    Many frameworks support multi-platform development, allowing web apps to reach a broader audience across various devices.
  5. Community Support:
    Popular frameworks have large and active communities, providing developers with resources, updates, and support.

Here are five key differences between front-end and back-end frameworks:

Development Focus

  • Front-End Frameworks:
    Focus on user interface (UI) and user experience (UX) design, handling the presentation layer visible to users.
  • Back-End Frameworks:
    Deal with the server-side operations, managing databases, authentication, and business logic.

Languages:

  • Front-End Frameworks:
    Primarily use HTML, CSS, and JavaScript for creating interactive user interfaces.
  • Back-End Frameworks:
    Employ various programming languages such as Python, PHP, Ruby, and JavaScript (Node.js) to handle server operations.

Responsibilities:

  • Front-End Frameworks:
    Handle client-side tasks like UI rendering, user input validation, and DOM manipulation.
  • Back-End Frameworks:
    Manage server-side tasks like database interactions, business logic, and server security.

User Interaction:

  • Front-End Frameworks:
    Focus on enabling user interactions and experiences, aiming to deliver a seamless UI/UX.
  • Back-End Frameworks:
    Concentrate on processing user inputs, executing requests, and managing server operations.

Presentation vs. Functionality:

  • Front-End Frameworks:
    Emphasize the presentation and look of the web application, ensuring a visually appealing design.
  • Back-End Frameworks:
    Concentrate on the functionality and performance of the web application, ensuring efficient data processing and handling.

All Types of Web Framework Architectures:

Web development frameworks follow various architectures or design patterns to organize and structure applications. Let’s explore three common architecture types:

Model-View-Controller (MVC):

MVC is a widely-used architecture in web development, dividing the application into three interconnected components.

Benefits:

  • Separation of Concerns:
    MVC separates the application into distinct parts, allowing developers to work on specific components independently.
  • Reusability:
    Models and Views can be reused in different parts of the application, promoting code reusability.
  • Maintainability:
    MVC architecture eases the maintenance process as developers can update individual components without affecting others.

Model View-View-Model (MVVM):

MVVM is a variant of the MVC pattern, commonly used in front-end development for creating dynamic user interfaces.

Benefits:

  • Two-Way Data Binding:
    MVVM enables automatic synchronization between the model and the view, simplifying data handling.
  • Separation of UI and Logic:
    MVVM separates the UI and application logic, enhancing code maintainability and readability.
  • Testability:
    MVVM architecture facilitates unit testing, as the UI logic is separated from the business logic.

Three-Tier Architecture:

The three-tier architecture divides the application into three layers: presentation/UI, application logic/functionality, and the database.

Benefits:

  • Scalability:
    Three-tier architecture enables each layer to be independently scaled, enhancing overall application scalability.
  • Modularity:
    Separation of concerns makes the application modular and easy to maintain.
  • Resilience:
    Isolating layers enhances the application’s resilience, allowing one layer to be updated without affecting the others.

Angular 13: Top New Features and Updates

Angular 13, the latest version of the TypeScript-based web framework was released. The release has brought several essential updates that can be useful for Angular development.

1. TypeScript 4.4 support

TypeScript 4.4 support is now available in Angular 13. It means now we can use many fantastic language features. Moreover, they stopped supporting TypeScript 4.2 and 4.3 also. One breaking change in TypeScript 4.4 that is advantageous for Angular apps is that it no longer implements setters and getters to get a similar type.

The significant highlights of TypeScript 4.4 are:

  • Improved detection of type guards.
  • Default catch variables.
  • Faster incremental builds.
  • The control flow of conditions can be analyzed
  • Symbol and template string pattern index signatures.

2. Version 7.4 of RxJS

The Angular 13 update adds RxJS, a reactive extension for JavaScript, and includes all versions of RxJS up to and including version 7.

For apps created with ng new, RxJS 7.4 has become the default.

Existing RxJS v6.x apps will need to be manually updated with the npm install rxjs@7.4 command. You can always rely on RxJS 7 for new project creation. As for migrations, existing projects should keep on RxJS 6.

3. 100% Ivy and No More Support for View Engine

The legacy View Engine is no longer supported. Now that there is no View engine-specific metadata or older output formats, it eliminates the codebase complicacy and maintenance costs. Ivy is now the only view engine supported by Angular. Ivy can now compile individual components independently of one another, which significantly improves performance and accelerates development times.

By removing the View Engine, Angular can reduce its reliance on ngcc too. There is no more requirement of using ngcc (Angular compatibility compiler) for the libraries created using the latest APF version. The development team can expect quicker compilation as there is no more requirement for metadata and summary files.

4. IE 11 Support Removed

This stands out to be one of the significant Angular 13 features. Angular 13 no longer supports IE11. CSS code paths, build passes, polyfills, special JS, and other parameters that were previously required for IE 11 have now been completely dropped off.

As a result, Angular has grown faster, and it is now easier for Angular to use new browser features like CSS variables and web animations using native web APIs.

During project migration, running the ng update will automatically remove these IE-specific polyfills and reduce the bundle size.

5. Angular CLI Improvements

The Angular CLI is one of the key components of the Angular Puzzle. Angular CLI helps standardize the process of handling the complexities of the modern web development ecosystem by minimizing these complexities on a large scale.

With the release of Angular 13, this framework now includes a persistent build cache as a default feature, which saves built-in results to disk. As a result, the development process will be accelerated. Furthermore, you have complete control over enabling or disabling this feature in current Angular apps.

6. Improvements to Angular testing

The Angular team has made some notable changes to TestBed, which now correctly tears down test environments and modules after each test.

As the DOM now experiences cleaning after tests, developers can anticipate more optimized, less interdependent, less memory-intensive, and quicker tests.

7. Changes to the Angular Package Format (APF)

The Angular Package Format (APF) defines the format and structure of Angular Framework packages and View Engine metadata. It’s an excellent strategy for packaging every third-party library in the web development environment.

Older output formats, including some View Engine-specific metadata, are removed with Angular 13. The updated version of APF will no longer necessitate the use of ngcc. As a result of these library changes, developers can expect faster execution.

8. TestBed updates

The latest Angular update improves the TestBed significantly, as the DOM is cleaned after every test.  In addition to this, the TestBed tears down test modules and environments in a more effective manner.

Therefore, developers using Angular 13 will get faster, less interdependent, memory-intensive, and optimized tests.

9. Creating dynamic components

One Ivy-enabled API update in Angular 13 is a more streamlined method for dynamically constructing a component. ViewContainerRef.create component no longer requires an instantiated factory to construct a component (no longer need to use ComponentFactoryResolver).

Due to the improved ViewContainerRef.createComponent API, it is now possible to create dynamic components with less boilerplate code. Following is an example of creating dynamic components using previous versions of Angular.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef,
private componentFactoryResolver:
ComponentFactoryResolver) {}
createMyComponent() {
const componentFactory = this.componentFactoryResolver.
resolveComponentFactory(MyComponent);
this.viewContainerRef.createComponent(componentFactory);
}
}
[/code]

In Angular 13, this code can become as follows.

[code language=”css”]
@Directive({ … })
export class Test {
constructor(private viewContainerRef: ViewContainerRef) {}
createMyComponent() {
this.viewContainerRef.createComponent(MyComponent);
}
}
[/code]

10. NodeJS Support

Node versions older than v12.20.0 are no longer supported by the Angular framework. Web developers might face certain issues while installing different packages if working with older versions.

16.14.2 is the current stable version of NodeJS. For ensuring seamless deployment of your project, it is recommended to install the latest versions of NodeJS.

Conclusion

The Angular team tries to release a new version update every six months. Now that you know the significant updates and features of the all-new Angular 13. Apart from delivering on the Ivy everywhere promise made in Angular 12 and removing the View Engine altogether, Angular 13 has many impressive features and updates. The framework has become more efficient with inline support for fonts, simplified API, components, and CLI improvements.

The release of Angular 13 enhances the web development process so that the Angular developer can create awesome apps to meet modern web development standards.  If you’re still using Angular 12, it’s time to upgrade your next project with new features.

At Andolasoft, we have expert Angular developers who can help you migrate your existing applications, and also create new web and mobile applications with the best quality. Feel free to book a free consultation with our experts.

How to Make Your React Web App SEO-Friendly

React is an open source library which has been developed and maintained by Facebook for building interactive UI components for both mobile apps and Single Page Applications (SPA).

It runs on JavaScript and is popularly used by developers as it boosts productivity during the development process.

SPA problems with SEO

The way these sites are built makes it harder for search engines to crawl their content.

What happens when you use React without server-side rendering is that the crawler halts on the very first page because it can’t see any hyperlinks to follow. It sends the page to the indexer, which then has to render the page and extracts the hyperlinks, which will then be added to the crawler’s queue. Then the crawler will eventually crawl the next set of pages, and again will stop there because all the links are invisible until the JavaScript is rendered. So it has to wait for the indexer to come back with a new set of URLs to crawl.”

But this can be improved in 2 ways

  1. React Helmet
  2. Isomorphic React Applications

What is a React Helmet?

React Helmet is a library that helps you deal with search engines and social media crawlers by adding meta tags to your pages/components on React so your site gives more valuable information to the crawlers.

React Helmet Usage

Let’s assume we have a React application with a Home Component, which is the landing page of a business which sells products for pets.

[code language=”css”]
Import React from ‘react’;’
Import ProductList from ‘../components/ProductList’;
Const Home = () =>{
Return <ProductList/>
};
Export default Home;
[/code]

This is a basic component that doesn’t include any Meta data useful for search engines and social media crawlers, so we need React Helmet to do it.

To start using React Helmet we need to install the library as follows:

npm install -save react-helmet

Then we need to modify the Home component to start using Helmet in a way that we can use title tags and Meta tags:

[code language=”css”]
import React from ‘react’;
import { Helmet } from ‘react-helmet’;
import ProductList from ‘../components/ProductList’;
const Home = () => {
return (
<>
<Helmet>
<title>Pets – Products</title>
<meta name="description" content="Find all the best quality products your pet may need" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@user" />
<meta name="twitter:creator" content="@user" />
<meta name="twitter:title" content="Pets – Products" />
<meta name="twitter:description" content="Best Products for your pet" />
<meta name="twitter:image" content="url_to_image"/>
<meta property="og:description" content="Best Products for your pet" />
<meta property="og:url" content="pets.abc" />
<meta property="og:site_name" content="Pets – Products" />
<meta property="og:locale" content="en_US" />
<meta property="og:type" content="article" />
<meta property="fb:app_id" content="ID_APP_FACEBOOK" />
</Helmet>
<ProductList /></>)};
export default Home;
[/code]

Isomorphic React Applications

Isomorphic React App is a web app that consists of code that can run on both server and client-side.

An isomorphic app defines whether the client is able to run scripts or not. When JavaScript is turned off, the code is rendered on the server, so a browser or bot gets all Meta tags and content in HTML and CSS.

When JavaScript is on, only the first page is rendered on the server, so the browser gets HTML, CSS, and JavaScript files. Then JavaScript starts running and the rest of the content is loaded dynamically.

The first screen is displayed faster, the app is compatible with older browsers, and user interactions are smoother in contrast to when websites are rendered on the client side.

Building an isomorphic app can be really time-consuming. There are frameworks that facilitate this process. The two most popular solutions for SEO are Next.js and Gatsby.

  1. Next.js is a framework that helps you create react apps that are generated on the server side quickly and without hassle. It also allows for automatic code splitting and hot code reloading.

    Next.js can do full-fledged server-side rendering, meaning HTML is generated for each request right when the request is made.

  2. Gatsby is a free open-source compiler that allows developers to make fast and powerful websites. Gatsby doesn’t offer full-fledged server-side rendering.

    Instead, it generates a static website beforehand and stores generated HTML files in the cloud or on the hosting service. Let’s take a closer look at their approaches.

Server-side rendering with Next.js

  1. The Next.js server, running on Node.js, receives a request and matches it with a certain page (a React component) using a URL address.
  2. The page can request data from an API or database, and the server will wait for this data.
  3. The Next.js app generates HTML and CSS based on the received data and existing React components.
  4. The server sends a response with HTML, CSS, and JavaScript.

Making website SEO Friendly with GatsbyJS

The process of optimizing React applications is divided into two phases: generating a static website during the build and processing requests during runtime.

The build time process looks as follows:

  1. Gatsby’s bundling tool receives data from an API, CMS, and file system.
  2. During deployment or setting up a CI/CD pipeline, the tool generates static HTML and CSS on the basis of data and React components.
  3. After compilation, the tool creates an about folder with an index.html file. The website consists of only static files, which can be hosted on any hosting service or in the cloud.

Request processing during runtime happens like this:

  1. Gatsby instantly sends HTML, CSS, and JavaScript files to the requested page, since they already were rendered during compilation.
  2. After JavaScript is loaded to the browser, the website starts working like a typical React app.

    You can dynamically request data that isn’t important for SEO and work with the website just like you work with a regular single-page react app.

 

Built TimeRun Time

Creating an isomorphic app is considered the most reliable way to make React SEO-compatible, but it’s not the only option.

Conclusion:

SEO-friendliness of single-page applications develop with react is still a challenge. To make an SPA visible for Google crawlers and available for indexing, you might opt for per-rendering or server-side rendering.

Frameworks like Next.js, makes the work of an SEO much easier. You can also overcome the all the SEO-challenges with the help of the above solutions and frameworks.

I hope the above react SEO guide helps you. To develop your new application with react or any further assistance you can contact Andolasoft experienced react developers.

 

ECMAScript 6: What You Need to Know

ES6 is the latest version of JavaScript. While ES5 and ES2015 are still widely used today, ES6 is a significant update from both of them. The ES6 specification was finalized in June 2015, and it’s now supported by all major browsers with some minor exceptions.

ES6 is designed to be easier to read and write than previous versions of JavaScript. Let’s take a look at some of the new features implemented in ES6 that are more intuitive and cleaner than their predecessors.

What is ECMA?

European Computer Manufacturers Association (ECMAScript) or (ES) is a standard for scripting languages like JavaScript, ActionScript and JScript.

It was initially created to standardize JavaScript, which is the most popular implementation of ECMAScript.

What is ECMAScript?

ECMAScript (ES) is a scripting language specification standardized by ECMAScript International.

It is used by applications to enable client-side scripting.

The specification is influenced by programming languages like Self, Perl, Python, and Java etc. Languages like JavaScript, Jscript and ActionScript are governed by this specification.

ECMA Script6’s new features −

  • Support for constants
  • Block Scope
  • Arrow Functions
  • Template Literals
  • Extended Literals
  • Enhanced Object Properties
  • Destructuring
  • Modules
  • Classes
  • Iterators
  • Generators
  • Collections
  • New built in methods for various classes
  • Promises

ECMAScript Versions

ECMAScript Versions

JavaScript let

The let keyword allows you to declare a variable with block scope.

Let and const basically replace var.

You use let instead of var, const instead of var if you plan on never re-assigning this “variable”.

JavaScript let

JavaScript const

The const keyword allows you to declare a constant (a JavaScript variable with a constant value).

Constants are similar to let variables, except that the value cannot be changed.

JavaScript const

Arrow Functions

Arrow functions allows a short syntax for writing function expressions.

This is a different way of creating functions in JavaScript. Besides a shorter syntax, they offer advantages when it comes to keeping the scope of the keyword.

Arrow function syntax may look strange but it’s actually simple.

Arrow Functions

Normal function syntax as below:

Function callMe (name){

console.log(name);

}

Arrow function syntax may look as below:

const callMe = (name) => {

console.log (name);

}

Arrow Functions

When having no arguments, you have to use empty parentheses in the function declaration:

const callMe = () => {

console.log (‘Max!’);

}

When having exactly one argument, you may omit the parentheses:

const callMe = name => {

console.log (name);

}

Arrow Functions

When just returning a value, you can use the following shortcut:

const returnMe = name => name

That’s equal to:

const returnMe = name => {

return name;

}

JavaScript Maps

  • A Map holds key-value pairs where the keys can be any data type.
  • A Map remembers the original insertion order of the keys.
  • A Map has a property that represents the size of the map.

JavaScript MapsJavaScript Sets

  • A JavaScript Set is a collection of unique values.
  • Each value can only occur once in a Set.
  • A Set can hold any value of any data type.

JavaScript Classes

Classes are a feature which basically replace constructor functions and prototypes. You can define blueprints for JavaScript objects with them. Use the keyword class to create a class. Always add a method named constructor ():

Math Methods in ES6

ES6 added the following methods to the Math object:

Math.trunc ()

Math.sign ()

Math.cbrt ()

Math.log2 ()

Math.log10 ()

Spread Operator

The spread and rest operators actually use the same syntax: …  Yes, that is the operator – just three dots.

Its usage determines whether you’re using it as the spread or rest operator.

Using the Spread Operator:

The spread operator allows you to pull elements out of an array (=> split the array into a list of its elements) or pull the properties out of an object.

Here are two examples:

const old Array = [1, 2, 3];

const new Array = […old Array, 4, 5]; // This now is [1, 2, 3, 4, 5];

Spread Operator

Here’s the spread operator used on an object::

const oldObject = { name: ‘Max’  };

const newObject = { …oldObject, age: 28 };

new Object would then be

{

name: ‘Max’,

age: 28

}

The spread operator is extremely useful for cloning arrays and objects. Since both are reference types (and not primitives), copying them safely can be tricky.

With the spread operator you have an easy way of creating a clone of the object or array.

Rest Operator

The rest parameter (…) allows a function to treat an indefinite number of arguments as an array.

E.g:

Function sum (…args) {

let sum = 0;

for (let arg of args) sum += arg;

return sum;

}

let x = sum(4, 9, 16, 25, 29, 100, 66, 77);

Ans: 326

Destructuring

Destructuring allows you to easily access the values of arrays or objects and assign them to variables.

Here’s an example for an array:

const array = [1, 2, 3];

const [a, b] = array;

console.log(a); // prints 1

console.log(b); // prints 2

console.log(array); // prints [1, 2, 3]

Destructuring

Example for an object:

const myObj = {

name: ‘Max’,

age: 28

}

con         st {name} = myObj;

console.log(name); // prints ‘Max’

console.log(age); // prints undefined console.log(myObj); // prints {name: ‘Max’, age: 28}

Destructuring

Destructuring is very useful when working with function arguments.

E.g:

const printName = (personObj) => {

console.log(personObj.name);

}

printName({name: ‘Max’, age: 28});

//prints ‘Max’

Here, we only want to print the name in the function but we pass a complete person object to the function. Of course this is no issue but it forces us to call personObj.name inside of our function

Destructuring

We can condense this code with destructuring:

E.g:

const printName = ({name}) => {

console.log(name);

}

printName({name: ‘Max’, age: 28});

//prints ‘Max’

We get the same result as above but we save some code. By destructuring, we simply pull out the name property and store it in a variable/ argument named name which we then can use in the function body

Conclusion:

ES6 is a newer version of JavaScript that has some useful new features. It’s cleaner and easier to read, and it has a few new syntax features that make coding easier. There are also a lot of new functions that are built into the language that make coding easier.

The main highlight of ES6 is that it makes syntax cleaner, its scope is more restricted, and there are also a lot of new functions built into the language that make coding easier and libraries like Underscore or Lodash unnecessary.

If you want to start using ES6, then you can use a code transpiler like Babel to convert your code to the older ES. Andolasoft has highly experienced JavaScript developers who has expertise in ES6 latest version of JavaScript. Book a free consultation now to get solution on your queries.

ReactJS Basics and Difference Between AngularJS and ReactJS

ReactJS and AngularJS are the most popular front-end JavaScript frameworks today. They both have their own strengths and weaknesses, but that’s why they’re so popular.

Famous YouTubers, plugin makers, and developers around the world are opting for either one over the other.

The two front-end frameworks are so popular because they solve distinct problems and because they do so in a variety of ways.

What is ReactJS?

ReactJS is an open-source JavaScript library that is used for building user interfaces specifically for single-page applications. It’s used for handling the view layer for web and mobile apps. React also allows us to create reusable UI components.

ReactJS is a JavaScript library for building user interfaces. It’s one of many frameworks that have popped up in the past few years as front-end developers seek new ways to build web apps.

React Property

Functional Component in ReactJS

Functional components are some of the more common components that will come across while working in React. These are simply JavaScript functions. We can create a functional component to react by writing a JavaScript function.

Class Components in ReactJS

React class-based components are the bread and butter of most modern web apps built in ReactJS. These components are simple classes (made up of multiple functions that add functionality to the application). All class-based components are child classes for the Component class of ReactJS.

What is AngularJS?

AngularJS is a web application framework developed by Google. It’s used to develop single-page applications that run within the browser. Like other front-end web development frameworks, AngularJS solves a particular problem and provides developers with a set of tools.

Difference between AngularJS and ReactJSAngular vs React

Why do we use ReactJS instead of AngularJS?

Angular is a complete full-blown framework so if somebody wants to make an application or project on Angular they need to learn a lot of things like Typescript in-depth.

MVC also there are so many other concepts to learn such as directives, modules, decorators, components, services, dependency injection, pipes, and templates. In advance topic, it requires learning change detection, zones, AOT (Ahead-of-Time) compilation, and Rx.js. Angular provides a lot of stuff “out of the box”. It has strict coding which gives a clear structuring but there are so many things to learn if somebody wants to enter Angular.

On the other hand, ReactJS is just a library and so it has fewer concepts to learn in comparison to Angular. React uses JSX (JavaScript XML) which is a way of writing HTML into JavaScript. So we need to know the syntax of JSX, how to write components, manage internal state, props for configuration, routing, and state management using Redux. It’s easy to learn quickly.

Web Frameworks

From the above images, it’s clearly mentioned that ReactJS has higher priority than Angular and Google Trends also says ReactJS is the most popular library.

Conclusion:

ReactJS and AngularJS are two front-end web development frameworks that have gained immense popularity in the past few years.

These two frameworks are considered as top-notch choices to build scalable, engaging user interfaces. However, these two frameworks have many differences. They are also designed for different purposes.

Both AngularJS and ReactJS provide developers with a way to create fast, secure, and responsive web and mobile apps. While they both have their own specific advantages, they also have some key differences that you should be aware of.
