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.
