1. Gin

Features

• A fast and efficient web framework.
• It provides a rich set of features such as routing, middleware, parameter binding, JSON/XML rendering, etc.

Sample Code

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")
}

This program simultaneously demonstrates examples of github.com/gin-gonic/gin, github.com/zeromicro/go-zero/rest, and other commonly used Go web frameworks. After running the program, you can visit http://localhost:8080/hello, http://localhost:8081/hello, and http://localhost:8888/hello to view the example return results of each framework respectively.

2. Echo

Features

• A lightweight, high-performance web framework.
• It has a concise API design.

Sample Code

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")
}

3. Gorilla Mux

Features

• It has powerful routing capabilities.
• It provides various components and tools.

Sample Code

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)
}

4. Beego

Features

• A full-featured MVC framework.
• It provides a wealth of built-in functions such as routing, middleware, ORM, etc.

Sample Code

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")
}

5. Revel

Features

• A high-productivity full-stack framework.
• It provides functions such as routing, controllers, and template engines.

Sample Code

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")
}

6. Fiber

Features

• A Go web framework similar to Express.js.
• It has high performance, flexibility, and a concise API design.

Sample Code

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")
}

7. go-zero/rest

Features

• A simple and easy-to-use RESTful API framework.
• Based on the Go - Zero framework, it is suitable for high-concurrency scenarios.

Sample Code

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!"))
}

These examples demonstrate how to use each framework to create a simple HTTP server and return the string "Hello, world!" when accessing the /hello path.
