Overview of Modules in Node.js

Node.js is an open source, server-side runtime environment which runs on various platforms like Windows, Linux, Unix and other operating systems. Node.js is built on JavaScript engine and provides ability to build scalable applications. The runtime environment is event-driven and provides asynchronous programming which is memory efficient. Node.js is useful in generating dynamic page contents as it eliminates the need for the wait to open and close files and continues with the next request. We can also use Node.js to modify data in our database. In other languages, it’s usually better to structure our application code and break it into small pieces. However, in ode.js, we can write all our application code in one index.js file, irrespective of the complexity of our application, and the node.js interpreter will not cause issues. But, if we have very complex application, it would be better to divide our application code into small modules and then combine them into a cohesive application. Introduction to Node.js Modules Node.js modules are the different functions which can be reused time and time again. They can be organized into single or multiple JavaScript files in the same or different folders. Each file is treated as a single module. They can also be considered as JavaScript libraries. Every module has its own context and does not interfere in the working of another module. Together, these modules help to run the application.  Before we deep dive into types of modules, let’s take a quick example of creating a simple module.  const average = (a, b) => {return a + b;}; const output = average (2, 3)console.log(output)The above module will calculate the average of two numbers and display the output. Types of Node.js Modules Built-in Modules When we install node.js, several lightweight modules are automatically created, which provide bare minimum functionalities.  These modules are compiled into the node.js binary. They are also referred to as core modules and located in the lib folder. Below are few of the built-in modules in node.js   ModuleCommentsurlUsed for url parsing and resolutionpathIt is used to deal with file paths using methodsfsIt is needed to work with I/OutilIt includes utility functions needs by programmers.httpIt is used to create http server using classes, methods and events.These modules are used in our application code as reference. The code of these modules are not part of our program as they work as libraries. They are always loaded if their identifies is passed to require().  Let’s see an example:var URL = require('url').URL;Here require(‘url’) is what gives us access to url module. The definition of url module is not seen to us. We just need to understand when and how to use it.  Built-in functions have methods and classes which can be used when we require() the module.  For example:var http = require('http');   http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/html'});   res.end ('Welcome to Node.js Modules!');   }).listen(8080);Here, we use the http built in module using the require(‘http’). Once we load the http module, its classes and functions like createServer can also be used.  External Modules Node.js has a huge open source community which really boosts its ecosystem. People from around the globe contribute to the node.js community, which provides access to various modules other than the built in modules. These modules are created to solve specific problems in specific environments and then open sourced for the benefit of others. Since these modules are not part of the library, they cannot be used directly using the require unless we first install the codebase containing the module locally; once this is done, they can be integrated to our codebase. External modules are also known as third party modules and require a package manager that maintains all the modules so that they can be accessed with ease. By default, node.js uses NPM [node package manager) package manager for JavaScript runtime environment. NPM is primarily used to install and maintain external modules in node.js application; we can install the external modules which are needed for the application using NPM. Custom Modules Built in and External modules are provided by others based on their needs. However, there might be cases where you need to build your own module for your application.  Let’s create a module of our own named mydiffreturn Math.diff() * (max - min); } exports. between1and10 = function () { return getdiff (1, 10); };We will put this code in a separate file called mydiff.js which provides helper function that returns a difference of two numbers. This file can provide attributes to the outer world via exports, then index.js can use the exported functionality.   Below is the content of index.jsvar mydiff = require('./mydiff.js'); console.log(mydiff.between1and10());require () will again come into play by making the attributes of local mydiff module available. Module can also allow hiding to hide the functionality of the module which is not needed outside of the module. This can be done simply by not exporting the functionality via exports. In such case even though we will have mydiff.js file specified in index.js it will not be able to access the non-exported function and fail with the following error.  TypeError: mydiff.getdiff is not a functionThis way, we can keep our codebase more organized by hiding the implementation details in a module and exposing only those parts which will be used by other parts of the codebase.  Module Caching When the modules are first loaded, they are cached. This means every call to the require () will get the same object returned for multiple calls if the call is resolved to the same file. This is an important feature as it allows us to load the transitive dependencies for returning partial objects. Module caching is done in an object in a key-value pair and then we can reference the objects using the cache (require.cache). If we delete any key from this object, then we need to reload the module on next require () call. Caching Modules also have some caveats as the modules are cached based on their filenames. If a module is resolved to a different filename based on the location of calling module it is not guaranteed that require () will always return the same object. Also, in case of different case-insensitive file systems, different resolved file systems points to the same file. In such a case, again, cache will treat them as separate which will result in reloading the module multiple times. For example, require (‘. /mydiff’) and require (‘. / Mydiff’) would result in two different objects. Stateful & Stateless modules If a node.js module exposes an instance of some stateful object like db connection or socket etc., it is stateful module. Whereas, if a module exposes stateless entities like classes, methods etc., then it is known as stateless module. If an application codebase uses stateful module, we should follow the singleton pattern so that all other modules requiring stateful module access the same instance. Due to the concept of CommonJs system we don’t have to explicitly wrap our stateful module in Singleton pattern. The first time we use the module, it will be cached for the subsequent require as while caching, node.js uses instance package address as a key. Stateful modules should be used with more caution than stateless modules if used in the tightly coupled architecture. Module Dependencies Any component or piece of information that is needed for the working of the module is regarded as dependency, but the first thing that comes to mind while thinking about the dependencies of node.js is the content of the node_modules folder. From database connection instance to string with file path can be considered as dependency. In a broader classification, dependencies are divided as ‘hardcoded dependency’ and ‘injected dependency’. If you hardcode the name of the dependency inside the module using a require function in the wiring pattern, it is referred to as ‘hardcoded dependency’. If the name of dependency is instead provided as input by external entity, then it is known as ‘dependency injection’. Let’s see some differences between hardcoded dependency and dependency injection. Hardcoded DependencyDependency injectionThey are intuitive and easy to understand.Offer higher reusability.Easy to debug.Difficult to debug.Offer less flexibility as they are tightly coupled.Dependencies are wired at runtime.Unit testing is harder since dependencies are hardcoded.Unit testing is easyConclusion To understand how node.js modules work, we need to know the various functionalities it offers. With this objective in mind, we first looked at the different types of node.js modules. We then explored built in modules, looking at different types of modules and examined what they offer and the advantages of having these modules.  We then saw External modules and walked through how they can be included in our codebase, including how the module code could be hidden if we so wished. Finally, we saw custom modules, their benefits and how to use them effectively. We examined how modules can be cached in modules providing us with performance gains by avoiding reload several times, while also going through some caveats we should be aware of.  We also saw how modules can be stateful and stateless and where both can fit in. Finally, we explored the module dependencies and few differences between them which helps us choose among them as per the need of the application.

What Is a React Component? Write Your First React Component

Prior to ReactJS, Popular frameworks like Angular and Ember were focused more towards model/view/controller like patterns known as MVC. These frameworks tried to provide more functionalities and solve most front-end development problems. ReactJS, however, chose to follow a different path, focusing primarily on views and how we can efficiently render views, thus popularising Component-based Architecture in web development.  I wouldn’t go so far as to say the creators of ReactJS invented the Component-based Architecture pattern, but for sure they saw its benefits and helped popularize this pattern for web development.  But first, what is Component-based Architecture? Component-based Architecture In web development, final output is a fully functional UI. According to component-based architecture, we should see the complete UI as a combination of multiple smaller, reusable, composable, functional components and we should approach the problem in similar fashion. We should build multiple small, composable, functional components which can work together as a complete solution. What is component? So, we understand that in component-based architecture, we are supposed to build plenty of smaller components. But what is a component and how does it look like? The word "component" in software industry means a software package, a service or any module which encapsulate a set of related functionalities. In the context of UI development, a component means a UI element or a collection of UI elements which together provide some set of functionalities. A component could be as small and simple as a heading component which is builtwith single H1 tag and its text or it could be as complex as accordion or tabbed navigation. ReactJS also encourages web developers to build smaller, reusable, composable components.Benefits of using Component Architecture There are lot of discussions about the benefits of using Component Architecture. Some people feel that if we break down the UI in multiple components interacting with each other,then the code base will have too many components and will eventually make the project un-maintainable. But still, this architecture has following benefits: Reusability: It would always be great to avoid writing new code as much as we can and use the existing well tested functionalities. If we have collection of well tested reusable components then definitely, the overall output would be more robust. Faster Development: Reusing the same set of componentswill eventually take less time to develop a functionality. Composability: A big functionality is nothing but a collection of multiple small functionalities. Similarly, it is simpler to build a bigger functionality efficiently if we can compose multiple small components together. Less Maintainability: More reusabilitymeans less code and less code will always lead to less maintenance of code base.React Components React component is basically a collection of one or many UI elements which renders a complete functionality. It can show different behaviours based on different parameters. In ReactJS, these parameters are knownas state of component and props passed to component. So how does a React component looks like? A very simple components looks something like this:import React from "react";  function Greeting({ name }) {    return < h1 >{`Hello ${name}`};  }  ReactDOM.render(, document.getElementById("root"));Alright. But is not recognised by web browsers so won't it throw an error? Above code uses JSX (Syntax extension for JavaScript) and there are tools which actually converts JSX into something understandable by JavaScript engines of web browsers.  JSX JSX is a library which allows us to write HTML (or XML) like syntax in JavaScript file. Then this code goes through a tool which converts it into something understandable by JavaScript engines. It allows us to write HTML in JS. It gives a syntax { }, inside curly bracket, we can write JS code. But still how does the final React component looks like? Below code snippet is a final conversion of above Greeting component. import React from "react";  function Greeting({ name }) {    return React.createElement("h1", null, `Hello ${name}`);  }  ReactDOM.render(  React.createElement("Greeting", { name: "Gully Boy" }, null),  document.getElementById("root")  ); React.createElement is part of React API which actually defines a React element. This data structure will be used by React to render the DOM element later. So now, we understand the need of JSX and benefits of using JSX, We will be using React components using JSX in rest of the article.  Classification of React Components Based on Interactivity Before going into the classification, we need to understand what a state means in React component. state is information that a component itself maintains and which changes with time. The state affects the UI and/or the behaviour of the component. There are two types of components based on interactivity: Stateless Component: When a React componentdoesn't have its own state and it just renders based on the information passed to component (props) or a hardcoded information within the component then such components are called as stateless component. Such type of component doesn't provide any user interactivity with component. For Ex: above Greeting component is a stateless component as it just renders the information (in this case name props) passed to it. Stateful Component: There is other type of component which possesses state. This means based of the state behaviour of component changes. These types of components are known as stateful components. For Example a counter component below:import React, {useState} from 'react';  function Counter() {  const [value, setValue] = useState(0);  const increment = () => {  setValue(value + 1);  }  const decrement = () => {  setValue(value - 1);  }  return (    Decrement  {value}  Decrement    );  }  export default Counter;Counter component has a state value which changes when user clicks on increment or decrement button. there is a span tag which displays the state value and it also gets updated based on user action. So this component is an example of stateful component. Based on Programming Methodology Counter component has a state value which changes when user clicks on increment or decrement button. there is a span tag which displays the state value and it also gets updated based on user action. So this component is an example of stateful component. Based on Programming Methodology There are two type of components based on Programming Methodology Class based Component: A React component can be JavaScript class which implements render method of ReactJS and extends React.Component class. Generally if a component has any state or need to implement any React lifecycle method then we create a class based component. Class based componentmust implement the render lifecycle method which returns the JSX. Stateless component can also be implemented as class based component. For example, Above component can be implemented as class based component like below:import React from 'react';  class Greeting extends React.Component {  constructor(props) {  super(props);  }  render() {  return < h1 >{`Hello ${this.props.name}`};  }  }  export default Greeting; Functional Component: A React component can be JavaScript function which returns JSX. Before Hooks which means before React v16.8, functional component was used only for building stateless component. Functional component takes props as argument and returns JSX. Writing functional code is always better in comparison to class based component because transpiled code for functional component is always shorter than class based component. For example, First implementation of at the top is functional component. Based on Functionality There are two types of components categorised based on functionality. One typeimplementsbusiness logic and the other type is more inclined towards UI. Presentational Component: React components which decide the look and feel of UI are called presentational component. These components can be stateful or stateless components. State of these components are normally UI level state instead of application (business logic) state. These components are reusable and often used to have independent styles. For example: above Greeting component is a presentational component which can we be reused multiple places in application. Container Component: React component which mainly deals with application level state, rarely contains HTML tags and interact with API data are known as container component. This categorisation is basically separation of UI logic and application logic.Component and its lifecycle In React JS, class-based components are extended from React.Component class which provides several lifecycle methods to component. render is also a life cycle method which must be implemented in React component. Other lifecycle methods are optional and can be used to gain more control over the React component. As ReactJS has evolved with time, few lifecycle methods are no longer supported and will be removed from library in coming update. In this article, we will look into the lifecycle methods which are supported by library version 16.4+.  React lifecycleReact lifecycle: https://projects.wojtekmaj.pl/react-lifecycle-methods-diagram/ To understand component's lifecycle methods and their invocation orders, we can divide all the methods in three broad category: Mounting, Updating, Unmounting Mounting: When component mounts then first of all constructor method (if present) is called. constructor method takes props as argument and pass props to the constructor method of React.Component class. Refer the example of class based component above. then getDerivedStateFromPropsstatic method will be invoked. getDerivedStateFromPropstakes two argument - props and state and returnsan object to update the state or returnsnull to update nothing. This lifecycle method is used when the state is dependson props. After getDerivedStateFromPropsmethod, render method is being called which returns the JSX. After render, componentDidMount is called which is the last method in mounting phase. We normally put API calls in componentDidMount lifecycle method. To summaries the mounting of component:constructor constructor(props) { super(props); // code here }getDerivedState From Props static getDerivedStateFromProps(props, state) {  // code here  // return updated state object or null  } render render() {  // code here  } componentDidMount componentDidMount() {  // code here  } Updating:  After a component is mounted, A React component is changed either when the state of component or props passed is changed. on update, first getDerivedStateFromPropsstatic method is called which returns the object to update the state or return null to update nothing. Then shouldComponentUpdate lifecycle method is called which takes two arguments (nextProps and nextState) and return a boolean. This method decides whether render method should be invoked or not. If this method returnstrue then render method will be invoked otherwise component will not get updated. This method is used to optimise the React component by reducing the number of re-renders. if shouldComponentUpdate return true (which is also the default return value of method) then render method will be invoked which updated the component based on updated state or new props. After render method getSnapshotBeforeUpdate method is called. this method is invoked right before the rendered output is committed to DOM. It takes two arguments prevProps and prevState. this method gives access to DOM before React is going to update it with recent changes. For example, you can access last scroll position before update (re-render). Value returned by getSnapshotBeforeUpdate will be passed to componentDidUpdate method which is the next lifecycle method invoked. componentDidUpdate is called right after update occurs. This method takes three arguments prevProps, prevState and snapshot. last argument snapshot will be the value returned from getSnapshotBeforeUpdate lifecycle method. To summarise update phase of component:getDerivedState From Props static getDerivedStateFromProps(props, state) {  // code here  // returns updated state object or null  } should Component Update shouldComponentUpdate(prevProps, prevState) {  // code here  // returns true to re-render the component otherwise return false.   // default is true  } render render() {  // code here  } getSnapshot Before Update getSnapshotBeforeUpdate(prevProps, prevState) {  // code here  } component Did Update componentDidUpdate(prevProps, preState, snapshot) {  // code here  } Unmounting: Last phase of React component is unmount. it invokes the last method of React component's lifecycle componentWillUnmount. this method is called before the component is unmounted and destroyed. Normally, clean up code is put in componentWillUnmount method. we should not call setState method here as component is never going to be re-rendered after unmount. To summarise:componentWillUnmount  componentWillUnmount() {  // code here  }Set up a React project As JavaScript has evolved and tooling has become an essential part of web development. There are many approaches to start a React project but the most popular one is create-react-app (popularly known as CRA). create-react-app is available as NPM module which means to use CRA, one must have NodeJS and NPM installed on machine. Create React project with CRA First check the NodeJS and NPM installation on machine by executing following command: node --version  npm --version  npx –version In case NodeJS is not install then download and install it from https://nodejs.org/en/. Once it is confirmed that NodeJS and NPM is installed on system then execute following command to create a React project: npx create-react-app My First React Project NPX command comes with NPM. It is used to use any NPM without actually installing the NPM. above command will create a new React project with latest version of create-react-app in your current directory. Execute following command to run the project: cd My First React Project npm start This would start a local server at port number 3000 and open default React page in browser.Understanding project generated by CRAAbove image shows the files and folder generated by CRA. let us go through it and understand: package.json: This file contains NPM dependencies, NPM scripts, project name, version etc... public folder: All public assets will be present in public folder like index.html, image or logo etc... src folder: All our JS code including React components will be present in src folder. CRA configured our React project with all the needed tooling required for web development. It configured Webpack, dev server with hot reload ( on file save browser reloads the page to reflect latest change), Eslint, react-testing-library for unit testing React components etc... src/index.js is the starting point of our React project. Project also has one sample React component App.js. You can make changes to App.js and it will be reflected on browser. What type of React Component should I build in 2020 So far, we have learnt different ways of writing React component. Now it is time to choose which pattern should you choose for writing React components. As we have discussed in previous article that ReactJS is moving towards functional programming paradigm and with the introduction of hooks in version 16.8, Writing functional component fulfils most of our use cases.Let's create our first stateful functional component. We will be building a simple counter component. The final output looks like this: Counter component code: import React, { useState } from "react";  import "./Counter.css";  function Counter() {  const [count, setCount] = useState(0);  const increment = () => {  const updatedCount = count + 1;  setCount(updatedCount);  };  const decrement = () => {  const updatedCount = count - 1;  setCount(updatedCount);  };  return (      -   {count}    +      );  } export default Counter; Styles are added in Counter.css .counterContainer {  background-color: #fff;  font-size: 24px;  font-weight: 500;  border: 1px solid #0874ce;  border-radius: 3px;  box-shadow: 1px 1px 4px 0 #0084ff;  }  .counterContainer button {  outline: none;  border: none;  width: 50px;  height: 40px;  background-color: transparent;  font-size: 24px;  font-weight: 500;  cursor: pointer;  }  .counterContainer span {  color: #0084ff;  } We have created a fully functional counter component which can be used anywhere in React application.

AngularJS: Top Use Cases and Reasons to Opt for This Tool

AngularJS represents a structural framework for dynamic web applications. It is an open-source, JavaScript-based front-end web platform primarily developed by Google and a consortium of individuals and companies to solve many of the challenges faced in the development of single-page applications.   AngularJSAngularJS offers flexibility in coding like no other framework due to its simple design architecture. In terms of simplicity, it helps beginners to get started and make improvements to their application projects easily. AngularJS also handles heavy web applications that are exceptionally well loaded with features and components. It allows you to use HTML as your template language and allows you to extend the syntax of HTML to clearly and succinctly express the components of your application. The data binding and dependency injections ensure that we do not need to write a big chunk of code which otherwise we would have ended in writing. And all happens inside the browser making it a perfect partner for any application. The next layer data binding frameworks gains popularity due to strong demand. The foremost known ones are: AngularJS KnockoutJS BackboneJS DurandalJS JavaScriptMVC AngularJS overview AngularJS is a platform and framework that uses HTML and TypeScript to build single-page client applications. The below diagram will give you fair idea of difference in traditional page life cycle vs Single page life cycle : The AngularJS application is written using typescript. It introduces core and optional features when you import a collection of TypeScript libraries into your applications. The architecture of an AngularJS application is based on some fundamental principles.The basic building blocks are NgModules which provide the component compilation background. NgModules compile the related code into functional sets; a collection of NgModules define an AngularJS application. An AngularJS  application often has at least one root module that enables bootstrapping, and usually has a lot more feature modules.We will not go into details as this is out of scope of this article but to give you better understanding of an AngularJS application ,let's look at below example where we are trying to calculate area of rectangle :  Area:     Width:     Breadth: Area: {{width * breadth}} This appears to be normal HTML, with some new markup. A file like this is called a Template in AngularJS. Once AngularJS launches the code, it uses the compiler to interpret and process this new markup from the template. The DOM that is loaded, transformed, and rendered is then called view. The Directives are the first kind of modern markup. We add special actions to items or attributes in the HTML. You would have noticed the new attribute ng-app which is a directive for initializing AngularJS apps automatically.AngularJS also defines an input element directive which adds additional behavior to the element. The directive ng-model stores / updates the value of the input field within / from a variable. Why AngularJS? AngularJS is backed by Google. This is a huge relief for developers to operate on a stable code base that will offer the application maximum support. it's a stable platform to focus on. Many frameworks are nowadays a pure bundling of existing resources. They are an integrated group of tools but they are not very elegant. AngularJS is the next generation platform where each tool was built to function in an integrated manner with any other tool. Please find below some reasons why AngularJS is considered as best among its competitors: MVC inbuilt support Most frameworks enforce MVC by asking you to break your app into MVC components and then allow you to write code to re-string them. This is a lot of work. As a developer we have to just split the framework into MVC components and leave everything to AngularJS for taking care. Declarative User Interface AngularJS uses HTML to describe the user interface within the program. HTML is a more concise and less complex declarative language than the procedural interpretation of the JavaScript interface HTML is also less brittle to reorganize than a JavaScript-written GUI, so things are less likely to break. And when the view is written in HTML, you can put in a lot more UI developers. Data models are POJO The POJO acronym for plain old java objects are being used as data models in AngularJS and it works without superfluous functions getter and setter. You can include and change properties straightforwardly and circle over objects and exhibits voluntarily. Your code will look a lot of cleaner and progressively instinctive, the way mother nature expected. Behaviors with Directive Directives are the way AngularJS brings added functionality to HTML. Imagine a world in which HTML has so many rich elements ( e.g. < accordion>, < grid>, < lightbox>, etc.) that we never have to manipulate a DOM to simulate them.To get some functionality out of the box, all that our app needs to do is assign attributes to items. Flexibility with filter Before displaying data on UI, filters filter the data and may include anything as simple as formatting decimal places on a list, reversing the order of an array, filtering a parameter-based array, or implementing pagination. Filters are designed to be stand-alone features, similar to instructions, independent from your device, but concerned only with data transformations. Less code All the points you have received up to now mean you 're getting to write less code. No need to write your own MVC pipeline. The view is described using more succinct, HTML. Without getters / setters, data models are easier to write. Data-binding means you don't have to manually insert data into the view. Also the directives are different from the software code, they can be written in parallel with limited integration issues by another team. Filters let you manipulate view level data without changing controllers. Unit testing ready The definition of AngularJS would be incomplete without speaking of its readiness for unit test. Dependency Injection (DI) links the whole of AngularJS together. Agular's unit tests will use dependency injection for unit testing .It mocks the data and injects into server. In reality, AngularJS already has a mock HTTP provider for controllers to insert fake server responses. It beats the more conventional way web apps are checked by creating individual test pages that activate a single feature and then communicate with it to see if it is working. Google assisted, and a great community of growth. Supported by IntelliJ IDEA and Visual Studio .NET IDEs. Limitations AngularJSis not a magic bullet. Some of its drawbacks are the backsides of its positive points, some of which are intrinsic to JavaScript inefficiency that could not be solved even with the strongest derivatives of its limitations are listed below: AngularJS is broad and complicated. With multiple ways to do the same thing, it's hard to tell which way is best for a particular task. Mastering AngularJS at the "Hello World" level takes significant effort. Different developers' coding styles and habits can complicate the integration of different components into a complete solution. When the project expands over time, you will most likely need to throw away current implementations and build new ones using different approaches. AngularJS implementations are poor in scale. More than 2,000 watchers will seriously lag behind the UI. This limits the complexity of your AngularJS forms , especially large data grids and lists. Best use cases of AngularJS If you want to build smart lightweight applications, AngularJS is your best bet. This TypeScript-based framework helps you to build interactive SPAs that are safe, maintainable, and easy to check. Some of the popular use cases for AngularJS are as follows: YouTube PlayStation three app for video streaming Anyone who likes to play video games would not have skipped the PlayStation 3 version of YouTube. Considering the vast popularity of YouTube, a structure will be needed. Because Google owns AngularJS, it has been leveraged to introduce a brand-new version of YouTube on PlayStation 3. The flexible architecture has helped Google reinvent the PS3 experience by replacing the traditional operating method with a fully new one.  They replaced mouse movements with basic keystrokes. With AngularJS usability, the features of native apps like YouTube PS3 can be extensively leveraged.AngularJS has made a greater contribution in playback video and smooth scrolling on the YouTube PS3. It's the latest ultra-modern and seamless experience of AngularJS, experienced by the crowd of gamers. eCommerce applications like T-Mobile T-Mobile discovered that its customers had to wait for content to be loaded while connecting to the app. So, to make it quicker and less complicated, they used AngularJS server-side rendering to reduce the time. They also used AngularJS so that they could use HTML parsing for search engine purposes.  This leading telecommunications leader has had tremendous success in their eCommerce app, which has generated a phenomenal search engine traffic. With AngularJS, the application interface has been revamped and turned into a smooth and powerful app. Real-time Data Application like weather.com Weather.com is one of the most popular real-time weather update websites. The credit for its success is given to AngularJS 's modular functionality of modules and directories that enable you to use the features of the app on mobile and smartphone devices.  The framework enables developers to build customizable widgets based on the device's specific needs. Using real-time data and dynamically presenting it made it available on the Web using AngularJS technology. What projects don’t need AngularJS AngularJS is super heroic, but there are situations where you can't use AngularJS. Websites with Static Content Small websites with lower targets and static content. These types of websites are better built with limited technical stacks and do not need to be used by AngularJS, as the technology will only add extra pieces of code that are not required by the website or a specific project. Example: landing pages, educational websites, event pages, etc. Limited Resources and Startups AngularJS is not a good idea to start with for small teams and limited resources. AngularJS needs the skillful tools necessary to solve fast problems in large-scale projects. Technology should also not be used for small projects; it can be developed with other available frameworks and does not require much technological facilitation. Game Apps and Heavy Analytical Apps AngularJS is not a gaming app. Other frameworks, such as React, can be used to build a highly interactive UI in games. AngularJS tests every document object model before it changes its position. It is not recommended to use AngularJS in any app which require strong complex mathematical analytics mostly which is used in gaming. Popular web apps built with AngularJS Sharing a list of some of the renowned web applications that are driven by a versatile and robust AngularJS framework: The Guardian The Guardian is a leading designer and publisher, winning a variety of competitions in these fields. The Guardian website UI is created as an AngularJS app.Guardian.comPayPal Papal is one of the world's largest Internet payment firms. This is another one of the big websites that use AngularJS.Paypal.comJetBlue JetBlue is one of the most famous airline companies in the United States as the online airline portal. The new edition of the JetBlue website uses AngularJS.jetBlue.comLego Lego is one of the world's leading producers of play materials. Its products are traded global and can be virtually explored at www.LEGO.com.Lego.comNetflixNetflixNetflix is an American MNC entertainment company.

It is also one of the biggest websites using AngularJS.YouTube for PS3YouTube App on PlayStationOwned by Google, YouTube is mainly used for video hosting and sharing. This is being developed using AngularJS framework. Conclusion We can conclude that the AngularJS web app development framework surely has a wide range of powerful features that gives AngularJS an edge over its competitors like ReactJS. This is one of the primary reasons large-scale businesses are opting for AngularJS as their preferred choice of web development platform. To summarize the key points about AngularJS. It is easy to learn and master. It makes application stable and fast. A bunch of useful features in one framework. There are tons of reasons why you should choose AngularJS for your next web app. The World loves it. We mastered it.
