看看Cassandra Node.js driver。
下面是一个示例代码，向您展示如何连接到Amazon Keyspaces：

const cassandra = require('cassandra-driver');
const fs = require('fs');
const auth = new cassandra.auth.PlainTextAuthProvider('ServiceUserName', 'ServicePassword');
const sslOptions1 = {
    ca: [
        fs.readFileSync('path_to_file/sf-class2-root.crt', 'utf-8')],      
            host: 'cassandra.us-west-2.amazonaws.com',
                rejectUnauthorized: true
        };
const client = new cassandra.Client({
    contactPoints: ['cassandra.us-west-2.amazonaws.com'],
        localDataCenter: 'us-west-2',
        authProvider: auth,
        sslOptions: sslOptions1,
        protocolOptions: { port: 9142 }
    });

const query = 'SELECT * FROM system_schema.keyspaces';
 
client.execute(query)
    .then( result => console.log('Row from Keyspaces %s', result.rows[0]))
    .catch( e=> console.log(`${e}`));
