Express Error & Performance Monitoring

Using Airbrake with Express.js

This example Node.js application uses Express.js and sets up Airbrake to report errors and performance data. To adapt this example to your app, follow these steps:

  1. Install the package:

npm install @airbrake/node

  1. Includethe required Airbrake libraries in your  app.js :

const Airbrake = require('@airbrake/node');
const airbrakeExpress = require('@airbrake/node/dist/instrumentation/express');

  1. ConfigureAirbrake with your project's credentials:

const airbrake = new Airbrake.Notifier({
 projectId: process.env.AIRBRAKE_PROJECT_ID,
 projectKey: process.env.AIRBRAKE_PROJECT_KEY,

  1. This middleware should be added before any routes are defined:


  1. The error handler middleware should be defined last. For more info on how thisworks, see the official Express error handling doc.


  1. The last step is to run your app. To test that you've configured Air brake correctly, you can throw an error inside any of your routes:

app.get('/hello/:name', function hello(_req, _res) {
 throw new Error('Hello from Airbrake!');

Any unhandled errors that are thrown will now be reported to Airbrake. See the basic usage to learn how to manually send errors to Airbrake.

Note: To see this all in action, take a look at our example app.js file and to run the example, follow the next steps.

Running the example app

If you want to run this example application locally, follow these steps:

  1. Clone the airbrake-js repo:

git clone

  1. Navigate to this directory:

cd airbrake-js/packages/node/examples/express

  1. Run the following commands while providing your `project ID` and `project API key`

npm install
node app.js
firefox localhost:3000

Frictionless error monitoring for Express

You monitor your servers and your apps, but is anyone monitoring your user experience? Every minute that your customer experience is compromised costs you more than just money. It costs you goodwill. Airbrake Express Error Monitoring can help.

Capturing Express errors is easy with the Airbrake Express Error Monitoring and Debugging tool. Airbrake installs in minutes and monitors your Express applications 24 hours/day, 7 days/week, notifying you in real-time of new errors occurrences. Detailed stack traces, environment, and user reports make Express error handling simple. With Airbrake, there's no need to sift through massive log reports for that elusive error. Instead, you’ll receive instant insight into the line of code that broke, the environment in which it occurred, and the deployment it's tied to.

Airbrake makes drilling down and understanding what's happening with your Express app easy. You can quickly fix error issues using:
