go.echo.missing_middleware

Stability Medium

Detects Echo apps without essential middleware.

Why It Matters

Missing middleware:

• No error handling — Unhandled panics crash server
• No request logging — Can’t debug issues
• No request timeout — Slow requests block server

Example

// ❌ Before (no middleware)
e := echo.New()
e.GET("/", handler)

// ✅ After (with essential middleware)
e := echo.New()
e.Use(middleware.Logger())
e.Use(middleware.Recover())
e.Use(middleware.TimeoutWithConfig(middleware.TimeoutConfig{
    Timeout: 30 * time.Second,
}))
e.GET("/", handler)
