wake-lock

😴🙅

Prevent your laptop from sleeping. (macOS only for now.)

Usage

const {WakeLock} = require('wake-lock')

const lock = new WakeLock("Reticulating splines")

// ... reticulate the splines, which process must not be interrupted ...

lock.release()

API

new WakeLock(reasonForLocking, {type: "idle" | "display"})

Creates a new wake lock which will prevent the machine from going to sleep due to idle detection until the lock is released. Forced sleep, e.g. from closing the laptop's lid or a low battery emergency, will not be prevented. Multiple wake locks are allowed: the machine will stay awake until all wake locks are released.

• reasonForLocking String - a descriptive string used by the system whenever it needs to tell the user why the system is not sleeping. For example, "Mail Compacting Mailboxes" would be a useful string.
• options Object (optional)
  • type "idle" | "display" - if "display" is specified, display sleep will be prevented. If "idle" is specified (the default), the display will sleep but the machine will stay awake while the lock is held.

WakeLock.release()

Releases a wake lock, allowing the machine to sleep. Calling this function on a lock that has already been released will throw an error.
