Angular 13: Noteworthy Add-
ons, Enhancements, and
Modifications!
The dynamic team of the popular typescript-based web framework,
Angular, has been known for its periodic updates to keep up with
changing times and emerging technologies. And, here’s another update
that has created a buzz in the technical world. Their latest update,

Angular 13, rolled out on 3rd November 2021; is one of their most
organized, pre-planned, and game-changing updates so far.
So, what’s new in angular13? Well, this post discusses all the
noteworthy add-ons, embellishments, improvements, deletions as well
as modifications. Let’s peek through the novel offerings of Angular 13!
Angular 13: Major Add-ons, Enhancements, and
Modifications

Ivy View Engine replaces the Legacy View engine
After the Angular team had rolled out multiple updated versions that
marked a transitioning phase to the Ivy View Engine, Angular 13 is now
100% Ivy. Angular has completely removed support for the legacy view
engine and supports only Ivy. The existing libraries will get migrated to
the “partial” compilation mode automatically and the metadata that
was earlier needed for the legacy View Engine will be removed. Angular
developers should switch from “enableIvy:false” to
“compilationMode:partial” to keep up with the update.

This update brings about speedier compilation as well as enhanced
productivity to Angular app development. Moreover, the Ivy approach
enables developers to write codes dynamically unlike the previous
versions, wherein the developers needed a boilerplate for code creation.
Using the previous versions, developers are required to inject
ComponentFactoryResolver into the constructor for creating
components. But, with V13, components can be created without having
to create an associated factory using
ViewContainerRef.createComponent.
Modifications in the APF (Angular Package Format)
The APF (Angular Package Format) defines the format and the
structure of the packages contained within the Angular framework. This
approach greatly helps in packaging third-party libraries in the web
development environment. Angular 13 comes with a new version of the
APF, a modernized and streamlined APF.
Modifications and add-ons
· Older output formats including View Engine-specific metadata, have
been eliminated which will minimize the maintenance expenses as well
as the complexity of the codebase.

· Libraries created using the updated APF will not need to use ngcc any
longer; resulting in a leaner package as well as quicker execution.
· The production of UMD bundles have been removed
· The new APF supports Node package Exports and as such, Angular
developers will no longer unknowingly rely on internal APIs that are
subject to change.
· It generates ES2020 output and Ivy partial compilation output
· The new APF makes use of the package exports using the sub-path
pattern feature from Node.js for displaying multiple available outputs
at each entry point.
Form and Router Enhancements
V13 comes with FormControlStatus, a new type for forms which is a
union type of all status strings possible concerning form controls. This
add-on brings about two more modifications — the type of
AbstractControlStatus changes to FormControlStatus and
StatusChanges now has Observable<FormControlStatus> instead of
Observable<any>.

V13 introduces a host of new functions that manage form validation like
addValidators, setValidators, hasValidators, removeValidators,
alongside their equivalent async versions — addAsyncValidators,
setAsyncValidators, hasAsyncValidators, and removeAsyncValidators.
Now let’s take a look at the router modifications. The earlier Angular
versions had an empty string to set the routerLink directive value to
zero and undefined; without any means for disabling the link’s
navigation. However, with Angular 13, you can entirely disable the
navigation, if you set the same values to routerLink directive. Another
add-on is Active Change, a new output for the RouterLink directive;
which is produced every time when a related link becomes either active
or inactive. Developers using V13 can use dynamic ESM import
statements as in this updated version; the load property that is a part of
the route definition is unable to accept string values.
Enhancements to Angular Material Components
The enhancements made to Angular Material Components include:
· The addition of a default role to the “table” and stepper updations
· Improved ARIA descriptions and Datepicker

· Better accessibility of matChipRemove and a sturdy focus option for
the slider
· The touch sizes of the radio buttons and checkboxes are now bigger
resulting in a smoother UX with higher contrast modes.
· The feature of accurately detecting fake mouse down events from the
screen readers employing FocusMonitor such that Angular applications
are able to correctly interpret the occurrence of focus or click events on
the screen.
Performance Improvements in Angular 13
· The usage of ergonomic code-splitting APIs and the practice of
breaking down the granular code at a component level has reduced the
load times considerably.
· ESBuild, a superfast JavaScript bundler, has helped in enhancing the
performance as well. It works with Terser for optimizing global scripts,
supports CSS source maps that allow optimized global CSS, and also
supports languages such as Vue, Svelte, and Elm that are used in other
frameworks.

· Owing to the new enhanced Angular CLI, the framework currently
supports persistent build-cache by default — build outcomes are cached
on the disk. Consequently, the speed of Angular app development
accelerates by 68% as compared to the existing speed.
· In V13, the opt-in feature is enabled by default
· There are no Angular traits such as Directive, Component, Pipe,
NgModule decorators, Injectable, etc. in the incremental builds
performance.
Support for IE11 removed
The Angular team has removed support for IE11 (Internet Explorer11)
in the latest version Angular13, based on customer feedback, to make it
future-ready. As a result, the entire infrastructure concerning IE11 —
build passes, CSS code paths, polyfills, special JS, etc. — will be
eliminated.
Advantages
· Angular can now enjoy the benefits of native web APIs and also
leverage the features of new-age browsers — web animations and CSS
variables.

· Angular applications built in Angular 13 will have smaller-sized
bundles and load faster as code paths and IE-specific polyfills can be
removed.
· It eliminated the requirement for differential loading.
The build infrastructure and enhanced APIs will prove beneficial
to Angular app developers, whereas the end-users will enjoy speedier
load times as well as an improved UX.
However, this update will affect organizations that still use Internet
Explorer 11 and have not yet migrated to modern browsers like
Microsoft Edge. For migrating your project to Angular 13, you have to
run the ng update — this will automatically drop the IE-specific polyfills
and minimize the bundle size during migration. The existing Angular
development projects that still need the support for IE11, can continue
using Angular 12, which will be supported till November 2022.
Other Noteworthy Add-ons and Enhancements in Angular 13
· The introduction of TypeScript 4.4 allows users to access the multiple
languages functionality while working on it. This feature was absent in
the previous Typescript versions.

· Now in-built validators like max,min, and minLength can be
dynamically enabled or disabled.
· The support for inlining Adobe Fonts has been added in Angular 13,
just as inlining Google font support was added during the Angular11
update. Inlining fonts are responsible for speeding up the FCP (First
Conceptual Performance) and this improves the web performance
substantially.
· Angular Developers can leverage the benefits of the updated RxJS7.4
for developing new projects employing the new ‘ng’ command. The
Angular projects that are in RxJS V6.x, are to be manually updated with
the help of the command npm install rjs@7.4.
· The TestBed segment is now an improved one that functions
impeccably to tear down test modules and environments after every
test. The DOM gets cleaned by default after each test. So, developers
can expect tests that are lesser memory-intensive, have a lower amount
of interdependency, are more optimized, and get executed much faster.
Bottomline:
I hope my post has provided you with comprehensive insights on the
most significant updates that influence Angular app development.
