Angular 10: Learn about Features, Updates, Performance and more

Angular 10 is the latest version of one of the most popular frameworks for developing visually attractive front-end web apps. As of now, its beta version has only been released in the market on the 24th of June, 2020. Then there is a huge possibility that its final release may roll out any time soon. The latest release of Angular 10 is highly focused on the ecosystem and quality tools rather than introducing new features. It showcases that the newest release consists of a majority of deprecation and upgrades.

Angular 10 Learn about Features Updates Performance and more

So let’s have a look at what features and updates are Angular 10 providing to the web app developers:

 

  1. Optional Stricter Settings:

There is a provision of a stricter project setup with Angular 10. One can create a new workspace using ng new.

 ng new-strict

Once this flag is on, this allows the framework to start a new project using some new settings. These settings support in improving maintainability and make the CLI perform advanced optimizations on the app. Also, it became easier to catch bugs beforehand. Among other benefits, this flag supports app configuration without any side effects to ensure more developed tree-shaking.

 

  1. Compiler Update:

A new compiler interface is added to the latest Angular 10 version in order to cover the actual ngtsc compiler. Other than this, Angular 10 witnessed the addition of name spans for method calls and property reads. Further, it gets Angular language service, Dependency data, and ng-content selectors to the metadata.

The procreation of an accurate cost period is also added to the Expression Binding of a micro syntax expression to Parsed Property. This helps in procreating the period to the template ASTs (Ivy and VE, both).

 

  1. Bug Fixes:

Several bug fixes have been done in the Angular 10. The elimination of the unaddressed examples of the range in the compiler to the migration occurred mistakes due to the symbol not existing. And the Terser In lining Bug as well.

 

  1. Resolver Returns Empty:

With this feature, you can get rid of navigation. The only thing you need to do is defining a resolver that can return empty. In case you want to continue with the navigation, and you need to update the resolver for some default value.

  1. Combining with Many Transition Files:

Angular 10 that comprises new features, allows developers to merge many files in just one go. Other than this, the developers can perform this file transaction through messaging functions.

  1. Generic with ModuleWithProviders

In Angular 10, it has become compulsory to use generic keywords with ModuleWithProviders. This feature has been added to make the ModuleWithProviders patterns operate with the rendering sequence and Ivy compiling.

  1. TSLint v6, TSLib 2.9, and Typescript 3.9:

Angular 10 comes with Typescript 3.9. The language develops on JavaScript with the syntax inclusion for annotations and type declarations. The Typescript compiler uses these type declarations to type-check the developers’ code. Consequently, a more clear, readable JavaScript spawns out that runs on several runtimes.

With Typescript, it became so easy to save files across editors, thanks to its great editing performance. Typescript 3.9 allows users to focus on important aspects like stability, polish, and performance. Rather than error-checking, the latest Angular version allows strengthening other activities like rapid fixes, accelerating the compiler, editing experience, and completions.

  1. Removals and Corrections:

Angular 10 witnesses a lot of corrections and removal from the team of Angular developers.

Likewise, ESM5 and FESM5 bundles are now not the part of the Angular Package Format that results in file size reduction of around 119 MB, if you choose to install Angular using package managers like npm or Yarn.

Furthermore, the latest Angular 10 version now did not provide support to some old browsers like Internet Explorer 9, 10, and Internet Explorer Mobile.

  1. Async Locking Timeout:

There are chances that the configuration of the Async Locking Timeout may take place. It could include support in the ngcc. Config.js file, for maintaining the retry delays and retry attempts in the AsyncLocker.

 

Other than this, an examination has also been conducted to monitor the timeout utilizing the ngcc.config.js file. That lowers the timeout and helps in preventing more maximized applications to the test.

  1. New Date Range Picker:

An all-new Date Range Picker is the part of the new Angular 10. Developers can use this feature by utilizing elements of both mat date range input and mat date range picker.

  1. Increased Community Support:

Angular enjoys a large developer community support from across the world. That proactively works to offer value for angular projects throughout their development. Other than the launch of Angular 10, the organization has revealed its plans of huge investment for extending the community in order to achieve feet of developing a better front-end development platform.

With constant community efforts, not only the development of a better toolset or framework will take place but also the chances of occurring issues will reduce to a greater extent. Not even this, the organization is looking forward to investing a huge amount for a precise working with the Angular development community.

  1. Boost in ngcc performance:

A boost in performance can be witnessed that is achieved by lowering the entry point’s size. Other than this, the implemented hiding of dependencies can be seen inside the entry point and much easier to read from there as compared to its computation every time.

Though, it was not the scene earlier. The ngcc doesn’t need processing, and analysis of the entry point files for computing dependencies might be done through ngcc. That takes more time for large node modules.

For a performance boost, the computation of base Path has been created lazily. Earlier, this process was adopted when the Finder was instantiated, but now it is done in the case of TargetedEntryPointFinder.

  1. Warnings on CommonJS Imports:

If your project has a dependency packed with CommonJS, it will possibly affect the loading speed of the application. Also, the functionalities will respond comparatively slower. But with the new Angular 10 framework, you get the benefit of warnings associated with dependencies packed with CommonJS.

How to update to Angular 10

You can update your currently installed Angular framework using the following command.

ng update @update/cli @angular/core

For more information, you can visit Github and go through the general release of Angular 10.

Conclusion:

The latest Angular version 10 is for mobile and web developers. They must update their present Angular framework with the latest release. It will let them be aware of the new features and updates of the most widely used front-end web framework. They can use it and experience how these changes affect the development.
