Title: Featured Recommendations: Five must-know common frameworks of Go language

As a fast and efficient programming language, Go language has gained more and more attention Developer favor. In the Go language ecosystem, there are many excellent frameworks that can help developers quickly build applications and improve development efficiency. This article will introduce five must-know common frameworks in the Go language, with specific code examples to help readers better understand understand and use these frameworks.

---

1. Gin

Gin is a very popular Go language web framework with high performance and simplicity of use. The following is a simple example of using the Gin framework to create an HTTP service:

package main

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

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

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

    r.Run()
}

Run this code to view the returned JSON data by accessing http://localhost:8080/hello.

2. Beego

Beego is another popular Go language web framework that provides many feature-rich components and tools. The following is an example of using the Beego framework to create a simple API:

package main

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

type MainController struct {
    beego.Controller
}

func (this *MainController) Get() {
    this.Ctx.WriteString("Hello, World!")
}

func main() {
    beego.Router("/", &MainController{})
    beego.Run()
}

Run this code and you can view the returned "Hello, World!" by visiting http://localhost:8080 information.

3. Gorm

Gorm is a powerful Go language ORM framework that can simplify database operations. The following is an example of using the Gorm framework to perform basic CRUD operations:

package main

import (
    "fmt"
    "gorm.io/driver/sqlite"
    "gorm.io/gorm"
)

type User struct {
    gorm.Model
    Name  string
    Email string
}

func main() {
    db, err := gorm.Open(sqlite.Open("test.db"), &gorm.Config{})
    if err != nil {
        panic("failed to connect database")
    }
    defer db.Close()

    db.AutoMigrate(&User{})

    user := User{Name: "Alice", Email: "alice@example.com"}
    db.Create(&user)

    var users []User
    db.Find(&users)
    fmt.Println(users)
}

4. Echo

Echo is a lightweight Go language web framework with high performance and flexibility. The following is an example of using the Echo framework to create a simple RESTful API:

package main

import (
    "github.com/labstack/echo"
    "github.com/labstack/echo/middleware"
)

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

    e.Use(middleware.Logger())

    e.GET("/hello", func(c echo.Context) error {
        return c.String(200, "Hello, World!")
    })

    e.Start(":8080")
}

5. Viper

Viper is a Go language configuration management library that can help developers manage application configuration information. The following is an example of using Viper to read configuration files:

package main

import (
    "fmt"
    "github.com/spf13/viper"
)

func main() {
    viper.SetConfigFile("config.yaml")
    viper.ReadInConfig()

    fmt.Println("App Name:", viper.GetString("app.name"))
    fmt.Println("Debug Mode:", viper.GetBool("app.debug"))
}

The above are five must-know common Go language frameworks and their code examples. I hope it can help readers better use these frameworks to develop Go language applications. program. If you are interested in these frameworks, you may wish to try using them to build your own projects to improve development efficiency and code quality.
