Angular 8 – What are the new improvements and features

Do you know the name of Misko Hevery? If then let us tell you. Misko Hevery is the founder of AngularJS. He formed a framework to manage the issues of HTML while getting the best part of other libraries. The inception of Angular was a great implementation due to its wide array of features and this made the found Hevery very popular among the web developers.

When the Angular was not available in the market, it was very complex to handle the big size package compared to other libraries and generally, developers were facing performance issues in the existing frameworks. This doesn’t mean that Angular was perfect in every job, there were also lots of issues discovered in this framework that created the barrier in its success. Angular syntax performed very well. Vue.js took over the Angular while the loop system named chaotic digest restricted and limited its performance. 

The first version of AngularJS came into existence in 2009 and it was the year that made the base of today’s front-end app development. Since its inception, it has gone through lots of new improvements and adjustments. If you are looking for one of the best single page application development frameworks then Angular can be the best solution for you.

They have initiated the major launches as NativeScript for developing native mobile applications with Angular, StackBlitz integrated IDE, and Angular console allows you to run Angular functions.

There are plenty of new features added to the Angular 8 to know these features let’s go ahead know the latest features of Angular 8:

• TypeScript 3.4

Angular 8 offers support for TypeScript 3.4 and it is essential to execute your Angular 8 project. Therefore, you need to update your TypeScript version to 3.4. An incremental flag is introduced in TypeScript 3.4. This new flag tells TypeScript to spare all project graph information from the last run.

Whenever the TypeScript enters with the new flag incremental, it will utilize that required information in order to find out the best budget-friendly method to make the required changes to your project.

• Support for New Architect API/ Builders

With the new launch of Angular, it’s CLI (Command Line Interface) enables to access and use the latest version of the builders which is further termed as Architect API. For performing the different operations such as e2e, lint, test, server and build it used Builder API.

• Build web workers with the CLI

With the new version of Angular, it has become easier to manage CPU-intensive jobs in the applications. Angular 8 CLI incorporates a new schematic that is utilized with the ng generate command to build and upgrade the required project files to integrate a new web worker. The updated files include an initial or we can say a basic template for the newly added web worker. In this manner, there will be no need to worry more about boilerplate syntax. Additionally, focus on the coding you want to execute in the backend.

• Deprecated Features and APIs

Angular is perfect in maintaining a balance between innovation and stability and to make it done they have replaced or deleted some APIs and features in this manner, allowing Angular to make the changes in the platform itself, changing dependencies and remain updated with the best and new practices.

To make this shifting successful and smooth they decreased features and APIs for some time before deleting them which offers required time to developers to upgrade their app with the best practices and latest APIs.

• Support SVG Template

Angular 8 also supports lots of template features along with a file extension SVG. As a template in place of an HTML, you can use this file extension SVG. However, there may be a question in your mind that why replace an HTML file with SVG file extension as a template. There are lots of reasons for using SVG:

• It helps you bind in the same way as HTML templates.
• It can be used as a directive.
• It can be used as a result.

• Use Analytics Data

Angular CLI in Angular 8 collects use data analytics, it helps developers in prioritizing the features and enhancements. There, whenever you update the CLI ventures, it will automatically opt-in with the alternative known as nd analytics. When you apply this world-wide, then it will gather some information like RAM size, operating system, the flag used, the command used CPU count, errors with the data and run time to the angular team for upgrade and enhancement motive in the upcoming releases.

• Workspace and builder and APIs

Maybe you don’t consider it as a feature because these are common and available in all projects. Angular 8 also has various new APIs that enables developers to create a custom build. Additionally, it permits deployment commands by the hooks into the familiar ng build, ng run commands and ng test. With lots of other new APIs, you can work the workspace mentioned in Angular.json file, it will decrease the amount of manual manipulation and help you configure your project perfectly.

• Lazy Loading

It is based on the methods of Angular Routing because lazy loading decreases the sizes of large files. In the old versions of Angular, the property @loadChildren used by the route configuration permits a string and in case there was any typing error in the code, wrong module name.

Angular would not take it incorrectly and allow the value as a string until you try creating it. Therefore, to resolve that they have integrated backend in router configuration for dynamic imports. For lazy loading, it allows the usage of import statement and this will be focused on webpack, IDE, etc. 

In this way, if you are a new editor then it becomes easier to understand the syntax and find out the errors and you will not be required to wait for build time to find out the errors.

• Brazel and lvy availability

With the release of the new version of Angular 8, you have a preview variant of lvy for testing. If we talk about the new build system then it is Bazel and if we talk about new rendering engine than it is lvy. Both of these advantageous features are available to use with Angular 8. lvy is a new runtime or compiler and Angular 8 is the first version to launch lvy officially. It is a code name offered to the new-generation rendering pipeline and compilation. lvy is introduced with the motive to create faster and smaller app bundles.

Now come to Bazel. It is an open-source tool used to build and test broadly at Google. The Angular team is rapidly working to add Bazel into the modern toolset of Angular. It will assist developers to run faster builds on big projects.

Benefits of Bazel are as follows:

• For lazy loading modules it helps in dynamic imports.
• The incremental build and tests.
• On the build farms it has a possibility for remote builds and cache.
• You can create your frontends and backends with a same tool.

Conclusion

After looking at all above features, we can say that choosing Angular 8 is a great deal that makes the developers job easy and faster. Angular 8 intended to meet the modern technological trends with the added features. With these advanced features Angular 8 has become more smoother and making it a better development framework.
