Angular 14 All the Important Features and Updates

 


Angular is a typescript-based web application framework and is Google’s brilliant creation. It has released its latest version which is Angular 14. It has arrived with stand-alone components, promising to streamline application development by reducing the need for angular modules.

It is believed to be the most systematic pre-planned upgrade by Angular. It has released new features which include CLI auto-completion, typed reactive forms, stand-alone components, directives, pipes, and enhanced template diagnostics.

Stand-Alone Components:

The standalone component is a new feature that lets you create your components and use them anywhere in the app. The biggest advantage of standalone components is that they are easier to customize than other types of components.

You can create these kinds of components using the @Component annotation, which tells angular how to build this kind of component when you include it in the app. Here’s an example:

import {Component} from ‘@angular/core’;

import {AppComponent} from ‘./app.component’;

@Component({ selector: demo-app’, template: `<h1>Hello World!</h1>`}) export class AppComponent {}

Strictly Typed Forms:

In Angular 14, you can now use TypeScript to enforce a strict form of types on the forms. This means that each field will be checked against its type when it is submitted or validated, which makes it easier to make sure that the forms are not invalid.

Learn Django Workflow And Architecture

 

Django is a free and open source web application framework written in Python. A framework is nothing over a group of modules that create development easier. They're sorted along, and permit you to make applications or websites from associate existing supply, rather than from scratch.

When you are building a website, you mostly would like the same set of components: how to handle user authentication (signing up, signing in, sign language out), a management panel for your web site, forms, how to transfer files, etc.

Frameworks exist to save lots of you from having to reinvent the wheel and to assist alleviate a number of the overhead once you’re building a replacement web site and Django framework is one in all them.

The official project web site describes Django as “a high-level Python net framework that encourages fast development and clean, pragmatic style. It takes care of lot of effort of net development, thus you'll be able to target writing your app with no need to reinvent the wheel. It’s free and open supply.”

Django offers an enormous assortment of modules that you'll be able to use on your own. Primarily, frameworks exist to save lots of developers tons of wasted time and headaches and Django isn't any totally different.

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:

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.
