@bugsnag/core

What is @bugsnag/core?

@bugsnag/core is a core library for the Bugsnag error monitoring service. It provides the essential functionality for capturing and reporting errors in your applications. This package is typically used as a dependency for other Bugsnag notifier packages that are specific to different platforms (e.g., JavaScript, React Native, etc.).

What are @bugsnag/core's main functionalities?

Initializing Bugsnag

This code initializes the Bugsnag client with your API key, allowing you to start capturing and reporting errors.

const Bugsnag = require('@bugsnag/core');
const bugsnagClient = Bugsnag.createClient({ apiKey: 'YOUR_API_KEY' });

Notifying Errors

This code sends a notification to Bugsnag about an error. This is useful for capturing and reporting errors that occur in your application.

bugsnagClient.notify(new Error('Test error'));

Adding Metadata

This code adds custom metadata to the error report, which can be useful for providing additional context about the error.

bugsnagClient.notify(new Error('Test error'), event => {
  event.addMetadata('account', {
    id: 123,
    name: 'Acme Co'
  });
});

Breadcrumbs

This code leaves a breadcrumb, which is a log of actions that happened before an error occurred. Breadcrumbs help in understanding the sequence of events leading up to an error.

bugsnagClient.leaveBreadcrumb('User clicked button', { buttonName: 'Submit' });

README

@bugsnag/core

This package contains the core classes and utilities common to the Bugsnag notifier for any JS-based platform:

• Client class
• Report class
• Breadcrumb class
• Session class
• config scheme and utils
• Basic JS polyfills that don't pollute the global scope (for support back to IE8)
• and a couple of other small utilities

Unless you are writing your own notifier, it is unlikely that you want to install this module – for the universal error reporting client, see @bugsnag/js.
