Furthermore, Angular11 ushers in a plethora of improvements, modifications, and deprecations for simplifying the developmental process. As such, every Angular App Development Company should be well versed with the prominent updates in Angular11.

This article will enlighten you about the new updates introduced in Angular11. So, get ready to embark on a journey into the world of Angular11.

The Notable Updates, Add-ons, Deprecations, and Modifications introduced inAngular11

Enhancements in Component Test Harnesses

Component test harnesses were initially introduced in the 9th update of Angular. It offered a sturdy and legible API surface that facilitated testing of Angular material. It enabled developers to interact with the components of Angular Material by making use of supported API during testing. However, this feature was only available for Angular Material so far. Angular11 has added harnesses for all the components. As a result, testing became much easier, and the developers now create sturdier test suites. Besides, Angular11 also introduces parallel functions, new APIs, and performance enhancements. The parallel function feature works with asynchronous actions during testing, as it allows developers to carry out several asynchronous interactions with components simultaneously. The manual change detection feature allows developers to disable the auto change detection mode while unit testing and gain a finer-grained access control of change detection.

Refurbished Hot Module Replacement (HMR) Mechanism

The existing mechanism of HMR (Hot Module Replacement), which enables Angular developers to replace modules without having to refresh the full browser, is refurbished in Angular11. Now, a CLI command is introduced so that the developers have to put so much lesser effort to configure HMR. To enable HMR, one simply needs to employ the ng serve command along with an hmr tag.

Operation Byelog Updates

Operation Byelog was one of the items when the Angular’s Roadmap was shared by the Angular team. The team’s objective was to put in lots of engineering efforts for triaging PRs and issues till they could clearly understand the needs of the huge community. Their initial intention of this goal was fulfilled with the release of Angular11. The reason is all issues have been triaged successfully in each one of the three existing monorepos. This will go on as a continual effort as new issues are reported. Moreover, all new issues that are reported will be triaged within a period of two weeks. This has minimized the size of the Angular backlog considerably. Additionally, this update has resolved some common concerns related to the router and forms.

Updates in Language Service Preview

The language service feature in Angular offers tools that ease out development and boost productivity as well. The erstwhile Language Service was based on View Engine. With Angular11, the Language Service is based on Ivy which is more robust and accurate as compared to the View Engine. After this update, the Language Service can accurately infer the generic sin templates as done by a TypeScript compiler.

Automatic Font-Inlining

Angular11 also introduces auto-inlining of fonts. This feature converts the icons and Google fonts to inline in the index HTML, each time the flag is set in angular.json under the build option. The fonts that are being linked and used with the app will be downloaded and inlined by the Angular CLI during compilation. For leveraging this update, you need to ensure the availability of connectivity while the build is running on CI. So, upgrade your apps to Angular11 for receiving this feature by default.

 Faster Builds

•   Support for TypeScript 3.9 has been dropped and Angular11 supports only TypeScript 4.0. This deprecation intends to accelerate builds.
•  The ngcc update procedure has become two to four times faster than before when dependencies are being installed.

Experimental Support for Webpack 5

Webpack is employed for compiling numerous files into one single file or bundle. Webpack5 is the most recent version, though not fully stable yet. But Angular11 offers experimental support for Webpack5 so that they can be used together for trying out new things. As per Angular11 release notes the Angular team intends to expand this experimental support once Webpack5 is stable, for achieving smaller bundles and speedier builds.

Migrating to ESLint

With Angular11, the use of the popular Angular linting tool TSLint and Codelyzer has been deprecated and TSLint is replaced by ESLint. The future versions won’t be providing default implementation to lint Angular projects and hence the Angular team advises migrating to ESLint. The team has devised a three-step migration process for moving to ESLint from TSLint. The steps are:

•   Adding relevant dependencies
•   Running the schematic convert-tslint-to-eslint on a project
•   Removing TSLint configuration and using only ESLint.

Other noteworthy Updates

·         The Angular roadmap is updated to keep the users informed about the on-going priorities. The team intends to put more effort so that developers can provide early feedback that can be included in the final release.

•   Modifications have been made in the builder phase reporting to enhance its usability.
•   The new CLI output updates, simplify creating logs and reading reports.
•   Angular11 introduces lazy loading with the help of named outlets which was not possible earlier.

Final Takeaway

Angular11 is loaded with groundbreaking enhancements and profitable add-ons. To reap its benefits all you need to do is update to this most recent version.

The top advantages of Angular9 Ivy: The future-generation Compiler!

 The Angular team has amazed the entire software fraternity by releasing updated versions at frequent intervals! This is indeed a dynamic move to eliminate the road-blocks encountered by Angular app developers, leverage the goodies of emerging technologies and, provide a rich UX to customers. Angular has as many as 10 enhanced versions to its credit! Amongst these, Angular9 is one of the versions that offer multifarious breaking changes. Out of all these enhancements, the new Ivy Compiler in Angular’s V9 has stolen the show. Angular9 Ivy comes with unbeatable features that promise to make your app smaller and swifter.  This article talks about the advantages of the Ivy Compiler of Angular9 and its crucial role in Angular app Development.

Ivy Compiler of V9 in a nutshell

Ivy refers to Angular’s future-generation compiling and rendering pipeline. With the introduction of Angular9 Ivy, now the newer version of the compiler and the runtime instructions are employed by default in place of the older one called View engine.  This Ivy Compiler comes with numerous advantages for an Angular app Development Company.

Top Advantages of the Ivy Compiler in Angular9

Given below are the key advantages of the Ivy Compiler in Angular’s V9.

Default AOT Compilation: Quicker build times

In Angular’s previous versions, the developers preferred JIT compiler as the AOT compiler used to be very slow. However, the scenario has changed with the advent of Angular9 Ivy that enables the Ahead of Time (AOT) Compiler by default. The novel architecture of Ivy has worked wonders in improving the performance of the AOT Compiler. A compiler’s performance is measured based on the app’s overhead on the top of a plain TypeScript Compilation. Owing to Ivy, Angular’s AOT Compiler now performs approximately 40% better than it did earlier; as the overhead has reduced to 0.5X from 0.8X in the Angular documentation app. Thereby, the build times became quicker, proving to be a sigh of relief for the Angular app developers.

Reduction of bundle size

Unlike the earlier compiler View Engine, Ivy employs the tree-shaking technique to get rid of the unused code from applications. This leads to lesser code generation for each of the Angular components, thereby reducing the bundle size. Reduction in bundle sizes improves the app’s performance and proves beneficial to large applications having numerous components, as well as small applications that do not use too many Angular features. 

Lazy Loading

Ivy enables the lazy loading of any component. Thereafter, these components are dynamically rendered without the need for routing or an Angular module. Also, the libraries used by the lazy-loaded components are bundled to form lazy-loaded chunks.

Better manipulation of styles

Ivy has simplified style-handling and merges them predictably. Earlier the bindings were dependant on the last evaluation and the timing when a change was made to these expressions. Now, there is a clear and consistent order denoting specific styles as per their precedence, instead of timing.

Multiple language support via a single app bundle

Owing to Ivy, the app can support various languages using a single app bundle with one hostname. Some additional set-up may be required though.

Easier debugging 

The introduction of Ivy has ushered in more tools for debugging apps. To cite an example, the new “ng” object is available for debugging which enables the developers to obtain access to the directives, components, etc.

Speedy Testing

Thanks to Ivy, the application-testing speed has gone up by 40% to 50%. The reason is a revamped “TestBed” has been implemented which recompiles components used between test- cycles only if that component was manually overridden.

Added provider scopes

The new provider scopes “any” and “platform” have been introduced by the Ivy version of Angular. Provider scope “any” shares a provider for each module injector while “platform” scope can be shared across different Angular apps for the same document.

Better Internationalization

Internationalization refers to Angular’s existing feature which allows you to architect highly optimized apps as per the location. In Ivy, The quicker build-times are quicker due to pushing of build time substitutions later in the process, which makes this feature work much faster than before.

Better Type Checking

The Ivy Compiler is capable of checking more types of an application and applying more strict rules. Apart from the default type checks, there are some additional ones too. For instance, activating the flag “fullTemplateTypeCheck” signals the compiler to check all the aspects within the template, and activating the flag “strictTemplates” makes the compiler apply the strictest Type System rules available for type-checking. This functionality enables detecting bugs in the earlier stages of the developmental cycle itself.

Stronger Safety

In comparison to the erstwhile View Engine, Ivy is far more efficient in offering more safety. Furthermore, error messages become easier to read using Ivy.

Final Verdict

Thus, the Ivy Compiler in Angular’sV9, not only makes the Angular apps smaller, simpler and swifter but also gifts the Angular framework with a plethora of advantages. No wonder it is considered to be one of the most disruptive add-ons. Therefore, adopting this novel feature will indeed be a strategic move for any enterprise.
