Beego:
Beego is a RESTful HTTP framework for the rapid development of Go applications including APIs, web apps and backend services with integrated Go-specific features such as interfaces and struct embedding.
M (models), V (views), C (controllers) each have top level folders. main.go is the entry point.
Installing Beego
Run the below command in your gopath
go get -u github.com/beego/beego/v2
go get -u github.com/beego/bee/v2
Beego has in-built scaffolding support, via the command line tool bee
- Create new applications
- Run an application
- Test the application
- Create routes and more
Create The Core Project
Once installed, from your $GOPATH directory, run the following command, which will scaffold the application, called sitepointgoapp:
bee new sitepointgoapp
Looking at the files, we have:
1.Our bootstrap file main.go
2.The core configuration file conf/app.conf
3.A default controller controllers/default.go
4.A default set of tests in tests/default_test.go
5.A default view template in views/index.tpl
Right, the basic app is ready, now run the below command
bee run
This loads our new application.
Router settings:
beego.Router("/user/home", &controllers.UserController{}, "*:User")
beego.Router("/user/add", &controllers.UserController{}, "get,post:Add")
Here i've used the mysql with ORM. First we need to install the MySQL driver using golang by using the below command
go get -u github.com/go-sql-driver/mysql
The first one imports Beego’s ORM library "github.com/astaxie/beego/orm", the second one provides support for mysql, required because we’re using an mysql database. The third one imports the models we just created, giving them an alias of models.
create the table in MySQL for orm_test and run the below query to create the users table.
CREATE TABLE `users` (
`id` int(11) NOT NULL,
`name` varchar(200) NOT NULL,
`client` varchar(200) NOT NULL,
`url` varchar(200) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
In the main.go we need to register the driver along with database settings like below for mysql
orm.RegisterDriver("mysql", orm.DRMySQL)
orm.RegisterDataBase("default", "mysql", "root:@/orm_test?charset=utf8")
orm.RegisterModel(new(models.User))
Install ORM using
go get github.com/beego/beego/v2/client/orm
command. By using this line we need to insert the record in db using ORM
id, err := o.Insert(&user)
if err == nil {
msg := fmt.Sprintf("User inserted with id:", id)
beego.Debug(msg)
flash.Notice(msg)
flash.Store(&manage.Controller)
} else {
msg := fmt.Sprintf("Couldn't insert new User. Reason: ", err)
beego.Debug(msg)
flash.Error(msg)
flash.Store(&manage.Controller)
}
If we using the sqlite we need to install the GCC and then we need to setup the database setting same as like below in main.go file
orm.RegisterDriver("sqlite", orm.DR_Sqlite)
orm.RegisterDataBase("default", "sqlite3", "database/orm_test.db")
orm.RegisterModel(new(models.User))
Check the http://localhost:8086/user/home we have displayed the home page which we have done.
Beego commands:
1.bee pack The pack command is used to compress the project into a single file. The compressed file can be deployed by uploading and extracting the zip file to the server

2.bee bale - This command is currently only available to the developer team. It is used to compress all static files in to a single binary file so that they do not need to carry static files including js, css, images and views when publishing the project. Those files will be self-extracting with non-overwrite when the program starts
3.bee version - This command displays the version of bee, beego, and go
4.bee generate - generate the particular scaffoldname
