@datadog/browser-core

What is @datadog/browser-core?

The @datadog/browser-core package is a core library for Datadog's Real User Monitoring (RUM) and logging libraries. It provides foundational functionality for monitoring web applications, including the collection of telemetry data, handling of browser events, and communication with Datadog's servers.

What are @datadog/browser-core's main functionalities?

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);
