InfluxDB 2.0 JavaScript client

influxdb-client-js

This repository contains the JavaScript client library for use with InfluxDB 2.x and Flux. This client supports Node.js, browser, and Deno environments. InfluxDB 3.x users should instead use the lightweight v3 client library. InfluxDB 1.x users may want to use the node-influx client library.

For ease of migration and a consistent query and write experience, v2 users should consider using InfluxQL and the node-influx client library.

Features

InfluxDB 2.x client consists of two main packages

• @influxdata/influxdb-client
  • Query data using the Flux language
  • Write data to InfluxDB
    • batch data in the background
    • retry automatically on failure
• @influxdata/influxdb-client-apis
  • Create/Modify/Delete/Manage
    • buckets
    • tasks
    • authorizations
    • sources
    • ... and other InfluxDB domain objects
  • Delete data from a bucket
  • Invoke a flux script
  • built on @influxdata/influxdb-client

Installation

To write or query InfluxDB, add @influxdata/influxdb-client as a dependency to your project using your favorite package manager.

$ npm install --save @influxdata/influxdb-client
$ yarn add @influxdata/influxdb-client
$ pnpm add @influxdata/influxdb-client

If you target Node.js, use @influxdata/influxdb-client. It provides main (CJS), module (ESM), and browser (UMD) exports.

If you target browsers (including Deno and Ionic), use @influxdata/influxdb-client-browser in place of @influxdata/influxdb-client. It provides main (UMD) and module (ESM) exports.

To use InfluxDB management APIs in your project, also add @influxdata/influxdb-client-apis as a dependency to your project.

$ npm install --save @influxdata/influxdb-client-apis
$ yarn add @influxdata/influxdb-client-apis
$ pnpm add @influxdata/influxdb-client-apis
