It operates on a clear and well-defined architecture that enables VueJs developers to build dynamic and interactive web applications.

Its core concepts include reactive data binding, a virtual DOM, component-based architecture, and a set of lifecycle hooks.

Let’s dive into how the framework works:

  1. Reactive Data Binding:

Reactivity is a fundamental concept in VueJs. It refers to the automatic synchronization of data between the application’s state and the user interface.

When data changes, the UI updates accordingly, and vice versa. This is achieved through the reactivity system, which uses JavaScript getters and setters to track dependencies and trigger updates.

  1. Virtual DOM:

It employs a Virtual DOM, a lightweight representation of the actual DOM present in web browsers. The Virtual DOM acts as an intermediary layer between the application’s state and the real DOM.

When data changes occur, it generates a new Virtual DOM based on the updated state.

The key advantage of the Virtual DOM is that it minimizes the number of direct manipulations to the real DOM.

Instead of re-rendering the entire page, it calculates the difference between the previous and current Virtual DOMs, known as the “diff.”

It then efficiently applies these changes to the real DOM, resulting in faster rendering and improved performance.

  1. Component-Based Architecture:

It encourages the use of components, which are self-contained units of UI and functionality. Each component encapsulates its own template, JavaScript logic, and styles.

Components can be nested within one another, allowing developers to build complex user interfaces in a modular and organized manner.

The component-based architecture promotes code reusability, maintainability, and collaboration.

Components can be easily reused across different parts of the application or even in other projects, enhancing developer productivity.

  1. Lifecycle Hooks:

VueJs components have a series of lifecycle hooks that provide developers with control over the component’s behavior during different stages of its lifecycle. These hooks include created, mounted, updated, and destroyed, among others.

  1. Directives and Template Syntax:

The framework provides a concise and intuitive template syntax that allows developers to declaratively render UI elements.

Directives are special attributes that are used to manipulate the DOM, apply logic, and handle user interactions within the templates.

Angular 13: Top New Features and Updates

Posted on by Anurag Pattnaik

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.

How to Make Your React Web App SEO-Friendly

Posted on by Anurag Pattnaik

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.

Server side rendering with Nextjs

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.
