JavaScript and InfluxDB

Build IoT, analytics, and cloud applications using the JavaScript client library with InfluxDB.

Why use the InfluxDB JavaScript Client Library?

InfluxDB is an API-first time series database for your JavaScript applications. Use the InfluxDB open-source JavaScript API client to write and query data in Node.js, browser, and Deno environments and even manage your InfluxDB instance from within your application.

Key features

• Provides API access to all InfluxDB Write and Read functionality, settings, and advanced features
• Write data in InfluxDB line protocol or point data structure
• Automatically retry requests on failure
• Batch data to InfluxDB to gain greater efficiency
• Return InfluxDB data as a Flux Table Structure, string, csv, stream, or dataframe
• Delete data from a particular bucket
• Invoke a Flux script
• Create and manage your environment (buckets, tasks, authorization, source)

Building IoT App with the JavaScript client library

const {InfluxDB, flux} = require('@influxdata/influxdb-client')

const bucket = 'my-bucket'

const client = new InfluxDB({url: url, token: token})

  |> range(start: -1d)
  |> filter(fn: (r) => r._measurement == "weatherstation")`
