mkdir my-api && cd my-api
go mod init my-api
go get github.com/labstack/echo/v4
package main

import (
    "net/http"
    "github.com/labstack/echo/v4"
    "github.com/labstack/echo/v4/middleware"
)

func main() {
    e := echo.New()
    e.Use(middleware.Logger())
    e.Use(middleware.Recover())
    e.Use(middleware.CORS())

    e.GET("/api/hello", func(c echo.Context) error {
        return c.JSON(http.StatusOK, map[string]string{"message": "Hello from Echo"})
    })

    e.Logger.Fatal(e.Start(":8080"))
}
介绍

Echo is a high performance, minimalist Go web framework with a clean and expressive API. Features automatic TLS via Let"s Encrypt, HTTP/2 support, extensible middleware, data binding and validation, and central error handling.

What Echo Does

  • Optimized router — radix tree, zero dynamic allocations
  • Middleware — Logger, Recover, CORS, JWT, BasicAuth, Rate Limiter, Gzip
  • Data binding — JSON, XML, form, query to structs
  • Validation — struct tag validation
  • Templates — any Go template engine
  • Auto TLS — Let"s Encrypt integration
  • HTTP/2 — native support
  • WebSocket — via gorilla/websocket
  • Group routing — shared prefix and middleware

Architecture

Radix tree router with zero allocation path matching. Context carries request/response and is reused via sync.Pool. Middleware chain executes via next(). Implements http.Handler for stdlib compatibility.

Comparison

Framework Router Key Strength
Echo Radix tree Best docs, auto TLS
Gin httprouter Largest community
Fiber Fasthttp Fastest raw speed
Chi stdlib Full stdlib compat

常见问题 FAQ

Q: Echo vs Gin？ A: 功能非常接近。Echo 文档更好、内置 auto TLS；Gin 社区更大、star 更多。两者性能几乎一样。
