I recently had to integrate Rollbar (a service to track errors) with a JS application. One nice thing about Rollbar is that if you provide it with source maps, it will point to you where the error is in the original unminified code.

Since the application is deployed with Ansible …

I recently integrated Rollbar (a service to Detect, diagnose and debug errors with ease) into an Aurelia application. I explain here how I did it. I start by explaining how logging works with Aurelia and then how I integrated Rollbar into this.
