Can all browser console messages and errors be sent to a different machine using a pipeline?

Currently, I am in the process of troubleshooting a javascript error that is occurring within a Cordova app's InAppBrowser on an Android device. Despite being able to connect to the web-view on the phone using Chrome's remote debugging tools, the console output is strangely empty, which is not expected as there are supposed to be miscellaneous messages and warnings appearing regardless of the error being triggered or not.

After exhausting all my options to retrieve the console and error messages, I am at a dead end. Is there a possibility of instructing the webview/javascript to send all error messages to a remote location? (Of course, I would never deploy an application with such a setup.)

Answer №1

One way to handle JavaScript errors is by utilizing window.onerror to catch them. The concept is to capture the error and then send it to a logging server for tracking.

window.onerror = function (msg, url, lineNo, columnNo, error) {
  alert(msg)
  // Log error to external server.
  // axios.post(url, JSON.stringify({msg, url, lineNo, columnNo, error}))
}

const test = undefined

test.error

This practice is implemented in my live environments, aiding in the quick identification and resolution of issues.

Answer №2

If you're interested in sending error logs and other information to a different device, you can utilize the Reporting API. This API allows for the use of the Report-To server header (potentially in conjunction with other headers) to facilitate the reporting of specified errors to a designated endpoint. Check out a selection of available report types (further information on Network Error Logging). This feature is currently supported in Chrome/Edge, and can be activated via about:config in Firefox.
