Node.js Sleep()

for those who need Sleep() just like me.

UPDATE: NO LONGER REQUIRES CHILD PROCESS, using deasync instead. It will fall back on self child process mode if deasync fails.

• will make the system wait xxx milliseconds.
• can be used to delay script execution.
• is often used to relax the system in between resource intensive tasks.
• works on every platform x86 + x64 Windows / Linux / OSX

• Existing sleep() solutions use a blocking while loop which uses 100% CPU. This is incredibly stupid.
• Also, many sleep() solutions are only for Windows or only for Linux.

Install using NPM

npm install system-sleep

Use

var sleep = require('system-sleep');
sleep(5000); // 5 seconds

Test

Prints variable y to the console every 1 second during 10 seconds.

var sleep = require('system-sleep');
for (y = 0; y < 10; y++) {
    console.log(y);
    sleep(1000);
}
