Getting Started with Airbrake:

Airbrake simplifies error monitoring implementation. After creating a free 14-day trial account (no credit card required), you'll receive pre-written integration code for various languages. Simply add your project ID and API key to your application.

Monitoring an Express.js App (Example):

Let's illustrate integration with a Node.js Express.js application. Assuming you have Node.js and npm (or yarn) installed:

1. Create an Express app:

   express sample-app
   cd sample-app
   npm install  // or yarn

2. Add Airbrake to dependencies: In package.json, add airbrake to the dependencies:

   {
     // ... existing dependencies ...
     "airbrake": "^2.1.0" // Or latest version
   }

   Then run npm install (or yarn) again.

3. Integrate Airbrake: In app.js, add the following code after defining the app variable:

   var airbrake = require('airbrake').createClient(
     '<your_airbrake_project_id>',
     '<your_airbrake_api_key>'
   );
   app.use(airbrake.expressHandler());

   Replace placeholders with your Airbrake project ID and API key.

4. Trigger an error (for testing): In routes/index.js, add code to simulate an error:

   router.get('/', function(req, res, next) {
     res.render('index', { title: 'Express' });
     throw new Error('Test Error');
   });

5. View error reports: Airbrake will notify you via email (or your configured alert method) and display the error details in your dashboard, including backtraces and environment information. (See accompanying images for examples of Airbrake's reporting interface).

Conclusion:

Airbrake empowers developers to proactively identify and resolve errors, saving valuable time and resources. Its detailed reporting and seamless integration make it an invaluable tool for improving application reliability and user experience.
