“The Angular framework is used by 25.1% of developers across the globe” – states a survey report published by the renowned portal Statista in 2020. As per this report, Angular is the third most favorite choice of developers worldwide. This framework is known for its technical goodies and frequent updates. Each updated version intends to harness the latest technological innovations and improving the Angular experience. The proactive Angular team recently released yet another updated version, Angular11. The Angular11 release date is November14, 2020, and this release has strengthened Angular app development further.
Angular11 aims at addressing the bug-issues
that have been raised by the community which ultimately intend to improve the
developers’ experience. 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.
