How do I use Sentry for error tracking in my Node.js application?

To use Sentry for error tracking in Node.js, first, install the Sentry SDK using npm. You can do this by running npm install @sentry/node.

What do I do after installing the SDK?

After installation, you need to initialize Sentry in your application. You can do this by adding the following code at the top of your main file:

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

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN',
});

How can I capture errors with Sentry?

You can capture errors by using Sentry.captureException(error) in your error handling code. For example:

app.use((err, req, res, next) => {
  Sentry.captureException(err);
  res.status(500).send('Something went wrong!');
});

Is there a way to track performance as well?

Yes, Sentry also provides performance monitoring. You can enable it by adding tracesSampleRate in the initialization options. For example:

Sentry.init({
  dsn: 'YOUR_SENTRY_DSN',
  tracesSampleRate: 1.0, // Adjust this value as needed
});
