Before sharing a project that uses credentials, it is important to show a user how to save their credentials within the bash_profile. The reasoning for this is security, and it makes variables globally accessible within the architecture. The example is specifically for OSX and Linux.
Open the ~/.bash_profile using your favorite text editor using Terminal.
nano ~/.bash_profile
Create a new variable and export it. Save and exit.
export API_KEY="KEY"
export API_SECRET="SECRET"
Reload the variables using source.
source ~/.bash_profile
Create a new Go program and name it main.js. Add the fmt and os libraries.
package main
import(
"fmt"
"os"
)
func main(){
// ... code here
}
Use the os library's Getenv function to retrieve the environmental variable and print them out.
APIkey := os.Getenv("API_KEY")
APIsecret := os.Getenv("API_SECRET")
Print out the APIkey and APIsecret using fmt.
fmt.Println(APIkey, APIsecret)

Hello, I think you made a mistake about the file name here
Create a new Go program and name it main.js. Add the fmt and os libraries.
