# Echo Nexus · 云排行榜 mini-service
回响星核 / Echo Nexus 的 P2 云排行榜服务(v0.8.2 / Task 10-b)。
把信标本机排行榜(`localStorage`)升级为云端 Top100,玩家间可比。
## 技术栈
- **运行时**Bun(原生 TypeScript,无需编译)
- **框架**Hono(轻量 web 框架,bun 原生支持)
- **存储**:内存数组,重启清空(够用,符合 P2 规格)
- **端口**:固定 `3030`Caddy 通过 `?XTransformPort=3030` 转发)
## 目录结构
```
mini-services/leaderboard-service/
├── package.json # 独立 bun 项目
├── index.ts # Hono 入口
└── README.md
```
## API
所有响应自动 CORS 开放,OPTIONS 预检由 Hono 自动处理。
| 方法 | 路径 | 入参 | 返回 |
|---|---|---|---|
| GET | `/` | — | `{ service, version, ok, uptime }` 健康检查 |
| GET | `/api/leaderboard` | — | `{ entries: BeaconScoreEntry[], total }` Top100 |
| POST | `/api/leaderboard` | body `{ entry: BeaconScoreEntry }` | `{ entries, total, rank }` rank=1..N 或 -1 |
| GET | `/api/leaderboard/stats` | — | `{ totalSubmissions, uniquePlayers, topScore }` |
### `BeaconScoreEntry` 结构
```ts
{
timestamp: number, // 提交时间戳
dateKey: string, // YYYY-MM-DD 或 YYYY-Www
challenge: string, // decode | expedition | pulse | boss | insight
difficulty: string, // routine | anomaly | singular
progress: number, // 0-11 = 完成
score: number, // 最终得分
durationSec: number, // 完成时长(秒)
isWeekly?: boolean, // 周挑战记录
isTimed?: boolean // 限时挑战记录(预留)
}
```
## 存储 & 防刷规则
- **容量**:最多 1000 条,按分数降序;超过自动丢弃尾部。
- **Top 榜**API 返回前 100 条。
- **同分排序**:先看用时短,再看提交早。
- **防刷**:同 `dateKey + challenge` 10 秒内只接受 1 次提交,返回 `429`
## 启动
```bash
cd mini-services/leaderboard-service
bun run dev
# 等价于 bun --hot index.ts,文件变更自动重启
```
## 联调(前端请求规范)
前端必须用相对路径 + `?XTransformPort=3030`
```ts
// 拉取全球 Top100
const res = await fetch("/api/leaderboard?XTransformPort=3030");
const { entries, total } = await res.json();
// 提交一条记录
const res = await fetch("/api/leaderboard?XTransformPort=3030", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ entry }),
});
const { entries, total, rank } = await res.json();
```
**禁止** `fetch("http://localhost:3030/...")` —— 不通过 Caddy 网关,会被浏览器同源策略拦截。
## 部署形态
独立 bun 项目,与主 Next.js 项目解耦:
- 主项目端口 3000Next.js dev
- 本服务端口 3030Hono + Bun
- Caddy 网关端口 81(按 `?XTransformPort=3030` 转发到本服务)
服务重启会清空数据,符合 P2 阶段规格(不需要持久化)。
