libSQL API for JavaScript/TypeScript

libSQL is an open source, open contribution fork of SQLite. This source repository contains libSQL API bindings for Node, which aims to be compatible with better-sqlite3, but with opt-in promise API.

Please note that there is also the libSQL SDK, which is useful if you don't need better-sqlite3 compatibility or use libSQL in environments like serverless functions that require fetch()-based database access protocol.

Features

In-memory and local libSQL/SQLite databases
Remote libSQL databases
Embedded, in-app replica that syncs with a remote libSQL database
Supports Bun, Deno, and Node on macOS, Linux, and Windows.

Installing

You can install the package with:

Node:

npm i libsql

Bun:

bun add libsql

Deno:

Use the npm: prefix for package import:

import Database from 'npm:libsql';

API reference

Getting Started

To try out your first libsql program, type the following in hello.js:

import Database from 'libsql';

const db = new Database(':memory:');

db.exec("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)");
db.exec("INSERT INTO users (id, name, email) VALUES (1, 'Alice', 'alice@example.org')");

const row = db.prepare("SELECT * FROM users WHERE id = ?").get(1);

console.log(`Name: ${row.name}, email: ${row.email}`);

and then run:

$ node hello.js

To use the promise API, import libsql/promise:

import Database from 'libsql/promise';

const db = new Database(':memory:');

await db.exec("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT)");
await db.exec("INSERT INTO users (id, name, email) VALUES (1, 'Alice', 'alice@example.org')");

const stmt = await db.prepare("SELECT * FROM users WHERE id = ?");
const row = stmt.get(1);

console.log(`Name: ${row.name}, email: ${row.email}`);

Connecting to a local database file

import Database from 'libsql';

const db = new Database('hello.db');

Connecting to a Remote libSQL server

import Database from 'libsql';

const url = process.env.LIBSQL_URL;
const authToken = process.env.LIBSQL_AUTH_TOKEN;

const opts = {
  authToken: authToken,
};

const db = new Database(url, opts);

Creating an in-app replica and syncing it

import libsql

const opts = { syncUrl: "<url>", authToken: "<optional auth token>" };
const db = new Database('hello.db', opts);
db.sync();

Creating a table

db.exec("CREATE TABLE users (id INTEGER, email TEXT);")

Inserting rows into a table

db.exec("INSERT INTO users VALUES (1, 'alice@example.org')")

Querying rows from a table

const row = db.prepare("SELECT * FROM users WHERE id = ?").get(1);

Developing

To build the libsql package, run:

LIBSQL_JS_DEV=1 npm run build

You can then run the integration tests with:

export LIBSQL_JS_DEV=1
npm link
cd integration-tests
npm link libsql
npm test
