Angular 11 Updates – Lining Up For The Better

These days, businesses are aiming for a very successful internet presence. As a result, the demand for a solid web application development framework with cutting-edge technologies has never been greater. Every now and then, there is a significant development in the world of online and software development that disrupts the way people operate and usher in a new wave of technological improvements that indirectly benefits a wide range of industries. And one such technological framework is Angular and its recent Angular 11 updates! 

Angular, Google’s JavaScript (TypeScript) framework is the ideal solution for web application development, mobile app development, and desktop applications that make an indispensable difference. Angular 11 updates which were released on November 11 2020, along with other Angular frameworks have become a requisite part of every software product development service.

Let’s now take a closer look at Angular 11 updates, how we can lint, log, and inline fonts, and more!

Top Awesome Angular 11 Updates & Features:

Updates On Operation Byelog:

Operation Byelog is the first entity where the angular team concentrated on spending a substantial engineering effort, especially in triage problems and PRs, before providing a good understanding of the extensive needs of the group. Hence it can now be confirmed that the initial target is over!

The Angular team has finally triaged the issues in all three monorepos and is committed to triaging all new issues within 2 weeks after being reported. This approach has also addressed a few common issues in the router and forms. Hence all the problems can now be reviewed and this allows one to reduce the size of the Angular backlog and solve loads of problems. Like the cherry on the cake, another excellent piece of news is that the new features of Angular 11 have committed to paying special attention to their community and enhancing the way they accept contributions.


In the earlier versions of Angular, there was a question about future and next routes being exchanged for child routes when using the RouteReuseStrategy #shouldReuseRoute process. This issue was hence fixed in Angular 11 updates and also preserveQueryParams was discontinued. However, users will have to use queryParamsHandling = “preserve” instead of the same. 


Angular 11 updates have made changes to boost the typing of previously inaccessible validators and asyncValidators. The AbstractFormControl.parent class in the recent angular update contains a null that is included in the .parent type. Migration version 11 adds a non-null assertion operator whenever it is required. In earlier versions, the FormControl, FormGroup, and FormArray classes had async validators specified at the time of initialization. However, in the new edition, the status event is emitted into the statusChanges observable.

Faster Builds:

In this latest update of Angular 11, the Angular team dropped supporting typescript 3.9. Now, the new feature of Angular 11 in Angular 11 updates only supports Typescript 4.0 and also uses the Ngcc- Angular compiler. The main reason for this up-gradation is to speed up the builds. Apart from that the recent Angular update ensures much faster builds four times than the previous one. This implies that users would have to spend relatively less time waiting to complete builds and rebuilds.

Hire Angular developers from the best custom software development company that displays remarkable expertise in handling the latest Angular 11 features.

ESLint Updates:

The previous versions of angular had a default implementation for linting that is the client. For a long period of time, it was reportedly one of the most common linting tools. Angular 11 features have deprecated the use of TSLint and Codelyzer. The default implementation for Linting Angular projects will not be available anymore in the future update. Moreover, the angular team has recommended migration to ESLint and it has also been tested to ensure a smooth transition for Angular devs.

Webpack 5 Support:

A webpack aids you to incorporate as many documents as possible into a single bundle or single record. Version 5 of Webpack is the latest version that was launched a few months ago. Hence, In order to be stable, it also needs a particular period of time. Angular 11 features plans to direct this route and make it possible to create it faster with very persistent disc caching, and even smaller package sizes with cjs tree-shaking.

Note: We do need to remember that it is still in its experimental stage, hence do not use it in the production mode. One can experiment the same with the module federation.

In the future, webpack v5 will have a clear path for:

  • Faster builds and disk caching
  • Smaller bundles with cjs tree-shaking

To try out Webpack 5, add the following section to your package.json file.

“resolutions”: {

“webpack”: “5.4.0”


Note: Use yarn to test this, as npm does not work perfectly yet.

Improved Reporting & Logging:

This latest version of Angular also incorporates new improvements in such a manner that the reporting on the building stage is carried out during development. New improvements have also been made to the CLI, in order to make logs and reports that are generally easy to read.

Updated Hot Module Replacement Support (HMR) :

Hot Module Replacement is a mechanism that enables the replacement of modules without the  complete refresh of the browser. HMR for Angular is not an entirely new idea and developers were already able to use the same in all the previous versions. One of Angular 11’s updates and new features is that it presents HMR assistance with necessary configuration and code adjustments. This hence makes it the ideal solution for Angular to be included efficiently and a CLI command has been provided for the same. One can simply use the “ ng serve” command with an “hmr” tag to enable HMR. 

ng serve –hmr

Component Test Hardness:

Component Test Hardness was first introduced in Angular V9 which provided support APIs to interact with other components. Such APIs are capable of communicating with the components in a manner that is close to that of end-users, and tests may also separate themselves from the DOM changes.

However, at that period, only angular material was supported by this process. But with the most recent update of Angular 11, a Component harness is available for all components. This thus allows the developers to create more robust test suites. Nevertheless, by allowing developers to run several asynchronous interactions parallelly with the components, the parallel feature makes it easier to deal with asynchronous behavior in your tests. 

Updated Language Service Preview:

Previous angular versions used the View engine for the Language service. However, Angular 11 on the other hand offers a new Ivy-based language service that is more efficient and precise. Although this function is still being developed, it can behave similarly to the TypeScript compiler which can give you the best hands-down angular experience. Additionally, within your templates, it will be able to infer generic types just like the TypeScript compiler. 

Here is a snippet of the illustration of the iterable string form.

Other Significant Groundbreaking Changes:

  • Angular 11 changes are planned to deprecate Internet Explorer 9 and 10, as well as IE mobile support. It is no longer compatible with TypeScript 3.9.
  • The queryParams parameter has been removed from the router, and queryParamsHandling=preserve can now be used instead.
  • ICU expressions are type-checked for the second time.
  • The “undefined” for input typed “undefined” is not claimed by Async pipe.

Concluding Lines:

Angular 11 changes without a doubt is a solid platform with the best new features in demand. Developers have already noticed a wide array of notable changes in the current Angular 11 updates. However, more alterations and modifications are likely to occur over time. 

Well, if you’re looking forward to upgrading your projects to Angular 11, you need to run the following command in the terminal, ng update @angular/cli @angular/core.  Looking forward to the next versions of angular with more fascinating new features on the go to provide world-class mobile and custom web applications development.
