# Node.js JavaScript client library

#### Use InfluxDB 3 clients to query

InfluxDB 3 supports [compatibility endpoints for *writing data*](/influxdb3/enterprise/write-data/compatibility-apis/) using InfluxDB v2 and v1 tools. However, the `/api/v2/query` API endpoint and associated tooling, such as InfluxDB v2 client libraries and the `influx` CLI, *can’t query* data stored in InfluxDB 3 Enterprise.

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

[**Compare tools you can use**](/influxdb3/enterprise/get-started/#tools-to-use) to interact with InfluxDB 3 Enterprise.

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 3 Enterprise database.

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