### 1.1 MF 拓扑选型
|
||
|
||
| 方案 | 选否 | 理由 |
|
||
| ------------------------------------ | ---- | --------------------------------------------------------------------------------------- |
|
||
| 4 端独立部署 + 独立域名 + 各自 Shell | ❌ | 4 套 Shell 重复,登录态/权限/组件库/GraphQL client 要重复实现 |
|
||
| 单 Shell + 4 Remote(**采用**) | ✅ | teacher-portal 作为 Shell 宿主,提供 AppShell + GraphQLProvider 单例 + 共享依赖;其余 3 端作为 Remote 动态加载 |
|
||
| 单一 Next.js 应用 + 4 路由组 | ❌ | 违反"微前端独立部署"目标(ADR-012) |
|
||
|
||
**Shell 职责**(teacher-portal,ARB-002 §2.2):
|
||
|
||
- RootLayout(字体、设计令牌、i18n Provider、GraphQLProvider、Zustand StoreProvider)
|
||
- AppShell(左侧导航 + 主内容区 + 用户信息 + 登出 + 路由守卫)
|
||
- GraphQLProvider(urql client 单例,总裁 §2.17 方案 A,Remote 复用)
|
||
- 共享依赖暴露(react、react-dom、urql、graphql、@edu/ui-tokens、@edu/ui-components、@edu/hooks)
|
||
- 路由表(4 端路由前缀:`/teacher/*`、`/student/*`、`/parent/*`、`/admin/*`)
|
||
- 登录页(统一登录入口 `POST /api/auth/login`,非 MF,登录是认证前提)
|
||
|
||
### 1.2 MF 配置(teacher-portal/next.config.js,ARB-002 §2.2 裁决)
|
||
|
||
```javascript
|
||
// teacher-portal/next.config.js(Shell,ARB-002 第一版暴露清单)
|
||
const NextFederationPlugin = require("@module-federation/nextjs-mf");
|
||
|
||
// P2:remotes 为空(NEXT_PUBLIC_MF_ENABLED=false,ARB-002 §2.3),P3+ 逐步接入
|
||
const remotes = (isServer) => {
|
||
if (process.env.NEXT_PUBLIC_MF_ENABLED !== "true") return {};
|
||
return {
|
||
student: `student_app@http://localhost:4001/_next/static/${isServer ? "ssr" : "chunks"}/remoteEntry.js`,
|
||
parent: `parent_app@http://localhost:4002/_next/static/${isServer ? "ssr" : "chunks"}/remoteEntry.js`,
|
||
admin: `admin_app@http://localhost:4003/_next/static/${isServer ? "ssr" : "chunks"}/remoteEntry.js`,
|
||
};
|
||
};
|
||
|
||
module.exports = {
|
||
reactStrictMode: true,
|
||
webpack(config, { isServer }) {
|
||
config.plugins.push(
|
||
new NextFederationPlugin({
|
||
name: "teacher_app",
|
||
filename: "static/chunks/remoteEntry.js",
|
||
remotes: remotes(isServer), // P2 为 {},ARB-002 §2.3
|
||

||
);
|

||
async rewrites() {

||
return [

|
||
destination: `${process.env.API_GATEWAY_URL || "http://localhost:8080"}/api/v1/:path*`,
|
||
},
|
||
];
|
||
},
|
||
};
|
||
```
|
||
|
||
> **P2 Remote 数量 = 0**(ARB-002 §2.3,`NEXT_PUBLIC_MF_ENABLED=false` 默认关)。P3 student-portal 作为首个 Remote 接入(总裁 §1.3 step 4)。feature flag 控制回退单体路由。
|
||
|
||
## 2. 领域模型(前端视角)
|
||
|
||
前端不持有业务聚合根,仅持有"视图模型"(ViewModel)和"会话状态"。数据来源统一为 teacher-bff GraphQL(F9 裁决)。
|
||
|
||
### 2.1 会话状态(Session)
|
||
|
||
```typescript
|
||
interface Session {
|
||
user: UserInfo; // { id, email, name, roles, dataScope }(GraphQL me Query)
|
||
tokens: { accessToken: string; refreshToken: string }; // F12: localStorage(P6 迁移 cookie)
|
||
viewports: ViewportItem[]; // L1 导航视口(GraphQL viewports Query)
|
||
permissions: string[]; // 权限点(GraphQL me Query 内嵌或 effective-permissions)
|
||
expiresAt: number; // access token 过期时间戳
|
||
}
|
||
```
|
||
|
||
存储:Zustand sessionSlice(L3)+ localStorage 持久化(刷新恢复,F12)+ urql cache(L2,GraphQL document cache)。
|
||
|
||
### 2.2 视口模型(Viewport)
|
||
|
||
```typescript
|
||
// 对齐 ARB-001 §1.2 schema:ViewportItem
|
||
interface ViewportItem {
|
||
key: string; // 'dashboard' | 'classes' | ...
|
||
label: string; // i18n key 或显式文案
|
||
route: String; // '/teacher/dashboard'(schema 为 String)
|
||
icon: String | null; // 图标 key(schema 可空)
|
||
sortOrder: String; // 排序(schema 为 String)
|
||
requiredPermission: String | null; // 'CLASSES_READ' 等
|
||
}
|
||
```
|
||
|
||
来源:GraphQL `viewports` Query(ARB-001 §1.2)。AppShell 按 `requiredPermission` + `usePermission().hasPermission()` 过滤渲染导航。
|
||
|
||
### 2.3 权限模型(Permission)
|
||
|
||
```typescript
|
||
interface PermissionState {
|
||
permissions: string[]; // ['CLASSES_READ', 'EXAMS_CREATE', ...](GraphQL me Query 返回)
|
||
dataScope: DataScope; // SELF | CLASS | GRADE | SCHOOL | DISTRICT | ALL(ARB-001 enum)
|
||
hasPermission: (perm: string) => boolean;
|
||
hasAnyPermission: (perms: string[]) => boolean;
|
||
hasAllPermissions: (perms: string[]) => boolean;
|
||
}
|
||
```
|
||
|
||
来源:GraphQL `me` Query 返回 `{ user, roles, dataScope }`(ARB-001 §1.2)。角色变更由 iam 发 Kafka → msg → push-gateway WebSocket 推送 → 前端 invalidate urql cache(见 [03 §2.5](./03-long-term-architecture.md))。
|
||
|
||
## 3. 数据模型(前端缓存层)
|
||
|
||
前端无数据库,仅有 urql 缓存层(03 §1.4.4 缓存策略):
|
||
|
||
| 数据类型 | 存储 | staleTime | 失效策略 |
|
||
| ----------------------- | ----------------------------- | ---------------------------------- | --------------------------------------------- |
|
||
| Session(token + user) | localStorage + Zustand(F12) | access 15min / refresh 7day | 401 自动 refresh,refresh 失败跳登录 |
|
||
| 权限列表 + 视口 | urql cacheExchange | 0(always fetch) | 角色变更 WebSocket 推送后强制 invalidate |
|
||
| 班级/年级列表 | urql cacheExchange | 30s | mutation 后 invalidate |
|
||
| 考试/作业/成绩 | urql cacheExchange | 10s | mutation 后 invalidate + 乐观更新(03 §10.1) |
|
||
| 教学资源详情 | urql cacheExchange | 30s | staleTime 30s |
|
||
| 学情宽表 | urql cacheExchange | 60s | ISR revalidate 60s + CSR 交互 |
|
||
| URL 状态(分页/筛选) | nuqs | — | 永久(可分享) |
|
||
| 表单临时态 | react-hook-form | — | 卸载即销毁 |
|
||
|
||
> urql 默认 document cache 适合简单场景;复杂关联(班级↔考试↔成绩)P3 起评估切 `@urql/exchange-graphcache` normalized cache(03 §1.4.4)。不引入 TanStack Query 做 GraphQL 缓存(避免双缓存层);TanStack Query 仅用于非 GraphQL 场景(文件上传/SSE)。
|
||
|
||
## 4. API 设计(前端 → teacher-bff GraphQL)
|
||
|
||
F9 裁决:P2 起 all-in GraphQL。前端不再设计 REST 请求层,统一通过 urql client 消费 teacher-bff GraphQL(ARB-001 schema 第一版)。
|
||
|
||
### 4.1 urql client 单例(packages/hooks + Shell GraphQLProvider)
|
||
|
||
```typescript
|
||
// packages/hooks/src/use-graphql-client.ts(Shell 暴露,Remote 复用,ARB-002 §2.17 方案 A)
|
||
import { createClient, Client } from "urql";
|
||
import { cacheExchange, fetchExchange } from "urql";
|
||
|
||
const client: Client = createClient({
|
||
url: process.env.NEXT_PUBLIC_TEACHER_BFF_GRAPHQL_URL!, // teacher-bff POST /graphql(经 api-gateway 代理)
|
||
fetchOptions: () => {
|
||
const token = readAuthToken(); // useAuth 注入(F12: localStorage)
|
||
const traceId = readTraceId();
|
||
return {
|
||
headers: {
|
||
...(token ? { Authorization: `Bearer ${token}` } : {}),
|
||
"X-Trace-Id": traceId,
|
||
},
|
||
};
|
||
},
|
||
exchanges: [cacheExchange, fetchExchange],
|
||
});
|
||
|
||
// Shell: src/app/providers.tsx 包裹 <Provider value={client}>,所有 Remote 复用同一 client
|
||
```
|
||
|
||
**职责**:
|
||
|
||
- Shell 初始化 urql client 单例,通过 React Context 注入给所有 Remote(ARB-002 方案 A)
|
||
- token 刷新/401 处理由 useAuth 统一拦截(不污染 urql exchange 链,见 [03 §2.7](./03-long-term-architecture.md))
|
||
- MF shared singleton(react/urql/graphql)避免 Remote 多实例 + 缓存不一致
|
||
- 请求/响应 trace_id 透传(`X-Trace-Id` header)
|
||
|
||
### 4.2 GraphQL Query/Mutation 约定(对齐 ARB-001 schema)
|
||
|
||
```typescript
|
||
// P2 Query(ARB-001 §1.2,5 个 Must Have)
|
||
import { gql } from "urql";
|
||
|
||
const DashboardQuery = gql`
|
||
query Dashboard {
|
||
dashboard {
|
||
user { id email name roles dataScope }
|
||
classes { id name gradeId studentCount }
|
||
viewports { key label route icon sortOrder requiredPermission }
|
||
stats { totalExams pendingGrading todayHomework }
|
||
}
|
||
}
|
||
`;
|
||
|
||
const ViewportsQuery = gql`query { viewports { key label route icon sortOrder requiredPermission } }`;
|
||
const MeQuery = gql`query { me { id email name roles dataScope } }`;
|
||
const ClassesQuery = gql`query { classes { id name gradeId studentCount } }`;
|
||
|
||
// P3+ Mutation(ARB-001 §1.2 P2 不包含)
|
||
const CreateExamMutation = gql`
|
||
mutation CreateExam($input: CreateExamInput!) {
|
||
createExam(input: $input) { ... on ExamCreated { id } }
|
||
}
|
||
`;
|
||
```
|
||
|
||
**urql mutation + 乐观更新**:
|
||
|
||
```typescript
|
||
const [, createExam] = useMutation(CreateExamMutation);
|
||
// 乐观更新:onMutate 回滚 + invalidateQueries(见 03 §10.1)
|
||
```
|
||
|
||
### 4.3 错误处理(ActionState 信封 + GraphQL errors,ARB-001 §1.3)
|
||
|
||
| 场景 | 处理 |
|
||
| ------------------------------ | --------------------------------------------------------------------------------------------------------------- |
|
||
| GraphQL 错误(errors[]) | 解析 `extensions.code`(BFF_TEACHER_* 前缀,G14),映射到 i18n key `error.teacher_bff.<code_snake>`(F11) |
|
||
| 网络错误 | 重试 1 次 → 提示网络异常 → 记录 trace_id |
|
||
| 401 | useAuth 静默 refresh 一次 → 重试;失败跳登录(见 03 §2.7) |
|
||
| 部分失败(data + errors 共存) | 渲染 data 可用部分 + errors 区域提示,不整体失败(ARB-001 §1.3 降级模式方案 B) |
|
||
|
||
- BFF 始终返回 `ActionState` 信封(004 §11.5),前端统一走 `normalizeActionState()` 工具(packages/hooks)
|
||
|
||
## 5. 事件设计
|
||
|
||
前端不发布 Kafka 事件,仅消费 WebSocket 推送(P5)和 Server-Sent Events(AI 流式)。
|
||
|
||
### 5.1 WebSocket 推送(P5)
|
||
|
||
| 事件 | 触发 | teacher-portal 前端动作 |
|
||
| ----------------------- | ------------ | ----------------------------------------------- |
|
||
| `NotificationRequested` | msg 服务投递 | toast 提示 + 通知中心未读数 +1 |
|
||
| `HomeworkSubmitted` | 学生提交作业 | toast + urql cache invalidate 作业批改列表 |
|
||
| 角色变更(iam) | iam Kafka | urql cache invalidate 权限/视口(强制刷新 me Query) |
|
||
|
||
### 5.2 SSE 流式(P5 AI 辅助出题)
|
||
|
||
```
|
||
GET /api/v1/ai/generate-questions (SSE) 或 GraphQL Subscription(P6+ 评估)
|
||
data: {"delta": "题目"}\n\n
|
||
data: {"done": true}\n\n
|
||
```
|
||
|
||
前端用 `AsyncIterable<T>` 消费(非 GraphQL,TanStack Query 场景),Tiptap 逐字插入。
|
||
|
||
## 6. 横切关注点对齐清单
|
||
|
||
### 6.1 权限(前端等价,F7 命名 `<RESOURCE>_<ACTION>`)
|
||
|
||
| 路由 | requiredPermission |
|
||
| ----------------------------- | ------------------------ |
|
||
| `/teacher/dashboard` | `TEACHER_DASHBOARD_VIEW` |
|
||
| `/teacher/classes` | `CLASSES_READ` |
|
||
| `/teacher/classes/new` | `CLASSES_CREATE` |
|
||
| `/teacher/exams` | `EXAMS_READ` |
|
||
| `/teacher/exams/new` | `EXAMS_CREATE` |
|
||
| `/teacher/homework` | `HOMEWORK_READ` |
|
||
| `/teacher/homework/:id/grade` | `HOMEWORK_GRADE` |
|
||
| `/teacher/grades` | `GRADES_READ` |
|
||
| `/teacher/ai-assist` | `AI_GENERATE` |
|
||
| `/teacher/lesson-prep` | `LESSON_PREP_VIEW` |
|
||
| `/teacher/knowledge-graph` | `CONTENT_READ` |
|
||
|
||
> 完整权限点常量集中在 `packages/contracts/src/permissions.ts`(coord 维护,ai13 消费)。L3 组件级视口用 `<RequirePermission perm="EXAMS_CREATE"><Button>新建考试</Button></RequirePermission>`。
|
||
|
||
### 6.2 错误码清单(前端 i18n 路由,对齐 [matrix.md §6](../../../docs/architecture/issues/matrix.md))
|
||
|
||
| 前缀 | 来源服务 | i18n key 模式 |
|
||
| -------------- | ----------- | ------------------------ |
|
||
| `IAM_` | iam | `iam.error.{{code}}` |
|
||
| `CORE_EDU_` | core-edu | `coreEdu.error.{{code}}` |
|
||
| `CLASSES_` | core-edu | `classes.error.{{code}}` |
|
||
| `CONTENT_` | content | `content.error.{{code}}` |
|
||
| `MSG_` | msg | `msg.error.{{code}}` |
|
||
| `AI_` | ai | `ai.error.{{code}}` |
|
||
| `BFF_TEACHER_` | teacher-bff | `error.teacher_bff.{{code_snake}}` |
|
||
| `GW_` | api-gateway | `gateway.error.{{code}}` |
|
||
| `NETWORK_` | 前端网络层 | `network.error.{{code}}` |
|
||
|
||
### 6.3 Logger
|
||
|
||
```typescript
|
||
// packages/shared-ts/src/logger.ts
|
||
interface Logger {
|
||
info(msg: string, meta?: Record<string, unknown>): void;
|
||
warn(msg: string, meta?: Record<string, unknown>): void;
|
||
error(msg: string, meta?: Record<string, unknown>): void;
|
||
}
|
||
// 实现:开发环境 console + 结构化;生产环境 → Sentry(P6)
|
||
// 必含字段:trace_id(从响应头提取)、user_id、scope、path
|
||
```
|
||
|
||
### 6.4 Metrics(Web Vitals)
|
||
|
||
| 指标 | 类型 | 上报 |
|
||
| ----------------------------- | ---- | --------------------------------------------------- |
|
||
| `teacher_portal_lcp_seconds` | LCP | `next/web-vitals` → `POST /api/v1/admin/web-vitals` |
|
||
| `teacher_portal_cls` | CLS | 同上 |
|
||
| `teacher_portal_inp_seconds` | INP | 同上 |
|
||
| `teacher_portal_ttfb_seconds` | TTFB | 同上 |
|
||
|
||
P6 接入,P2-P5 暂缓。
|
||
|
||
### 6.5 Tracer(OTel browser SDK,P6)
|
||
|
||
```typescript
|
||
// packages/shared-ts/src/tracer.ts
|
||
import { WebTracerProvider } from "@opentelemetry/sdk-trace-web";
|
||
// BatchSpanProcessor → OTLP exporter → collector → Tempo
|
||
// 自动埋点:fetch、XMLHttpRequest、document load、user interaction
|
||
```
|
||
|
||
### 6.6 健康检查
|
||
|
||
| 端点 | 用途 | 实现 |
|
||
| ----------------- | ---------------------- | -------------------------------------------------------------- |
|
||
| `GET /api/health` | Dockerfile HEALTHCHECK | Next.js Route Handler,返回 `{ status: 'ok', ts: Date.now() }` |
|
||
| `GET /api/ready` | K8s readinessProbe | 检查 `process.env.API_GATEWAY_URL` 可达 + 内存 < 阈值 |
|
||
|
||
### 6.7 优雅关闭
|
||
|
||
Next.js 无长连接(除 SSE/WS),无需特殊处理。SSE/WS 在 P5 由 push-gateway 管理,前端断线自动重连。
|
||
|

## 7. 共享组件库(packages/ui-components/,ai13 维护,ARB-002 暴露)
|
||
|
||
| 组件 | 用途 | MF 暴露(ARB-002) |
|
||
| ------------------------------------------ | --------------------------------------------------------------------------------------------------- | ------------------ |
|
||
| `AppShell` | 左侧栏 + 主内容区布局 | ✅ `./AppShell` |
|
||
| `RequirePermission` | L3 组件级视口控制(无权限不渲染 children) | ✅ `./RequirePermission` |
|
||
| `ErrorBoundary` | React 渲染异常兜底(fallback UI) | ✅ `./ErrorBoundary` |
|
||
| `Loading` | 骨架屏(Skeleton) | ✅ `./Loading` |
|
||
| `Empty` | 空态(插画 + 文案 + CTA) | ✅ `./Empty` |
|

| `A11y` 工具集 | useA11yId / mergeA11yProps / describeInput / focus-trap / skip-link / visually-hidden / aria-status | 迁移指南 §7.7 |
|
||
| `Form` | react-hook-form + zodResolver 封装 | 新建 |
|
||
| `RichTextEditor` | Tiptap 封装(备课/出题/反馈) | 新建 |

||
|
||
## 8. 共享 Hooks(packages/hooks/,ai13 维护,ARB-002 暴露)
|
||
|
||
| Hook | 职责 | MF 暴露(ARB-002) |
|
||
| --------------------- | --------------------------------------------------- | ------------------ |
|
||
| `useGraphQLClient()` | urql client 单例(Shell 注入,Remote 复用) | ✅ `./useGraphQLClient` |
|
||
| `useAuth()` | 会话状态(user/token/refresh/login/logout) | ✅ `./useAuth` |
|
||
| `usePermission()` | 权限查询(hasPermission/hasAny/hasAll + dataScope) | ✅ `./usePermission` |
|
||
| `useViewports(scope)` | 视口列表(GraphQL viewports Query,按 scope 过滤) | — |

|
||
| `useAriaLive()` | aria-live 区域管理 | — |
|
||
| `useToast()` | 全局 toast(Zustand ui-store) | — |
|
||
|
||
## 9. 设计令牌三层(packages/ui-tokens/,ai13 维护)
|
||
|
||
```
|
||
packages/ui-tokens/
|
||
├─ primitive.css # Layer 1 原始色板/字号/间距/阴影
|
||
├─ semantic-light.css # Layer 2 语义令牌(亮色)
|
||
├─ semantic-dark.css # Layer 2 语义令牌(暗色)
|
||
├─ tailwind-theme.css # Layer 3 @theme inline 暴露 bg-*/text-*/font-*
|
||
└─ package.json
|
||
```
|
||
|
||
**强制规则**(project_rules §3.10):
|
||
|
||
- 禁止 `#hex` 字面量(ESLint `no-restricted-syntax`)
|
||
- 禁止 `'Inter'`/`'Fraunces'`/`'JetBrains Mono'` 字面量(ESLint `design-tokens/no-hardcoded-fonts`)
|
||
- 禁止 `font-size: Npx`(用 `var(--font-size-1~9)`)
|
||
- 禁止 Tailwind 任意值 `w-[Npx]`(用 `--space-*` 或默认阶梯)
|
||
|
||
**令牌命名**(迁移指南 §7.1):
|
||
|
||
| Layer 1 Primitive | Layer 2 Semantic | Layer 3 Tailwind |
|
||
| ------------------ | ------------------ | ---------------- |
|
||
| `--color-blue-500` | `--color-accent` | `bg-accent` |
|
||
| `--font-size-3` | `--font-size-body` | `text-body` |
|
||
| `--space-4` | `--space-md` | `p-md` |
|
||
|
||
## 10. 与其他模块的交互点(契约清单)
|
||
|
||
| 方向 | 对方服务 | 协议 | 接口/事件 | 用途 | 阶段 |
|
||
| ------ | ------------ | ------------------ | --------------------------------------------------- | ---------------------------- | ---- |
|
||
| 调用 | api-gateway | HTTP(GraphQL over HTTP) | `/api/v1/teacher/*` 代理到 teacher-bff `POST /graphql` | 全部 GraphQL 业务请求 | P2+ |
|
||
| 调用 | api-gateway | HTTP | `POST /api/auth/login` | 教师登录(非 MF,认证前提) | P2 |
|
||
| 调用 | push-gateway | WebSocket | `ws://push-gateway:8081/ws` | 实时推送 | P5 |
|
||
| 调用 | ai | SSE | `GET /api/v1/ai/generate-questions` | AI 流式出题(非 GraphQL) | P5 |
|
||
| 被调用 | — | — | — | 前端不暴露接口给其他服务 | — |
|
||
| 消费 | teacher-bff | GraphQL(ARB-001 schema) | `dashboard`/`viewports`/`me`/`classes`/`class` Query(P2)+ P3+ Mutation | 教师场景聚合 | P2+ |
|
||
| 消费 | push-gateway | WebSocket | `NotificationRequested`/`HomeworkSubmitted`/角色变更 | 实时推送 | P5+ |
|
||
| 依赖 | coord 维护 | — | `packages/shared-proto` | TS 类型(仅 contracts 部分) | P1+ |
|
||
| 依赖 | coord 维护 | — | `packages/shared-ts` + `contracts/graphql/teacher-bff.graphql` | ApiClient/Logger/GraphQL schema/通用工具 | P2+ |
|
||
| 依赖 | ai13 维护 | — | `packages/ui-tokens`(已建,批次 0.15) | 三层设计令牌 | P2+ |
|
||
| 依赖 | ai13 维护 | — | `packages/ui-components`(已建,批次 0.15) | shadcn + 共享组件(ARB-002 暴露) | P2+ |
|
||
| 依赖 | ai13 维护 | — | `packages/hooks`(已建,批次 0.15) | useGraphQLClient/usePermission/useAuth(ARB-002 暴露) | P2+ |
|
||
| 依赖 | coord 维护 | — | `packages/contracts` | Permissions 常量 + 类型 | P2+ |
|
||
|
||
> **前端不直接调 gRPC**:teacher-bff 把 gRPC 聚合为 GraphQL 暴露给前端(F9 裁决)。前端仅消费 `packages/contracts/src/permissions.ts` 中的权限点常量(TS 文件,非 proto 生成)。
|
||
|
||
## 11. 风险与假设
|
||
|
||
### 11.1 假设
|
||
|
||
1. **假设 coord 建立 `packages/shared-ts`、`packages/contracts`**:包含 GraphQL schema、Logger、Permissions 常量、通用类型。✅ packages 骨架(ui-tokens/ui-components/hooks)已于批次 0.15 建立(ISSUE-039)。
|
||
2. **假设 teacher-bff 提供 `POST /graphql`(ARB-001 schema 第一版)**:返回 dashboard/viewports/me/classes/class 5 个 Query。⏳ 待 ai03 + coord 仲裁。
|
||
3. **假设 api-gateway 代理 `/api/v1/teacher/*` → teacher-bff:3003**:⏳ 待 ai01。
|
||
4. **假设 Next.js 14+ Module Federation 2.0 稳定**:`@module-federation/nextjs-mf` 在 Next.js App Router 下可用。若不稳定,降级为 4 端独立部署 + 各自 Shell(重复实现 AppShell)。
|
||
5. **假设 iam 提供 refresh cookie 端点**:P6 localStorage→httpOnly cookie 迁移前置。⏳ 待 ai06 P6。
|
||
|
||
### 11.2 技术风险
|
||
|
||
| 风险 | 影响 | 缓解 |
|
||
| ------------------------ | ----------------------------------------------------------- | ---------------------------------------------------------------------------------- |
|
||
| MF SSR 对齐复杂 | Remote 在 SSR 时需 Shell 提供上下文 | 优先 CSR,SSR 仅用于首屏 dashboard;MF 2.0 支持 SSR |
|
||
| 共享依赖版本漂移 | Remote 与 Shell 的 react/react-dom/urql/graphql 版本不一致导致运行时错误 | MF `shared.singleton: true`(ARB-002)+ CI 检查版本对齐 |
|
||
| Token 刷新竞态 | 多请求同时 401 触发多次 refresh | useAuth 全局单例 + refresh promise 复用(03 §2.7) |
|
||
| 权限缓存陈旧 | 角色变更后前端仍用旧权限 | iam 角色变更发 Kafka → msg → push-gateway WebSocket → urql cache invalidate |
|
||
| GraphQL schema 演进阻塞 | ai03 schema 变更未同步 ai13 导致前端 query 失效 | SDL-first + schema 注册表 `packages/shared-ts/contracts/graphql/`(ARB-001) |
|
||
| 设计令牌迁移破坏现有样式 | teacher-portal 现有硬编码令牌迁移到三层模型后样式漂移 | 灰度迁移:先建 ui-tokens 包,teacher-portal 引入但不删除旧 globals.css,验证后切换 |
|
||
| urql cache 膨胀 | 长时间使用后缓存项过多 | staleTime 分级 + P3 评估 graphcache normalized cache |
|
||
|
||
### 11.3 已决策设计点(原未决决策,现已对齐仲裁)
|
||
|
||
| 决策点 | 结论 | 裁决依据 |
|
||
| ------------------- | ----------------------------------------------------------- | ------------------------------- |
|
||
| packages 归属 | ai13 维护 ui-tokens/ui-components/hooks;coord 维护 shared-ts/contracts | 总裁 §2.18(ISSUE-039) |
|
||
| GraphQL vs REST | **P2 起 all-in GraphQL(urql),无 REST 过渡** | F9 + ARB-001(ISSUE-036/037) |
|
||
| i18n key 命名 | `error.{{service}}.{{code_snake_case}}`,与错误码前缀对齐 | F11 |
|
||
| MF 暴露粒度 | 暴露 AppShell 整体 + GraphQLProvider + hooks + UI 组件(ARB-002 清单) | 总裁 §2.17 + ARB-002(ISSUE-038) |
|
||
| GraphQL client 单例 | Shell 暴露 GraphQLProvider,Remote 复用(方案 A) | 总裁 §2.17(ISSUE-038) |
|
||
| P2 Remote 数量 | 0(NEXT_PUBLIC_MF_ENABLED=false),P3 student 首个接入 | ARB-002 §2.3 |
|
||
|
||
## 12. coord 交叉审查所需信息
|
||
|
||
### 12.1 端口矩阵
|
||
|
||
| 端 | dev 端口 | 生产端口 | 备注 |
|
||
| -------------- | -------- | -------- | ---------- |
|
||
| teacher-portal | 4000 | 4000 | Shell 宿主 |
|
||
|
||
> 与 [matrix.md](../../../docs/architecture/issues/matrix.md) §1 端口矩阵对齐(teacher-portal :4000)。
|
||
|
||
### 12.2 依赖的共享包
|
||
|
||
| 包 | 路径 | 维护方 | 内容 |
|
||
| --------------- | ------------------------- | ------------ | ------------------------------------------------- |
|
||
| `shared-ts` | `packages/shared-ts/` | coord | ApiClient、Logger、GraphQL schema、通用工具 |
|
||
| `contracts` | `packages/contracts/` | coord | Permissions 常量、ActionState 类型、UserInfo 类型 |
|
||
| `ui-tokens` | `packages/ui-tokens/` | ai13 | 三层设计令牌(✅ 已建,批次 0.15) |
|
||
| `ui-components` | `packages/ui-components/` | ai13 | shadcn + ErrorBoundary + RequirePermission(✅ 已建,ARB-002 暴露) |
|
||
| `hooks` | `packages/hooks/` | ai13 | useGraphQLClient/usePermission/useAuth(✅ 已建,ARB-002 暴露) |
|
||
|
||
### 12.3 依赖的后端契约(需对应 AI 确认)
|
||
|
||
| 契约 | 提供方 | 当前状态 |
|
||
| ------------------------------------------------------------------ | ------------------ | ------------------- |
|
||
| `POST /graphql` + dashboard/viewports/me/classes/class Query(ARB-001) | teacher-bff(ai03)| ⏳ 待 coord 仲裁 |
|
||
| `POST /api/auth/login` | api-gateway(ai01)→ iam | ⏳ 待 ai01 |
|
||
| classExams/classHomework/studentGrades Query + Mutation | teacher-bff(ai03 P3)| ⏳ 待 ai03 P3 |
|
||
| knowledgeGraph/studentAnalytics Query | teacher-bff(ai03 P4)| ⏳ 待 ai03 P4 |
|
||
| myNotifications/markAsRead Query + Mutation | teacher-bff(ai03 P5)| ⏳ 待 ai03 P5 |
|
||
| `ws://push-gateway:8081/ws` 推送 | push-gateway(ai02 P5)| ⏳ 待 ai02 P5 |
|
||
| `GET /api/v1/ai/generate-questions`(SSE) | ai(ai12 P5) | ⏳ 待 ai12 P5 |
|
||
|
||
### 12.4 错误码前缀(前端 i18n 路由依赖,对齐 [matrix.md §6](../../../docs/architecture/issues/matrix.md))
|
||
|
||
前端不产生错误码,仅消费。需各服务确认错误码前缀不重叠:
|
||
|
||
| 前缀 | 服务 | 状态 |
|
||
| ------------------------------ | ----------- | --------- |
|
||
| `IAM_` | iam | ✅ 已用 |
|
||
| `CORE_EDU_` | core-edu | ✅ 已用 |
|
||
| `CLASSES_` | core-edu | ✅ 已用 |
|
||
| `EXAMS_`/`HOMEWORK_`/`GRADES_` | core-edu | ⚠️ 待确认 |
|
||
| `CONTENT_` | content | ⚠️ 待确认 |
|
||
| `MSG_` | msg | ⚠️ 待确认 |
|
||
| `AI_` | ai | ⚠️ 待确认 |
|
||
| `BFF_TEACHER_` | teacher-bff | ✅ 已裁决(G14) |
|
||
| `GW_` | api-gateway | ✅ 已用 |
|
||
| `NETWORK_` | 前端 | ai13 自有 |
|
||
|
||
### 12.5 不产生 Kafka 事件
|
||
|
||
前端不发布/消费 Kafka 事件。WebSocket 推送由 push-gateway 消费 Kafka 转发。
|
||
|
||
## 13. 实施路线(ai13 自用,详见 [workline.md](../../../docs/architecture/issues/worklines/teacher-portal_workline.md))

||
3. 多 Tab 会话同步(BroadcastChannel,03 §2.5)
|
||
|
||
### P5(推送 + AI 接入)
