Skillshub golang-api-server

Standards for building HTTP services, REST APIs, and middleware in Golang. Use when building Go HTTP servers, REST APIs, or custom middleware. (triggers: cmd/server/*.go, internal/adapter/handler/**, http server, rest api, gin, echo, middleware)

Golang API Server Standards

Priority: P0 (CRITICAL)

Router Selection

Standard Lib (
net/http
): Use for simple services or when zero deps is required. Use
```
http.ServeMux
```
(Go 1.22+ has decent routing).
Echo (
labstack/echo
): Recommended for production REST APIs. Excellent middleware support, binding, and error handling.
Gin (
gin-gonic/gin
): High performance alternative.

Guidelines

Graceful Shutdown: MUST implement graceful shutdown to handle in-flight requests on termination (SIGINT/SIGTERM).
DTOs: Separate Domain structs from API Request/Response structs. Map between them.
Middleware: Use middleware for cross-cutting concerns (Logging, Recovery, CORS, Auth, Tracing).
Health Checks: Always include
```
/health
```
and
```
/ready
```
endpoints.
Content-Type: Enforce
```
application/json
```
for REST APIs.

Middleware Pattern

Standard:
```
func(next http.Handler) http.Handler
```

Echo implementation:

func(next echo.HandlerFunc) echo.HandlerFunc

Anti-Patterns

No business logic in handlers: Parse request → call service → format response only.
No global router vars: Pass router instance via constructor or DI.
No missing graceful shutdown: Always handle SIGTERM to drain in-flight requests.
