     I have a situation where I want to run an endless loop and I have to get data from there. For this, I have to make a Http call and then put the http response in a database, In each iteration, I have to wait for some second.

    To solve this problem I am using async module.

    For this below is the code by using async.forever.

    var async = require("async");
    var http = require("http");
    //Delay of 5 seconds
    var delay = 5000;
        function(next) {
                host: "",
                path: "/"
            }, function(response) {
                // Continuously update stream with data
                var body = "";
                response.on("data", function(chunk) {
                    body += chunk;
                response.on("end", function() {
                    //Store data in database
                    //Repeat after the delay
                    setTimeout(function() {
                    }, delay)
        function(err) {


    In above code, I have used async.forever and after getting a response we will store data in a database and perform any action which we want to perform.
