Turso Serverless Driver for JavaScript

---

About

A serverless database driver for Turso Cloud, using only fetch(). Connect to your database from serverless and edge functions, such as Cloudflare Workers and Vercel.

📝 Note: This driver is experimental and, therefore, subject to change at any time.

Installation

npm install @tursodatabase/serverless

Getting Started

Basic Usage

import { connect } from "@tursodatabase/serverless";

const conn = connect({
  url: process.env.TURSO_DATABASE_URL,
  authToken: process.env.TURSO_AUTH_TOKEN,
});

// Prepare a statement
const stmt = conn.prepare("SELECT * FROM users WHERE id = ?");

// Get first row
const row = await stmt.get([123]);
console.log(row);

// Get all rows
const rows = await stmt.all([123]);
console.log(rows);

// Iterate through rows (streaming)
for await (const row of stmt.iterate([123])) {
  console.log(row);
}

Batch Operations

// Execute multiple statements in a batch
await conn.batch([
  "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, email TEXT)",
  "INSERT INTO users (email) VALUES ('user@example.com')",
  "INSERT INTO users (email) VALUES ('admin@example.com')",
]);

libSQL Compatibility Layer

For existing libSQL applications, use the compatibility layer:

import { createClient } from "@tursodatabase/serverless/compat";

const client = createClient({
  url: process.env.TURSO_DATABASE_URL,
  authToken: process.env.TURSO_AUTH_TOKEN,
});

// Execute a single SQL statement
const result = await client.execute("SELECT * FROM users WHERE id = ?", [123]);
console.log(result.rows);

// Execute multiple statements in a batch
await client.batch([
  "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, email TEXT)",
  "INSERT INTO users (email) VALUES ('user@example.com')",
  "INSERT INTO users (email) VALUES ('admin@example.com')",
]);
