How to use process-exists - 4 common examples

export default async function() {
  if (!global.appProcess) return
  const pid = global.appProcess.pid
  for (let i = 0; true; i++) {
    // console.log('checking if killed', await processExists(pid))
    if (!(await processExists(pid))) {
      return
    }

    await sleep(100)
    // 10 min
    if (i > 10 * 60 * 10) {
      console.log('App stop timeout')
      return
    }
  }
}

const fkill = async (inputs, options = {}) => {
  inputs = arrify(inputs)

  options.tree = options.tree === undefined ? true : options.tree
  options.ignoreCase = options.ignoreCase || process.platform === 'win32'

  const exists = await processExists.all(inputs)

  const errors = []

  const handleKill = async input => {
    try {
      input = await parseInput(input)

      if (input === process.pid) {
        return
      }

      // Handle killall by process name
      if (typeof input === 'string') {
        const processes = await psList()
        const nameRe = new RegExp(`^${input}$`, options.ignoreCase ? 'i' : '')

const interval = setInterval(async () => {
    const [, isRunning] = await eres(processExists(processName));

    if (!isRunning) {
      clearInterval(interval);
      setTimeout(resolve, 1000);
    }
  }, 500);
});
