• Understand how Vercel's image optimization actually works under the hood
• Large unprocessed originals from a CMS are the fastest way to waste money
• Overly aggressive deviceSizes and using next/image for tiny icons add cost with little benefit

A practical look at how to use Lighthouse for Next.js apps: what to pay attention to, what to ignore, and how to focus on real user experience instead of chasing perfect scores.

• Treat Lighthouse as a lab smoke test, not the ultimate judge of UX
• Focus on LCP, INP, and CLS rather than the raw 0-100 score
• Use Lighthouse to catch obvious issues, field data to set priorities

A hands-on cheat sheet for reducing LCP, INP, and CLS in real-world Next.js apps, focusing on images, JS bundles, backend calls, and layout patterns.

• Treat LCP as “when the main thing appears” and prioritize hero content accordingly
• Reduce INP by trimming client-side JS, lazy-loading heavy widgets, and avoiding long main-thread tasks
• Fix CLS by reserving space for images and dynamic blocks, and stabilizing fonts and layout
