The raven-js npm package is a JavaScript client for Sentry, a real-time error tracking system. It allows developers to capture and report errors in their web applications, providing detailed context and stack traces to help diagnose and fix issues quickly.
Error Reporting
This feature allows you to capture and report exceptions to Sentry. By configuring Raven with your Sentry DSN and using the captureException method, you can send error details to Sentry for further analysis.
Raven.config('your-dsn').install();
try {
// Code that may throw an error
} catch (e) {
Raven.captureException(e);
}Breadcrumbs
Breadcrumbs are a way to record events that lead up to an error. This feature helps in understanding the sequence of actions that caused the error, making it easier to reproduce and fix.
Raven.config('your-dsn').install();
Raven.captureBreadcrumb({
message: 'User clicked on button',
category: 'ui',
level: 'info'
});Context
This feature allows you to add additional context to your error reports, such as user information and extra data. This can be very useful for debugging and understanding the environment in which the error occurred.
Raven.config('your-dsn').install();
Raven.setUserContext({
email: 'user@example.com',
id: '12345'
});
Raven.setExtraContext({
debug: true
});Bugsnag is another error monitoring tool that provides similar functionalities to Sentry. It allows you to capture and report errors, add breadcrumbs, and include additional context. Bugsnag also offers features like release tracking and user feedback collection.
