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
await 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 (?, ?)');
await insert.run('Alice', '[e-mail]');
await insert.run('Bob', '[e-mail]');

// Query data
const users = await db.prepare('SELECT * FROM users').all();
console.log(users);
// Output: [
//   { id: 1, name: 'Alice', email: '[e-mail]' },
//   { id: 2, name: 'Bob', email: '[e-mail]' }
// ]

File-Based Database

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

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

// Create a table
await 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 = await 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(async (users) => {
  const insert = db.prepare('INSERT INTO users (name, email) VALUES (?, ?)');
  for (const user of users) {
    await insert.run(user.name, user.email);
  }
});

// Execute transaction
await transaction([
  { name: 'Alice', email: '[e-mail]' },
  { name: 'Bob', email: '[e-mail]' }
]);
