A practical security checklist every modern web application must satisfy before deployment: runtime input validation, rate limiting, secure HTTP-only cookies, and edge firewall rules.
01Runtime Validation with Zod
Never trust incoming client payloads. TypeScript types are stripped at compile time, leaving pure JavaScript at runtime. Enforcing Zod validation schemas on every route handler prevents malformed inputs from reaching database drivers.
Architectural Takeaways:
- 100% strict schema sanitization on all POST/PUT/PATCH routes.
- Automatic rejection of unescaped injection strings.
- Type inference guarantees complete TypeScript safety across the codebase.
