Angular 11 Vs Angular 12

Web and Mobile apps have become a significant element of our personal and professional lives. This remarkable change has helped several companies to invest in a better option to build apps, and Angular is one of them. It is a javascript structure coded in typescript. It was designed & developed by Google and helps to decouple an application from DOM control. It is the most preferred JavaScript Framework for its incredible highlights.

The incredible features help designers to make some rich, superior applications without any hassle. Angular released its latest stable version in May 2021, while the existing version, Angular 11, was launched in November 2020. In this blog, we are going to discuss the detailed comparison between Angular 11 vs. Angular 12. 

Key Features of Angular 11 

1. Advanced Hot Module Replacement Support

The Hot Module Replacement mechanism is an essential feature of Angular 11 that helps to replace the modules without a browser refresh. Angular 11 supports HMR with the desired configuration and includes the code that changes in Angular code appearing less ideal. With HMR styles, and formats are instantly updated into the running application without refreshing the complete page.  

2. Updates on Operation Byelog

The Angular community has contributed some crucial design changes to Operation Byelog. They have focused on the triaging issues, and PRs meeting user needs. With Angular 11, all the problems are successfully triaged in the three monorepos that proceed with the new problems. This interaction also helps with a couple of essential concerns as far as router and forms are concerned. The issues are triaged in about fourteen days from the date of the event, ultimately lowering the size of the Angular backlog. 

3. Automatic Inline of Fonts

Angular 11 offers automatic font inline that triggers each time client flag in the angular.json. Angular inline assists the Google Fonts to change over in a manner. The inline text styles are downloaded in the Angular CLI during compile time used to connect in the application. The features of Angular 11 exploit the default improvement for the build to run at whatever point the web is accessible. 

4. Component Test Harnesses

The Component Test Harnesses offers an incredible and clear API surface helping to test the Angular Material parts. It provides a way to deal with developers to speak with Angular Material components. This element was first introduced in Angular 9. The difference is Angular 11 accompanies an equal capacity, execution upgrades, and latest APIs. The manual change detection helps the developer with debilitating the programmed change recognition in unit tests. 

5. Updated Language Service Preview

The Angular Language Service gives the developer usefulness and fun inside the Angular environment. The current language organization relies upon the View Engine that offers meaningful and exact insight for developers. Angular 11 changes the norm to precisely infer non-exclusive ones in templates and layouts, similar to the TypeScript compiler. This element is developed, offering an impressive and precise language administration. 

6. Faster Builds

The presence of faster builds in Angular 11 has brought updates within crucial regions, Ngcc the Angular compiler. The Ngcc update measure is 4x quick with the goal that clients must invest less energy waiting for the forms. While profiling the Angular compiler, the Angular donor makes the Typescript compiler quicker to improve the Ngcc, setting up the environment for Typescript 4.1, which will get faster builds. 

Key Features of Angular 12

1. Ivy Everywhere

Amongst multiple deprecations in the Angular environment, the deprecation of the View Engine is undoubtedly the most important one present in Angular 12. This deprecation is removed in future significant releases too. The Ivy everywhere refers to the process that works towards combining the Angular ecosystem on Ivy. The developers use the View Engines, but the developers want to transition to Ivy instantly. 

2. Migrate from i18n message IDs

In the current scenario, diverse legacy message-id plans are being implemented in the i18n system. These inheritance message-ids are fragile as concerns can arise subject to whitespace and the getting sorted out organizations and ICU articulations. To fix this problem, the community is moving away from them. The latest standard message-id configuration is significantly more extreme as well as expected. In Angular version 11, new tasks are usually intended to use the unique message ids, and they have the tooling to move existing endeavors with current interpretations. This arrangement will lower the pointless interpretation invalidation and related retranslation cost in applications where interpretations don’t facilitate because of the whitespace changes, for example. 

3. Protractor: Planning for future

The future of the Protractor is now in the hands of the Angular team and the community. They are investigating the input shared within the RFC and figuring out the best future for Protractor. The group has planned to prohibit it in the latest tasks and, in light of everything, furnish alternatives with acclaimed outsider arrangements in the Angular CLI. The group has worked with Cypress, WebdriverIO, and TestCafe to help Angularjs Development Company get elective placements. 

4. Improvements in Styling

In Angular v12, Components offer support for inline Sass in the styles field. Angular CDK and Angular Material have enjoyed Sass’s new module system inside. If the application implements Angular CDK, it is crucial to change from node-sass to the sass npm package. The node-sass package no longer remains mindful of advanced feature additions to the Sass language. 

5. Deprecating Support for IE11

The evergreen platform of Angular recommends that it keeps up with the propelling web ecosystem. Removing support for legacy browsers licenses them to give modern arrangements and better guidance to designers and customers. The team has additionally included another deprecation warning message as another Angular 12 element.

6. Typescript 4.2

The support of Typescript 4.2 is an essential update of Angular 12.2. It was released with some remarkable features, and breaking changes impacted the Angular 12 developers. Some of the critical elements of Typescript 4.2 are modifications in tuple types, improvements for in operator, improved type alias, abstract construct signatures, and changes improvements to the compile process.

Wrapping Up:

Apart from the latest features, if we compare Angular 11 with Angular 12, we can see the changes in their core structures and other upgrades. Another critical difference is in TypeScript. Angular 11 is based on TypeScript 4.0, while Angular 12 is based on TypeScript 4.2. Furthermore, Angular 12 has removed support for IE11 browser and default strict mode in addition to HTTP improvements. When planning to build an application, reach out to the AngularJS development company to elaborate on this comparison.
