Community Session: Web Performance

In this Vercel Community Livestream, Dom Sipowicz, a Senior Solutions Engineer at Vercel, discusses web performance with hosts Anshuman and Jacob, focusing on common mistakes enterprises make, particularly over-fixating on Lighthouse scores instead of Core Web Vitals (LCP, INP, CLS). Dom shares anti-patterns noticed during code review audits, such as not using ISR, improper experimentation implementation leading to CLS, and using JavaScript for media queries. He also highlights the importance of Vercel Speed Insights for debugging and offers tips for optimizing web performance, including using Vercel data cache and strategically using regions to minimize latency. The conversation also touches on micro frontends and how AI tools can aid in debugging performance issues.
