Hello World

  1. Make and enter your project directory

    mkdir -p ./hello/cmd/hello
    pushd ./hello/
    
  2. Initialize your go.mod to your git repository url:

    go mod init github.com/example/hello
    
  3. Create a hello.go

    cat << EOF >> ./cmd/hello/hello.go
    package main
    
    import (
      "fmt"
    )
    
    func main () {
      fmt.Println("Hello, World!")
    }
    EOF
    
  4. Format, build, and run your ./hello

    go fmt ./...
    go build -o hello ./cmd/hello/
    ./hello
    

    You should see your output:

    > Hello, World!
    

How to run a Go program as a service

On Linux:

# Install serviceman (compatible with systemd)
webi serviceman
# go into your programs 'opt' directory
pushd ./hello/

# swap 'hello' and './hello' for the name of your project and binary
sudo env PATH="$PATH" \
    serviceman add --system --username "$(whoami)" --name hello -- \
    ./hello

# Restart the logging service
sudo systemctl restart systemd-journald
