isomorphic-influx

A library for writing stats to InfluxDB 2.0. Metrics can fire from either a Node server backend or from a browser.

Key concepts

Be sure to review the key concepts from the Influx documentation (fields, tags). Be aware that this library only supports InfluxDB 2.0 metrics, and not InfluxDB 1.0.

Usage

import { writeMetric } from "isomorphic-influx";

writeMetric(
  metricName, // Name of the metric you are logging
  (fieldSet = {}), // Fields to log, as an object
  (tagSet = {}), // Tag metadata to log, as an object
  (INFLUXDB_ORG_ID = process.env.INFLUXDB_ORG_ID), // InfluxDB Org ID
  (INFLUXDB_BUCKET_ID = process.env.INFLUXDB_BUCKET_ID), // InfluxDB Bucket ID
  (INFLUXDB_SERVER_URL = process.env.INFLUXDB_SERVER_URL), // InfluxDB server base URL
  (INFLUXDB_TOKEN = process.env.INFLUXDB_TOKEN) // InfluxDB account token
);

Under the hood, writeMetric is simply a fetch request, so you can chain a then handler for the success case, or a catch handler for request errors.

writeMetric(
  "temperature_updates",
  {
    temperature: 72.0,
    humidity: 50.0,
    isFanOn: true
  },
  {
    device_id: "raspberry-pi"
  }
)
  .then(() => {
    // Handle success
    console.log("Success!");
  })
  .catch(err => {
    // Handle errors
    console.error("Error updating metric", err);
  });
