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. Start a new Node.js project. The npm package manager is included with Node.js.

npm init -y influx-node-app

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. Create a TypeScript configuration with default values.

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

    tsc -w -p

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

    Replace the following:

    • YOUR_API_TOKEN: InfluxDB API token
    • YOUR_ORG: InfluxDB organization ID
    • YOUR_BUCKET: InfluxDB bucket name
  2. Run an example script.


For more examples and information, see the JavaScript client on GitHub.

The URL in the examples depends on your InfluxDB Cloud region.
