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 advantages 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.

How to Make a React Web App SEO-Friendly

 

What is React?

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.

Import React from ‘react’;’

Import ProductList from ‘../components/ProductList’;

Const Home = () =>{

Return <ProductList/>

};

Export default Home;

 

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:

What's New Features in Laravel 9? — Top Features & Updates

 

Laravel has been one of the most popular PHP frameworks for many years and for a long time now. It is adaptable, scalable, versatile, and has become one of the in fact the systems for engineers and companies working with PHP.

Initially it scheduled to be released by September 2021, Laravel 9 was pushed to January 2022, making it the first long-term bolster (LTS) release to be introduced following the 12-month release cycle.

Here are the expert views,

“I’m finding the Laravel 9 release is much more of a minor “maintenance” release compared to other previous major Laravel releases. Committing ourselves to only 1 “major” release a year really pushed us to ship a bunch of stuff we would have typically held back for a major.”- Taylor Otwell - Founder and CEO of Laravel

“Laravel 9 doesn’t have as many headline features as a normal Laravel release because the team have been focusing on releasing new features throughout the year now that they’ve moved to a yearly release cycle. There’s a pretty comprehensive list of the new features at https://laravel-news.com/laravel-9. The one thing that isn’t mentioned there that I’m excited about is the new support for generics on the Collection class which will really help improve static analysis.”- Jess Archer - Odcast Co-hoster at the BaseCode

How to Structure Your Sass Codebase

 

SASS (Syntactically awesome style sheets) is an extension of the CSS which adds syntactic power to the basic CSS language making it easier for developers to write CSS. It is just a CSS preprocessor, so that you can write CSS in an easy and convenient way.

“Sass is a meta-language on top of CSS that's used to describe the style of a document cleanly and structurally, with more power than flat CSS allows. Sass both provides a simpler, more elegant syntax for CSS and implements various features that are useful for creating manageable style sheets.” 

“Sass is an extension of CSS3, adding nested rules, Variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.”

It’s Sass not SASS. Sass doesn’t stand for anything, except maybe making your CSS Sassier. Sass makes CSS more Sassy because it’s a preprocessor. Preprocessors make writing code easier.

If it helps you making CSS more like a real programming language. If that doesn’t help, just think of it as a way to write CSS that’s cleverer.

Way To Use Flexbox In Web Projects

 

Flexbox is a powerful CSS feature that allows you to easily and efficiently manage the layout of your website. It makes it easy to create responsive designs, or even integrate dynamic resizing if you want. Flexbox is one of the most powerful CSS features for layout. It makes it easy to align elements, resize them appropriately and adapt to different screen sizes.

Why FlexBox

Flexible boxes, or flexbox, is a new layout mode in CSS3.The Flexible Box Layout Module, makes it easier to design flexible responsive layout structure without using float or positioning. Use of flexbox ensures that elements behave predictably when the page layout must accommodate different screen sizes and different display devices

It allows you to control the layout in a parent container. It offers some useful settings, which allow you to control the alignment of the items and to distribute the extra space. Flexbox is one-dimensional. That means it lays out its items in one dimension - either horizontally or vertically.

Benefits of CSS3 FlexBox

• For many applications, the flexible box model provides an improvement over the block model in that it does not use floats
• A “new” way of looking at responsive layouts
• Makes “mobile first” layouts a breeze
• page content can be laid out in any direction (to the left, to the right, downwards or even upwards)
• bits of content can have their visual order reversed or rearranged
• items can “flex” their sizes to respond to the available space and can be aligned
• with respect to their container or each other
• offer space distribution between items in an interface and powerful alignment capabilities

Basic Components and Terminologies

The CSS Flexbox specification describes a layout with items (flex-items) inside a container (flex-container). These items can grow or shrink in width and/or height, according to the available container space. The items “flex” to fit the parent container in the best possible way.

Why Open Source Development Services are the Best Choice

The rise of open source software has led to some important changes in the tech world. Once upon a time, if you wanted to build an app or website, you’d contract with a development agency and pay big bucks for it. Today, we have more affordable options like the cheaper and more accessible open source model.

Thanks to this shift in paradigm, businesses can now develop their websites and apps at a fraction of the cost. The demand for open source software services has grown immensely in recent years, as businesses discover how much money they can save by using them instead of contracting third-party vendors to build their sites and apps from scratch.

Why should your business take advantage of these services?

Because they offer numerous benefits over traditional contracting agencies — including reduced costs, accelerated timelines, improved ROI, and Intuitive processes.

What is Open Source?

The term open source refers to any program whose source code is made available for use or modification as users or other developers see fit. Unlike proprietary software, open source software is computer software that is developed as a public, open collaboration and made freely available to the public.
