interval-buffer v1.0.1

Interval Buffer

IntervalBuffer is a data structure for group rapidly serial actions into bursts or bulk actions.

Usage

var IntervalBuffer = require('interval-buffer');
var intervalBuffer = new IntervalBuffer({
	maxSize: 5, 
	interval: 100 #ms
}, function(bufferArray){
	request.post(
		'http://some-url.com/updates', 
		{body: bufferArray},
		function(err, response, callback){
			...handle response
		}
	);
});

intervalBuffer.push({firstName: 'john'});
intervalBuffer.push({lastName: 'wall'});

...

intervalBuffer.push({location: 'great wall of china'})

After 100 ms interval the callback defined at instantiation will be called with the following {firstName: 'john'}, {lastName: 'wall'}, {location: 'great wall of china'}

Bonus

It may make sense to combine the objects into an array into an object

function(updatesArray){
	body = {};
	updatesArray.forEach(update){
		for(var key in update) if update.hasOwnProperty(key) {
			body[key] = update[key];
		}
	}

	request.post(
		'http://some-url.com/updates', 
		{body: body},
		function(err, response, callback){
			...handle response
		}
	);
}

Note while the initial calls may be incremental the final submission is combined and deduplicated.
