WHY DO WE USE ANGULAR? Angular is a widely used open-source front-end framework. It was initially developed by Google. The usage is to create dynamic and in-demand web applications. Angular’s first version introduced in 2010. The angular framework is having different versions. The highest version is angular 11. This is used by most of the developers as a front-end framework. Angular is a really useful front-end framework used to build single-page applications and it has amazing features which help to make attractive designs. Its features including two-way-binding, RESTful API handling, templating, dependency injection, AJAX handling, etc. Here we have different reasons that prove the facts that why we need angular? Assistance by Google This is the most important and highlighted advantage of angular that is supported by Google. Google team is also using this framework for their applications and they consider angular as a stable framework. TypeScript Angular applications can be build using JavaScript or TypeScript. TypeScript is a superScript of JavaScript. ES support is fully provided by the angular typescript feature. Declarative UI Angular UI is completely built-in HTML. It does not bother about the loading of the page elements. It simplifies the flow and the application runs smoothly. This process is done by Angular itself. Plain old JavaScript Object With Angular, we do not need any addition getter or setter function. The plain old javascript functionality does any functionality easily. Even loops and conditions can be applied directly. Effortless Testing In angular, the testing is so simple. The compiler does the scanning at run time which automatically controls the flow if something is wrong and the developer has to resolve the bug if there is any. Simplified MVC Pattern The angular framework works with the MVC(Model-View-Controller) architecture. It is automatic functionality the user does not have to tell it to divide the controller into different models. It is very much similar to MVVP(model-View_view-Model). Modular Structure The overall code divided into different modules in the form of components, directives, pipes, or services. If the project will be divided into different team members then it would be easy to manage and it will ultimately increase productivity. Code Consistency Code consistency is so important while we are talking about development. Angular provides code consistency throughout the project. Other Angular benefits are given below: In summary, I can say that if you are planning for the project development in the framework the angular is the best choice due to its variety of features and advancements.
MERN STACK DEVELOPMENT MERN stands for Mongo DB, Express server, React.js and Node.js. MERN stack is a basically JavaScript program that is used for easier and faster deploying their full stack applications. These four development technologies are providing an end-to-end framework for the developers to work in and it plays biggest part in the development of web applications. Future scope of MERN: Firstly we discuss Mongo DB Mongo DB is the cross platform and NoSQL database where each information is a document involving the key value pairs that are similar to the JSON objects. Mongo DB is very flexible to use and they creates a schema, tables and data tables etc. Records that are identifiable by a primary key make up the basic set of Mongo Db. Once you installed a Mongo dB, user can provide a space like Mongo shell. Mongo shell provide a JavaScript interface through which the user can interact and perform operations. Why we use Mongo DB? Express Server Express server is a backend framework for Node.js and it is open source. It is designed for building web applications and APIs. Express makes it very easier and simple to write the back-end code very fluently. Express supports many different middleware’s which makes the code smaller and easier to write. Features of Express server: React React is a front-end library that is used for establishing a web user interface. Basically react is used for single page applications and mobile applications because it has ability to handle the changing of data. Why we use React? Node.JS Node JS is runtime JS Environment and it provide a JavaScript environment which allow the user to run their code on the server. Node package manager allow to the user to download thousands of free packages. Features of Node JS: This is the overview of MERN stack development and you can say that MERN stack has bright future ahead. If you are interested to learn MERN stack course and think of a carrier in this field then you can take online/offline mean stack training, we are providing MERN stack training in Jalandhar.

Introduction to the Angular Concepts What is ANGULAR? Angular is a framework for building a single page client side application/desktop application using HTML and Typescript. Angular is fully-featured and it is very flexible to use. Angular is Model View Controller Architecture and therefore, its performance is very high. Angular is open-source and is written in Typescript and compiled into JavaScript. WHY Angular? Following are several reasons why we choose Angular: One question is always in your mind why we choose angular? The massive reason is salary package and its demand. The best example is Netflix and PayPal Architecture of MVC: MVC stands for Model View Controller: Let’s discuss the components: Model: This component manages the application data and carry data between view and controller. View: This component manages with how data is displayed to user. This component sends the request to controller to get the particular data that is requested by user Controller: This component manages the relation between view and model. Controller respond the user input and performing action on data model objects. Installation of Angular npm install @angular/cli -g How to create Angular Project? ng new project name Here, I had given the name Angularproject as project name Moving to next step, they ask you for add Angular routing: and you have to type ‘y’ to sayyes Then command prompt will ask you for adding a style sheet for the project, and you have to type ‘y’ or ‘n’ as per your convince. Finally, your Angular project are created. You can check your Angular project folder structure. Moving on next step, you need to open your text editor (VS Code) and check your folder structure that is created and we need to write code .in command prompt for this. Then we are adding the node module in our project by adding command: That is npm start This command is used for creating a node module in our project. The Node Modules is a directory that is only used for build tools and root defines where libraries will be installed. The Last command of our project is for build and run the application that is created in angular that is ng s (where ng stands for next generation and s stands for serve) Ng serve command builder and serve the application that you had created and it rebuilds, when the application if changes occurred afterwards the project is running the browser. And following screen will appear in the browser. This is the Overview of Angular project and I hope you understand the concept of Angular.

To start with react technology you should have basic knowledge of HTML, CSS and Javascript. React is a javascript library to create single-page applications along with web development. React is one of the most popular front end libraries nowadays. So, here is a step by step react training for beginners. You can also use the online code editors like CodePen or CodeSandbox otherwise download the standard version of Visual Studio Code for local setup. Here is the simplest example of react : What is React React is a flexible and efficient JavaScript library for developing UI(user interfaces). Create a project To create a react project from scratch we need to download visual studio code and Node.js and npm installer (node package manager). To check if a node gets installed or not you can run the command in cmd prompt if you are using Windows Os or run the command in terminal if you are using Mac OS. node –version This command will show you the node version. You can now start with a react project. npx create-react-app react_training This is the syntax to create react project react_training is the name of the project. It will create the react_training folder and will take a few minutes to install the project. Now do change directory and start the server and see the application in your browser with the help of following commands. cd react_trainingnpm start Go to http://localhost:3000 link and you will see the react logo on the browser. Print “Welcome to the online React course”: Form here you can edit the application and add your content as per your requirements. Here I am describing the code to print an online react course! import React from ‘react’;import ReactDOM from ‘react-dom’;import ‘./index.css’;import App from ‘./App’;import * as serviceWorker from ‘./serviceWorker’;var element = React.createElement(‘h1’, { className: ‘greeting’ }, ‘Welcome to the online React course!’);ReactDOM.render(element, document.getElementById(‘root’)); serviceWorker.unregister(); Write the code into index.js file and run it on the server you will see the below output on your browser. Welcome to the online React course! Now before moving further you should know the two most important things that are react components and props. Without a good understanding of these two you can not work with react. React Components React divides the huge UI into a small set of pieces called components. Defining different UI parts into different components makes the process easy for developers. So that’s why react is so effective. React Props Props is a keyword in react and it stands for properties. It is used to display data from one component to another. This blog is for beginners, but if you are interested in react training in Jalandhar then you can visit us at Jalandhar office. We provide online react courses and react training to those students who are eager to learn new things! Other than react if you are looking for online training in Jalandhar then you can visit our office, we are providing training in various trending IT technologies. Happy coding!
Progressive Web Apps are web applications with enhanced features and modern APIs. We can also say that it is a mixture of mobile apps and web apps. • Progressive PWAs – Progressive apps are progressive because it works for every user regardless of browser. One can use these apps all around the world. Progressive web apps work well because they build with progressive enhancement. • Fit To Screen or Responsive – Progressive web apps are responsive. The responsive app means it fits every screen size whether it is mobile, tablets, laptop, or any other device. • No Connectivity dependency – PWAs don’t depend upon the connectivity. These apps work on services, workers, and lower networks or offline. • Mobile Apps like Feel – Apps built in PWAs looks like mobile apps. Their navigation and other features feel like an app instead of a web app. • High Security – These apps serve on HTTPS, so no one can access the app without proper authorization. • Easily Discoverable – Service worker register scope allows search engines to find PWA apps easily. • Customer Engagement – Feature of Push notification makes these apps engage with users easily. Also, PWAs can be shared via URL and no complex installation is required. Differentiate between Native Apps, Traditional Apps, and PWA Apps 1. Native Apps – Native mobile apps are coded in programming languages like Objective C or java for the respective operating system. Features of Native apps: • Most reliable and fast performance • Device hardware’s complete access • It modifies system settings • It can use device’s features like camera, address book and many more • Updates go through the store regulations and then send to the users 2. Traditional Apps – Features of traditional apps: • These apps build using stands like HTML, CSS, and JavaScript • Web apps delivery depends upon the speed of internet • Traditional apps have limited access to the device’s feature • Web apps depend upon the internet connectivity • Web apps can never be installed on your device 3. PWA Apps – Features of Progressive Web Apps: • Updates are instant. • PWAs have limited access to device’s features just like traditional apps • Major disadvantage of PWAs is no IOS support yet
Differentiate Between MVC versus MVP versus MVVM MVC versus MVP versus MVVM As nowadays, in its era of modernization, smart devices like phones and tablets are getting more famous so its operating systems are getting precious. Different technologies, design, and architecture are used in the software development process. The top 3 patterns are: 1. MVC – Model View Controller 2. MVP – Model View Presenter 3. MVVM – Model View View-Model MVP and MVVM are by-products of MVC. The main difference between MVC, MVP, and MVVM is the dependency of each layer on other layer and they’re bound. In MVC, the view is on the top of the architecture then the controller lies beside the view. After the controller, the Model sits below it. Therefore, Views has knowledge of Controller and Controller has knowledge of Model. So, View can directly access Models. In this pattern, there may have security and performance costs that depend upon the complexity of the application. In MVP, the controller’s role is replaced with the Presenter. Presenter and View both are on the same level. Here, Presenter listens to all the events of View and Model and actions between them. But there is no mechanism for binding View and ViewModel. So instead of depending on View for implementation, the Presenter can interact with Views. In MVVM, permits us to build View-specific subsets of Model. This contains logic information and avoids the need to bare the complete Model to View. In this, ViewModel is not required to reference view, the way Presenter does in MVP. In this View is used to expose the data contained in Model. And abstraction of View means less logic required. The complexity of interpretation required may change: it might be so simple or more complex. This issue occurs only in MVVM, but MVC doesn’t have any issue like this as the entire Models are readable and all manipulations like this can be avoided. Click Here To Read More Blogs.
What Is The Difference Between Refreshing Token And Access Token? Tokens are custom-built piece of data that carries required information either for authorize user for performing any action or allow the client to get information about authorization. Basically, tokens are used to help the client to grab the information and use that information to get the resources. The JWT (JSON Web Token) defines a way to represent common token information by the representation. Access token and Refreshing token are explained as follows. Types of Token: There are basically two types of tokens, one is access token and other is refreshing token. Access Token: These token carry the required information to directly access the resources. In other words we can say that when an access token is passed by client to a server, then server can get the information from that token and then use it to check whether the client is authorized or not. Usually, access tokens are short-lived and have an expiration date. Refreshing Token: These tokens carry the information that is required to get new access token or we can say to renew access token. Apart from this we can say, whenever we need to refresh or get a new access token issued by authentication server. Generally, when an old access token is expires then refreshing token takes necessary information and generates a new access token. Moreover, refreshing tokens also expires but are long-lived, and also they are blacklisted by the authorized server. Basically, the common implementation allows direct authorization checks against access token. The refreshing token authorization is split way of handling the three thins of authorization check: It improvises the pattern of access against the authorization sever that is lowers the load and faster the check. Sliding session: It is a session which expires after a period of inactivity. In other word, when there is no activity, then after a while the session expires by itself. It expires quickly and reduces the chance of leaked token. Click here to read more blogs
