Install the InfluxDB JavaScript client library

Install Node.js

  1. Install Node.js.

  2. Ensure that InfluxDB is running and you can connect to it. For information about what URL to use to connect to InfluxDB OSS or InfluxDB Cloud, see InfluxDB URLs.

  3. Create a directory for your new Node.js project, and then change to the directory–for example, enter the following command into your terminal:

    mkdir influx-node-app && cd influx-node-app 
  4. Enter the following command to generate an npm package for your project.

    • npm: the package manager included with Node.js
    • -y: uses defaults for the package and bypasses prompts
    npm init -y

Install TypeScript

Many of the client library examples use TypeScript. Follow these steps to initialize the TypeScript project:

  1. Install TypeScript and type definitions for Node.js.

    npm i -g typescript && npm i --save-dev @types/node
  2. Enter the following command to create a TypeScript configuration (tsconfig.json) with default values:

    tsc --init
  3. Run the TypeScript compiler. To recompile your code automatically as you make changes, pass the --watch, -w flag to the compiler.

    tsc --watch

Install dependencies

The JavaScript client library contains two packages: @influxdata/influxdb-client and @influxdata/influxdb-client-apis. Add both as dependencies of your project.

  1. Open a new terminal window and install @influxdata/influxdb-client for querying and writing data:

    npm install --save @influxdata/influxdb-client
  2. Install @influxdata/influxdb-client-apis for access to the InfluxDB management APIs:

    npm install --save @influxdata/influxdb-client-apis

Next steps

Once you’ve installed the JavaScript client library, you’re ready to write data to InfluxDB or get started with other examples from the client library.

Get started with examples

The client examples include an env module for accessing your InfluxDB properties from environment variables or from env.mjs. The examples use these properties to interact with the InfluxDB API.

  1. Set environment variables or update env.mjs with your InfluxDB bucket, organization, token, and URL.

    export INFLUX_URL=http://localhost:8086
    export INFLUX_TOKEN=YOUR_API_TOKEN
    export INFLUX_ORG=YOUR_ORG
    export INFLUX_BUCKET=YOUR_BUCKET

    Replace the following:

    • YOUR_API_TOKEN: InfluxDB API token
    • YOUR_ORG: InfluxDB organization ID
    • YOUR_BUCKET: InfluxDB bucket name
  2. Run one of the influxdb-client-js example scripts.

    query.ts

New in InfluxDB 3.5

Key enhancements in InfluxDB 3.5 and the InfluxDB 3 Explorer 1.3.

See the Blog Post

InfluxDB 3.5 is now available for both Core and Enterprise, introducing custom plugin repository support, enhanced operational visibility with queryable CLI parameters and manual node management, stronger security controls, and general performance improvements.

InfluxDB 3 Explorer 1.3 brings powerful new capabilities including Dashboards (beta) for saving and organizing your favorite queries, and cache querying for instant access to Last Value and Distinct Value caches—making Explorer a more comprehensive workspace for time series monitoring and analysis.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
