🏗️ 架构原则
✅ 正确做法
// 1. 使用通用能力,不要重复造轮子
import { createStreamingService } from '../../../common/streaming';
// 2. 遵循云原生规范
await storage.upload(); // 不要用 fs.writeFileSync()
// 3. 使用结构化日志
logger.info('[Module] 操作', { detail }); // 不要用 console.log()
// 4. 统一认证
fastify.get('/api', { preHandler: [authenticate] });
// 5. 标准化API格式
// OpenAI Compatible, not 自定义格式
❌ 错误做法
// 1. 自己实现已有的能力
reply.raw.write('data: ...'); // ❌ 应该用 StreamingService
// 2. 直接操作本地文件
fs.writeFileSync('/tmp/file'); // ❌ 应该用 storage
// 3. 使用 console.log
console.log('debug'); // ❌ 应该用 logger
// 4. 硬编码用户ID
const userId = 'test'; // ❌ 应该用 getUserId(request)
// 5. 自定义格式
{ type: 'delta', content: 'xxx' } // ❌ 应该用 OpenAI Compatible
