In war, no plan survives contact with the enemy. In tech, no code survives contact with real users. In this episode, I discuss systems to monitor and stay alerted about errors in production. By watching me debug a few of my exceptions, you'll learn: 1) How these tools can integrate back-traces of the original source code, rather than any minified or transpiled versions. 2) How to configure your error reporting to include not just back-end, but also errors in the front-end and background queues. 3) How these tools can speed up back-end debugging by showing the SQL queries prior to the error 4) How these tools speed up front-end debugging by using telemetry to list the browser events leading up the error. 5) How you can use the data persisted in the error tracking tool to salvage mission-critical data you would otherwise have lost.
