rollbar

What is rollbar?

Rollbar is a real-time error tracking and monitoring tool for JavaScript applications. It helps developers to detect, diagnose, and fix errors in their applications by providing detailed error reports and notifications.

What are rollbar's main functionalities?

Error Tracking

Rollbar can automatically capture and report uncaught exceptions and unhandled promise rejections. This helps in tracking errors that occur in the application.

const Rollbar = require('rollbar');
const rollbar = new Rollbar({
  accessToken: 'YOUR_ACCESS_TOKEN',
  captureUncaught: true,
  captureUnhandledRejections: true
});

// Example of tracking an error
try {
  throw new Error('Test error');
} catch (e) {
  rollbar.error(e);
}

Custom Logging

Rollbar allows custom logging of messages, warnings, and info messages. This can be useful for tracking specific events or conditions in the application.

const Rollbar = require('rollbar');
const rollbar = new Rollbar({
  accessToken: 'YOUR_ACCESS_TOKEN'
});

// Log a custom message
rollbar.log('Custom log message');

// Log a warning
rollbar.warning('This is a warning');

// Log an info message
rollbar.info('This is an info message');

Telemetry

Rollbar can capture telemetry data such as console logs, network requests, and DOM events. This helps in understanding the context in which an error occurred.

const Rollbar = require('rollbar');
const rollbar = new Rollbar({
  accessToken: 'YOUR_ACCESS_TOKEN',
  captureUncaught: true,
  captureUnhandledRejections: true,
  autoInstrument: true
});

// Example of adding custom telemetry data
rollbar.configure({
  payload: {
    telemetry: [
      { type: 'log', level: 'info', body: 'Custom telemetry data' }
    ]
  }
});
