- Install the Go extension for VS Code
- Open a folder and create a new file hello-world.go
- Type the following code
package main
func main() {
println("Hello World")
}
- Compile the code using the following command:
go run hello-world.go
- In order to make the directory a module, you need to add a mod file (or initialise it - in Go terms)
go mod init <directory-name>
- This will initialise a go.mod package inside the directory
- Adding external packages to the module:
go get <package-name>
