The healthchecks-io-client library contains two simple and convenient HTTP clients for making requests to the Healthchecks.io Ping API and the Healthchecks.io Management API.

Using NPM:

$ npm install healthchecks-io-client

Using Yarn:

$ yarn add healthchecks-io-client

The library exports two classes for interacting with the Healthchecks.io APIs and a ping shorthand/wrapper function. The HealthChecksPingClient class interacts with the Healthchecks.io Ping API. The HealthChecksApiClient class interacts with the Healthchecks.io Management API.

For a HealthChecksPingClient instance, you'll need the uuid of a health check. For a HealthChecksApiClient instance, you'll need an API key provided by Healthchecks.io. You can provide the API key as an apiKey option or set the API key as an environment variable using HC_API_KEY. By default, the client will use the HC_API_KEY environment variable if the apiKey option is not provided.

const {
  HealthChecksPingClient,
  HealthChecksApiClient
} = require('healthchecks-io-client');

// Creating a ping API client.
const pingClient = new HealthChecksPingClient({
  uuid: 'HEALTH-CHECKS-UUID'
});

// Creating a management API client.
const apiClient = new HealthChecksApiClient({
  apiKey: 'HEALTH-CHECKS-API-KEY'
});

import {
  HealthChecksPingClient,
  HealthChecksApiClient
} from 'healthchecks-io-client';

// Creating a ping API client.
const pingClient = new HealthChecksPingClient({
  uuid: 'HEALTH-CHECKS-UUID'
});

// Creating a management API client.
const apiClient = new HealthChecksApiClient({
  apiKey: 'HEALTH-CHECKS-API-KEY'
});

For a HealthChecksApiClient instance, it is required to set the API key parameter as either an environment variable or as an option when instantiating the client. An API key is necessary to execute HealthChecksApiClient calls. If an API key is not provided or cannot be determined, then an error is thrown.

const { HealthChecksApiClient } = require('healthchecks-io-client');

// Set the API key as an environment variable.
process.env.HC_API_KEY = 'HEALTH-CHECKS-API-KEY';

const apiClient = new HealthChecksApiClient();

Linux:

$ HC_API_KEY=HEALTH-CHECKS-API-KEY node app.js

Windows:

> cmd /C "set HC_API_KEY=HEALTH-CHECKS-API-KEY && node app.js"

These are the available options for creating a HealthChecksPingClient instance.

These are the available options for creating a HealthChecksApiClient instance.

Create an instance:

const { HealthChecksPingClient } = require('healthchecks-io-client');

// Creating a ping API client.
const pingClient = new HealthChecksPingClient({
  uuid: 'HEALTH-CHECKS-UUID'
});

Send a "success" ping:

async function performTask() {
  /*
   * Add task logic here.
   */

  // Signal a "success" after completion.
  await pingClient.success();
}

Send a "success" ping on task completion and send a "fail" ping on task failure:

async function performTask() {
  try {
    /*
     * Add task logic here.
     */

    // Signal a "success" after completion.
    await pingClient.success();
  } catch(err) {
    // Send a "fail" ping on failure.
    await pingClient.fail();
  }
}

Alternatively, instead of exporting the HealthChecksPingClient you can export just the ping functionality.

// Export the 'ping' function.
const { ping } = require('healthchecks-io-client');

Send a "success" ping:

async function performTask(uuid) {
  /*
   * Add task logic here.
   */

  // Signal a "success" after completion.
  await ping(uuid, 'success');
}

Send a "success" ping on task completion and send a "fail" ping on task failure:

async function performTask(uuid) {
  try {
    /*
     * Add task logic here.
     */

    // Signal a "success" after completion.
    await ping(uuid);
  } catch(err) {
    // Send a "fail" ping on failure.
    await ping(uuid, 'fail');
  }
}

Create an instance:

const { HealthChecksApiClient } = require('healthchecks-io-client');

// Creating a management API client.
const apiClient = new HealthChecksApiClient({
  apiKey: 'HEALTH-CHECKS-API-KEY'
});

Get a list of health checks:

async function getHealthChecks() {
  try {
    return await apiClient.getChecks();
  } catch(err) {
    console.error(err);
  }
}

Get a certain health check:

async function getHealthCheck(uuid) {
  try {
    return await apiClient.getCheck(uuid);
  } catch(err) {
    console.error(err);
  }
}

Create a new health check:

async function createHealthCheck() {
  try {
    return await apiClient.createCheck({
      name: 'App Check',
      tags: 'prod app',
    });
  } catch(err) {
    console.error(err);
  }
}
