Google has recently
launched a new version of Angular, Angular 7 in October 2018. The new version
of the JavaScript framework comes with exciting updates and worth knowing
changes.
The recent version
has taken into account new features and tools as well as improvement in the
existing ones along with enhanced performance outcomes.
Being one of the
most preferred front-end frameworks for JavaScript, Angular 7 comes with useful
upgrades over its previous versions. The recent release spans the platform
entirely with significant tooling changes.
Let’s have a look
at the new features in Angular 7:
1. ng
Compiler: The newly introduced ng compiler reduces
the bundle sizes of the apps massively. The ng compiler is capable of
eight-phase rotating AOT (Ahead-of-Time) compilation which leads to the
reduction in the app size. The bundle size gets condensed by 95-99%.
2. CLI
Prompts: This is a life-saving feature for
developers who tend to forget routing or like activities. The new CLI prompts
you to add routing or take advantage of other in-built SCSS support. So, now if
you are running commands like ng new or ng add, you will not end up terminating
the command if you happen to forget routing. You can also select between
different stylesheet formats including CSS, SCSS and SAAS. The best part is its
ability to get customised.
3. Angular Do Bootstrap: ngDoBootstrap is a new lifecycle hook
added to Angular 7 along with an interface called DoBootstrap. It will be used
for bootstrapping the modules so that the hook will manage the entire life
cycle of the components by enabling to look into their crucial life moments.
4. Application
Performance: The good news is that the brand new
version of Angular 7 exhibits commendable performance as far as speed of apps
upgrade and framework is concerned. Secondly, Google deserves applauds as the
team has been able to correct a very common mistake that was present in the
previous versions.
It came into the
notice of Google team that app developers were using reflect-metadata in
production. However, it is only needed in the development phase. So, in Angular
7 this problem is fixed by eliminating the poly fills.ts file automatically.
Secondly, the new
version gives a chance to set up budgets for new apps using Bundle Budgets.
5. The Angular
Material CDK: The component dev kit has undergone
through minor updates in Material Design that mobile app developers must keep
in mind. New CDK includes features like Drag and Drop and Virtual Scrolling.
The drag-and-drop
feature now offers a more sophisticated way of creating drag and drop
interfaces. New module includes features like transferring items between lists,
placeholders, animations; custom drag handles, automatic rendering and touch
devices.
The new virtual
scrolling feature is beneficial for the developers with big scrollable lists.
The scrolling helps in loading and unloading elements from the DOM with a boost
in overall performance.
Conclusion
In a nutshell, it
can be said that Angular 7 is one of the most excellent versions of the
framework with crucial changes that increase the efficiency of app developers.
Google has contributed immensely to keep this framework up to date and meet the
requirements of modern-day developers. The Angular platform is better than ever
with an enhancement in the performance. Angular 7 is a useful tool available in
