add to end of app.js

  url: '/cgi-bin/ci.sh',                  // url to call
  method: 'GET',                          // optional, default is get, and can not send post body now
  status: function(response) {            // response json
    return response.status === 'success';
  }
});

add a cgi script in /cgi-bin like default one

#!/bin/bash

echo "content-type: application/json"
echo ""


echo "{\"status\": \":failure\"}"

I known the demo it is stupid, but the shell you can give more imagination of it, I used in my project, because the cicd is not the normal ones liking jenkins and gitlab ci etc. I found the alphasights/walnut it is so simple code and full of features of a ci Monitors, So I change one to make the ci more pure for only status displayed. and with the power of python cgi server, I can invoke bash shell like curl to check my building status ( the curl command copy is builtin the chrome, very very helped me)

and run main.sh in root project

./main.sh

visit http://localhost:8000 you can see it
