One-stop solution—Introduction to Beego development framework

Beego is an open source framework for rapid development of Go applications and is known as one of the most active frameworks in the Go language ecosystem. It is a lightweight web framework built on the Go language and aims to make your web development easier and more efficient by providing a series of tools and class libraries.

Let’s take a look at this powerful one-stop solution.

Features of Beego framework

• Lightweight and high performance: Beego is implemented based on Go language, with simple code and excellent performance. It has its own template engine, ORM framework, and components such as log and configuration management to support rapid development.
• RESTful support: Beego provides powerful RESTful support and can easily implement RESTful API.
• Modularization: Beego’s modular design allows us to combine and replace modules at will, which facilitates code reuse and maintenance.
• Support multiple databases: Beego’s built-in ORM framework supports multiple databases, such as MySQL, PostgreSQL, MongoDB, etc.
• Safe and reliable: Beego has out-of-the-box security features, including CSRF protection, XSS protection and SQL injection protection.

Installation and use of Beego framework

The installation of Beego is very simple, just run the following command:

go get github.com/astaxie/beego

Then you need to download the bee tool, You can quickly build a Beego application through the bee tool:

go get github.com/beego/bee

After the installation is complete, you can run the following command to create a new Beego application:

bee new myapp

You will see a new project folder Created under $GOPATH/src (it is best to set $GOPATH first if you have not set it), which contains some default files and folders.

Next, you can run the following command to start the application:

cd myapp
bee run

Then you can open the browser and enter http://localhost:8080/ in the address bar to access your Beego is available!

Application practice of Beego framework

Let’s take a simple application as an example to demonstrate the application practice of Beego framework.

Step 1: Create a route

In Beego, routing rules can be defined in a file. First, we need to create a file named main.go to define routing rules and related processing functions.

package main

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

func main() {
    // 显示根目录
    beego.Router("/", &controllers.MainController{}, "get:Index")
    beego.Run()
}

In this small example, we use the beego.Router() function to define the root route "/" and map it to the specified processing function Index().

Step 2: Create a controller

In Beego, the controller is the part of our application responsible for processing requests. We need to create a controller for our application called MainController.

package controllers

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

type MainController struct {
    beego.Controller
}

func (c *MainController) Index() {
    c.Ctx.WriteString("Hello Beego!")
}

In this example, we define a controller named MainController and use beego.Controller to extend this structure. There is a handler function called Index() in the controller that will be called when the route is accessed.

Step 3: Start the application

After completing the above steps, we can run the application and see the effect. The following is the command to run the Beego application:

bee run

Open the browser and enter http://localhost:8080/ in the address bar. You can see that our application responds with a "Hello Beego!" message. It means that we have successfully created a Beego application.

Conclusion

Now, you have understood the basic use and features of the Beego development framework. Beego not only has rich functions and easy-to-use interfaces, but is also an open community with a large developer community and a wide range of application scenarios. If you are looking for a fast, efficient, and stable web development framework, Beego framework will be a good choice.
