Global

Contains functions available in the global scope (window in a browser context)

Identify an interval started by Js.Global.setInterval.

Identify timeout started by Js.Global.setTimeout.

Clear an interval started by Js.Global.setInterval

Examples

RESCRIPT
/* API for a somewhat aggressive snoozing alarm clock */

let punchSleepyGuy = () => Js.log("Punch")

let interval = ref(Js.Nullable.null)

let remind = () => {
  Js.log("Wake Up!")
  punchSleepyGuy()
}

let snooze = mins =>
  interval := Js.Nullable.return(Js.Global.setInterval(remind, mins * 60 * 1000))

let cancel = () =>
  Js.Nullable.iter(interval.contents, (. intervalId) => Js.Global.clearInterval(intervalId))

Clear a timeout started by Js.Global.setTimeout.

Examples

RESCRIPT
/* A simple model of a code monkey's brain */

let closeHackerNewsTab = () => Js.log("close")

let timer = ref(Js.Nullable.null)

let work = () => closeHackerNewsTab()

let procrastinate = mins => {
  Js.Nullable.iter(timer.contents, (. timer) => Js.Global.clearTimeout(timer))
  timer := Js.Nullable.return(Js.Global.setTimeout(work, mins * 60 * 1000))
}

Repeatedly executes a callback with a specified interval (in milliseconds) between calls. Returns a Js.Global.intervalId that can be passed to Js.Global.clearInterval to cancel the timeout.

Examples

RESCRIPT
/* Will count up and print the count to the console every second */

let count = ref(0)

let tick = () => {
  count := count.contents + 1
  Js.log(Belt.Int.toString(count.contents))
}

Js.Global.setInterval(tick, 1000)

Repeatedly executes a callback with a specified interval (in milliseconds) between calls. Returns a Js.Global.intervalId that can be passed to Js.Global.clearInterval to cancel the timeout.

Examples

RESCRIPT
/* Will count up and print the count to the console every second */

let count = ref(0)

let tick = () => {
  count := count.contents + 1
  Js.log(Belt.Int.toString(count.contents))
}

Js.Global.setIntervalFloat(tick, 1000.0)

Execute a callback after a specified delay (in milliseconds). Returns a Js.Global.timeoutId that can be passed to Js.Global.clearTimeout to cancel the timeout.

Examples

RESCRIPT
/* Prints "Timed out!" in the console after one second */

let message = "Timed out!"

Js.Global.setTimeout(() => Js.log(message), 1000)

Execute a callback after a specified delay (in milliseconds). Returns a Js.Global.timeoutId that can be passed to Js.Global.clearTimeout to cancel the timeout.

Examples

RESCRIPT
/* Prints "Timed out!" in the console after one second */

let message = "Timed out!"

Js.Global.setTimeoutFloat(() => Js.log(message), 1000.0)
