# Presence Service 架构文档
## 1. 概述
Presence Service 是一个基于 **DDD (领域驱动设计)** + **六边形架构 (Hexagonal Architecture)** + **CQRS** 模式构建的微服务，负责用户在线状态检测和活跃度分析。
### 1.1 核心职责
- **实时在线状态检测**: 基于心跳机制检测用户在线状态
- **日活统计 (DAU)**: 按日统计活跃用户数，支持地域维度
- **在线人数快照**: 定期记录在线人数历史
- **事件日志收集**: 收集客户端上报的分析事件
### 1.2 技术栈
| 组件 | 技术选型 |
|-----|---------|
| 运行时 | Node.js 20+ |
| 框架 | NestJS 10.x |
| ORM | Prisma 5.x |
| 数据库 | PostgreSQL 15 |
| 缓存 | Redis 7 |
| 消息队列 | Kafka |
| 语言 | TypeScript 5.x |
---
## 2. 架构模式
### 2.1 六边形架构 (Ports and Adapters)

```
### 2.2 CQRS 模式
服务采用 CQRS (Command Query Responsibility Segregation) 模式分离读写操作：
#### Commands (写操作)
- `RecordHeartbeatCommand` - 记录用户心跳
- `BatchEventsCommand` - 批量写入事件日志
- `SnapshotOnlineCountCommand` - 快照在线人数
- `CalculateDauCommand` - 计算日活统计
#### Queries (读操作)
- `GetOnlineCountQuery` - 查询当前在线人数
- `GetOnlineHistoryQuery` - 查询在线人数历史
- `GetDauQuery` - 查询日活统计

export const EVENT_LOG_REPOSITORY = Symbol('EVENT_LOG_REPOSITORY');
export interface IEventLogRepository {
batchInsert(logs: EventLog[]): Promise<void>;
insert(log: EventLog): Promise<EventLog>;
queryDau(eventName: EventName, start: Date, end: Date): Promise<DauQueryResult>;
}
// 模块配置 (infrastructure/infrastructure.module.ts)
@Module({
providers: [
{
provide: EVENT_LOG_REPOSITORY,
useClass: EventLogRepositoryImpl,
},
],
exports: [EVENT_LOG_REPOSITORY],
})
export class InfrastructureModule {}
// 使用 (application/commands/)
@CommandHandler(RecordHeartbeatCommand)
export class RecordHeartbeatHandler {
constructor(
@Inject(EVENT_LOG_REPOSITORY)
private readonly eventLogRepo: IEventLogRepository,
) {}
}
```
---
## 8. 错误处理
### 8.1 领域异常
```typescript
// 基础领域异常
export abstract class DomainException extends Error {
abstract readonly code: string;
}
// 具体异常
export class InvalidInstallIdException extends DomainException {
code = 'INVALID_INSTALL_ID';
}
export class InvalidEventNameException extends DomainException {
code = 'INVALID_EVENT_NAME';
}
```
### 8.2 全局异常过滤器
```typescript
@Catch()
export class GlobalExceptionFilter implements ExceptionFilter {
catch(exception: unknown, host: ArgumentsHost) {
// HttpException -> 原样返回状态码
// DomainException -> 400 Bad Request
// Unknown -> 500 Internal Server Error (生产环境隐藏详情)
}
}
```
---
## 9. 跨切关注点
### 9.1 日志
- 使用 NestJS 内置 Logger
- LoggingInterceptor 记录请求/响应
- 结构化日志格式
### 9.2 监控指标
- 请求延迟 (P50/P95/P99)
- 在线用户数
- 心跳 QPS
- 错误率
### 9.3 健康检查
```
GET /api/v1/health
{
"status": "ok",
"service": "presence-service",
"timestamp": "2025-01-01T00:00:00Z"
}
```

## 4. 编码规范
### 4.1 DDD 原则
#### 领域层规则
1. **不依赖任何框架** - 领域层只使用纯 TypeScript
2. **聚合根保护内部状态** - 通过方法修改状态，不直接暴露属性
3. **值对象不可变** - 创建后不能修改
4. **领域服务无状态** - 不持有任何状态
```typescript
// ✅ 好的做法 - 值对象不可变
export class InstallId {
private constructor(private readonly _value: string) {}
static fromString(value: string): InstallId {
// 校验逻辑
return new InstallId(value);
}
get value(): string {
return this._value;
}
}
// ❌ 不好的做法 - 值对象可变
export class InstallId {
public value: string; // 可以被外部修改
}
```
#### 聚合根设计
```typescript
// ✅ 好的做法 - 聚合根保护内部状态
export class DailyActiveStats {
private _dauCount: number;
updateStats(count: number): void {
if (count < 0) {
throw new InvalidDauCountException();
}
this._dauCount = count;
this.incrementVersion();
}
get dauCount(): number {
return this._dauCount;
}
}
// ❌ 不好的做法 - 直接暴露内部状态
export class DailyActiveStats {
public dauCount: number; // 外部可以直接修改
}
```
### 4.2 CQRS 规范
#### Command 设计
```typescript
// Command 只包含执行操作所需的数据
export class RecordHeartbeatCommand {
constructor(
public readonly userId: bigint,
public readonly installId: string,
public readonly appVersion: string,
public readonly clientTs: number,
) {}
}
// Handler 负责业务编排
@CommandHandler(RecordHeartbeatCommand)
export class RecordHeartbeatHandler implements ICommandHandler<RecordHeartbeatCommand> {
async execute(command: RecordHeartbeatCommand): Promise<void> {
// 1. 验证
// 2. 执行业务逻辑
// 3. 持久化
// 4. 发布事件
}
}
```
#### Query 设计
```typescript
// Query 只包含查询条件
export class GetOnlineCountQuery {
constructor(
public readonly windowSeconds: number = 180,
) {}
}
// Handler 返回查询结果
@QueryHandler(GetOnlineCountQuery)
export class GetOnlineCountHandler implements IQueryHandler<GetOnlineCountQuery, OnlineCountResult> {
async execute(query: GetOnlineCountQuery): Promise<OnlineCountResult> {
// 直接读取数据，不修改状态
}
}
```
### 4.3 依赖注入
```typescript
// 1. 定义接口和 Token (domain/repositories/)
export const EVENT_LOG_REPOSITORY = Symbol('EVENT_LOG_REPOSITORY');
export interface IEventLogRepository {
insert(log: EventLog): Promise<EventLog>;
}
// 2. 实现接口 (infrastructure/persistence/repositories/)
@Injectable()
export class EventLogRepositoryImpl implements IEventLogRepository {
async insert(log: EventLog): Promise<EventLog> {
// 具体实现
}
}
// 3. 配置绑定 (infrastructure/infrastructure.module.ts)
@Module({
providers: [
{
provide: EVENT_LOG_REPOSITORY,
useClass: EventLogRepositoryImpl,
},
],
})
// 4. 使用 (application/commands/)
@CommandHandler(SomeCommand)
export class SomeHandler {
constructor(
@Inject(EVENT_LOG_REPOSITORY)
private readonly repo: IEventLogRepository,
) {}
}
```
### 4.4 错误处理
```typescript
// 1. 定义领域异常 (domain/exceptions/)
export class InvalidInstallIdException extends DomainException {
constructor(value: string) {
super(`Invalid install ID: ${value}`);
}
get code(): string {
return 'INVALID_INSTALL_ID';
}
}
// 2. 在值对象中使用
export class InstallId {
static fromString(value: string): InstallId {
if (!this.isValid(value)) {
throw new InvalidInstallIdException(value);
}
return new InstallId(value);
}
}
// 3. GlobalExceptionFilter 自动处理
// DomainException -> 400 Bad Request
```

## 6. 开发流程
### 6.1 新增功能流程
1. **领域建模**
- 识别聚合、实体、值对象
- 定义领域服务
- 设计仓储接口
2. **编写领域层代码**
- 创建值对象 (`domain/value-objects/`)
- 创建实体/聚合 (`domain/entities/`, `domain/aggregates/`)
- 创建领域服务 (`domain/services/`)
- 定义仓储接口 (`domain/repositories/`)
3. **编写应用层代码**
- 创建 Command/Query (`application/commands/`, `application/queries/`)
- 创建 Handler
4. **编写基础设施层代码**
- 创建 Mapper (`infrastructure/persistence/mappers/`)
- 实现仓储 (`infrastructure/persistence/repositories/`)
5. **编写 API 层代码**
- 创建 DTO (`api/dto/`)
- 创建 Controller (`api/controllers/`)
6. **编写测试**
- 单元测试 (领域层)
- 集成测试 (应用层)
- E2E 测试 (API 层)
### 6.2 代码审查清单
- [ ] 领域层是否无框架依赖？
- [ ] 值对象是否不可变？
- [ ] 聚合根是否保护了内部状态？
- [ ] 仓储接口是否定义在领域层？
- [ ] Command/Query 是否职责单一？
- [ ] 是否有充分的测试覆盖？
- [ ] 异常处理是否完善？
- [ ] 是否遵循命名规范？

## 7. 调试技巧
### 7.1 VS Code 调试配置
`.vscode/launch.json`:
```json
{
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug NestJS",
"runtimeExecutable": "npm",
"runtimeArgs": ["run", "start:debug"],
"console": "integratedTerminal",
"restart": true,

"request": "launch",
"name": "Debug Jest Tests",
"runtimeExecutable": "npm",
"runtimeArgs": ["run", "test:debug"],
"console": "integratedTerminal"
}
]
}
```
### 7.2 日志调试
```typescript
import { Logger } from '@nestjs/common';
const logger = new Logger('MyService');
logger.log('Info message');
logger.warn('Warning message');
logger.error('Error message', error.stack);
logger.debug('Debug message'); // 需要设置 LOG_LEVEL=debug
```
### 7.3 Prisma 调试
```bash
# 启用查询日志
DEBUG="prisma:query" npm run start:dev
# 或在 schema.prisma 中配置
generator client {
provider = "prisma-client-js"
previewFeatures = ["tracing"]
}
```

## 3. 单元测试
### 3.1 测试目标
单元测试覆盖**领域层**的核心业务逻辑：
- 值对象的创建和校验
- 实体的行为和状态变化
- 聚合根的业务规则
- 领域服务的计算逻辑
### 3.2 测试原则
1. **隔离性**: 不依赖外部服务（数据库、Redis、网络）
2. **快速性**: 毫秒级执行
3. **可重复性**: 每次执行结果一致
4. **自包含**: 不依赖其他测试的状态
### 3.3 示例：值对象测试
```typescript
// test/unit/domain/value-objects/install-id.vo.spec.ts
import { InstallId } from '@/domain/value-objects/install-id.vo';
describe('InstallId', () => {
describe('fromString', () => {
it('should create InstallId with valid value', () => {
const installId = InstallId.fromString('valid-install-id-123');
expect(installId.value).toBe('valid-install-id-123');
});
it('should throw error for empty value', () => {
expect(() => InstallId.fromString('')).toThrow();
});
it('should throw error for value shorter than 8 characters', () => {
expect(() => InstallId.fromString('short')).toThrow();
});
it('should throw error for value longer than 64 characters', () => {
const longValue = 'a'.repeat(65);
expect(() => InstallId.fromString(longValue)).toThrow();
});
it('should throw error for value with invalid characters', () => {
expect(() => InstallId.fromString('invalid@id#123')).toThrow();
});
});
describe('equals', () => {
it('should return true for same value', () => {
const id1 = InstallId.fromString('test-install-id');
const id2 = InstallId.fromString('test-install-id');
expect(id1.equals(id2)).toBe(true);
});
it('should return false for different values', () => {
const id1 = InstallId.fromString('test-install-id-1');
const id2 = InstallId.fromString('test-install-id-2');
expect(id1.equals(id2)).toBe(false);
});
});
});
```
### 3.4 示例：领域服务测试
```typescript
// test/unit/domain/services/online-detection.service.spec.ts
import { OnlineDetectionService } from '@/domain/services/online-detection.service';
describe('OnlineDetectionService', () => {
let service: OnlineDetectionService;
beforeEach(() => {
service = new OnlineDetectionService();
});
describe('isOnline', () => {
it('should return true when heartbeat is within window', () => {
const now = Date.now();
const lastHeartbeat = new Date(now - 60 * 1000); // 1 minute ago
const windowSeconds = 180; // 3 minutes
expect(service.isOnline(lastHeartbeat, windowSeconds)).toBe(true);
});
it('should return false when heartbeat is outside window', () => {
const now = Date.now();
const lastHeartbeat = new Date(now - 200 * 1000); // 200 seconds ago
const windowSeconds = 180; // 3 minutes
expect(service.isOnline(lastHeartbeat, windowSeconds)).toBe(false);
});
it('should return true for heartbeat exactly at window boundary', () => {
const now = Date.now();
const lastHeartbeat = new Date(now - 180 * 1000); // exactly 3 minutes ago
const windowSeconds = 180;
expect(service.isOnline(lastHeartbeat, windowSeconds)).toBe(true);
});
});
describe('calculateThresholdTime', () => {
it('should calculate correct threshold time', () => {
jest.useFakeTimers();
const now = new Date('2025-01-01T12:00:00Z');
jest.setSystemTime(now);
const threshold = service.calculateThresholdTime(180);
expect(threshold.getTime()).toBe(now.getTime() - 180 * 1000);
jest.useRealTimers();
});
});
});
```
### 3.5 示例：聚合根测试
```typescript
// test/unit/domain/aggregates/daily-active-stats.aggregate.spec.ts
import { DailyActiveStats } from '@/domain/aggregates/daily-active-stats/daily-active-stats.aggregate';
describe('DailyActiveStats', () => {
describe('create', () => {
it('should create new stats with initial values', () => {
const day = new Date('2025-01-01');
const stats = DailyActiveStats.create(day);
expect(stats.day).toEqual(day);
expect(stats.dauCount).toBe(0);
expect(stats.version).toBe(1);
});
});
describe('updateStats', () => {
it('should update dau count and increment version', () => {
const stats = DailyActiveStats.create(new Date('2025-01-01'));
const byProvince = new Map([['广东省', 1000]]);
const byCity = new Map([['深圳市', 500]]);
stats.updateStats(5000, byProvince, byCity);
expect(stats.dauCount).toBe(5000);
expect(stats.dauByProvince.get('广东省')).toBe(1000);
expect(stats.dauByCity.get('深圳市')).toBe(500);
expect(stats.version).toBe(2);
});
it('should throw error for negative count', () => {
const stats = DailyActiveStats.create(new Date('2025-01-01'));
expect(() => stats.updateStats(-1, new Map(), new Map())).toThrow();
});
});
describe('reconstitute', () => {
it('should reconstitute from persistence data', () => {
const data = {
day: new Date('2025-01-01'),
dauCount: 5000,
dauByProvince: new Map([['广东省', 1000]]),
dauByCity: new Map([['深圳市', 500]]),
calculatedAt: new Date(),
version: 3,
};
const stats = DailyActiveStats.reconstitute(data);
expect(stats.dauCount).toBe(5000);
expect(stats.version).toBe(3);
});
});
});
```

## 9. 测试最佳实践
### 9.1 命名规范
```typescript
describe('ClassName/FunctionName', () => {
describe('methodName', () => {
it('should <expected behavior> when <condition>', () => {
// Arrange - Given
// Act - When
// Assert - Then
});
});
});
```
### 9.2 AAA 模式
```typescript
it('should calculate correct DAU count', () => {
// Arrange (Given)
const events = [createEvent('user1'), createEvent('user2')];
const service = new DauCalculationService();
// Act (When)
const result = service.calculateDau(events);
// Assert (Then)
expect(result.total).toBe(2);
});
```
### 9.3 避免测试反模式
```typescript
// ❌ 测试实现细节
it('should call repository.save once', () => {
expect(mockRepo.save).toHaveBeenCalledTimes(1);

# Presence Service 脚本说明
## 脚本列表
| 脚本 | 用途 | 使用场景 |
|-----|------|---------|
| `start-all.sh` | 一键启动所有服务 | 开发环境初始化 |
| `stop-service.sh` | 停止 Presence Service | 重启服务、关闭开发环境 |
| `health-check.sh` | 检查所有服务健康状态 | 部署验证、故障排查 |
---
## 快速开始
### 1️⃣ 一键启动（推荐）
```bash
./scripts/start-all.sh
```
这个脚本会：
1. ✅ 启动 Docker 容器 (PostgreSQL, Redis, Kafka)
2. ✅ 等待所有基础设施就绪
3. ✅ 初始化数据库 (Prisma)
4. ✅ 启动 Presence Service
5. ✅ 验证服务可用
### 2️⃣ 健康检查
```bash
./scripts/health-check.sh
```
**期望输出：**
```
🏥 Starting health check...
=== Database Service ===
Checking PostgreSQL ... ✓ OK
=== Cache Service ===
Checking Redis ... ✓ OK
=== Message Queue Service ===
Checking Kafka ... ✓ OK
=== Application Service ===
Checking Presence Service ... ✓ OK
======================================
Health Check Complete!
Passed: 4
Failed: 0
======================================
✓ All services are healthy!
```
### 3️⃣ 停止服务
```bash
./scripts/stop-service.sh
```
---
## 服务端口
| 服务 | 开发端口 | 说明 |
|-----|---------|------|
| Presence Service | 3001 | NestJS 应用 |
| PostgreSQL | 5432 | 数据库 |
| Redis | 6379 | 缓存 |
| Kafka | 9092 | 消息队列 |
| Zookeeper | 2181 | Kafka 协调 |
---
## 手动操作
### 只启动基础设施
```bash
docker compose -f docker-compose.dev.yml up -d
```
### 只启动应用
```bash
npm run start:dev
```
### 停止所有容器
```bash
docker compose -f docker-compose.dev.yml down
```
### 清理数据
```bash
# 停止容器并删除数据卷
docker compose -f docker-compose.dev.yml down -v
```
---
## 故障排查
### PostgreSQL 连接失败
```bash
# 检查容器状态
docker ps -a | grep presence-postgres
# 查看日志
docker logs presence-postgres-dev
# 重启容器
docker compose -f docker-compose.dev.yml restart postgres
```
### Redis 连接失败
```bash
# 检查容器状态
docker ps -a | grep presence-redis
# 测试连接
docker exec presence-redis-dev redis-cli ping
# 重启容器
docker compose -f docker-compose.dev.yml restart redis
```
### Kafka 连接失败
```bash
# Kafka 启动较慢，等待 30-60 秒
docker logs presence-kafka-dev
# 检查 Zookeeper
docker exec presence-zookeeper-dev nc -z localhost 2181
# 重启 Kafka 和 Zookeeper
docker compose -f docker-compose.dev.yml restart zookeeper kafka
```
### 端口冲突
```bash
# 查找占用端口的进程
lsof -i :3001
lsof -i :5432
lsof -i :6379
lsof -i :9092
# 停止冲突进程
kill <PID>
```
---
## Windows 用户
这些脚本是 Bash 脚本，在 Windows 上需要：
1. **Git Bash** (推荐)
2. **WSL (Windows Subsystem for Linux)**
3. **Docker Desktop** (已包含 Linux 环境)
```powershell
# 使用 Git Bash 运行
bash ./scripts/start-all.sh
# 或者直接使用 npm 命令
npm run start:dev
```
---
## 完整开发流程
```bash
# 1. 克隆项目
git clone <repository-url>
cd backend/services/presence-service
# 2. 安装依赖
npm install
# 3. 复制环境配置
cp .env.example .env.development
# 4. 启动所有服务
./scripts/start-all.sh
# 5. 运行健康检查
./scripts/health-check.sh
# 6. 运行测试
npm test
npm run test:e2e
# 7. 开发完成后停止
./scripts/stop-service.sh
docker compose -f docker-compose.dev.yml down
```
