powerMonitor

Monitor power state changes.

Process: Main

You cannot require or use this module until the ready event of the app module is emitted.

For example:

const electron = require('electron')
  const {app} = electron
  
  app.on('ready', () => {
    electron.powerMonitor.on('suspend', () => {
      console.log('The system is going to sleep')
    })
  })

Events

The powerMonitor module emits the following events:

Event: 'suspend'

Emitted when the system is suspending.

Event: 'resume'

Emitted when system is resuming.

Event: 'on-ac' Windows

Emitted when the system changes to AC power.

Event: 'on-battery' Windows

Emitted when system changes to battery power.

Event: 'shutdown' Linux macOS

Emitted when the system is about to reboot or shut down. If the event handler invokes e.preventDefault(), Electron will attempt to delay system shutdown in order for the app to exit cleanly. If e.preventDefault() is called, the app should exit as soon as possible by calling something like app.quit().
