@sentry/core

What is @sentry/core?

The @sentry/core package is part of the Sentry SDK for JavaScript, which is designed for real-time monitoring and tracking of application health, errors, and performance issues. It provides the core functionalities needed for initializing and configuring Sentry in your application, handling exceptions, and capturing messages and events.

What are @sentry/core's main functionalities?

Initialization and Configuration

This feature allows you to initialize Sentry in your application with your project's DSN (Data Source Name). It is the first step in integrating Sentry into your project for error tracking and performance monitoring.

Sentry.init({ dsn: 'YOUR_DSN_HERE' });

Capturing Exceptions

This feature enables you to capture exceptions in your code and send them to Sentry for monitoring and analysis. It helps in identifying and debugging errors in your application.

try { myFunction(); } catch (e) { Sentry.captureException(e); }

Capturing Messages

This feature allows you to capture custom messages or log messages in Sentry. It can be used for tracking custom events or information that is not necessarily an error.

Sentry.captureMessage('Something went wrong');

Other packages similar to @sentry/core

logrocket

LogRocket is a frontend application monitoring and product analytics tool that provides session replay, performance monitoring, and error tracking. It offers a more visual approach to debugging by allowing you to replay problems as if you were in your user's shoes. Compared to @sentry/core, LogRocket focuses more on the user experience aspect alongside error tracking.

bugsnag

Bugsnag provides error monitoring and application stability management. It offers features for capturing and tracking errors, diagnosing issues, and improving app stability. Bugsnag is similar to @sentry/core in its core functionalities of error tracking and reporting but also emphasizes application stability metrics and trends.

Important Changes

• feat: Add Supabase Integration (#15719)

This PR adds Supabase integration to @sentry/core, allowing automatic instrumentation of Supabase client operations (database queries and authentication) for performance monitoring and error tracking.

• feat(nestjs): Gracefully handle RPC scenarios in SentryGlobalFilter (#16066)

This PR adds better RPC exception handling to @sentry/nestjs, preventing application crashes while still capturing errors and warning users when a dedicated filter is needed. The implementation gracefully handles the 'rpc' context type in SentryGlobalFilter to improve reliability in hybrid applications.

• feat(react-router): Trace propagation (#16070)

This PR adds trace propagation to @sentry/react-router by providing utilities to inject trace meta tags into HTML headers and offering a pre-built Sentry-instrumented request handler, improving distributed tracing capabilities across page loads.

Other Changes

• feat(deps): Bump @prisma/instrumentation from 6.5.0 to 6.6.0 (#16102)
• feat(nextjs): Improve server component data (#15996)
• feat(nuxt): Log when adding HTML trace meta tags (#16044)
• fix(node): Make body capturing more robust (#16105)
• ref(node): Log when incoming request bodies are being captured (#16104)
