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.
