Detailed explanation of Golang technology stack: tools, frameworks and libraries

The Go technology stack provides a variety of tools, frameworks and libraries to facilitate development: Tools: including Go compiler, code formatting tools, etc., for writing, debugging and optimizing code. Frameworks: including Echo, Gin, Beego, etc., which can be used to quickly build web servers and APIs. Library: Contains gorm, xorm, go-redis, etc., for interacting with databases, processing Redis data, and more.

Golang technology stack detailed explanation: tools, frameworks and libraries

Golang is a dynamically compiled language with rapid development, high Features such as performance and concise syntax. This article will introduce the commonly used tools, frameworks and libraries in the Golang technology stack, and provide practical practical cases.

Tools

• Go: Go language compiler and runtime environment.
• Go fmt: Code formatting tool.
• Go vet: Code inspection tool.

Practical case:

package main

func main() {
    fmt.Println("Hello, world!")
}

Run the following command to format the code:

go fmt main.go

Framework

• Echo: A framework for creating high-performance web servers and APIs.
• Gin: A lightweight web framework focused on performance and ease of use.
• Beego: Full-stack web development framework, providing ORM, template engine and routing.

Practical case:

package main

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

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

Run the following command to start the server:

go run main.go

Library

• gorm: Object-relational mapping (ORM) library for interacting with databases.
• xorm: Another ORM library that supports multiple databases.
• go-redis: Redis client library.

Practical case:

package main

import (
    "github.com/jinzhu/gorm"
    _ "github.com/jinzhu/gorm/dialects/mysql"
)

type User struct {
    ID   uint `gorm:"primary_key"`
    Name string
}

func main() {
    db, err := gorm.Open("mysql", "username:password@tcp(127.0.0.1:3306)/dbname?charset=utf8&parseTime=True&loc=Local")
    if err != nil {
        panic(err)
    }
    defer db.Close()
    db.AutoMigrate(&User{})
}

The above code creates the MySQL database table users, with ID and name field.
