# Couchbase Node.js SDK 4.4

# Couchbase Node.js SDK 4.4

```javascript
const queryResult = await cluster.query(
    "SELECT * FROM `travel-sample`.inventory.hotel WHERE city=$1 LIMIT 10",
    { parameters: ['Paris']}
);
queryResult.rows.forEach((row)=>{
   console.log(row);
});
```

The Node.js SDK allows you to connect to a Couchbase Server cluster from Node.js. The Node.js SDK is a native Node.js module that uses the very fast Couchbase++ library to handle communicating with the cluster over the Couchbase binary protocol.

This page covers using our operational Node.js SDK to connect to the Analytics Service of a Capella Operational or self-managed Couchbase Server cluster. As well as this row-based analytics service, a speedy, column-based analytics database is available for real-time analytics.

> [!TIP]
> Analytics SDKs
> 
> SDKs for [Enterprise Analytics](../../../enterprise-analytics/current/intro/intro.md) — Couchbase's analytical database for real time apps and operational intelligence (RT-OLAP) — are available for the Go, Java, Node.js, and Python platforms. See the [Enterprise Analytics SDK pages](../../../home/analytics-sdk.md) for more information.
> 
> Currently, different SDKs are needed to connect to [Capella Analytics](../../../analytics/intro/intro.md) — as this service does not have Enterprise Analytics' load balancer, and uses a different connection protocol. Capella Analytics SDKs (also known as Columnar SDKs) are available for the Go, Java, Node.js, and Python platforms. See the [Capella Analytics SDK pages](../../../home/columnar-sdk.md) for more information.
