TypeScript Rules

Strict Requirements

• Strict Mode — all strict checks enforced
• ZERO any types — use proper types or unknown + narrowing
• ZERO console.log — NestJS Logger (backend); remove before commit (frontend)

Comment Language Policy

• Comments: Thai (เข้าใจง่ายสำหรับทีมไทย)
• Code Identifiers: English (variables, functions, classes)

Error Handling Pattern

// Backend (NestJS)
import { Logger } from '@nestjs/common';
const logger = new Logger('ServiceName');

// Use logger instead of console.log
logger.error('Error message', error.stack);
throw new HttpException('Message', HttpStatus.BAD_REQUEST);

// Frontend (Next.js)
// Remove all console.log before commit
// Use proper error boundaries and toast notifications
