# Develop Backend Program
|
|
|
|
## Clone Code
|
|
|
|
Open the IDE of backend Dev Container, open Terminal, clone your code to the `/Code` directory
|
|
|
|
```sh
|
|
gh auth login
|
|
|
|
cd /Code
|
|
git clone https://github.com/beclab/terminus-app-demo.git
|
|
```
|
|
|
|
You can then open the backend code in the IDE for development.
|
|
|
|
|
|
|
|
## Connect Database
|
|
|
|
In the Dev Container, you can access database details through environment variables. You can do this by adding the database parameters into the container using environment variables when you deploy it.
|
|
|
|
Take `gorm` as an example:
|
|
```go
|
|
import (
|
|
"fmt"
|
|
"os"
|
|
"strconv"
|
|
|
|
"gorm.io/driver/postgres"
|
|
"gorm.io/gorm"
|
|
)
|
|
|
|
|
|
func init() {
|
|
var err error
|
|
|
|
db_host = os.Getenv("DB_HOST")
|
|
db_port, err = strconv.Atoi(os.Getenv("DB_PORT"))
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
db_username = os.Getenv("DB_USER")
|
|
db_password = os.Getenv("DB_PWD")
|
|
db_name = os.Getenv("DB_NAME")
|
|
}
|
|
|
|
|
|
func main(){
|
|
dsn := fmt.Sprintf("host=%s user=%s password=%s dbname=%s port=%d sslmode=disable TimeZone=Asia/Shanghai",
|
|
db_host, db_username, db_password, db_name, db_port)
|
|
db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
## Debug
|
|
|
|
After completing the development, you can run and debug your code in the IDE.
|
|
|
|
|
|
|
|
You can also run your code in the Terminal, for example:
|
|
|
|
```sh
|
|
go run main.go
|
|
```
|
|
|
|
Now, you can debug your interface with your front-end program. |
