Best practices of golang framework in different application scenarios

The choice of GoLang framework should be based on the application scenario to maximize application performance and functionality. For HTTP routing and processing, a high-performance router such as Gorilla Mux or Gin is recommended. For database interaction, using ORM tools such as xorm or gorm can simplify interaction with the database. Scheduling tasks can be created and managed using the beego framework's scheduler package or the bull library. When developing RESTful APIs, it is recommended to use frameworks such as Martini, Echo or Kite. In the development of microservice architecture, it is recommended to use frameworks optimized for microservice development such as Echo, Gin or Fiber.

Best practices of GoLang framework in different application scenarios

Introduction

## The #GoLang framework provides developers with the core elements needed to build scalable, robust, and efficient applications. In different application scenarios, it is crucial to choose the right framework to maximize the performance and functionality of the application. This article will explore the best practices of popular frameworks in GoLang and provide practical examples to illustrate their application.

1. HTTP Routing and Processing

• Best Practices: Use a high-performance router like Gorilla Mux or Gin.
• Practical case: Create a simple API server to handle HTTP requests and responses.

package main

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

func main() {
    router := gin.Default()
    router.GET("/user/:id", func(c *gin.Context) {
        c.JSON(200, gin.H{"id": c.Param("id")})
    })
    router.Run(":8080")
}

2. Database interaction

• Best practice: Use ORM tools such as xorm, gorm or gorm2 to simplify interaction with the database.
• Practical case: Use gorm to connect to the database and query data.

package main

import (
    "gorm.io/gorm"
    "log"
)

type User struct {
    ID   uint
    Name string
}

func main() {
    db, err := gorm.Open("mysql", "user:password@tcp(localhost:3306)/database_name?charset=utf8&parseTime=True")
    if err != nil {
        log.Fatal(err)
    }
    var user User
    db.First(&user, 1)
    log.Println(user)
}

3. Scheduling tasks

• Best practice:Use the scheduler package of beego framework or bull etc. Third-party library to create and manage scheduled tasks.
• Practical case: Create a scheduling task to regularly clean up expired records.

package main

import (
    "github.com/robfig/cron"
    "log"
)

func main() {
    c := cron.New()
    c.AddFunc("0 0 0 * * *", func() {
        log.Println("Running cleanup job...")
    })
    c.Start()
    select {}
}

4. API development

• Best practices:Use frameworks like Martini, Echo or Kite, They provide optimized functionality for building RESTful APIs.
• Practical case: Use Martini to build a simple RESTful API.

package main

import (
    "github.com/martini-contrib/render"
    "github.com/go-martini/martini"
)

func main() {
    m := martini.Classic()
    m.Use(render.Renderer())
    m.Get("/", func() string { return "Hello, world!" })
    m.Run()
}

5. Microservice architecture

• Best practice: Use a framework like Echo, Gin or Fiber , these frameworks are optimized for microservices development.
• Practical case: Use Echo to build a simple microservice.

package main

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

func main() {
    e := echo.New()
    e.GET("/", func(c echo.Context) error {
        return c.String(200, "Hello, world!")
    })
    e.Start(":8080")
}
