## Write data to InfluxDB with JavaScript ## Write data to InfluxDB with JavaScript
Use the Javascript library to write data to InfluxDB. Use the Javascript library to write data to InfluxDB in a Node.js environment.
1. Use the `getWriteApi` method of the InfluxDB client to create a **write client**. Provide your InfluxDB `org` and `bucket`. 1. Instantiate an `InfluxDB` client. Provide your InfluxDB `url` and `token`.
2. Use the `getWriteApi` method of the instantiated InfluxDB client to create a **write client**. Provide your InfluxDB `org` and `bucket`.
```js ```js
const writeApi = InfluxDB.getWriteApi(org, bucket) import {InfluxDB, Point} from '@influxdata/influxdb-client'
const influxDB = new InfluxDB({url, token})
const writeApi = influxDB.getWriteApi(org, bucket)
``` ```
The `useDefaultTags` method instructs the write api to use default tags when writing points. Create a [point](/influxdb/v2.0/reference/glossary/#point) and write it to InfluxDB using the `writePoint` method. The `tag` and `floatField` methods add key value pairs for the tags and fields, respectively. Close the client to flush all pending writes and finish.
