The Operable Front End

About this presentation

Operations engineers sometimes use the term "operability" when they talk about the ingredients for fast, stable, maintainable applications. While operability is usually discussed in the context of back-end systems, there's no reason instrumentation and observability should stop at the app server. This talk will take a broad look at what operability can mean in the context of the browser, and it'll lay out the metrics and tools that are needed to have operable front end code. We'll also look at some production situations where good client-side instrumentation uncovered an unexpected facet of performance, security, or user behavior. Finally, we'll dig into how to employ all of these metrics and techniques in service of a faster, more responsive end user experience.
