  const stdinBuffer = fss.readFileSync(process.stdin.fd)
  const stdin = stdinBuffer.toString()
  let body = {}
  try {
    body = JSON.parse(stdin)
  } catch(e) {
    return await fs.appendFile(`${__dirname}error.log`, `Error while parsing body: ${JSON.stringify(e, Object.getOwnPropertyNames(e))}\n`)
  }
  /*
    replace anything after #! in top first line with output of `which node`

    make calls to other functions/modules here with body variable

    use this to log anything to error.log file in order to fix bugs:
      return await fs.appendFile(`${__dirname}error.log`, '')

    NEVER leave the script running for long time without exiting with code=0,
    because FastCGI won't run again and you will have to reboot your whole server

    i'm pretty sure you can improve code quality here so please someone 
    make fork or pr to this gist
