Go Framework Comparison for Web Development

This article compares seven popular Go web frameworks: Gin, Echo, Gorilla Mux, Beego, Revel, Fiber, and go-zero/rest. Each is evaluated based on key features and suitability for various development needs. All examples below demonstrate a simple "Hello, World!" server.

1. Gin

• Key Features: Fast, efficient, rich feature set (routing, middleware, parameter binding, JSON/XML rendering).
• Example Code:

<code class="language-go">package main

import "github.com/gin-gonic/gin"

func main() {
    router := gin.Default()

    router.GET("/hello", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "message": "Hello, world!",
        })
    })

    router.Run(":8080")
}</code>

2. Echo

• Key Features: Lightweight, high-performance, concise API.
• Example Code:

<code class="language-go">package main

import (
    "net/http"

    "github.com/labstack/echo/v4"
)

func main() {
    e := echo.New()

    e.GET("/hello", func(c echo.Context) error {
        return c.String(http.StatusOK, "Hello, World!")
    })

    e.Start(":8080")
}</code>

3. Gorilla Mux

• Key Features: Powerful routing capabilities, various components and tools.
• Example Code:

<code class="language-go">package main

import (
    "fmt"
    "net/http"

    "github.com/gorilla/mux"
)

func main() {
    r := mux.NewRouter()

    r.HandleFunc("/hello", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(w, "Hello, world!")
    })

    http.ListenAndServe(":8080", r)
}</code>

4. Beego

• Key Features: Full-featured MVC framework, built-in functions (routing, middleware, ORM).
• Example Code:

<code class="language-go">package main

import (
    "github.com/astaxie/beego"
)

type MainController struct {
    beego.Controller
}

func (c *MainController) Get() {
    c.Ctx.WriteString("Hello, world!")
}

func main() {
    beego.Router("/hello", &MainController{})
    beego.Run(":8080")
}</code>

5. Revel

• Key Features: High-productivity full-stack framework, includes routing, controllers, and template engines.
• Example Code:

<code class="language-go">package main

import "github.com/revel/revel"

func Hello() revel.Result {
    return revel.Text("Hello, world!")
}

func main() {
    revel.Get("/hello", Hello)
    revel.Run(":8080")
}</code>

6. Fiber

• Key Features: Similar to Express.js, high-performance, flexible, concise API.
• Example Code:

<code class="language-go">package main

import "github.com/gofiber/fiber/v2"

func main() {
    app := fiber.New()

    app.Get("/hello", func(c *fiber.Ctx) error {
        return c.SendString("Hello, world!")
    })

    app.Listen(":8080")
}</code>

7. go-zero/rest

• Key Features: Simple, easy-to-use RESTful API framework, suitable for high-concurrency.
• Example Code:

<code class="language-go">package main

import (
    "net/http"

    "github.com/zeromicro/go-zero/rest"
)

func main() {
    engine := rest.NewEngine()
    defer engine.Stop()

    engine.AddRoute(rest.Route{
        Method:  http.MethodGet,
        Path:    "/hello",
        Handler: helloHandler,
    })

    engine.Start()
}

func helloHandler(w http.ResponseWriter, r *http.Request) {
    w.Write([]byte("Hello, world!"))
}</code>
