## Prerequisites
|
||||
|
||||
- **Go 1.24+**
|
||||
- **PostgreSQL 15+** with `ltree` extension support
|
||||
- **Redis 7+**
|
||||
- **MinIO** (or S3-compatible object storage)
|
||||

|
||||
|
||||
## Configuration
|
||||
|
||||
### Config File
|
||||
|
||||
Configuration is loaded from `config.toml` (gitignored), generated from `config.toml.tmpl` by `deploy/script/prepare.sh`.
|
||||
|
||||
**Generation:**
|
||||
```bash
|
||||
# From repo root
|
||||
bash deploy/script/prepare.sh
|
||||
```
|
||||
|
||||
**Format:** TOML with environment variable substitution (`${ENV_VAR}`).
|
||||
|
||||
**Environment variables:** Defined in `deploy/.env` (template: `deploy/.env.example`).
|
||||
|
||||
**Access:** Via `config.GlobalConfig.*` singleton.
|
||||
|
||||
### Key Configuration Sections

|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
### 1. Start Infrastructure
|
||||
|
||||
From the repository root:
|
||||
|
||||
```bash
|
||||
# Generate config files
|
||||
bash deploy/script/configure.sh # Interactive setup
|
||||
# OR
|
||||
cp deploy/.env.example deploy/.env
|
||||
bash deploy/script/prepare.sh # Non-interactive
|
||||
|
||||
# Start all services via Docker Compose
|
||||
bash deploy/script/start.sh dev up
|
||||
```
|
||||
|
||||
This starts:
|
||||
- PostgreSQL, Redis, Consul, MinIO, RabbitMQ, Elasticsearch
|
||||
- Backend API server (with automatic migration + seeding)
|
||||
- Background workers (snapshot, notification, search-sync)
|
||||
- Frontend, collaboration services, nginx
|
||||
|
||||
### 2. Run Backend Standalone (Optional)
|
||||
|
||||
If infrastructure is already running externally:
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
|
||||
# Run migration + seeding
|
||||
go run ./cmd/migrate
|
||||
go run ./cmd/db_init
|
||||
go run ./cmd/es_init
|
||||
|
||||
# Start API server
|
||||
go run ./cmd/main.go
|
||||
```
|
||||
|
||||
### 3. Verify
|
||||
|
||||
Health endpoints:
|
||||
- `GET /health` — Liveness check
|
||||
- `GET /readyz` — Readiness (checks DB + Redis)
|
||||
- `GET /livez` — Liveness alias
|
||||
|
||||
## API Structure
|
||||
|
||||
### Connect RPC
|
||||
|
||||
The backend exposes two HTTP listeners using Connect RPC (not raw gRPC):
|
||||
|
||||
| Port | Purpose | Protocol |
|
||||
|------|---------|----------|
|
||||
| 9090 | Native gRPC | HTTP/2 |
|
||||
| 8080 | gRPC-web | HTTP/1.1+ (browser clients) |
|
||||
|
||||
Both listeners use h2c (HTTP/2 cleartext).
|
||||
|
||||
### Services
|
||||
|
||||
The API is organized into the following services:
|
||||
|
||||
- **AuthService**: Login, register, profile management
|
||||
- **DocumentService**: Document CRUD, versioning, attachments, templates
|
||||
- **KnowledgeBaseService**: Knowledge base management
|
||||
- **MembershipService**: User groups, org structure, memberships
|
||||
- **InvitationService**: Invitation creation and management
|
||||
- **NotificationService**: Notification CRUD, read status
|
||||
- **CommentService**: Document comments
|
||||
- **SettingService**: System settings
|
||||
- **SystemService**: Health checks, system info
|
||||
|
||||
### Authentication
|
||||
|
||||
JWT-based authentication with the following unauthenticated endpoints:
|
||||
- `AuthService.Login`
|
||||
- `AuthService.Register`
|
||||
- `SystemService.Health`
|
||||
- `SystemService.SystemInfo`
|
||||
|
||||
All other endpoints require a valid JWT in the `Authorization: Bearer <token>` header.
|
||||
|
||||
## Background Workers
|
||||
|
||||
### Snapshot Worker
|
||||
|
||||
**Purpose:** Persist Yjs document snapshots to the database.
|
||||
|
||||
**Queue:** Consumes from RabbitMQ topic for dirty document notifications.
|
||||
|
||||
**Flow:**
|
||||
1. Collab service marks document as dirty after edits
|
||||
2. Snapshot worker receives notification
|
||||
3. Fetches current Yjs state from collab service
|
||||
4. Persists snapshot to `document_yjs_snapshots` table
|
||||
|
||||
### Notification Worker
|
||||
|
||||
**Purpose:** Process and deliver notifications.
|
||||
|
||||
**Queue:** Consumes from RabbitMQ notification topics.
|
||||
|
||||
### Search Sync Worker
|
||||
|
||||
**Purpose:** Keep Elasticsearch index in sync with database.
|
||||
|
||||
**Queue:** Consumes from RabbitMQ for document/KB changes.
|
||||
|
||||
**Flow:**
|
||||
1. Document/KB created/updated/deleted
|
||||
2. Worker receives event
|
||||
3. Updates Elasticsearch index accordingly
|
||||
|
||||
## Database
|
||||
|
||||
### Schema Management
|
||||
|
||||
**Migration:** GORM `AutoMigrate` based on model struct definitions.
|
||||
|
||||
**Location:** `cmd/migrate/migration.go`
|
||||
|
||||
**Process:**
|
||||
1. Creates PostgreSQL `ltree` extension (for hierarchical org structure)
|
||||
2. Auto-migrates all 16 models
|
||||
3. Creates custom indexes (unique constraints on recent items)
|
||||
4. Applies manual migrations (e.g., dropping deprecated columns)
|
||||
|
||||
**Models:**
|
||||
- User
|
||||
- Document, DocumentVersion, DocumentYjsSnapshot, DocumentComment
|
||||
- KnowledgeBase
|
||||
- Template
|
||||
- Attachment
|
||||
- Invitation, InvitationRecord
|
||||
- Notification
|
||||
- UserGroupMeta, MembershipRelation
|
||||
- OrgNodeMeta
|
||||
- RecentDocument, RecentKnowledgeBase, RecentTemplate
|
||||
|
||||
### Seeding
|
||||
|
||||
**Location:** `cmd/db_init/`
|
||||
|
||||
**Process:**
|
||||
1. Creates admin user (username: `admin`, password from config)
|
||||
2. Creates default permissions
|
||||
3. Creates default user groups
|
||||
4. Creates default templates
|
||||
|
||||
## Development
|
||||
|
||||
### Code Structure Patterns
|
||||
|
||||
**Service Layer:**
|
||||
```go
|
||||
// Package-level singleton
|
||||
var AuthSvc *AuthService
|
||||
|
||||
// Initialization in service.Init()
|
||||
func Init(cfg *config.Config, repos *repository.Repositories) error {
|
||||
auth_service.AuthSvc = auth_service.NewAuthService(repos)
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**Repository Layer:**
|
||||
```go
|
||||
// Constructed via Repositories struct
|
||||
type Repositories struct {
|
||||
DB *gorm.DB
|
||||
Redis *redis.Client
|
||||
Document *document_repo.DocumentRepository
|
||||
// ...
|
||||
}
|
||||
|
||||
func NewRepositories(db *gorm.DB, redis *redis.Client) *Repositories {
|
||||
return &Repositories{
|
||||
Document: document_repo.NewDocumentRepository(db, redis),
|
||||
// ...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Error Handling:**
|
||||
```go
|
||||
// Typed errors with status codes
|
||||
return status.GenErrWithCustomMsg(
|
||||
status.StatusServiceInternalError,
|
||||
"operation failed",
|
||||
)
|
||||
```
|
||||
|
||||
### Protobuf Codegen
|
||||
|
||||
**Source:** `proto/yoresee_doc/v1/yoresee_doc.proto`
|
||||
|
||||
**Generated Go code:** `pkg/gen/` (gitignored)
|
||||
|
||||
**Regenerate:**
|
||||
```bash
|
||||
# From repo root
|
||||
bash deploy/script/gen_proto.sh
|
||||
```
|
||||
|
||||
**Targets:**
|
||||
- `backend/pkg/gen` — Go stubs
|
||||
- `collab-go/pkg/gen` — Go stubs
|
||||
- `frontend/src/gen` — TypeScript ES modules
|
||||
- `collab/src/gen` — Node gRPC stubs
|
||||
|
||||
### Verification
|
||||
|
||||
No linter or test suite configured. Verify changes with:
|
||||
|
||||
```bash
|
||||
go build ./...
|
||||
go vet ./...
|
||||
```
|
||||
|
||||
## Deployment
|
||||
|
||||
### Docker Images
|
||||
|
||||
| Dockerfile | Purpose |
|
||||
|------------|---------|
|
||||
| `Dockerfile` | Dev image (with Delve debugger) |
|
||||
| `Dockerfile.prod` | Production API server |
|
||||
| `Dockerfile.snapshot.prod` | Production snapshot worker |
|
||||
| `Dockerfile.notification.prod` | Production notification worker |
|
||||
| `Dockerfile.search-sync.prod` | Production search-sync worker |
|
||||
|
||||
### Startup Sequence
|
||||
|
||||
Container CMD for production:
|
||||
```bash
|
||||
./migrate.out && ./db_init.out && ./es_init.out && ./main.out
|
||||
```
|
||||
|
||||
Workers are separate containers with their own entrypoints.
|
||||
|
||||
### Health Checks
|
||||
|
||||
Docker Compose uses `wget` to check `/health` endpoint:
|
||||
```yaml
|
||||
healthcheck:
|
||||
test: ["CMD", "wget", "--spider", "-q", "http://backend:9090/health"]
|
||||
interval: 5s
|
||||
timeout: 3s
|
||||
retries: 20
|
||||
start_period: 30s
|
||||
```
|
||||
|
||||

## 前置要求
|
||||
|
||||
- **Go 1.24+**
|
||||
- **PostgreSQL 15+** 支持 `ltree` 扩展
|
||||
- **Redis 7+**
|
||||
- **MinIO** (或 S3 兼容对象存储)
|
||||

|
||||
|
||||
## 配置
|
||||
|
||||
### 配置文件
|
||||
|
||||
配置从 `config.toml` (gitignored) 加载，由 `deploy/script/prepare.sh` 从 `config.toml.tmpl` 生成。
|
||||
|
||||
**生成：**
|
||||
```bash
|
||||
# 在仓库根目录
|
||||
bash deploy/script/prepare.sh
|
||||
```
|
||||
|
||||
**格式：** TOML，支持环境变量替换 (`${ENV_VAR}`)。
|
||||
|
||||
**环境变量：** 在 `deploy/.env` 中定义 (模板：`deploy/.env.example`)。
|
||||
|
||||
**访问方式：** 通过 `config.GlobalConfig.*` 单例。
|
||||
|
||||
### 关键配置部分
|
||||
|
||||

|
||||
|
||||
[mq_config.rabbitmq]
|
||||
url = "amqp://guest:guest@localhost:5672/"
|
||||
|
||||
[backend]
|
||||
system_name = "yoresee_doc"
|

||||
password_hash_cost = 12
|
||||
max_login_attempts = 5
|
||||

|
||||
```
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 1. 启动基础设施
|
||||
|
||||
在仓库根目录：
|
||||
|
||||
```bash
|
||||
# 生成配置文件
|
||||
bash deploy/script/configure.sh # 交互式设置
|
||||
# 或
|
||||
cp deploy/.env.example deploy/.env
|
||||
bash deploy/script/prepare.sh # 非交互式
|
||||
|
||||
# 通过 Docker Compose 启动所有服务
|
||||
bash deploy/script/start.sh dev up
|
||||
```
|
||||
|
||||
这将启动：
|
||||
- PostgreSQL、Redis、Consul、MinIO、RabbitMQ、Elasticsearch
|
||||
- 后端 API 服务器 (自动迁移 + 种子数据)
|
||||
- 后台工作器 (快照、通知、搜索同步)
|
||||
- 前端、协作服务、nginx
|
||||
|
||||
### 2. 独立运行后端 (可选)
|
||||
|
||||
如果基础设施已在外部运行：
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
|
||||
# 运行迁移 + 种子数据
|
||||
go run ./cmd/migrate
|
||||
go run ./cmd/db_init
|
||||
go run ./cmd/es_init
|
||||
|
||||
# 启动 API 服务器
|
||||
go run ./cmd/main.go
|
||||
```
|
||||
|
||||
### 3. 验证
|
||||
|
||||
健康检查端点：
|
||||
- `GET /health` — 存活检查
|
||||
- `GET /readyz` — 就绪检查 (检查 DB + Redis)
|
||||
- `GET /livez` — 存活检查别名
|
||||
|
||||
## API 结构
|
||||
|
||||
### Connect RPC
|
||||
|
||||
后端使用 Connect RPC (非原生 gRPC) 暴露两个 HTTP 监听器：
|
||||
|
||||
| 端口 | 用途 | 协议 |
|
||||
|------|------|------|
|
||||
| 9090 | 原生 gRPC | HTTP/2 |
|
||||
| 8080 | gRPC-web | HTTP/1.1+ (浏览器客户端) |
|
||||
|
||||
两个监听器都使用 h2c (HTTP/2 明文)。
|
||||
|
||||
### 服务
|
||||
|
||||
API 组织为以下服务：
|
||||
|
||||
- **AuthService**：登录、注册、个人资料管理
|
||||
- **DocumentService**：文档 CRUD、版本控制、附件、模板
|
||||
- **KnowledgeBaseService**：知识库管理
|
||||
- **MembershipService**：用户组、组织结构、成员关系
|
||||
- **InvitationService**：邀请创建和管理
|
||||
- **NotificationService**：通知 CRUD、已读状态
|
||||
- **CommentService**：文档评论
|
||||
- **SettingService**：系统设置
|
||||
- **SystemService**：健康检查、系统信息
|
||||
|
||||
### 认证
|
||||
|
||||
基于 JWT 的认证，以下端点无需认证：
|
||||
- `AuthService.Login`
|
||||
- `AuthService.Register`
|
||||
- `SystemService.Health`
|
||||
- `SystemService.SystemInfo`
|
||||
|
||||
所有其他端点需要在 `Authorization: Bearer <token>` 头中提供有效的 JWT。
|
||||
|
||||
## 后台工作器
|
||||
|
||||
### 快照工作器
|
||||
|
||||
**用途：** 将 Yjs 文档快照持久化到数据库。
|
||||
|
||||
**队列：** 消费 RabbitMQ 主题中的脏文档通知。
|
||||
|
||||
**流程：**
|
||||
1. 协作服务在编辑后将文档标记为脏
|
||||
2. 快照工作器接收通知
|
||||
3. 从协作服务获取当前 Yjs 状态
|
||||
4. 将快照持久化到 `document_yjs_snapshots` 表
|
||||
|
||||
### 通知工作器
|
||||
|
||||
**用途：** 处理和投递通知。
|
||||
|
||||
**队列：** 消费 RabbitMQ 通知主题。
|
||||
|
||||
### 搜索同步工作器
|
||||
|
||||
**用途：** 保持 Elasticsearch 索引与数据库同步。
|
||||
|
||||
**队列：** 消费 RabbitMQ 中的文档/知识库变更。
|
||||
|
||||
**流程：**
|
||||
1. 文档/知识库被创建/更新/删除
|
||||
2. 工作器接收事件
|
||||
3. 相应更新 Elasticsearch 索引
|
||||
|
||||
## 数据库
|
||||
|
||||
### 模式管理
|
||||
|
||||
**迁移：** 基于模型结构体定义的 GORM `AutoMigrate`。
|
||||
|
||||
**位置：** `cmd/migrate/migration.go`
|
||||
|
||||
**流程：**
|
||||
1. 创建 PostgreSQL `ltree` 扩展 (用于层级组织结构)
|
||||
2. 自动迁移所有 16 个模型
|
||||
3. 创建自定义索引 (最近访问项的唯一约束)
|
||||
4. 应用手动迁移 (例如，删除已弃用的列)
|
||||
|
||||
**模型：**
|
||||
- User (用户)
|
||||
- Document, DocumentVersion, DocumentYjsSnapshot, DocumentComment (文档相关)
|
||||
- KnowledgeBase (知识库)
|
||||
- Template (模板)
|
||||
- Attachment (附件)
|
||||
- Invitation, InvitationRecord (邀请相关)
|
||||
- Notification (通知)
|
||||
- UserGroupMeta, MembershipRelation (用户组和成员关系)
|
||||
- OrgNodeMeta (组织节点)
|
||||
- RecentDocument, RecentKnowledgeBase, RecentTemplate (最近访问)
|
||||
|
||||
### 种子数据
|
||||
|
||||
**位置：** `cmd/db_init/`
|
||||
|
||||
**流程：**
|
||||
1. 创建管理员用户 (用户名：`admin`，密码来自配置)
|
||||
2. 创建默认权限
|
||||
3. 创建默认用户组
|
||||
4. 创建默认模板
|
||||
|
||||
## 开发
|
||||
|
||||
### 代码结构模式
|
||||
|
||||
**服务层：**
|
||||
```go
|
||||
// 包级单例
|
||||
var AuthSvc *AuthService
|
||||
|
||||
// 在 service.Init() 中初始化
|
||||
func Init(cfg *config.Config, repos *repository.Repositories) error {
|
||||
auth_service.AuthSvc = auth_service.NewAuthService(repos)
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
**仓储层：**
|
||||
```go
|
||||
// 通过 Repositories 结构体构造
|
||||
type Repositories struct {
|
||||
DB *gorm.DB
|
||||
Redis *redis.Client
|
||||
Document *document_repo.DocumentRepository
|
||||
// ...
|
||||
}
|
||||
|
||||
func NewRepositories(db *gorm.DB, redis *redis.Client) *Repositories {
|
||||
return &Repositories{
|
||||
Document: document_repo.NewDocumentRepository(db, redis),
|
||||
// ...
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**错误处理：**
|
||||
```go
|
||||
// 带状态码的类型化错误
|
||||
return status.GenErrWithCustomMsg(
|
||||
status.StatusServiceInternalError,
|
||||
"operation failed",
|
||||
)
|
||||
```
|
||||
|
||||
### Protobuf 代码生成
|
||||
|
||||
**源文件：** `proto/yoresee_doc/v1/yoresee_doc.proto`
|
||||
|
||||
**生成的 Go 代码：** `pkg/gen/` (gitignored)
|
||||
|
||||
**重新生成：**
|
||||
```bash
|
||||
# 在仓库根目录
|
||||
bash deploy/script/gen_proto.sh
|
||||
```
|
||||
|
||||
**目标：**
|
||||
- `backend/pkg/gen` — Go 代码
|
||||
- `collab-go/pkg/gen` — Go 代码
|
||||
- `frontend/src/gen` — TypeScript ES 模块
|
||||
- `collab/src/gen` — Node gRPC 代码
|
||||
|
||||
### 代码验证
|
||||
|
||||
未配置 linter 或测试套件。使用以下命令验证更改：
|
||||
|
||||
```bash
|
||||
go build ./...
|
||||
go vet ./...
|
||||
```
|
||||
|
||||
## 部署
|
||||
|
||||
### Docker 镜像
|
||||
|
||||
| Dockerfile | 用途 |
|
||||
|------------|------|
|
||||
| `Dockerfile` | 开发镜像 (含 Delve 调试器) |
|
||||
| `Dockerfile.prod` | 生产 API 服务器 |
|
||||
| `Dockerfile.snapshot.prod` | 生产快照工作器 |
|
||||
| `Dockerfile.notification.prod` | 生产通知工作器 |

### 启动顺序
|
||||
|
||||
生产环境容器 CMD：
|
||||
```bash
|
||||
./migrate.out && ./db_init.out && ./es_init.out && ./main.out
|
||||
```
|
||||
|
||||
工作器是独立的容器，有自己的入口点。
|
||||
|
||||
### 健康检查
|
||||
|
||||
Docker Compose 使用 `wget` 检查 `/health` 端点：
|
||||
```yaml
|
||||
healthcheck:
|
||||
test: ["CMD", "wget", "--spider", "-q", "http://backend:9090/health"]
|
||||
interval: 5s
|
||||
timeout: 3s
|
