@datadog/browser-core

Telemetry Data Collection

This code initializes the Datadog RUM SDK, which relies on @datadog/browser-core to collect telemetry data such as performance metrics, errors, and user actions.

import { datadogRum } from '@datadog/browser-rum';
datadogRum.init({
  applicationId: 'YOUR_APP_ID',
  clientToken: 'YOUR_CLIENT_TOKEN',
  site: 'datadoghq.com',
  service:'your-service-name',
  // Specify a version number to identify the deployed version of your application in Datadog
  version: '1.0.0',
  sampleRate: 100,
  trackInteractions: true,
});

Error Tracking

This code snippet demonstrates how to initialize Datadog's logging library, which uses @datadog/browser-core to track and forward errors to Datadog's servers for monitoring and alerting.

import { datadogLogs } from '@datadog/browser-logs';
datadogLogs.init({
  clientToken: 'YOUR_CLIENT_TOKEN',
  site: 'datadoghq.com',
  forwardErrorsToLogs: true,
  sampleRate: 100
});
datadogLogs.logger.error('Error message', { error: new Error('Error stack') });

User Action Tracking

This code demonstrates how to manually track user actions such as clicks, which can be used to measure user interaction and engagement within the application.

import { datadogRum } from '@datadog/browser-rum';
datadogRum.startUserAction('click', 'button clicked', {
  element: document.getElementById('submit-button')
});
// After the action is completed
setTimeout(() => {
  datadogRum.stopUserAction();
}, 1000);
