Migrating Node.js driver

Complete the following procedure to migrate your existing DataStax Node.js driver to a version that is capable of connecting to Astra DB databases created using DataStax Astra DB.

Install the DataStax Node.js driver:
- DataStax Node.js driver for Apache Cassandra
- DSE driver
npm install cassandra-driver
npm install dse-driver

In your existing DataStax Node.js driver code, modify the connection code to use the Astra DB API. Include the absolute path to the secure connect bundle for your Cassandra database (secure-connect-database_name.zip) in the secureConnectBundle parameter, as shown in the following examples.

DataStax Node.js driver for Apache Cassandra
DSE Node.js driver

const { Client } = require('cassandra-driver');
const client = new Client({
    cloud: { secureConnectBundle: 'path/to/secure-connect-database_name.zip' },
    credentials: { username: 'clientId', password: 'clientSecret' }
  });

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

const client = new Client({
    cloud: { secureConnectBundle: 'path/to/secure-connect-database_name.zip' },
    credentials: { username: 'clientId', password: 'clientSecret' }
  });

Run your Node.js script to connect to your Astra DB database:

node my_node.js_driver.js

If successful, the code builds, compiles, and connects to your Cassandra database.
