By name: nextjs-review description: Reviews Next.js and TypeScript code for critical issues only - types, performance, security, and App Router patterns.
Next.js + TypeScript Review (Essentials Only)
Focus on issues that actually break things or cause real problems.
What to Check
1. TypeScript - Does it have types?
- Props missing types → Add interface
- Using
any→ Use proper type - Function missing return type → Add it
- API response not typed → Create interface
2. Next.js Patterns - Is it using the right pattern?
- Should it be Server or Client Component?
- Using next/image instead of
?
- Has loading.tsx and error.tsx?
- Metadata for SEO?
3. Performance - Will it be slow?
- Fetching data in a loop? (N+1 problem)
- Missing cache settings?
- Heavy component not code-split?
- No debouncing on search/input?
4. Security - Can it be exploited?
- Secrets exposed in client code?
- No authentication on API routes?
- SQL injection possible?
- No input validation?
