API

require('winapi').getIdleTime()

Return the time the system has been idle (since last user interaction - e.g. mouse, keyboard & stuffs, see GetLastInputInfo) This is really usefull if you want to create a screensaver/like in nodejs / node-webkit.

var winapi = require('winapi');

console.log("System is idle since %s", winapi.getIdleTime() );

require('winapi').CreateJobGroup()

Create a job group with current process and all future child_process. Use this to kill zombies. Like Rick.

var winapi = require('winapi');

winapi.CreateJobGroup();

//you can now spawn subprocess and they'll be killed once you died, windows will clean everything up

• (checkout my dispatcher project for inspiration)
• Available for node 8, nw 26 and nw 14. (i did not re-compile other platform binaries, do it by yourself...)

require('winapi').GetLastInputInfo()

Use this native binding to get system last input time (see MSDN )

  console.log("Last input time is %s", winapi.GetLastInputInfo() );
}, 1000);
