Getting started
Intro
To start, open Quickstart page localhost:8020 for quick access to all the tools
From the quicklaunch page you can open workspace tools, such as code editor or terminal
The main code editor of this workspace is Code-server
Workspace has full-size browser-base terminal
Example: hello world
Check Go version
go version
Create new Go project
mkdir myProject/
cd myProject
go mod init myProject
Create file main.go
package main
import "fmt"
func main() {
fmt.Println("Hello Go")
}
Then test it using the go run command
go run main.go
Dependencies
Go Modules - Go’s dependency management system that makes dependency version information explicit and easier to manage.
Create new Go project
mkdir simpleserver/
cd simpleserver
go mod init simpleserver
Adding a remote module as a dependency manually:
go get github.com/spf13/cobra@latest
Check go.mod
file
cat go.mod
Create file main.go
package main
import "github.com/gin-gonic/gin"
func main() {
r := gin.Default()
r.GET("/ping", func(c *gin.Context) {
c.JSON(200, gin.H{
"message": "pong",
})
})
r.Run()
}
To add module requirements and sums execute
go mod tidy
Run, build and install
go run
- to quickly test your go code and to check the output. But internally it compiles your code and builds an executable binary in a temporary location, launches that temp exe-file and finally cleans it when your app exits.go build
- compile and builds executable in current directory.go build
- will compile and move the executable to executable directory included in $PATH, so that you can run this executable from any path on the terminal.
Run the simple server with
export PORT=8030
go run main.go
Open in browser localhost:8030/ping
Build executable locally
go build
This will create an executable simpleserver
in the same folder.
Build and move to executable folder
go install
Now you can execute anywhere in terminal
export PORT=8030
simpleserver
and the server will start
