What is bee in golang

The bee in golang refers to a tool that assists in the rapid development of beego projects. Through the bee tool, you can easily create, hot compile, develop, test and deploy the beego project. After installing the bee tool , you need to add "$GOPATH" to the environment variable.

The operating environment of this tutorial: Windows 10 system, GO version 1.20, Dell G3 computer.

bee tool introduction

bee is a tool that assists in the rapid development of beego projects. Through bee, you can easily create, hot compile, and develop beego projects. Test, and deploy.

Installation of bee tool

You can install the bee tool in the following ways:

After installation, the bee executable file is stored in $ by default GOPATH/bin, so you need to add $GOPATH/bin to your environment variables before proceeding to the next step.

If you have GOBIN set up on your machine, the above command will be installed under GOBIN. Please add GOBIN to your environment variables

Expand knowledge

Beego is an application Web framework developed using Go language. The framework was started in 2012. The purpose is to provide everyone with an efficient Web application development framework. The framework uses module encapsulation and is easy to use. , easy to learn. For programmers, beego is very simple to master. They only need to focus on business logic implementation. The framework automatically provides different module functions for project needs.

Beego can be used to quickly develop various applications such as API, Web, and back-end services. It is a RESTFul framework. The main design inspiration comes from the three frameworks of tornado, sinatra, and flask, but it is combined with Go itself. A framework designed for some features (interface, struct inheritance, etc.).

Features

Simplification: supports RESTful style, MVC model; you can use bee tool classes to improve development efficiency, such as monitoring code modifications for hot compilation, automated testing of code, and Rich development and debugging functions such as automated packaging and deployment. Intelligent: The beego framework encapsulates the routing module, supports intelligent routing and intelligent monitoring, and can monitor memory consumption, CPU usage and goroutine running status, making it convenient for developers to monitor and analyze online applications. Modularization: beego decouples and encapsulates code according to functions, forming independent modules such as Session, Cache, Log, configuration parsing, performance monitoring, context operations, ORM, etc., to facilitate developers to use High performance: beego adopts Go native http requests, goroutine's concurrency efficiency can cope with high-traffic web applications and API references.

Beego organizational structure

Project configuration: conf

Controller: controllers

This directory is the directory where the controller files are stored The so-called controller is to control which business logic the application calls. After the controllers process the HTTP request, they are responsible for returning it to the front-end caller.

Data layer: models

The models layer can be interpreted as the entity layer or the data layer. User and business data processing is implemented in the models layer. Some operations mainly related to database tables will be placed in Implement it in this directory, and then return the execution result data to the controller layer. The operations of adding, deleting, modifying and checking are all implemented in models.

Routing layer: routers

The routing layer, that is, distribution, distributes the incoming requests the day after tomorrow. When the browser makes an http request to reach the background web project, it must be The program can perform different business processing according to the browser's request URL. From accepting front-end requests to judging the process of executing specific business logic, routers can be implemented.

Static resource directory: static

In the static directory, the static resource files of the web project are stored, mainly including css, img, js, and html files. The static page files of the application will be stored in html.

View template: views

What is stored in views is the directory where the application stores HTML template pages. The so-called template means that the page frame and layout have been written in HTML. You only need to When accessing and displaying, dynamically filling the obtained data into the page can improve rendering efficiency. Therefore, template files are a very common way.

The architecture of the entire project is the operating mode of MVC.
