Wrapper for calling a functions with fixed interval. Useful for refreshing state of a React component 👍

auto-refresh.js

import randomInt from 'random-int'

const REFRESH_INTERVAL = 2 * 60 * 1000 // ms
const REFRESH_TIME_OUT = 30 * 1000 // ms

export function refresh (refreshFn, interval = REFRESH_INTERVAL) {
  let intervalToken

  refreshFn()

  const timeout = randomInt(REFRESH_TIME_OUT)
  const timeoutToken = setTimeout(() => {
    intervalToken = setInterval(refreshFn, interval)
  }, timeout)

  return { timeoutToken, intervalToken }
}

export function stopRefresh (tokens) {
  const { timeoutToken, intervalToken } = tokens

  clearInterval(intervalToken)
  clearTimeout(timeoutToken)
}
