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
-
Download your database’s Secure Connect Bundle (SCB).
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.
