Take Your HTTP Server to Ludicrous Speed [I]
 
30:03
Take Your HTTP Server to Ludicrous Speed [I] - Matteo Collina, nearForm Express, Hapi, Restify, or just plain Node.js core? Which framework should I choose? In my journey in nodeland, I always wonder about the cost of my abstractions. require(‘http’) can reach 25k requests/sec, Express 9k, and Hapi 2k. I started a journey to write an HTTP framework with extremely low overhead, and Fastify was born. With its ability to reach an astonishing 20k requests/sec, Fastify can halve your cloud server bill. How can Fastify be so.. fast? We will see start by analyzing flamegraphs with 0x, and then delve into --v8-options, discovering how to leverage V8’s feedback and optimize our code. We will discuss function inlining, optimizations and deoptimizations. We will discuss the tools and the libraries you can use to do performance analysis on your code. In Fastify we reach a point where even allocating a callback is too slow: Ludicrous Speed. About Matteo Collina nearForm Software Architect Websitenearform.com Matteo is a code pirate and mad scientist. He spends most of his days programming in Node.js, but in the past he worked with Ruby, Java and Objective-C. In 2014, he defended his Ph.D. thesis titled "Application Platforms for the Internet of Things". Now he is a Software Architect at nearForm, where he consults for the top brands in world. Matteo is also the author of the Node.js MQTT Broker, Mosca, the fast logger Pino and of the LevelGraph database. Since 2015, he is a Node.js collaborator, where he helps maintaining Streams. Matteo spoke at several international conferences: Node.js Interactive, NodeConf.eu, NodeSummit, LXJS, Distill by Engine Yard, and JsDay to name a few. He is also co-author of the book "Javascript: Best Practices" edited by FAG, Milan. In the summer he loves sailing the Sirocco.

Learn advanced node js, Parsing multipart form data
 
06:18
In the last lesson we actually added an upload stream to our http server, so we can actually upload files. And we took our upload request stream and we piped it to several different writable streams. So, in this lesson, we're actually going to handle parsing the multi-part form data and we're going to use an npm to do that. The work to parse multi-part requests has been done many times over and it's been published to many different npms, so there's a lot of options when it comes to parsing a multi-part form data request. Since we're streaming experts, I've decided to use an npm that also supports streams. All right, so I'm going to come over to my terminal, and before I install multi-party I just want to npm init to create a package.json and I can send it a dash-y just to answer all the questions as yes and then I get a package.json file in my root. It's always a good idea to have a package.json file once you start installing things with npm, so I'm going to go ahead and do an npm install multiparty. And there we go. So now that I have multiparty I'm ready to implement it to help me parse this form. So I can come over here to my server and go to the top of the file and make sure that we include multiparty.
Learn nodejs, Serving JSON data
 
10:36
We can also use the HTTP module to create an HTTP API, or a server whose primary purpose is to serve JSON data. APIs are used to serve data to client applications. These applications typically include mobile apps, and single page websites, but, any client who can make an HTTP request can communicate with an API. So,let's go take a look at our Exercise Files, under the start folder, you will notice that there is an empty JavaScript file called api.js. And then, we have a data folder, and inside the data folder we have an inventory.json file. So, I'm going to go ahead and take a look at this file. So, this is just a JSON file that contains an array of inventory items. Each of these objects represent one of the inventory items. And, a couple of these items are in stock, so if we check the availability node, we can see that we have about three items in stock, here, and one of our items, our K-Eco 225s, are on backorder. So, this is the data that we are going to serve through our API.

The second option we run 2 servers, a node server and a lite server that watches for any changes made to our typescript files then recompiles the code and restarts our server. In these examples I've also included socket.io to send events from the client to the server and vice versa. When only running a node server in OptionA, we need to use gulp to copy over our frontend files into a lib folder inside of our public folder.

What is Rest API? | Creating REST API in Node JS | Node JS REST API | HTTP Methods | Renu Rawat
 
05:28
Hello and welcome to PART-1 of "REST API IN EXPRESS" series. This video (Creating a restful api in express- part 1) teaches what is an application programming interface (API), Why there is a need for API? HTTP Verbs OR Methods, HTTP standards. When you use an application on you mobile phone: - The application connects to the internet and sends the data to the server. - The server then retrieves the data, interpret it, performs necessary actions and sends it back to your Phone. This is what an API is- all of this happens via API. -~-~~-~~~-~~-~- ExpressJS/REST API Tutorials/API Playlist: https://youtu.be/NSOKTV9Udzs Session 1: What is REST API? https://youtu.be/Kw5-xbM1bWo Session 2: Steps to build REST APIS with Express JS https://youtu.be/6QperLQ2NBw Session 3: The complete guid for building rest apis in express js https://youtu.be/NSOKTV9Udzs -~-~~-~~~-~~-~- TABLE OF CONTENT 00:00 Introduction 00:10 What is API? 00:55 What is the requirement for API? 01:48 Introduction to REST APIs 02:26 HTTP VEBS or METHODS 03:00 HTTP standards (Request/Response) 04:25 HTTP routes examples 04:28 Routes for sub-collection resources in REST APIs 05:05 Conclusion AND THANK YOU FOR LISTENING.. WHY HTTP IS STATELESS? HTTP is stateless protocol because each request is executed independently. without any knowledge of the previous requests that were executed before it. which means once the transaction ends, the connection between the browser and the server also ends. What makes the protocol stateless is that in its original design. -- WHAT IS A REQUIREMENT FOR API? Imagine the following scenario, you want to access another app’s data. Perhaps you need all the twitter tweets by the hashtag: #RenuRawat. You’ll: - Email to twitter for a spreadsheet of all the tweets. - Write the business logic to process the spreadsheet. - Save the tweets in the database. It would be impossible to keep the database up-to-date. It would be better and simpler for twitter to provide you a way to query their application to get the data, so that you can use it in your own application. It would be up to date this way. THE MOST IMPORTANT POINT HERE IS, “THE CLIENT (YOUR MOBILE APP) AND SERVER COMMUNICATES WITH EACH OTHER BY HTTP PROTOCOL”. Here, REST comes in the picture. HTTP VERBS OR METHODS HTTP Verbs OR methods tells the type of operation that is going to be performed on the resource. Here, are the standard HTTP methods- GET: Getting a resource. POST: Creating a new resource. DELETE: Deleting an existing resource. PUT: Updating a resource. PATCH: Updating partially OPTIONS: Options is initiated by browser itself. HTTP STANDARDS So, our routes are: GET /api/customers GET /api/customers/1 POST /api/customers PUT /api/customers/1 DELETE /api/customers/1 PATCH /api/customers/1 A resource may have sub-collection resources also. Example- accounts of a customer. The URI in this case be- GET /api/customers/{customerId}/accounts/{accountId} -- Please like my social media page: https://www.facebook.com/saigraceschool https://twitter.com/saigraceschool https://www.instagram.com/saigraceschool To Get Regular Content Updates- https://www.youtube.com/c/renurawat?sub_confirmation=1 #RenuRawat #httpmethods #api #RestAPIInExpress #WhatIsRestAPI #HTTPMETHODS -~-~~-~~~-~~-~- Please watch: "SOLVING COMPOUND PROPORTION QUESTIONS USING ARROW METHOD | COMPOUND PROPORTION | RENU RAWAT" https://www.youtube.com/watch?v=wGZ8aDJft2Y -~-~~-~~~-~~-~-

In the next series we will be using a few different frameworks like Aurilia, Angularjs that uses the created REST API to consume and manipulate the data in our Mongodb. In this, the first part of the Series, the focus will be on explaining what a MEN REST API is all about and learning about the Mongo, ExpressJS and NodeJs SourceCode can be found here: https://github.com/EASV/js-men-restapi-example-2016.git Important Links: https://www.mongodb.com/ http://expressjs.com/ https://nodejs.org/en/ https://github.com/ndelvalle/generator-api http://mongoosejs.com/

nodejs ssl,tls configuration using openssl
 
02:00
The tls module uses OpenSSL to provide Transport Layer Security and/or Secure Socket Layer: encrypted stream communication. Use require('tls') to access this module. openssl genrsa -out mykey.pem 1024 openssl req -new -key mykey.pem -out mykey-csr.pem openssl x509 -req -in mykey-csr.pem -signkey mykey.pem -out my-cert.pem var tls = require('tls'); var fs = require('fs'); var options = { key : fs.readFileSync('mykey.pem'), cert: fs.readFileSync('my-cert.pem') } tls.createServer(options,function(s) { s.write("welcome!\n"); s.pipe(s); }).listen(8000);

Why Node.js is So Popular
 
02:21
Do you know why Node.js is so popular? Node.js handles incoming requests asynchronously. That sounds like it can't get with the program. Actually, because Node.js handles things asynchronously, it is able to handle more requests per minute. Adding a new server lets them handle more requests, too, and without having to revamp the software on the server. And each request is processed more quickly because Node.js doesn't assign a new thread to each incoming connection. I wouldn't have thought of Java as being knotted up, but I can see the issues with it. Or, rather, I've seen the errors from the denied connections. Java times out often, too. That is partially due to the tangle of threads it has trouble handling as they time out. I heard Paypal upgraded to Node.js. Paypal says it handles twice as many requests since switching to Node.js, with the same hardware. That's almost a cost savings, to get better performance with only a software change. That's because Node.js handles more concurrent requests, so it works better when a site is so big it needs lots of servers to serve everyone. And that's on top of serving everyone faster. How can an internet connection get even faster? Paypal reported its response time dropped a fifth of a second, on top of the doubled capacity. That's why Walmart.com switched to it. If only Walmart took similar actions to shorten the lines at their actual stores. But a simple shift to Node.js results in shorter connection times and higher volume, without any cost. Except for the development effort. That's hardly a cost these days given the costs to maintain the servers, protect user information against hack attacks and upgrade software licenses. I heard Netflix has switched. So did the UK Daily Mail. Who cares about the Daily Mail? Netflix, though, that's big, so I suppose Node.js has to be a dramatic improvement over the other options for them to use it. And that's why Node.js is so popular.

Install Nodejs on Windows: How to Use NVM to install and manage NodeJS
 
06:18
In this video you'll learn how to Install Nodejs on Windows. To do this, you will use NVM, the Node Version Manager. Download links: NVM Mac/Linux: https://github.com/creationix/nvm NVM Windows: https://github.com/coreybutler/nvm-windows In the tutorial even though you'll learn how to Install Nodejs on Windows you can use NVM on Mac / Linux machines also. Windows has a nice installer to get NodeJS up and running on your machine but when you want to upgrade or have a need to switch to an older version then you might need the flexibility of NVM. You'll start the tutorial by getting an understanding of what NVM and then go through an installation process. Once installed, you are good to start installing different versions of NodeJS on your Windows machine. Of course, this will also install the relevant version of NPM for you too, The real power of NVM is when you need to switch versions. There are options to view all available versions of NodeJS and you can simply pick the particular version you want and then request to install it. This is really useful when you want to upgrade and install the latest version of NodeJS on Windows but it also provides you with the ability to select older versions if you have an app you are working on that requires it or alternatively you need to set your environment for a particular project to a legacy version. The NVM won't automatically upgrade your NodeJS version to the latest updates so it is up to you to ensure that you have the most up-to-date version for your system.

I show you an easier way to ensure you don't have to muddy up your async await functions with try catch. The 2 options are creating Promises that never throw, or using a simple wrapper function, copying what Go and Lua do.

Michael Neale - CORS: Cross-domain requests with JavaScript
 
13:20
You all know the same origin policy. And you have all probably heard about json-p. But there is a better way: CORS. With oauth, openid, and applications opening up JSON-based endpoints, your browser is the perfect place to combine data into new apps - less server side programming needed. CORS allows you to have your web apps talk directly and securely to any server, not just the origin. It is relatively simple to use, with a few tricks and gotchas. Let me show you how it works and how it can be setup (warning: some servers will be hurt).

Node Js  Session -4 Communication Between Different Technologies called as Web Services
 
01:05:33
- Providing the Communication Between Different Technologies called as Web Services. - In NodeJS we can Develop the WebServices(Rest API) with the help of "express" Module. - "express" is the 3rd party module used to develop the Rest API. - We can download the "express" module by using "package.json" file. - "package.json" file called as node configuration file. - we can download required dependencies by using "package.json" file to develop node application. - we can execute the "package.json" file by using following command "npm install". - all the dependent modules downloads to "node_modules" folder. Step 1: download express module by using "package.json" file ************* 27-10-2017 package.json ************* package.json ------------ { "name":"nareshit", "version":"1.0.0", "description":"test rest api project", "dependencies":{ "express":"latest" } } npm install Step 2: Prepare the server (node server) Ex. server.js //import express module var express = require("express"); //create the rest api object. //"app" object used to develop the Rest API. var app = express(); //create the get request // get( - , - ) taking two parameters @param1 - url @param2 - anonymous function //"req","res" are the predefined objects provided by node engine. //"req" object used to hold the client data like "get parameters", "post parameters",.... //"res" object used to send the "response" app.get("/" , function(req,res){ res.send("From Root Get Request....!"); }); == http://localhost:8080/ app.get("/getRequest",function(req,res){ res.send("getRequst Data....!"); }); == http://localhost:8080/getRequest app.post("/" , function(req,res){ res.send("Default Post Request...!"); }); == http://localhost:8080/ app.post("/postRequest" , function(req,res){ res.send(" PostRequest Data...!"); }); == http://localhost:8080/postRequest app.delete("/" , function(req,res){ res.send("Default delete Request...!"); }); == http://localhost:8080/ app.delete("/deleteRequest" , function(req,res){ res.send(" DeleteRequest Data...!"); }); == http://localhost:8080/deleteRequest --- --- --- app.listen(8080); console.log("Server Listening the Port No.8080");
