sdcorejs-review-performance-nextjs

What problem does it solve?

Detects Next.js landing-site performance regressions early by comparing real Lighthouse mobile metrics and bundle/cache/image/font/server signals against defined budgets.

Core Features & Use Cases

• Lighthouse mobile performance audit: Runs mobile preset to surface numeric Critical/Important findings (Performance, LCP, CLS, TBT, TTFB) per page.
• Bundle-size and chunk budget checks: Uses next/bundle-analyzer plus chunk scanning to flag oversized initial or lazy route payloads.
• Image, font, and ISR/cache strategy validation: Verifies image optimization patterns, font configuration (e.g., vietnamese subsets, swap), and "use cache" + cacheLife() on page.tsx.
• Third-party script weight review: Flags blocking/synchronous external scripts and encourages next/script strategy usage.
• Output as actionable audit report: Produces a structured report with Critical/Important/Minor findings tied to probes and expected thresholds for faster fixes.

Quick Start

Run the performance audit on your deployed or locally started Next.js staging site for the routes /vi, /vi/san-pham, and /vi/lien-he using your existing production build.
