@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(angular): Support Angular 19 (#14398)

  The @sentry/angular SDK can now be used with Angular 19. If you're upgrading to the new Angular version, you might want to migrate from the now deprecated APP_INITIALIZER token to provideAppInitializer. In this case, change the Sentry TraceService initialization in app.config.ts:

  // Angular 18
  export const appConfig: ApplicationConfig = {
    providers: [
      // other providers
      {
        provide: TraceService,
        deps: [Router],
      },
      {
        provide: APP_INITIALIZER,
        useFactory: () => () => {},
        deps: [TraceService],
        multi: true,
      },
    ],
  };
  
  // Angular 19
  export const appConfig: ApplicationConfig = {
    providers: [
      // other providers
      {
        provide: TraceService,
        deps: [Router],
      },
      provideAppInitializer(() => {
        inject(TraceService);
      }),
    ],
  };
  

• feat(core): Deprecate debugIntegration and sessionTimingIntegration (#14363)

  The debugIntegration was deprecated and will be removed in the next major version of the SDK. To log outgoing events, use Hook Options (beforeSend, beforeSendTransaction, ...).

  The sessionTimingIntegration was deprecated and will be removed in the next major version of the SDK. To capture session durations alongside events, use Context (Sentry.setContext()).

• feat(nestjs): Deprecate @WithSentry in favor of @SentryExceptionCaptured (#14323)

  The @WithSentry decorator was deprecated. Use @SentryExceptionCaptured instead. This is a simple renaming and functionality stays identical.

• feat(nestjs): Deprecate SentryTracingInterceptor, SentryService, SentryGlobalGenericFilter, SentryGlobalGraphQLFilter (#14371)

  The SentryTracingInterceptor was deprecated. If you are using @sentry/nestjs you can safely remove any references to the SentryTracingInterceptor. If you are using another package migrate to @sentry/nestjs and remove the SentryTracingInterceptor afterwards.

  The SentryService was deprecated and its functionality was added to Sentry.init. If you are using @sentry/nestjs you can safely remove any references to the SentryService. If you are using another package migrate to @sentry/nestjs and remove the SentryService afterwards.

  The SentryGlobalGenericFilter was deprecated. Use the SentryGlobalFilter instead which is a drop-in replacement.

  The SentryGlobalGraphQLFilter was deprecated. Use the SentryGlobalFilter instead which is a drop-in replacement.

• feat(node): Deprecate nestIntegration and setupNestErrorHandler in favor of using @sentry/nestjs (#14374)

  The nestIntegration and setupNestErrorHandler functions from @sentry/node were deprecated and will be removed in the next major version of the SDK. If you're using @sentry/node in a NestJS application, we recommend switching to our new dedicated @sentry/nestjs package.
