golang framework user manual

The Go framework provides an application framework, dependency management, and utilities. This article explores three popular frameworks: Gin framework: High-performance and easy-to-use, suitable for building web applications. Echo Framework: High performance and scalable, focused on creating RESTful APIs. Beego Framework: A full-stack framework with features such as ORM, routing, and template engines.

Go Framework Usage Guide

The Go framework provides powerful tools for application development. They provide application structure, dependency management, tools, and libraries. In this article, we’ll explore some of the most popular frameworks in Go and show how to use them with practical examples.

Gin Framework

Gin is a popular Go framework known for its high performance and ease of use. It provides a simple API to build web applications.

Practical case:

package main

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

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

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

    r.Run(":8080")
}

Echo framework

Echo framework is also a high-performance Go framework that focuses on expansion flexibility and modularity. It provides a clean and concise API for creating RESTful APIs.

Practical case:

package main

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

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

    e.GET("/", func(c echo.Context) error {
        return c.JSON(http.StatusOK, map[string]interface{}{
            "message": "Hello, Echo!",
        })
    })

    e.Logger.Fatal(e.Start(":8080"))
}

Beego framework

Beego framework is a full-stack Go framework that provides web application A set of functions for program development. It includes ORM, routing, template engine and many more features.

Practical Example:

package controllers

import "github.com/astaxie/beego"

type MainController struct {
    beego.Controller
}

func (c *MainController) Get() {
    c.Data["Website"] = "beego.me"
    c.Data["Email"] = "astaxie@gmail.com"
    c.TplName = "index.tpl"
}

Summary

In this guide, we explored three popular Go frameworks: Gin, Echo and Beego. These frameworks provide rich features that help you build robust and scalable applications. Through the provided practical cases, you can learn how to use these frameworks to solve common problems.
