# Node.js JavaScript client library

### Use InfluxDB 3 clients

The `/api/v2/query` API endpoint and associated tooling, such as InfluxDB v2 client libraries and the `influx` CLI, **can’t** query an InfluxDB cluster.

[InfluxDB 3 client libraries](/influxdb3/clustered/client-libraries/v3/) are available that integrate with your code to write and query data stored in InfluxDB Clustered.

InfluxDB 3 supports many different tools for [**writing**](/influxdb3/clustered/write-data/) and [**querying**](/influxdb3/clustered/query-data/) data. [**Compare tools you can use**](/influxdb3/clustered/get-started/#tools-to-use) to interact with InfluxDB Clustered.

The [InfluxDB v2 JavaScript client library](https://github.com/influxdata/influxdb-client-js) integrates with the InfluxDB v2 API to write data from Node.js and browser applications to an InfluxDB Clustered database.

## Use the client library in a Node.js application
