Advanced tools
Package description
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.
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');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 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.
Changelog
7.110.0
You can now use a interactionsSampleRate to control the sample rate of INP spans. interactionsSampleRate is applied
on top of the global tracesSampleRate. Therefore if interactionsSampleRate is 0.5 and tracesSampleRate is 0.1,
then the actual sample rate for interactions is 0.05.
Sentry.init({
tracesSampleRate: 0.1,
integrations: [
Sentry.browserTracingIntegration({
interactionsSampleRate: 0.5,
}),
],
});
This release deprecates the Hub class, as well as the addRequestDataToTransaction method. The trpcMiddleware
