Developers use Node.js to add, delete, or manipulate data in the databases, collect form data, and generate the dynamic page content. Further, Node.js can perform different functions on servers like closing, opening, creating, reading, writing, or deleting multiple files. Let us know why developers prefer to use Node.js.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Nodejs\"><\/span>Why Node.js?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/04\/Node.JS_.jpg\" alt=\"Node.JS\" class=\"wp-image-28038\" srcset=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/04\/Node.JS_.jpg 300w, https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/04\/Node.JS_-270x180.jpg 270w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/figure><\/div>\n\n\n<p>Node.js quickly eliminates the wait time and processes continue requests, unlike ASP or PHP. It runs on asynchronous programming, non-blocking, and runs on a single-threaded way. Hence, Node.js is famous as the open-source Chrome\u2019s JavaScript runtime environment that helps create scalable web applications. Node.js can be used for both front-end and <a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/app-backend-development.html\">back-end development<\/a>. Some of the main reasons that Node.js is used by developers globally include<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. High performance<\/h3>\n\n\n\n<p>The high efficiency of Nodes.js is due to the direct compiling of JavaScript code into the machine code. Google has invested a lot in improving the search engine\u2019s performance, while Node.js is highly resource-efficient and accelerates application performance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Increased development speed<\/h3>\n\n\n\n<p>The node js app development paces up using varied and lightweight tools.\u00a0NPM package offers a set of libraries, modules, and solutions to create powerful applications without looking for different platforms. Hence, the time to market of application gets significantly reduced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Single programming language<\/h3>\n\n\n\n<p>Node.js uses JavaScript for front-end and back-end development. Hence, the overall node.js application development remains robust and seamless. The developers can stay productive and profitable while saving on money, resources, and technical skills.<\/p>\n\n\n\n<p>Node.js uses JavaScript for front-end and back-end development.

The developers can stay productive and profitable while saving on money, resources, and technical skills.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Rich ecosystem<\/h3>\n\n\n\n<p>NPM takes charge of the rich ecosystem associated with Node.js. The ever-growing NPM library offers the developers much-needed help and ensures that Node.js remains a close aid in application development.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Full-stack &amp; MEAN stack compatibility<\/h3>\n\n\n\n<p>JavaScript can bring multiple benefits to the different technological stacks like a full-stack, MEAN stack, etc. With the JSON module library, developers are using Node.js for other technical stacks.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Multiple application development<\/h3>\n\n\n\n<p>The developers can create cross-platform applications using Node.js. developers can create applications for desktop, mobile, Linux, Mac, Windows, etc., using popular frameworks like NW.js, Electron, etc.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Broad community support<\/h3>\n\n\n\n<p>Node.js Foundation has a set of professionals from SAP, Fidelity, Microsoft, IBM, etc. Hence, the developers are never alone while using Node.js, which is further supported on Github to offer <a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/web-development-frameworks.html\">dedicated framework<\/a> support.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Scalable<\/h3>\n\n\n\n<p>All Node.js applications are vertically and horizontally scalable. Hence, developers can add more resources to the current nodes in vertical scalability while the new nodes can be added in horizontal scalability. Startups and small businesses can go for Node.js due to the limited use of blocks in application development.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nodejs_Architecture_How_It_Works\"><\/span>Node.js Architecture &amp; How It Works?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Node.js Architecture | NodeJS Architecture Explained | NodeJS Tutorial For Beginners | Simplilearn\" width=\"770\" height=\"433\" src=\"https:\/\/www.youtube.com\/embed\/zFRuGk52X-c?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>It is easy for the developers to start using Node.js by understanding the architecture and working. Node.js works on the \u201cSingle Threaded Event Loop\u201d architecture while maintaining different clients simultaneously. Before jumping to the single thread, it is essential to understand the multiple thread approach. In this, various clients send requests to the server, which are processed, and the responses are sent back accordingly. The multiple threads can process concurrent calls and are defined thread pools. Thus, a specific thread is assigned to a particular request.<\/p>\n\n\n\n<p>Node.js uses limited threads. Hence, the request execution is faster as it utilizes the memory or resources to optimum limits. Overall, the multi-threaded architecture is ideal for data-intensive tasks, while Node.js prefers to go for the single-threaded event loop.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"Node.js Architecture | Mosh\" width=\"770\" height=\"433\" src=\"https:\/\/www.youtube.com\/embed\/XUSHH0E-7zk?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>What does node js do? Node.js\u2019 working can be understood with the help of the following steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>All the requests are served using the limited thread pool maintained by Node.js.<\/li>\n\n\n\n<li>All incoming requests are placed in a queue by Node.js.<\/li>\n\n\n\n<li>The single-threaded event loop waits for the request indefinitely.<\/li>\n\n\n\n<li>This loop picks up the incoming request from the queue and confirms the need for blocking input\/ output (I\/O) operation. The loop accordingly sends the response.<\/li>\n\n\n\n<li>If there is a need to block input\/ output (I\/O) operation, the event loop assigns a thread from the internal thread pool for processing the request. The group of auxiliary threads is called the worker group, and there are limited threads available in the system.<\/li>\n\n\n\n<li>After processing the blocking task, the event loop tracks the blocking request and places them in the queue. Hence, the non-blocking nature of the loop is maintained.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"750\" height=\"400\" src=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Node.js-Architecture.jpg\" alt=\"Node.js Architecture\" class=\"wp-image-28996\" srcset=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Node.js-Architecture.jpg 750w, https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Node.js-Architecture-300x160.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Features_Of_Nodejs\"><\/span>Features Of Node.js<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Once you\u2019re clear with the architecture, it becomes easy to understand the popularity of Node.js based on the main features. The key features of Node.js include the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Easy<\/h3>\n\n\n\n<p>Many newbie developers go for Node.js as it is an easy-to-use technology. Further, it comes with solid support from a large community and several tutorials, making it easy for the developers to solve their queries whenever they are stuck.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Scalable<\/h3>\n\n\n\n<p>Node.js is single-threaded, and hence it can handle a large number of continuous connections with high throughput. Therefore, it is highly scalable for creating multiple applications.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Speed<\/h3>\n\n\n\n<p>Node.js has superior speed and efficiency due to non-blocking thread execution.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Packages<\/h3>\n\n\n\n<p>The range of packages available in the NPM ecosystem ensures that developers don\u2019t have to look beyond. All these packages are open-source and hence can be used by any developer from any location globally.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Robust backend<\/h3>\n\n\n\n<p>Node.js uses C++ and C. Hence, it becomes easy to add networking support and speedy application development.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Multi-platform<\/h3>\n\n\n\n<p>The multi-platform support from Node.js ensures that it is easy for the developers to create <a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/what-is-a-mobile-application.html\">mobile applications<\/a>, desktop applications, and SaaS websites.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Maintainable<\/h3>\n\n\n\n<p>It&#8217;s easy to manage node js front end or back end using JavaScript as the single programming language.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Asynchronous and Event-Driven<\/h3>\n\n\n\n<p>The APIs in the Node.js library are designed to be asynchronous, meaning they don&#8217;t block operations. When a Node.JS server interacts with an API, it doesn&#8217;t pause to wait for its response. Instead, it proceeds to the next task. To monitor and capture responses from earlier API interactions, it employs an alert system known as Events.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Understanding_The_Popularity_Of_Nodejs\"><\/span>Understanding The Popularity Of Node.js<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The popularity of Node.js can be estimated from the quick list of the top companies using it, including GoDaddy, LinkedIn, Reddit, eBay, Spotify, and Twitter.

Modules<\/h3>\n\n\n\n<p>These can be considered the JavaScript libraries used in the Node.js applications to include a set of functions. The \u201crequire ()\u201d function is used to include the module in any Node.js application, where the name of the module is written in the parenthesis. Some of the popularly used modules in Node.js are:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/ CREATING A WEB SERVER\n\/\/ Include modules var http = require('http'); var server = http.createServer(function(req, res){\n\/\/write your code here\n});\nserver.listen(2000);\n\n<\/code><\/pre>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-black-color has-pale-cyan-blue-background-color has-text-color has-background\"><thead><tr><th><strong>Sr. No.<\/strong><\/th><th><strong>Name of module<\/strong><\/th><th><strong>Description<\/strong><\/th><\/tr><\/thead><tbody><tr><td>1&nbsp;<\/td><td>util<\/td><td>It contains utility functions for the developers.<\/td><\/tr><tr><td>2<\/td><td>fs<\/td><td>It contains methods, classes, and events to manage I\/O operations on different files.<\/td><\/tr><tr><td>3<\/td><td>querystring<\/td><td>It contains methods to use query string.<\/td><\/tr><tr><td>4<\/td><td>zlib<\/td><td>It contains methods to decompress or compress multiple files.<\/td><\/tr><tr><td>5<\/td><td>http<\/td><td>It contains events, methods, and classes to create Node.js http server.<\/td><\/tr><tr><td>6<\/td><td>url<\/td><td>It contains methods for URL parsing.<\/td><\/tr><tr><td>7<\/td><td>stream<\/td><td>It contains methods for streaming data management.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">2. Console<\/h3>\n\n\n\n<p>It is the dedicated module that offers a way to debug as the internet browsers provide to the JavaScript console. It helps print messages to stdout and stderr.&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/ WRITING \"Hello world\" to console\nconsole.log(\"hello world\");<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">3. Cluster<\/h3>\n\n\n\n<p>It is the module that offers multi-threading by creating child processes. These run simultaneously and share the same server port. It makes the single-threaded architecture quickly to the multi-threaded.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Including cluster module in the application<\/li>\n<\/ul>\n\n\n\n<pre class=\"wp-block-code\"><code>var cluster = require('cluster');\n\nif(cluster.isWorker){\nconsole.log('Child thread');\n} else {\nconsole.log ('Parent thread');\ncluster.fork();\ncluster.fork();<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Creating child thread by using fork() method<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. Global<\/h3>\n\n\n\n<p>All global objects like strings, modules, and functions are available in different modules. Some of the widely used global objects include:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-black-color has-pale-cyan-blue-background-color has-text-color has-background\"><thead><tr><th><strong>Sr. No.<\/strong><\/th><th><strong>Global objects<\/strong><\/th><th><strong>Description<\/strong><\/th><\/tr><\/thead><tbody><tr><td>1&nbsp;<\/td><td>__filename<\/td><td>It defines the filename of the code.<\/td><\/tr><tr><td>2<\/td><td>exports<\/td><td>It is a reference to the module. exports and is shorter for the developers to type.<\/td><\/tr><tr><td>3<\/td><td>require<\/td><td>It is used to import JSON, local files, and modules.<\/td><\/tr><tr><td>4<\/td><td>module<\/td><td>It is a reference to the current module.<\/td><\/tr><tr><td>5<\/td><td>__dirname<\/td><td>It defines the name of the directory having the application code.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">5. Error Handling<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"750\" height=\"400\" src=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Error-Handling.jpg\" alt=\"Error Handling\" class=\"wp-image-29009\" srcset=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Error-Handling.jpg 750w, https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/05\/Error-Handling-300x160.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><figcaption class=\"wp-element-caption\">Node.js applications experience four types of errors.<br><\/figcaption><\/figure><\/div>\n\n\n<p>Node.js applications may develop four different types of errors, including standard JavaScript errors, system errors, user-specific errors, and assertion errors. The common JavaScript errors are due to coding issues; the system errors are like file doesn\u2019t exist, closed sockets, etc. The user-specific errors include errors entered by the users, while the assertion errors are logic violation errors. All these errors are handled through exceptions.&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>try {\nvar = 1;\nvar n = 1\/O\n}\ncatch (err) {\n\/\/ Handling the error here.\n}<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">6. Streaming<\/h3>\n\n\n\n<p>It is easy to read or write data simultaneously in stream objects. Based on the functions, streaming can be readable, writable, duplex (both readable and writable), or transform (which can manipulate data while reading or writing).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Buffer<\/h3>\n\n\n\n<p>It is the module offering streams handling having binary data only. The empty Buffer of \u201c10\u201d length can be created using \u201c varbuf = Buffer.alloc (10);<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>var buf = Buffer.alloc(10);<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">8. Domain<\/h3>\n\n\n\n<p>It intercepts the unhandled errors in the system. The essential methods used for intercepting errors are internal binding and external binding. In the internal binding, the error emitter executes the code inside the run method. In contrast, the external binding technique explicitly adds the error emitter to the domain using the add method.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">9. DNS<\/h3>\n\n\n\n<p>It allows name resolution and connects the Node.js to the DNS server. Hence, the DNS module can perform name resolution without reliable network communication.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DNS resolve<\/li>\n<\/ul>\n\n\n\n<pre class=\"wp-block-code\"><code>Dns.resolve()<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li>DNS lookup<\/li>\n<\/ul>\n\n\n\n<pre class=\"wp-block-code\"><code>dns,lookup()<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">10. Debugger<\/h3>\n\n\n\n<p>The debugger utility in Node.js can be accessed using the in-built debugging client. It supports simple code inspection. It is easy to use the debugger in the terminal by adding the \u201cinspect\u201d keyword at the start of the JavaScript file name.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>$node inspect myscript.js<\/code><\/pre>\n\n\n\n<div style=\"background-color:#ffd0ae;text-align:center\" class=\"wp-block-genesis-blocks-gb-cta gb-block-cta\"><div class=\"gb-cta-content\"><h2 class=\"gb-cta-title gb-font-size-32\" style=\"color:#32373c\"><span class=\"ez-toc-section\" id=\"Convert_Your_App_Idea_Into_Reality\"><\/span>Convert Your App Idea Into Reality<span class=\"ez-toc-section-end\"><\/span><\/h2><div class=\"gb-cta-text gb-font-size-32\" style=\"color:#32373c\"><p><strong>Let&#8217;s Build A New App Together<\/strong><\/p><\/div><\/div><div class=\"gb-cta-button\"><a href=\"https:\/\/multisitelocal.ezxdemo.com\/enqiry.html?utm_source=blog&amp;utm_medium=gb&amp;utm_campaign=nodejsguide\" target=\"_self\" rel=\"noopener noreferrer\" class=\"gb-button gb-button-shape-rounded gb-button-size-medium\" style=\"color:#ffffff;background-color:#000000\">Get Started<\/a><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Applications_Of_Nodejs\"><\/span>Applications Of Node.js<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After knowing the Node.js parts, it comes down to the critical applications. The essential applications of Node.js which are making it a success in the global development industry, are not limited to the following:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Real-time chats<\/h3>\n\n\n\n<p>Node.js allows streamlined real-time communications. It is highly scalable and is used to build chatbots. It has single-threaded asynchronous nature, which offers simple addition of chat features like push notifications, multi-person chat, etc.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Internet of Things<\/h3>\n\n\n\n<p>Node.js can handle multiple requests quickly and hence can be used for internet of things (IoT) technology. It consists of various sensors which can send small data chunks and pile up them in a large number of requests.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3.&nbsp; Data streaming<\/h3>\n\n\n\n<p>With data streaming gaining worldwide attention, leading companies like Netflix use Node.js for data streaming. It comes with a native streaming API and is lightweight and fast for multiple users\u2019 platforms. The data can be directly streamed to the final destination by piping different requests from the streamers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Complex single-page applications (SPAs)<\/h3>\n\n\n\n<p>The single-page applications need to load the whole application on a single page which hints at the multiple requests. Hence, a number of requests are made in the background for a number of components which is ideally managed by the Node.js\u2019s event loop. It processes the requests in a non-blocking fashion and hence is ideal for complex single-page applications (SPAs).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. REST API-based applications<\/h3>\n\n\n\n<p>It is easy for the servers to communicate with the frontend using REST APIs, which work on Node.js. As JavaScript is ideal for both frontend and backend of website applications, the in-built packages like Koa, Express.js, etc., facilitate the developers to create REST API-based applications.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Node_Used_For\"><\/span>What Is Node Used For?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>After going through the quick applications of Node.js, it is easy to understand the primary uses of Node. Developers have used Node since its launch in 2009 to write JavaScript codes. These codes run directly on the system than on the browser, and hence server-side applications use Node. It allows complete access to the file system, operating system, and other functions needed to create detailed applications.<\/p>\n\n\n\n<p>Node is written in JavaScript, C++, and C and is created on the open-source V8 JavaScript engine. These engines power JS in leading browsers like Google Chrome. V8 being a support to the new features is incorporated into the Node. Hence, Node.js is an open-source server environment and helps developers to run JavaScript on the server.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_A_NodeJs_File\"><\/span>What Is A Node.Js File?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A Node.js file has the extension \u201c.js.\u201d These files are initiated on the server before starting any effect. These files have all the tasks used to execute events of trying to access any port on the server. Hence, a built-in Node.js file helps store, access, and manage data on the operating system. It is available as an \u201cfs\u201d core module in every Node.js project without the specific need to install it. Some of the commonly used features of Node.js files include<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>fs. appendFile to append data to a file,<\/li>\n\n\n\n<li>fs. watchFile to get notified of the changes,<\/li>\n\n\n\n<li>fs. readFile to read data from the files.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Nodejs_Express_Framework\"><\/span>Node.js Express Framework<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The express framework is the flexible Node.js web application framework that offers a range of features used to create mobile and web applications. Node.js express framework is used to design hybrid, multi-pages, and single-page web applications. It offers middleware setups to help applications respond to HTTP requests. The routing tables used to perform different actions on URL and HTTP methods are defined by the Node.js express framework. Further, it establishes the HTML pages to pass arguments to the templates through dynamically rendering.&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>var express = require('express');\nvar app = express();\n\napp.get(\"\/\", function(req,res){\nres.send('Hello World');\n})\nvar server = app.listen(8081,function (){\nvar host = server.adress().adress\nvar port = server.adress().port\n\nconsole.log(\"Example app listening at http:\/\/%s:%s\",host,port)\n})<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Creating_Server_Using_Express\"><\/span>Creating Server Using<em> <\/em>Express<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The server takes client requests through different software like Nginx or Apache, performs the assigned tasks, and sends the responses back to clients. Express is the framework that is used to create a server in Node. Express.js comes as a highly flexible and minimal Node.js web application framework that offers a set of dedicated features for mobile and web applications. Express.js is used to set up middleware in the applications and add route tables. It is easy to install Express using the following command:<\/p>\n\n\n\n<p><strong>Step 1:<\/strong> Open your terminal<\/p>\n\n\n\n<p> <strong>Step 2:<\/strong> Create a file named&nbsp;<code>index.js<\/code>:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>touch index.js<\/code><\/pre>\n\n\n\n<p> <strong>Step 3:<\/strong> Add this JavaScript code to it:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/ import express (after npm install express)\nconst express = require('express');\n\n\/\/ create new express app and save it as \"app\"\nconst app = express();\n\n\/\/ server configuration\nconst PORT = 8080;\n\n\/\/ create a route for the app\napp.get('\/', (req, res) =&gt; {\n  res.send('Hello World');\n});\n\n\/\/ make the server listen to requests\napp.listen(PORT, () =&gt; {\n  console.log(`Server running at: http:\/\/localhost:${PORT}\/`);\n});<\/code><\/pre>\n\n\n\n<p><strong>Note<\/strong>: This simple server has only one working route (<code>\/<\/code>).

It has more than one million packages and is still adding its list of open-source libraries globally. All the additions to NPM are created by open source developers globally and are free to use for all professionals. In addition, it comes with a command-line utility that can be searched from the NPM website.&nbsp;<\/p>\n\n\n\n<p>It is easy to choose from the <a href=\"https:\/\/www.npmjs.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">list of the packages<\/a> and install them using a single command. Moreover, the command-line utility can manage the NPM\u2019s version, set up custom scripts in the projects, review dependencies, etc. Further, the excellent package support of the NPM attracts multiple developers globally.<\/p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe title=\"How to install Node.JS and setup npm (Node Package Manager)\" width=\"770\" height=\"433\" src=\"https:\/\/www.youtube.com\/embed\/Q0HFBy2BtfA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Installing NPM Packages Via CLI<\/h3>\n\n\n\n<p>While installing Node JS, NPM is installed automatically along with it.

Hence, it is easy to use the package anywhere on the device. While initializing a new application, a \u201cpackage.json\u201d file is created by the NPM, which contains different NPM packages. It is easy to define custom scripts, dependencies, and versions according to the requirements. It is easy to use various NPM commands like \u201crun,\u201d \u201caudit,\u201d \u201cpublish,\u201d etc. The process of using these commands can be verified using the \u201cnpm help\u201d command.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>npm install (with no args, in package dir)\nnpm install &#91;&lt;@scope&gt;\/]&lt;name&gt;\nnpm install &#91;&lt;@scope&gt;\/]&lt;name&gt;@&lt;tag&gt;\nnpm install &#91;&lt;@scope&gt;\/]&lt;name&gt;@&lt;version&gt;\nnpm install &#91;&lt;@scope&gt;\/]&lt;name&gt;@&lt;version range&gt;\nnpm install &lt;alias&gt;@npm:&lt;name&gt;\nnpm install &lt;git-host&gt;:&lt;git-user&gt;\/&lt;repo-name&gt;\nnpm install &lt;git repo url&gt;\nnpm install &lt;tarball file&gt;\nnpm install &lt;tarball url&gt;\nnpm install &lt;folder&gt;\n\naliases: npm i, npm add\ncommon options: &#91;-P|--save-prod|-D|--save-dev|-O|--save-optional] &#91;-E|--save-exact] &#91;-B|--save-bundle] &#91;--no-save] &#91;--dry-run]<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Popular Packages In The Node JS <\/h3>\n\n\n\n<p>Some of the popular packages used by the modern developers in the Node JS include:<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1. <a href=\"http:\/\/expressjs.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Express<\/a><\/h4>\n\n\n<div class=\"wp-block-image is-style-rounded\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"180\" height=\"180\" src=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/03\/Express.jpg\" alt=\"Express\" class=\"wp-image-27733\" srcset=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/03\/Express.jpg 180w, https:\/\/multisitelocal.ezxdemo.com\/blog\/wp-content\/uploads\/sites\/2\/2022\/03\/Express-150x150.jpg 150w\" sizes=\"(max-width: 180px) 100vw, 180px\" \/><\/figure><\/div>\n\n\n<p>Popularly called Express.js, it is the Sinatra-inspired web development framework for Node JS.

It is easy to start using a text editor.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/ server.js\nconst http = require('http');\n\nconst hostname = '127.0.0.1';\nconst port = 3000;\n\nconst server = http.createServer((req, res) =&gt; {\n  res.statusCode = 200;\n  res.setHeader('Content-Type', 'text\/plain');\n  res.end('Hello World!

It starts with the HTTP HyperText Transfer Protocol and allows the Node JS to transfer data over it. Hence, in the \u201cHello World\u201d program HTTP module is loaded in the program. Then, the createServer method is used to accept a request and return the response using a status code. The first defined port listens, and hence the first server is created in Node JS.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_EmizenTech_Can_Help_You\"><\/span><strong>How EmizenTech Can Help You?&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Being a leading <a href=\"https:\/\/multisitelocal.ezxdemo.com\/nodejs-development.html\">Node.js development company<\/a>, EmizenTech offers a complete suite of services to our clients, from ideation to design, development, scale, and support.\u00a0<\/p>\n\n\n\n<p>You can <a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/how-to-hire-node-js-developer.html\">hire NodeJS developers<\/a> from EmizenTech if you are looking for extensive experience and experts for your Node.js app development services.

It is used to create applications that require a consistent connection between the browser and the server. Hence, some popular applications created using Node JS include web push notifications, news feeds, and chat.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efa7\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Is Node JS and JavaScript the same?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>No, node JS and JavaScript are not the same. JavaScript is a programming language used for writing website scripts, while Node JS is the JavaScript runtime environment. JavaScript is used on the client-side or front-end development, while Node JS is used in server-side development. Further, JavaScript runs in the browsers, while it is possible to run JavaScript outside browsers using Node JS.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efa8\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Does Google use Node JS?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Yes, Google uses node JS and is the Platinum member of the Node.js foundation. Multiple projects are running on Node JS. Further, Google has a good relationship with Node.js and the V8 JavaScript Engine communities. Numerous employees are working on Node from Google and JavaScript.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efa9\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>What are the skills required for a Node JS developer?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The skills required for a node JS developer are knowledge of front-end technologies like HTML5, CSS3, etc. Further, the developer must have extensive knowledge of frameworks, libraries, web stacks, and JavaScript. Additionally, a developer with an academic background in computer sciences feels it easy to understand the world of node JS.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efaa\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Can I use Node JS instead of PHP?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>PHP is the synchronous programming language, while node JS is asynchronous, non-blocking, and event-driven. Hence, Node JS can be used instead of PHP to create browser-based multiplayer gaming or chat applications. Further, all server-side PHP can be replaced with server-side JavaScript.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efab\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Which is better: Python or Node JS?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Python and Node JS are both popular when it comes to application development. However, Node JS is fast and widely used for real-time applications over Python. Python uses CPython as an interpreter, while Node JS uses JavaScript. Python is ideal for back-end applications, machine learning, and numerical computations when asked for specific uses, while Node JS is ideal for further website development and web applications.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efac\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Is Node.js Frontend Or Backend?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Node.js can be used for frontend or <a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/app-backend-development.html\">backend applications<\/a>. Hence, based on the requirements, developers use Node.js for frontend or backend applications.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-674eff736efad\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \"><strong>Is Node.js A Programming Language?<\/strong><\/h3>\n<div class=\"rank-math-answer \">\n\n<p>Node.js is not a programming language, but it is a runtime environment. Hence, Node.js allows running JavaScript outside the browser.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<div class=\"wp-block-genesis-blocks-gb-accordion gb-block-accordion\"><details><summary class=\"gb-accordion-title\"><strong>You might also like to read<\/strong><\/summary><div class=\"gb-accordion-text\">\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/vue-vs-react.html\">Vue vs. React: Which is better?<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/web-development-frameworks.html\">Top Web Development Frameworks (Frontend &amp; Backend)<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/angular-vs-react.html\">Angular vs. React: Differences, Which is better?<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/vue-vs-angular.html\">Vue vs. Angular: Comparison<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/best-frameworks-for-mobile-app-development.html\">Best Frameworks For App Development<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/multisitelocal.ezxdemo.com\/blog\/programming-languages-for-app-development.html\">Best Programming Language For App Development<\/a><\/li>\n<\/ul>\n<\/div><\/details><\/div>\n\n\n\n<div class=\"wp-block-genesis-blocks-gb-accordion gb-block-accordion\"><details><summary class=\"gb-accordion-title\"><strong>References<\/strong><\/summary><div class=\"gb-accordion-text\">\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.simplilearn.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">SimpliLearn<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.w3schools.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">w3schools<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/kinsta.com\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Kinsta<\/a><\/li>\n<\/ul>\n<\/div><\/details><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Regarding web development, JavaScript has dominated the industry since its launch in 1995.
