# Architecture
|
|
|
|
## Layered Design
|
|
|
|
```
|
|
Handler (Gin handlers) ← translates HTTP ↔ Service calls
|
|
↓
|
|
Service (business logic) ← orchestrates, authorizes, validates
|
|
↓ ↓
|
|
Repository (GORM data access) Storage (file I/O)
|
|
↓ ↓
|
|
[SQLite / PostgreSQL] [Local FS / S3]
|
|
```
|
|
|
|
Rules:
|
|
- Handler has no business logic — parse request, call service, write response.
|
|
- Service has no HTTP awareness — operates on domain models and interfaces.
|
|
- Repository abstracts the database; Storage abstracts where bytes live.
|
|
- `internal/server` is the composition root — wires all dependencies together.
|
|
|
|
## Package Map
|
|
|
|
| Layer | Package | Purpose | Status |
|
|
|-------|---------|---------|--------|
|
|
| **CLI** | `cmd` | Cobra root command | ✅ skeleton |
|
|
| | `cmd/serve.go` | `mygo serve` — wire deps, start HTTP | ⬜ plan |
|
|
| | `cmd/config.go` | `mygo config` — config subcommand | ⬜ plan |
|
|
| | `cmd/status.go` | `mygo status` — health check | ⬜ plan |
|
|
| **Config** | `internal/config` | Viper load (YAML + env + flags) | ⬜ plan |
|
|
| **HTTP** | `internal/server` | Gin engine init, route registration, middleware chain | ⬜ plan |
|
|
| | `internal/handler` | HTTP handlers (auth, file, admin, webdav...) | ⬜ plan |
|
|
| | `internal/middleware` | Gin middleware (requestid, logger, cors, auth) | ⬜ plan |
|
|
| **Business** | `internal/service` | Business logic (auth, file, admin) | ⬜ plan |
|
|
| | `internal/model` | Domain types (User, File, errors) | ⬜ plan |
|
|
| **Data** | `internal/repository` | Repository interfaces + GORM implementations | ⬜ plan |
|
|
| | `internal/storage` | Storage backend interface + local disk impl | ⬜ plan |
|
|
| **Util** | `internal/auth` | JWT sign/verify, context helpers | ⬜ plan |
|
|
| | `internal/api` | JSON response writer, error code helpers | ⬜ plan |
|
|
|
|
## API Routes (v0)
|
|
|
|
```
|
|
POST /api/v1/auth/register
|
|
POST /api/v1/auth/login
|
|
POST /api/v1/auth/refresh
|
|
|
|
GET /api/v1/users/me
|
|
PATCH /api/v1/users/me
|
|
|
|
GET /api/v1/files
|
|
POST /api/v1/files
|
|
GET /api/v1/files/:id
|
|
GET /api/v1/files/:id/content
|
|
PUT /api/v1/files/:id
|
|
DELETE /api/v1/files/:id
|
|
|
|
GET /api/v1/admin/users
|
|
GET /api/v1/admin/users/:id
|
|
PUT /api/v1/admin/users/:id
|
|
DELETE /api/v1/admin/users/:id
|
|
```
|
|
|
|
## Middleware Chain
|
|
|
|
Applied globally: requestid → logger → cors
|
|
|
|
Applied to protected groups: auth (JWT validation, inject user into gin.Context)
|
