Echo

Echo is a minimalist Go framework known for performance. v4 is stable and widely used for microservices.

When to Use

• Microservices: Lightweight REST APIs.
• Performance: Low memory footprint.
• Simplicity: No magic, just handlers and middleware.

Core Concepts

Context

c.Param(), c.JSON(). The context object wraps request/response.

Middleware

Centralized logic. e.Use(middleware.Logger()).

Binding

c.Bind(u) binds JSON/Form data to structs.

Best Practices (2025)

Do:

• Use Validator: Integrate go-playground/validator for struct validation.
• Use Graceful Shutdown: Support safe deployment restarts.
• Group Routes: v1 := e.Group("/v1").

Don't:

• Don't ignore errors: Go requires explicit error handling.
