AngularJS Version 7.2 is here – What’s new in Angular v8?

Check about AngularJS Version 7.2, 7.1 & 7.0 along with Angular v8 updates. What’s New in Angular 8? Google’s popular JavaScript framework Angular has released the latest version 7.2 recently.

What is Angular?

Angular is an open source web application framework for building dynamic applications. It is a JAVA based front end management platform for web development. It is maintained by Google and many other companies and individuals for helping in the development of single page applications and complex web pages. It has a model view controller architecture. This architecture can develop the user interface that will divide any application into three interconnected parts, Model, View, and controller. This helps in decoupling major components making code reuse very easy parallel development of the web pages.

Developed basically for desktop graphical user interfaces, it is now being used for designing web applications and mobile application development. The angular framework works by first reading hypertext markup language code (HTML page), which contains all the embedded tags and attributes. Angular reads those attributes as rules on how to process the input or output parts of the page represented by Javascript variables.

Why Angular is considered as an Important tool by Web developers?

Angular is considered one of the most important front-end management tool by web developers. Angular uses two-way data binding to synchronize the model and view represented by the code. This helps in improving the performance and testability of the program. The ability to build applications across various devices like mobile, desktop, native mobile and native desktop is one major advantage of using Angular. Its code reusability and ability to develop apps for all platforms is also another major plus point. It is coupled with Cordova or PhoneGap for mobile app development. Being widely used, Google has been working on the up-gradation of Angular 6 for some time and the development community has eagerly awaited for its release.

Latest AngularJS Versions

Let us see the changes brought about in the major release and then see the updates to it in the minor releases.

Angular 7.0 ( major release)

The new features and updates brought about in Angular 7 made it faster, easier to use and also provided more functionalities. But the main aim of the upgraded version was the ivy project, the complete rewrite of the core compiler code and runtime code to make the program faster, smaller and better. The Ivy project is not on a full scale out, the rumors about the release of this new Angular was quite impactful in the developer community during its release. There were a lot of other upgrades in Angular 7 from its previous version. These updates are listed below

  1. CLI prompts
  2. Angular material and CDK
  3. Angular elements
  4. Angular compiler
  5. Improved performance and accessibility
  6. Dependency updates

The very notable changes in version 7 were virtual scrolling, allowed the loading of data as and when the user scrolls down the app or page that is it uses lazy loading rather than loading everything at once. The drag and drop feature is also a very important change that is very useful for developers. It allows the user to simply drag and drop items where ever required with the use of sorting within a list.

The removal of reflect metadata from the production part was another major change that made the platform perform better, by reducing the size of the app. The development of the user interface is also made easier and comfortable for the developer by allowing the use of CSS, SASS, SCSS, etc. Support for Typescript 3.1 and RxJs 6.3.3. was also added in this version, making debugging of the code easier for developers while also improving the performance of the developed apps.

Angular 7.1 ( minor release)

Being the first minor release it was mainly focused on bug fixes to the major release with a few additions in features. The update had about 20 bug fixes with around 10 new features added to the program.

  1. A few main changes observed are mentioned below. A main new feature was added in this minor release, ‘pathParamsChange mode for runGuardsAndResolvers’, this, when executed, prevents the guards and resolvers of the compiler to neglect changes in optional parameters like matrix parameters and queries.
  2. The compiler can also assign an Invokefunctionexpr as pure now.
  3. Typing has now been added to public API guard for service workers.
  4. Regressions in the router had been fixed.

Angular 7.2 ( minor release)

This version had 3 beta releases before the actual version and was released before Christmas. This version included several bug fixes and a few new features. Including the bug fixes in the beta versions, it had around 16 fixes and 5 new features. The addition of support for Typescript 3.2 is one major feature in this new version. It has a lot of new additions for improving router capabilities. The addition of Navigation type for navigation is yet another major feature. When navigating back to a page that is managed by the Angular router, the whole object is restored. The source map is now more fine-grained, instead of taking one Boolean value as TRUE or FALSE it now generates special source maps which provide an object that can be configured to use only what is required of the scripts source map, styles source map, hidden source map or vendor source map. Optimization also takes an object now instead of a Boolean value. The scripts and styles can be configured to true or false irrespective of the other with the help of the object. A flag override warning function was also added to warn the user when the same flag is repeated several times in the same command. A new verbose flag is added to display the details of what is exactly going on and thus helps in the debugging of potential issues.

Angular reads those attributes as rules on how to process the input or output parts of the page represented by Javascript variables. Angularjs is considered one of the most important front-end management tool by web developers. It is also the front -end part of the MEAN stack development platform out of which NODE.js and Angular js are the most widely used components. Angular uses two-way data binding to synchronize the model and view represented by the code. This helps in improving the performance and testability of the program.

Advantages of Using AngularJS & it’s Version 7

The ability to build applications across various devices like mobile, desktop, native mobile and native desktop is one major advantage of using Angular. Its code reusability and ability to develop apps for all platforms is also another major plus point. Being widely used, Google has been working on the up-gradation of Angular 6 for some time and the development community has eagerly awaited for its release. Although all the features spread by the rumors are all not available in the new version of Angular, Angular 7 has been very much of an improvement from its previous versions.

New features introduced in Angular 7

The main aim of the new upgraded software was the ivy project, the complete rewrite of the core compiler code and runtime code to make the program faster, smaller and better. The Ivy project is not on a full scale out, the rumors about the release of this new better Angular was quite impactful in the developer community. There are a lot of other upgrades in Angular 7 from its previous version. These Angular 7 features & updates are listed below-

  1. CLI Prompts
  2. Angular Material and the CDK
  3. Angular Elements
  4. Compiler
  5. Improved Performance and Accessibility
  6. Dependency Updates
  7. Application Performance
  8. Virtual Scrolling
  9. Drag & Drop
  10. Better Accessibility of Selects
  11. Partner Launches

Angular 7 Features explained

The updates to the command line interface (CLI) in the new angular prompts common commands used to help developers. This new CLI also asks if routing is to be added when and where possible. It also allows the use of different style sheets and lets the developer select between CSS, SASS, SCSS. These prompts have been added to Schematics, all package publishing schematics benefit from the prompts. The schematic CLI lets you tell the Angular compiler which prompts should be executed.

Update:-

The new updates in the Angular Code development kit are very useful for decreasing the load on the server and increases the performance highly. As many mobile applications require dynamic loading of data, Angular has added the new virtual scrolling module. The dynamic loading and unloading of data into parts of the virtual DOM ( document object model) help in improving the performance greatly. The drag and drop feature which was also part of the update is also amazing. It lets the user simply drag and drop items where ever required and this is backed up by sorting between a list. This new CDK includes drag handlers, drop handlers, automatic rendering for the changed items. If the animation for the drag and drop function is not likable, it can be overridden by custom animation.  

The application performance was the target for Google while developing the new Angular, it has successfully been made faster than previous versions. The upgrade time for applications is very less almost 10 minutes lesser. With virtual scrolling and new CDK module, the applications run faster than ever. Not only is the size of the program made smaller, but the size of developed applications is also smaller. This was made sure by removing reflect metadata from the production part as it was required for only the development stage.

The updated dependencies for supporting components has made AngularJS as the best development tool for the current generation. It now supports Typescript 3.1, while Angular usually lags with its support for typescript this time Google has made sure to keep up this time. Angular 7 also supports RxJs 6.3.3 which is the latest version available, making debugging easier for developers while also providing a performance boost. Node 10 is also supported in Angular 7.

New Compiler

The new compiler and the new elements pack make Angular better than ever with all the advantages it already had. These new compilers also provide an amazing 8 phase compilation which helps in reducing app sizes by almost 2 times. The new elements and compiler allow the applications to reduce bundle sizes by almost 90 percent. The ivy release by Angular team is not been spoken about because it is still being in the development stage. But from all the bloggers talking about it, there should be a Beta release when version 7 is existent and a full-fledged model released with the version 8 of Angular.

The updating process to Angular 7 is also not so tough. It is very fast to update and no changes are required to the existing programs before updating. The prerequisites are not so hard to satisfy if you are running apps using Angular 6 then all that is required is to update RxJs to its latest version 6.0 and running a one-line command updates Angular to its latest version Angular 7.

Meanwhile, Angular 7 is the best solution for application and web development available in the market with all its upgraded features and performance improvements.

Android Js Development

WHY DEVELOPERS AND COMPANIES CHOOSE ANGULAR?

If you are unfamiliar with JavaScript and its functionality, the first thing that is due to strike your attention is what does Angular actually mean. For this, we are not gonna consult Google or Wikipedia because the only thing that they will do is confuse you. You will be left wondering what you just read. On the other hand, a programmer will read it and say, ‘oh that’s a perfect definition’. But it serves a little propose because definitions should also be meant for people who are unknown to it. A slightly easier definition is:

Android Js Development is a JavaScript MVC framework created by Google to build properly architecture and maintainable web applications.

The Android Js Development JavaScript holds an edge over other frameworks in many ways which will be discussed later on in the article. On the recent times, it has gained a lot of popularity because of its specifications. The closest to it is ReactJS. Alas, it holds an advantage over it also. Earlier, it was known as Angular 2.0. But 2.0 is dropped in the recent times and the name now stands at Angular.

So, here are some reasons why developers and companies choose angular over other frameworks. Or you can call it the benefits of using Angular over other frameworks:

Popular client-side framework:

Just about two-three years ago, ReactJS ruled over the market. There wasn’t even a competitor to it who could even come close. But thanks to the spectacular features of Angular, not only has Angular came close but also surpassed it. Actually, ReactJS is more like a library than a framework. And Angular is the most appropriate one for the job. For any framework to be successful, it should be created keeping in mind the requirements of the user. The end product would be used by the user. Any framework cannot be successful if it is not user-friendly. Android Js Development matches this requirement with ease.

Fewer lines of code:

Everyone wants to have a cut on the no. of lines he/she is writing. A fewer line of code means a decrease in the amount of code to deal with. You as a user would always prefer a code that is short and good rather than a long one. Like the audience of news channel just want a short but crisp show. Same is the case here. The text must be easy to understand and should be of only a few lines.

Easy to understand HTML codes:

The declaration of various functions in the code is very easy in Android Js Development. The codes are written in a language such that their readability becomes fairly easy for even a non-tech guy who doesn’t have any experience in this field. Gone are the days when the codes were written which could only be understood by the experts in the area. The new trend is to design your code in accordance with the beginners in this field who doesn’t have the slightest of ideas about it.

Simple to unit test:

The testing of your code becomes pretty easy in the Android Js Development. This is another advantage which Android Js Development holds over ReactJS. You can test your code on various parameters and present your code in the best way possible towards your employer. An error-free piece of code is liked by everyone. This includes employers as well because their job is split. They no longer need to test the code on their own.

Makes HTML more expressive: Another key factor which is responsible for why developers and companies choose Angular over other forms of frameworks lies in the fact that they make HTML more expressive. This is in the way of if conditions, for loops and data binding. Using the if conditions and for loops in your code will surely help in reducing the size of your codes. A relatively shorter piece of code is more preferred to a long one. It resists writing a single piece of code multiple times. This is possible only because of the if conditions and for loops.

Single page application:

Perhaps the most significant and prominent reason why developers and companies use Android Js Development over other forms of frameworks is that it is a single page application. Unlike the older versions, the new ones are more like a single page application. Earlier, it was the case that you click on an app and wait till the tab opens. This can take a few nanoseconds to a few seconds and in the same way to several minutes. This just exhausts one out. While in this version, it is more like a single page. When you click on a tab, it opens immediately as if it was just in front of our eyes. This is a significant feature that Angular holds over other frameworks.

Mobile optimization:

The generation of ours would be known as a generation of mobiles in the coming years. Everyone is busy with their mobile phones. You are very lucky to find a single person who is not carrying one. So, to move shoulder to shoulder in this world, the very important thing that is needed in a framework is mobile optimization. And in this regard also, Android Js Development stands a mile apart from other frameworks. It can be used to develop both native and hybrid mobile applications. Both these applications have already been discussed in the previous articles. So, this is how important Angular process to be in the long run and hence is preferred by developers and companies.

Is built with speed in mind:

A significant quality that is expected out of Angular is speed. A framework lacking in the speed department is of little use to the user and he/she will gradually get irritated due to it. Android Js Development is by far the most powerful framework in terms of speed. This is a major reason why developers and companies choose Angular over other forms of frameworks.

In this article, we have listed the various benefits related to Angular and why it should be preferred over other frameworks. Another key advantage that it holds is that it is based on business logic and can prove to be a vital source for you.
