osxsleep
osxsleep allows to monitor macOS device's sleep state from Node; additionally, you can query the current power source.
Example usage:
const osxsleep = require('osxsleep');
...
var source = osxsleep.OSXSleep.getPowerSource();
switch(source) {
case osxsleep.POWER_SOURCE_AC:
break;
case osxsleep.POWER_SOURCE_BATTERY:
break;
case osxsleep.POWER_SOURCE_UPS:
break;
}
...
osxsleep.OSXSleep.start(function(sleepstate){
switch(sleepstate) {
case osxsleep.CAN_SLEEP:
if (/* can sleep */) {
return true;
} else {
return false;
}
break;
case osxsleep.WILL_SLEEP:
break;
case osxsleep.WILL_POWER_ON:
break;
case osxsleep.HAS_POWERED_ON:
break;
}
});
...
osxsleep.OSXSleep.stop();
It is important to call stop() in order to unregister the native IOKit sleep state monitor & resources!
