Connect the Node.js driver to your database

This driver doesn’t support the vector data type.

DataStax recommends CQL drivers only for Serverless (Non-Vector) databases, existing applications that previously used a CQL-based driver, or if you plan to exclusively use CQL.

It is possible to use CQL drivers for non-vector data in Serverless (Vector) databases. However, DataStax recommends the Data API and clients for Serverless (Vector) databases.

Initialize the Node.js driver to connect to your database.

Prerequisites

Connect

This code configures the Node.js driver with an SCB and authentication details, then establishes a connection to the database through an asynchronous run function.

const cassandra = require('cassandra-driver');

const cloud = { secureConnectBundle: process.env['ASTRA_DB_SECURE_BUNDLE_PATH'] };
const authProvider = new cassandra.auth.PlainTextAuthProvider('token', process.env['ASTRA_DB_APPLICATION_TOKEN']);
const client = new cassandra.Client({ cloud, authProvider });

async function run() {
    await client.connect();

    // ...
}

See the Node.js quickstart for details on how to install the package, connect to a Serverless (Vector) database, create a table and vector-compatible SAI (Storage-Attached Index), load data, and perform a similarity search.
