Keep an API flooded, but not overwelmed

flood.js

var request = require('request')
var async = require('async')

var url = "https://yourapi"

// status codes and the number of results
var results = {200 : 0, 500: 0};

var requestIt = function(cb) {
    request(url, function (error, response, body) {
        if(error) {
            console.log(error)
            return cb()
        }
        results[response.statusCode]++
        return cb()
    })
}

var me = function() {
    async.forever(
        function(next) {
            async.parallel([ requestIt, requestIt, requestIt, requestIt], function(err) { return next(); })
        },
        function(err) {
            if(err) {
                console.log(err)
            }
        }
    )
}
me()

// give data every second regarding what's being run
setInterval(function() { console.dir(results); }, 1000);
