { sqlite3, db };
-}
-```
-
-### 3.2 Basic Database Operations
-```javascript
-async function basicOperations() {
-  const { sqlite3, db } = await initDatabase();
-  
-  try {
-    // Create a table
-    await sqlite3.exec(db, `
-      CREATE TABLE IF NOT EXISTS users (
-        id INTEGER PRIMARY KEY,
-        name TEXT NOT NULL,
-        email TEXT UNIQUE
-      )
-    `);
-    
-    // Insert data
-    await sqlite3.exec(db, `
-      INSERT INTO users (name, email) 
-      VALUES ('John Doe', 'john@example.com')
-    `);
-    
-    // Query data
-    const results = [];
-    await sqlite3.exec(db, 'SELECT * FROM users', (row, columns) => {
-      results.push({ row, columns });
-    });
-    
-    return results;
-  } finally {
-    // Always close the database when done
-    await sqlite3.close(db);
-  }
-}
-```
-
-## 4. Virtual File Systems (VFS)
-
-### 4.1 Available VFS Options
-wa-sqlite provides several VFS implementations for persistent storage:
-
-1. **IDBBatchAtomicVFS** (Recommended for general use)
-   - Uses IndexedDB with batch atomic writes
-   - Works in all contexts (Window, Worker, Service Worker)
-   - Supports WAL mode
-   - Best performance with `PRAGMA synchronous=normal`
-
-2. **IDBMirrorVFS**
-   - Keeps files in memory, persists to IndexedDB
-   - Works in all contexts
-   - Good for smaller databases
-
-3. **OPFS-based VFS** (Origin Private File System)
-   - Various implementations available:
-     - AccessHandlePoolVFS
-     - OPFSAdaptiveVFS
-     - OPFSCoopSyncVFS
-     - OPFSPermutedVFS
-   - Better performance but limited to Worker contexts
-
-### 4.2 Using a VFS
-```javascript
-import { IDBBatchAtomicVFS } from 'wa-sqlite/src/examples/IDBBatchAtomicVFS.js';
-import SQLiteESMFactory from 'wa-sqlite/dist/wa-sqlite-async.mjs';
-import * as SQLite from 'wa-sqlite';
-
-async function initDatabaseWithVFS() {
-  const module = await SQLiteESMFactory();
-  const sqlite3 = SQLite.Factory(module);
-  
-  // Register VFS
-  const vfs = await IDBBatchAtomicVFS.create('myApp', module);
-  sqlite3.vfs_register(vfs, true);
-  
-  // Open database with VFS
-  const db = await sqlite3.open_v2('myDatabase');
-  
-  // Configure for better performance
-  await sqlite3.exec(db, 'PRAGMA synchronous = normal');
-  await sqlite3.exec(db, 'PRAGMA journal_mode = WAL');
-  
-  return { sqlite3, db };
-}
-```
-
-## 5. Best Practices
-
-### 5.1 Error Handling
-```javascript
-async function safeDatabaseOperation() {
-  const { sqlite3, db } = await initDatabase();
-  
-  try {
-    await sqlite3.exec(db, 'SELECT * FROM non_existent_table');
-  } catch (error) {
-    if (error.code === SQLite.SQLITE_ERROR) {
-      console.error('SQL error:', error.message);
-    } else {
-      console.error('Database error:', error);
-    }
-  } finally {
-    await sqlite3.close(db);
-  }
-}
-```
-
-### 5.2 Transaction Management
-```javascript
-async function transactionExample() {
-  const { sqlite3, db } = await initDatabase();
-  
-  try {
-    await sqlite3.exec(db, 'BEGIN TRANSACTION');
-    
-    // Perform multiple operations
-    await sqlite3.exec(db, 'INSERT INTO users (name) VALUES (?)', ['Alice']);
-    await sqlite3.exec(db, 'INSERT INTO users (name) VALUES (?)', ['Bob']);
-    
-    await sqlite3.exec(db, 'COMMIT');
-  } catch (error) {
-    await sqlite3.exec(db, 'ROLLBACK');
-    throw error;
-  } finally {
-    await sqlite3.close(db);
-  }
-}
-```
-
-### 5.3 Prepared Statements
-```javascript
-async function preparedStatementExample() {
-  const { sqlite3, db } = await initDatabase();
-  
-  try {
-    // Prepare statement
-    const stmt = await sqlite3.prepare(db, 'SELECT * FROM users WHERE id = ?');
-    
-    // Execute with different parameters
-    await sqlite3.bind(stmt, 1, 1);
-    while (await sqlite3.step(stmt) === SQLite.SQLITE_ROW) {
-      const row = sqlite3.row(stmt);
-      console.log(row);
-    }
-    
-    // Reset and reuse
-    await sqlite3.reset(stmt);
-    await sqlite3.bind(stmt, 1, 2);
-    // ... execute again
-    
-    await sqlite3.finalize(stmt);
-  } finally {
-    await sqlite3.close(db);
-  }
-}
-```
-
-## 6. Performance Considerations
-
-1. **VFS Selection**
-   - Use IDBBatchAtomicVFS for general-purpose applications
-   - Consider OPFS-based VFS for better performance in Worker contexts
-   - Use MemoryVFS for temporary databases
-
-2. **Configuration**
-   - Set appropriate page size (default is usually fine)
-   - Use WAL mode for better concurrency
-   - Consider `PRAGMA synchronous=normal` for better performance
-   - Adjust cache size based on your needs
-
-3. **Concurrency**
-   - Use transactions for multiple operations
-   - Be aware of VFS-specific concurrency limitations
-   - Consider using Web Workers for heavy database operations
-
-## 7. Common Issues and Solutions
-
-1. **Database Locking**
-   - Use appropriate transaction isolation levels
-   - Implement retry logic for busy errors
-   - Consider using WAL mode
-
-2. **Storage Limitations**
-   - Be aware of browser storage quotas
-   - Implement cleanup strategies
-   - Monitor database size
-
-3. **Cross-Context Access**
-   - Use appropriate VFS for your context
-   - Consider message passing for cross-context communication
-   - Be aware of storage access limitations
-
-## 8. TypeScript Support
-wa-sqlite includes TypeScript definitions. The main types are:
-
-```typescript
-type SQLiteCompatibleType = number | string | Uint8Array | Array<number> | bigint | null;
-
-interface SQLiteAPI {
-  open_v2(filename: string, flags?: number, zVfs?: string): Promise<number>;
-  exec(db: number, sql: string, callback?: (row: any[], columns: string[]) => void): Promise<number>;
-  close(db: number): Promise<number>;
-  // ... other methods
-}
-```

-async function importToAbsurdSql(data: MigrationData): Promise<void> {
-  await db.exec('BEGIN TRANSACTION;');
-  try {
-    // Import accounts
-    for (const account of data.accounts) {
-      await db.run(`
-        INSERT INTO accounts (did, public_key_hex, created_at, updated_at)
-        VALUES (?, ?, ?, ?)
-      `, [account.did, account.publicKeyHex, account.createdAt, account.updatedAt]);
-    }
-    
-    // Import settings
-    for (const setting of data.settings) {
-      await db.run(`
-        INSERT INTO settings (key, value, updated_at)
-        VALUES (?, ?, ?)
-      `, [setting.key, setting.value, setting.updatedAt]);
-    }
-    
-    // Import contacts
-    for (const contact of data.contacts) {
-      await db.run(`
-        INSERT INTO contacts (id, did, name, created_at, updated_at)
-        VALUES (?, ?, ?, ?, ?)
-      `, [contact.id, contact.did, contact.name, contact.createdAt, contact.updatedAt]);
-    }
-    await db.exec('COMMIT;');
-  } catch (error) {
-    await db.exec('ROLLBACK;');
-    throw error;
-  }
-}
-```
-
-### 3. Verification
-```typescript
-async function verifyMigration(dexieData: MigrationData): Promise<boolean> {
-  // Verify account count
-  const accountResult = await db.exec('SELECT COUNT(*) as count FROM accounts');
-  const accountCount = accountResult[0].values[0][0];
-  if (accountCount !== dexieData.accounts.length) {
-    return false;
-  }
-  
-  // Verify settings count
-  const settingsResult = await db.exec('SELECT COUNT(*) as count FROM settings');
-  const settingsCount = settingsResult[0].values[0][0];
-  if (settingsCount !== dexieData.settings.length) {
-    return false;
-  }
-  
-  // Verify contacts count
-  const contactsResult = await db.exec('SELECT COUNT(*) as count FROM contacts');
-  const contactsCount = contactsResult[0].values[0][0];
-  if (contactsCount !== dexieData.contacts.length) {
-    return false;
-  }
-  
-  // Verify data integrity
-  for (const account of dexieData.accounts) {
-    const result = await db.exec(
-      'SELECT * FROM accounts WHERE did = ?',
-      [account.did]
-    );
-    const migratedAccount = result[0]?.values[0];
-    if (!migratedAccount || 
-        migratedAccount[1] !== account.publicKeyHex) { // public_key_hex is second column
-      return false;
-    }
-  }
-  
-  return true;
-}
-```
-
-## Performance Considerations
-
-### 1. Indexing
-- Dexie automatically creates indexes based on the schema
-- absurd-sql requires explicit index creation
-- Added indexes for frequently queried fields
-- Use `PRAGMA journal_mode=MEMORY;` for better performance
-
-### 2. Batch Operations
-- Dexie has built-in bulk operations
-- absurd-sql uses transactions for batch operations
-- Consider chunking large datasets
-- Use prepared statements for repeated queries
-
-### 3. Query Optimization
-- Dexie uses IndexedDB's native indexing
-- absurd-sql requires explicit query optimization
-- Use prepared statements for repeated queries
-- Consider using `PRAGMA synchronous=NORMAL;` for better performance
-
-## Error Handling
-
-### 1. Common Errors
-```typescript
-// Dexie errors
-try {
-  await db.accounts.add(account);
-} catch (error) {
-  if (error instanceof Dexie.ConstraintError) {
-    // Handle duplicate key
-  }
-}
-
-// absurd-sql errors
-try {
-  await db.run(`
-    INSERT INTO accounts (did, public_key_hex, created_at, updated_at)
-    VALUES (?, ?, ?, ?)
-  `, [account.did, account.publicKeyHex, account.createdAt, account.updatedAt]);
-} catch (error) {
-  if (error.message.includes('UNIQUE constraint failed')) {
-    // Handle duplicate key
-  }
-}
-```
-
-### 2. Transaction Recovery
-```typescript
-// Dexie transaction
-try {
-  await db.transaction('rw', db.accounts, async () => {
-    // Operations
-  });
-} catch (error) {
-  // Dexie automatically rolls back
-}
-
-// absurd-sql transaction
-try {
-  await db.exec('BEGIN TRANSACTION;');
-  // Operations
-  await db.exec('COMMIT;');
-} catch (error) {
-  await db.exec('ROLLBACK;');
-  throw error;
-}
-```
-

-## Implementation Details
-
-### Web Platform (absurd-sql)
-
-The web implementation uses absurd-sql with the following features:
-
-1. **Web Worker Support**
-   - SQLite operations run in a dedicated worker thread
-   - Main thread remains responsive
-   - SharedArrayBuffer support when available
-   - Worker initialization in `sqlite.worker.ts`
-
-2. **IndexedDB Backend**
-   - Persistent storage using IndexedDB

-   - Configurable performance settings
-
-Example configuration:
-```typescript
-const webConfig: SQLiteConfig = {
-  name: 'timesafari',
-  useWAL: true,
-  useMMap: typeof SharedArrayBuffer !== 'undefined',
-  mmapSize: 30000000000,
-  usePreparedStatements: true,
-  maxPreparedStatements: 100
-};
-```
-
-### Mobile Platform (Capacitor SQLite)

-  id TEXT PRIMARY KEY,
-  did TEXT NOT NULL,
-  name TEXT,
-  created_at INTEGER NOT NULL,
-  updated_at INTEGER NOT NULL,
-  FOREIGN KEY (did) REFERENCES accounts(did)
-);
-
--- Performance indexes
-CREATE INDEX idx_accounts_created_at ON accounts(created_at);
-CREATE INDEX idx_contacts_did ON contacts(did);
-CREATE INDEX idx_settings_updated_at ON settings(updated_at);
-```
-
