@sentry/node
Advanced tools
Package description
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.
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');Bugsnag provides error monitoring for web, mobile, and server applications. Similar to @sentry/node, it offers real-time error reporting and allows for detailed error diagnostics and performance monitoring. Bugsnag differentiates itself with features tailored to mobile app monitoring.
Rollbar offers real-time error tracking and debugging tools for developers. Like @sentry/node, it supports multiple programming languages and frameworks, including Node.js. Rollbar emphasizes its ability to help teams with workflow integrations and automated error grouping for efficient management.
Raygun provides crash reporting, real-user monitoring, and deployment tracking. It's similar to @sentry/node in its core functionalities of error tracking and performance monitoring but also offers unique features like user journey tracking and version comparisons to understand the impact of deployments.
Changelog
8.0.0-beta.2
propagationContext on spanEnd to keep trace consistentTo ensure consistency throughout a route's duration, we update the scope's propagation context when the initial page load or navigation span ends. This keeps span-specific attributes like the sampled decision and dynamic sampling context on the scope, even after the transaction has ended.
We won't assume window.dodument is available in the browser SDKs anymore. This should prevent errors in environments
where window.document is not available (such as web workers).

Note that it is necessary to initialize Sentry before you import any package that may be instrumented by us.

Due to the way OpenTelemetry handles instrumentation, this only works out of the box for CommonJS (require)
applications.
There is experimental support for running OpenTelemetry with ESM ("type": "module"):
node --experimental-loader=@opentelemetry/instrumentation/hook.mjs ./app.js
You'll need to install @opentelemetry/instrumentation in your app to ensure this works.
See OpenTelemetry Instrumentation Docs for details on this - but note that this is a) experimental, and b) does not work with all integrations.
