As there is no software without bugs, we must always assume there are bugs in our software. Subsequently, it would be very nice if we would be aware of those bugs as well. We cannot always be aware of all the bugs in our software, but we can be aware of all exceptions that occur in our software, using logging and telemetrics services. One of those services is Azure’s Application Insights which, among doing many other things, can collect browser exceptions coming from Javascript-based single page applications and provide much useful information about them.
