Legend has it that the lighthouse at Pharos helped ships avoid rocks that would wreck them, instead guiding them safely to port. Today, Project Lighthouse serves that purpose for modern progressive web apps by not only shedding a light on potential rocks that wreck app performance -- but also providing audit guidance that allows developers to navigate their way towards the safe harbor of PWA compliance.

We've all heard of Lighthouse audit scores. Chances are we've run the audit report, then blindly followed the guidance to get ourselves to that perfect 100. But have you ever wondered how it works? And why the issues revealed by the audit are important? And what the guidance provided actually achieves?

Come join me as we set sail into the Project Lighthouse documentation. We'll learn how to run a Lighthouse audit on a selected website, and use some of the guidance to changes that improve our audit scores. The bulk of the talk will then drill down into the features that Lighthouse evaluates for Performance, PWA compliance, Accessibility, SEO & more. At the end of the talk, we'll walk away with a better sense of the metrics, goals & best practices involved in crafting modern performant & progressive web apps.
