# Getting started
## Intro
To start, open Quickstart page [localhost:8020](http://localhost:8020/) for quick access to all the tools
From the quicklaunch page you can open workspace tools, such as code editor or terminal
Demo: Workspace UI
The main code editor of this workspace is [Code-server](https://github.com/cdr/code-server)
Demo: 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](http://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
