JavaScript API reference

This document describes the JavaScript API for Turso. The API is implemented in two different packages:

• bindings/javascript: Native bindings for the Turso database.
• packages/turso-serverless: Serverless driver for Turso Cloud databases.

The API is compatible with the libSQL promise API, which is an asynchronous variant of the better-sqlite3 API.
