Imagine that you spent sleepless nights over a week working on your client’s website to figure out the errors that dismay site performance and enlarge file size working on previous versions of the Angular framework. One fine day you wake up (hardly sleep) exploring something that developers are waiting for such a long time and there is a new release update.
Yes, you heard it right. It was February 7, 2020, when the Angular 9 release date was decided by the community. Usually, an update is released in six months with minor improvements in the features, but this time it was after 3 long years we are seeing major changes with new features introduced simplifying the hectic life of developers so well.
Your journey of reading with us for the next couple of minutes are going to be full of excitement as we bring you the most discussed essential features introduced with the release of Angular 9 that will help developers to improve the productivity. Let’s explore!!!
1. Internationalization (i18n): The core feature all it signifies
Previously, developers had to create separate files for translating a text in different languages about their applications. The internationalization feature was present to some extent in the Angular 8 version but with the release of Angular 9, it has become a core feature of it. It was also found that creating separate files for different languages had a direct impact on performance as well.
Now, developers can happily generate standard code using Angular CLI helping them to create translator files in Angular application that further can be used for multiple languages. This improvement will help to build process 10x times faster during runtime.
2. The new face of CSS Handling
This was also one of the biggest challenges for developers in CSS styling. Earlier, when developers created a styling file that included competing for style definitions, all of a sudden, those styles would replace with each other. But with the IVY, the styles are now merged well in a predictive way.
3. Ivy compiler: All-new default rendering engine
One of the most satisfying updates that came from Angular 9 release was the Ivy compiler as the default rendering engine. The reason being it significantly reduces the size of applications as well as enables better debugging, enhanced CSS class & style binding, improved build errors & type checking, optimized testing. It also saw that the code generated is much easier to understand for a developer to work upon.
As a whole, it has reduced the code with lesser instructions and improves the performance of an application drastically.
4. The inclusion of Google Map & YouTube capabilities
Angular 9 release has seen two new components being added to integrate with your application.
The inclusion of Google Maps in the CDK family is an obvious thing due to its popularity and being the product of Google. Now, you can easily use the @angular/google-maps package with your application to start using it. This directly saves time for developers as they do not have to refer the complete guide for Google Map API now.
Even YouTube has also been largely used by organizations for their applications and website to share company videos, client testimonials, milestones, etc.
In that case, it would be interesting to see how well these components will become handy for the developers.
5. The Trio of new features – Go to Definition, TextMate grammar and NgModule
After the release of Angular 9, there are significant improvements we have seen so far.
New features like “Go to Definition” has been added for styleURLs (path arrays to styling files) and templateURL (HTML file path).
Another interesting feature introduced was TextMate grammar to easily highlight syntax for inline and external templates within Angular Template Syntax.
To simplify the hover tooltip type information and NgModule that acts as a decorator for the class module.
6. Large bundle files: Gotta reduce them all
In previous versions, developers experienced the heavy loading of files for a particular application that would take more time and reserve more space. But with the use of Ivy compilers, it uses a tree-shake method eliminating unnecessary coding lines to reduce the file size to the minimalistic level.
This has resulted in gaining 40% smaller bundle sizes than previous larger bundle sizes.
To be specific, small applications have also benefitted through the tree-shake method who never used any of the Angular features while the larger applications have been successful in reducing the bundle file sizes.
The ultimate results are experienced during runtime when the applications are being loaded at the maximum.
7. Default enabled: AOT (Ahead of Time)
The most crucial part for a developer is to run applications during build time and maintaining the overall performance of the application. But this was for the first time when AOT could be used even in dev-mode builds as well.
This all been possible due to Ivy’s new architecture that we are seeing the improvements in the compiler by 40% with a decrement in the overhead from 0.8x to 0.5x.
In a nutshell
Google-powered Angular framework has brought some of the promising features after a long time with major changes to its architecture and its build capability.
If you have not yet explored its hidden charm for your application’s performance, now is the right to get into the driver’s seat to take the complete advantage of the Angular 9 version released just a week ago.
