The Pharos Of PWA, Deconstructing a Lighthouse Audit
summary
Lighthouse v3 runs automated audits in four categories—performance, PWA, accessibility, best practices—and ships 100+ audits with metrics like First Contentful Paint, Speed Index, Time to Interactive and estimated input latency. It runs from Chrome DevTools, CLI or WebPageTest, exports reports to a viewer, and now offers an API (apply for access) plus Chrome UX BigQuery data for real‑world comparison. Custom gatherers, audits and configs let teams do croned bulk analysis and Project Glass claims to cut variability by >50%.
