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.
