Srbhr Resume Matcher Nextjs Performance

Next.js Performance

Before Writing Code

1. Read docs/agent/architecture/nextjs-critical-fixes.md for full patterns
2. Check existing components in apps/frontend/components/

Critical Rules

Waterfalls

• Use Promise.all() for independent fetches
• Wrap slow data in <Suspense> boundaries
• Defer await into branches where needed

// WRONG
const resumes = await fetchResumes();
const jobs = await fetchJobs();

// RIGHT
const [resumes, jobs] = await Promise.all([fetchResumes(), fetchJobs()]);

Bundle Size

• NO barrel imports: import X from 'lucide-react' is WRONG
• YES direct imports: import X from 'lucide-react/dist/esm/icons/x'
• Use next/dynamic for heavy components (editors, charts, PDF)
• Defer analytics with ssr: false

import dynamic from 'next/dynamic';
const HeavyEditor = dynamic(() => import('./HeavyEditor'), { ssr: false });

Server Actions

• ALWAYS check auth INSIDE the action, not just middleware
• Verify resource ownership before mutations

Production Build

• Run npm run build && npm run start, NOT npm run dev
• Docker must use standalone output

Pre-PR Checklist

[ ] No sequential awaits for independent data
[ ] Icons imported directly (not barrel)
[ ] Heavy components use next/dynamic
[ ] Server Actions have auth inside
[ ] Suspense around slow fetches
