Connect Your Application

Choose a KalamDB SDK and connect your application to the database you started in the quickstart.

Choose a KalamDB SDK

For TypeScript:

1npm install @kalamdb/client

1import { Auth, createClient } from '@kalamdb/client';2 3const client = createClient({4  url: 'http://localhost:2900',5  authProvider: async () => Auth.jwt(accessToken),6});7 8console.log(await client.query('SELECT CURRENT_USER()'));

accessToken is an access token obtained through your application’s authentication flow. See token authentication. Keep administrator credentials on the server; client applications should use the signed-in user’s token.

Common mistakes

The query runs as the authenticated user. If a USER table looks empty, confirm that the writer and reader use the same identity. Creating a table is an administrative operation; do it through your schema workflow.
