SetTimeout – When I say go – go ”  setTimeout()

setTimeout() can be used to schedule code execution after a designated amount of milliseconds. 

var count = 0;
var t = setInterval(function() {
    count++;
    console.log("Interval of 10 ms, count = " + count);
    if (count === 10) {
        clearInterval(t);
    }
}, 10);
setTimeout(function() {
    console.log("Timeout at 200 ms");
},200);

console.log("Running!");

Create your own Module

let request = require('request'),
    api = 'https://api.cryptonator.com/api/ticker/'

function getPrice() {
    return new Promise((done, err) => {
        err('Use One of Our Methods, Please Check API for reference on Methods')
    })
}


getPrice.getCryptoPrice = ((base, crypto) => {
    return new Promise((done, err) => {
        if(typeof base === 'undefined' && typeof crypto === 'undefined') {
            err(`You forgot to provide Base / Cryptic Currency Name`)
        } else {
            let cApi = api + crypto + '-' + base
            request(cApi, (error, response, body) => {
                if(!error && response.statusCode === 200) {
                    done(JSON.parse(body).ticker)
                } else {
                    err(`Sorry, We couldn't get the Price. ` + error)
                }
            })
        }
    })
})


getPrice.getBasePrice = ((base, crypto) => {
    return new Promise((done, err) => {
        if(typeof base === 'undefined' && typeof crypto === 'undefined') {
            err('You forgot to provide Base / Cryptic Currency Name')
        } else {
            let cApi = api + base + '-' + crypto
            request(cApi, (error, response, body) => {
                if(!error && response.statusCode === 200) {
                    done(JSON.parse(body).ticker)
                } else {
                    err(`Sorry, We couldn't get the price. ` + error)
                }
            })
        }
    })
})


module.exports = getPrice

Multipart File Upload in Node.js

var app = require("express")();
var multiparty = require("multiparty");
app.post("/submit", function(httpRequest, httpResponse, next){
var form = new multiparty.Form();
    form.on("part", function(part){
if(part.filename)
{
var FormData = require("form-data");
var request = require("request")
var form = new FormData();
            form.append("thumbnail", part, {filename: part.filename,contentType: part["content-type"]});
var r = request.post("http://localhost:7070/store", { "headers": {"transfer-encoding": "chunked"} }, function(err, res, body){
                httpResponse.send(res);
});
            r._form = form
}
})
    form.on("error", function(error){
        console.log(error);
})
    form.parse(httpRequest);
});
app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.send("<form action='http://localhost:9090/submit' method='post' enctype='multipart/form-data'><input type='file' name='thumbnail' /><input type='submit' value='Submit' /></form>");
});
app.listen(9090);
