What is @sentry/node?

The @sentry/node package is a tool designed for real-time monitoring and fixing crashes in Node.js applications. It provides error tracking and performance monitoring, helping developers to quickly identify, diagnose, and fix problems in their applications. Sentry integrates seamlessly with your existing codebase, offering a range of features to enhance application reliability and user experience.

What are @sentry/node's main functionalities?

Error Tracking

Automatically capture exceptions and errors in your Node.js applications. The code initializes Sentry with your project's DSN and demonstrates how an uncaught exception is automatically reported to Sentry.

const Sentry = require('@sentry/node');
Sentry.init({ dsn: 'YOUR_DSN_HERE' });

app.get('/', function mainHandler(req, res) {
  throw new Error('Broke!');
});

Performance Monitoring

Track the performance of your application, including request times and slow operations. This code sample starts a transaction, simulates an operation with a timeout, and then finishes the transaction, which is then reported to Sentry for performance analysis.

const Sentry = require('@sentry/node');
const transaction = Sentry.startTransaction({ op: 'test', name: 'My First Test Transaction' });

setTimeout(() => {
  transaction.finish();
}, 99);

Custom Event Capturing

Send custom messages or events to Sentry. This is useful for capturing non-exception events that are significant for your application's health monitoring and diagnostics.

const Sentry = require('@sentry/node');

Sentry.captureMessage('Something went wrong', 'error');
