In this JavaScript quickstart we will learn how to:
  • Retrieve database credentials
  • Install the JavaScript libSQL client
  • Connect to a remote Turso database
  • Execute a query using SQL
1

Retrieve database credentials

You will need an existing database to continue. If you don’t have one, create one.Get the database URL:
turso db show --url <database-name>
Get the database authentication token:
turso db tokens create <database-name>
Assign credentials to the environment variables inside .env.
TURSO_DATABASE_URL= TURSO_AUTH_TOKEN=
You will want to store these as environment variables.
2

Install @libsql/client

Begin by installing the @libsql/client dependency in your project:
npm install @libsql/client
3

Initialize a new client

Next add your database URL and auth token:
import { createClient } from "@libsql/client";  export const turso = createClient({  url: process.env.TURSO_DATABASE_URL,  authToken: process.env.TURSO_AUTH_TOKEN, });
4

Execute a query using SQL

You can execute a SQL query against your existing database by calling execute():
await turso.execute("SELECT * FROM users");
If you need to use placeholders for values, you can do that:
await turso.execute({  sql: "SELECT * FROM users WHERE id = ?",  args: [1], });
