3219378872 Zero Powers REST API

go-zero REST API

Core Principles

Always Follow

• Three-layer separation: Handler (routing/validation) → Logic (business) → Model (data), never mix
• Context propagation: Pass ctx context.Context through all layers for tracing and cancellation
• Type safety: Define request/response types in .api files, generate with goctl
• Structured errors: Use httpx.Error(w, err) for HTTP error responses
• Middleware layering: Auth → Validation → Business logic

Never Do

• Put business logic in handlers
• Hard-code configuration values (use conf.MustLoad + ServiceContext)
• Mix layers (handler doing database calls)
• Discard errors with _

Common Workflows

New REST API Service

1. Define API spec in .api file
2. Generate: goctl api go -api xxx.api -dir .
3. Implement logic in internal/logic/
4. Details: rest-api-patterns.md

Add New Endpoint

1. Add handler, request, response types to .api
2. Regenerate handler/types with goctl
3. Implement logic in internal/logic/
4. Run checklist: new-handler-checklist.md

Add Middleware

1. Implement middleware in internal/middleware/
2. Register in service context
3. Run checklist: new-middleware-checklist.md
