---

About

This package is the Turso in-memory database library for JavaScript.

⚠️ Warning: This software is ALPHA, only use for development, testing, and experimentation. We are working to make it production ready, but do not use it for critical data right now.

Features

• SQLite compatible: SQLite query language and file format support (status).
• In-process: No network overhead, runs directly in your Node.js process
• TypeScript support: Full TypeScript definitions included
• Cross-platform: Supports Linux, macOS, Windows and browsers (through WebAssembly)

Installation

npm install @tursodatabase/database

Getting Started

In-Memory Database

import { connect } from '@tursodatabase/database';

// Create an in-memory database
const db = await connect(':memory:');

// Create a table
db.exec('CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)');

// Insert data
const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
insert.run('Alice', 'alice@example.com');
insert.run('Bob', 'bob@example.com');

// Query data
const users = db.prepare('SELECT * FROM users').all();
console.log(users);
// Output: [
//   { id: 1, name: 'Alice', email: 'alice@example.com' },
//   { id: 2, name: 'Bob', email: 'bob@example.com' }
// ]

File-Based Database

import { connect } from '@tursodatabase/database';

// Create or open a database file
const db = await connect('my-database.db');

// Create a table
db.exec(`
  CREATE TABLE IF NOT EXISTS posts (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    title TEXT NOT NULL,
    content TEXT,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
  )
`);

// Insert a post
const insertPost = db.prepare('INSERT INTO posts (title, content) VALUES (?, ?)');
const result = insertPost.run('Hello World', 'This is my first blog post!');

console.log(`Inserted post with ID: ${result.lastInsertRowid}`);

Transactions

import { connect } from '@tursodatabase/database';

const db = await connect('transactions.db');

// Using transactions for atomic operations
const transaction = db.transaction((users) => {
  const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
  for (const user of users) {
    insert.run(user.name, user.email);
  }
});

// Execute transaction
transaction([
  { name: 'Alice', email: 'alice@example.com' },
  { name: 'Bob', email: 'bob@example.com' }
]);

Turso Database can run in browsers using WebAssembly. Check the browser.js and WASM artifacts for browser usage.
