What are raven-js's main functionalities?
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
});
