after-delay

after-delay runs some code once a period of time has passed with after-delay not being called again in that time.

Do you recognise this code?

var timeout;
 
on('someEvent', function () {
    clearTimeout(timeout);
 
    timeout = setTimeout(function () {
        console.log('Event not fired for a second!');
    }, 1000);
});

Using this library, you can write just this:

var afterDelay = require('after-delay');
 
on('someEvent', function () {
    afterDelay('someEvent', function () {
        console.log('Event not fired for a second!');
    }, 1000);
});

It's an entire two lines shorter!

The event name should be unique to each event, and when afterDelay() is called with the same name, the old timeout will be cancelled.

Calling afterDelay() without a function will cause the delay to be cancelled. This behaviour is also aliased to afterDelay.cancel().

Install
