noidle

noidle

Spawns an instance of pmset noidle which prevents a macOS computer form going to sleep.

usage

const noidle = require('noidle')

noidle()
  .then(pmsetPid => console.log(pmsetPid))
// stay awake indefinitely

noidle(435)
  .then(pmsetPid => console.log(pmsetPid))
// stay awake for as long as the process with the pid 435 is running

noidle(436, (err, pmsetPid) => console.log(pmsetPid))
// alternative way of invoking with a callback

api

noidle([pid])

Returns a promise which resolves with the pid of the underlying pmset instance. If called with a pid, noidle will run until the associated process quits. The watcher spawns detached and keeps running independently of the node process which invoked noidle. In this case - the returned pid is that of the detached node process.

In older versions of macOS pmset noidle was the way to go if you wanted to force your computer to stay awake. In later versions of the OS, Apple shipped a new tool: caffeinate. To run that instead, have a look at: caffeinate. Or if you prefer a more high level module which automatically runs the preferred method depending on system version: vaka might be what you are looking for.
