Angular 8 was just released on May 2019, but it was originally planned to be released on March or April, it did not work out as planned. With the new release that has been made available, it is important to know what all has changed, so you can decide your approach to Angular 8. Since Angular 7 is going to be supported until April 2020, you can decide if it’s worth upgrading or not if Angular 7 already meets all your requirements.

Let’s us walk through all the new features presented in Angular 8

Ivy Renderer

For a long time, the Angular team has been talking about the new Ivy renderer that the team has been working on. The team has spoken as well as written about it on multiple occasions, we have not seen an official release. All that is about to change.

The Angular team has confirmed about the inclusion of the Ivy renderer in their opt-in preview. Many developers were hoping for a final release of Ivy but that is not what we are getting in this release. A preview is many times better than no view at all. Trying out the preview will allow you to see how well your current Angular applications work with the Ivy renderer.

If you are not that familiar with Ivy, it is something you should care about. If the user experience is important to you then definitely Ivy is something you should know. Although the framework has made huge improvements about the size as well as the runtime speed since the days of Angular 2, Angular apps often tend to be on the heavier side when it comes to filing size and memory usage.

Ivy attempts to change all of this when you compare with the current Angular View Engine, Ivy provides the following advantages

The code generated by the Angular compiler is now much easier to read and understand by humans.
Rebuild times have become significantly faster
Decreased payload size, so your browser will take less time to download and parse your Angular applications
Better Template Type Checking, so the developers can catch more errors at build time and prevent your users from encountering them at the runtime

Apart from all of this, the Angular applications aim to be fully compatible with the existing Angular applications, so ideally you will be able to get all the benefits of Ivy without changing your apps at all. There will be some bugs and hiccups though. That’s why it’s helpful to try and build your current Angular apps using Angular 8 and Ivy.

If you run into any errors, you can let the Angular team know so that they can either fix the issue or advise you on what to change to be Ivy compatible and ready. There are a couple of areas where Ivy is lacking- in particular for internationalization and Angular universal support are not fully compatible yet. So if your Angular app supports multiple languages and/or uses rendering on the server-side then don’t expect it to be ready to work with Ivy just yet.

One more drawback is that some users have encountered is the Angular Material. Apps that use Angular Material don’t seem to play well with Ivy, as of the latest Angular Beta, Please note this when experimenting with Angular 8 (Angular Material will be updated to work with Ivy eventually).

Outside of Ivy, there are a few changes to look forward to in Angular 8

Angular 8 Additional Changes

One of the most important changes that the Angular team describes as the

“Differential Loading of Modern JavaScript”.

It simply means that the new apps generated by Angular CLI will now contain separate bundles for Legacy JavaScript (ES5) and modern JavaScript (ES2015+). This is wonderful news because modern browsers with ES2015 support will be able to download smaller, more efficient app bundles that render and load faster than ever before.

The Angular team is also adding a backward-compatible mode to the Angular router which will make it easier to upgrade legacy Angular apps to modern Angular. In the right world, we all would have been able to upgrade or Angular 1.X apps to Angular 2+ right away.

In the real world, this doesn’t always happen. To this day there have been massive legacy Angular apps happily chugging away serving businesses and making users happy. They have not been upgraded for a simple reason, there is not much ROI in doing a complete rewrite.

The end is near for Angular 1.X. It is not going to see any development and will only be receiving security patches until the end of its long term support period until June 30, 2021. For the teams working on large Angular 1.X apps, the time to finally make the transition is now. (And the changes to the Angular router will make the transition smoother). The router updates will make it smoother in order to lazy load the parts of Angular 1.X apps inside a modern Angular app using $route APIs.

Angular 8 Support for Web Workers

A small but welcoming new feature in Angular 8 is that it has improved support for building web workers with the Angular CLI. For readers unfamiliar with web workers, they are an important innovation for front end web development that will make it possible to group CPU intensive work in a separate hardware thread. This is indeed great news for front-end developers because prior to web workers the applications were limited to using a single thread.

However there is one catch with web workers, the code that runs in a worker should not be in the same JavaScript file as the rest of your Angular application. It has to be separate. This tends to work poorly with tools such as the Angular CLI that wants to bundle up the JavaScript into fewer files as possible. The Improvements to Angular CLI’s web worker bundling in Angular 8 will get rid of this awkwardness and put you on the path to fully parallelized web workers.

The Angular CLI will also be getting another feature- opt-in usage sharings. This will provide you the opportunity to opt-in to sharing telemetry about your Angular CLI usage with the Angular team. This is the right approach taken by the Angular team.

Some of the development tools have been known to share telemetry on an opt-out basis. They do it by default until you tell them not to. Some even share telemetry about how you use the tools without giving them any way to opt-out of this sharing. Asking for your consent is the right approach followed by the Angular team. Many of us will happily share our usage details in order for the development of the platform.

Support for TypeScript

Finally, Angular 8 is going to include updates to the latest and greatest versions of Angular dependencies which already includes tools such as RxJS and TypeScript. This seems to be a tiny improvement but is a welcoming one. Keeping up with TypeScript is great because the TypeScript team always seems to pack in useful features into every release.

Although there should be nothing to stop you from manually upgrading to the latest version of TypeScript in your projects, it is great to see the Angular team is keeping up with what TypeScript has to offer and the new apps that are generated from Angular CLI will also use the latest version of TypeScript by default.

Conclusion

We have seen that the additions to Angular 8 are not huge outside Ivy. Although they have been nice to have, they are certainly not critical for most applications

With that in mind, you should upgrade to Angular 8 or stick with Angular 7. In nearly every case the answer is yes. You should consider upgrading to Angular 8, since there are not any large breaking changes, in most cases, your applications will work as-is without any changes. With the additions to enable differential loading, you shall notice performance gains for free.

AngularJS has been around for quite some time now and it has gained huge popularity in the Web development industry. The days of cluttered websites, broken links, as well as unresponsive websites, are gone. It is time to embrace the modern web development era. The websites that are faster, more responsive, interactive, and has been impeccably created. These days there have been a lot of variables that make a website efficient. The ways in which the website displays the data is of utmost importance. This is where JavaScript steps in.

There has been an invention of many web frameworks developed to solve computing and web designing problems. Over the years these frameworks grew and developed popularity among the audience. In this article, we are going to have a look at one such framework. It is the Angular JS framework.

AngularJS is an advanced Web development framework introduced by Google. The intent behind developing this framework is to simplify the process of web development. In Spite of the abundance of web development frameworks available in the market, web developers and owners prefer to use the AngularJS development services. In this article, we will familiarize you with the reasons behind the popularity of AngularJS technology. Here are 9 reasons why AngularJS is highly popular within the web development community.

1) Ease of Use:

AngularJS has been developed from the ground up and the developers have added some rich features that make it easy for developing web applications using the AngularJS framework. Web developers can create user-friendly websites by writing the least amount of code. There is absolutely no need for writing setters and getters for applying different data models. And since the integral part of the app code does not have any directives, it becomes easy for the team working on it parallelly to manage them. Code writing mitigations means saving a lot of time and development effort.

2) The MVC Architecture:

Most of the frameworks that are available in the market are able to develop a web application. But the biggest limitation of these kinds of frameworks is that they are unable to bifurcate them into the MVC architecture. MVC is the shortened form for Model View Controller. When you go for the AngularJS app development, you can make the most out of this feature. This is because it comes equipped with the potential to string or join the application code together. It saves a lot of time required for development and it reduces the app’s time to market.

3) Enhanced Community Support:

Since Google has developed AngularJS, it boasts of a large community of active developers around the world who are ready to solve all your doubt and queries, as well as help budding developers, implement their solutions into web applications. These developers have expertise in making improvements with the open source framework. They also organize regular conferences for Angular JS and invite IT companies from all over the world to know about the latest developments in the technology. Hence when it comes to finding web application development services for AngularJS, you shall never fall short of options.

4) Works on Client Side:

AngularJS is a Front end web development framework that can be used to generate the user interface for web applications or web pages. It works well on the client side. And hence it works on both the mobile as well as desktop devices. It is also versatile which means developers can use it to develop the front end of any kind of applications without making backend modifications. Developers can use it for developing any kind of web applications.

5) Offers Modularity in Coding:

Modularity is one of the prime reasons why AngularJS is popular among web developers. It allows and enables web developers to create multiple modules for a single web application. All these modules are dependent on one another and developers can easily combine them to create a single running application. AngularJS recognizes the need to create an additional module so that it can be combined with other developed application modules.

6) Comes with Filters:

AngularJS’s filters are of big help when it comes to transforming the stored data in AngularJS responsive designs. The AngularJS directory offers programmers and developers with different kinds of filters for numbers, lowercase, uppercase, currency, orderby, date, and much more. It also provides options to create a custom filter by registering a new filter factory.

7) Two-way Data Binding:

The two-way data binding functionality in AngularJS is quite good. As a part of the functionality, any changes that will happen to the application will have an effect on the user interface and vice versa. With AngularJS the user’s actions, as well as the module changes, happen simultaneously.

8) Easy Testing:

When it comes to the AngularJS framework, testing your angular application can be extremely easy. This is because it is easy to manipulate different parts of the application that are placed inside AngularJS. The module separation feature allows the developers to load the needed services as well as implement the automated testing with a lot of ease.

9) The SPA Features:

AngularJS is known for its Single Page Application implementation. AngularJS has been closely associated with the SPA. They also offer validation capacity. Which means that if the page makes use of the forms, the form controller can take note of their states. With the help of this data, the developers or programmers can change the conduct of the HTML elements in the user interface. AngularJS comes equipped with a built-in validator that helps to validate the HTML elements, it also helps in error handling. However, you are free to create your own validator. You can show error messages for the entire form or just for some selected fields, or for separate fields also.

The preceding points must have given you an ample amount of idea for why AngularJS is the most sought after web development application. When it comes to working along with web development using JavaScript framework, there’s nothing like AngularJs. Also, it is beneficial when it comes to making single page applications for businesses.

AngularJS (also written as Angular.js) was first originated by Misko Hevery and Adam Abrons in 2009. However, after the long years, it is now mainly maintained by Google. Being an open-source web application framework, It lets you use HTML as your template language. It also helps you extend its HTML syntax to express your application components clearly and succinctly to use it further.

AngularJS is a structural framework used for dynamic web applications, it helps greatly in creating and developing single-page applications. Using single-page HTML we can easily declare many dynamic views in the web-apps. In order to express and represent the components of your application precisely it stretches HTML’s syntax.

Since AngularJS is made up of the structural framework it provides you with a large choice of tools for designing today’s modern-day web applications. It is capable of automatically handling the JavaScript codes that suites each browser. Thus it can be said that applications written in AngularJS are cross-browser compliant.

Here are some of the important features of AngularJS are :

 Great MVC/MVVM design pattern As AngularJS framework is a cross-browser applicant it aims to provide you with both the development as well as testing by providing a framework client-side MVC (mobile-view-controller) and MVVM (model-view-ViewModel). It helps you segregate and signify the designed patterns into many sections. MVC is a concept of modern web applications. It helps designers to view and use each different segment as per their needs and creativity.

Built by Google Since AngularJS structural framework has been developed by a group of developers from Google and the community of individuals and corporations. It helps you make rich internet applications.

We can find this open-source language completely free. It was licensed under the  Apache license version 2.0. Its latest version available today is 1.2.21.

Since the framework is designed by Google it provides advantages to the developers in a larger context solving many of their difficulties.

Advantages of AngularJS

1. Data Binding

One of the features that helps you tackle the biggest challenge is data binding. It helps you do the automatic synchronization of data between the model and view components. It helps you eliminate the large part of the codes, making it much simpler and easier to read and understand.

2. HTML User Interface

AngularJS build the user interface using the HTML (HyperText Markup Language). The use of  HTML language, it provides us much simpler, easier and organized user interface. Instead of full complete sentences, we started using short tags. In comparison with JavaScript, HTML is less complicated and easy to work with.

3. Directives

These are the extended sets of inbuilt attributes using the HTML. The major function on these directives is that they enhance the functionality of HTML in the most basic way. This function of directives helps users make dynamic client-side applications. In AngularJS all the in-built directives begin with the prefix ‘ng’. Angular users can even make their own custom directives. For that, you’ll have to use the .directive function. Once the directive is created you can invoke and use its name as HTML element, attribute, class or comment.

4. Modules

In AngularJS number of modules defines the number of applications within the area of that module where all the different elements of the application exist. Filters – It helps you filter data for a fitting view. Using these filters you can change the data into an appropriate format of currency, date, time, etc. In order to carry out various different purposes, there is a number of other inbuilt filters in AngularJS. These filters will work exactly like the inbuilt filters in the application.

5. Simple Architecture

AngularJS provides our developers with simpler architecture with a bundle of advanced features to help your designs and projects. It easily manages your heavy web applications containing complex elements and components.

6. Minimal Code

The use of AngularJS reduces code in your applications.

7. Fewer Errors

Since AngularJS is an open-source structural framework you expect the number of errors or issues to be minimal.

8. Code Reusability

AngularJS provides its users the facility to reuse its code. It helps users save their time and energy from designing new code.

9. Directives

Marker on a DOM element such as attribute, element name, comment, CSS which attach to specific behavior.

10. Dependency Injection

AngularJS has a dependency injection mechanism for making applications develop, understand, and test.

11. Two Way Data Binding 

AngularJS helps you synchronize the data between the model and the view component. It will help you eliminate JavaScript code to keep your HTML data code in sync. AngularJS will automatically do that for you.

12. Templating

It is a plain HTML which is parsed by the browser into the DOM.

13. Testing Support

 With the use of AngularJS developers are free with the code of testing. JavaScript AngularJS supports both Unit Testing and Integration Testing.

14. Good for large and Complex Projects

Building large projects with the help of AngularJS is easy to develop.it most useful when multiple forms in the web application.

15. Faster Application Development

AngularJS is an extremely powerful javascript framework to develop web applications. The Process of custom web app development makes the more easy task for the enterprise.

Disadvantages of AngularJS

Along with the advantages each platform has its own disadvantages too.

Complicity in understanding

As the users are allowed to use different styles of coding it may complicate things, making your application complex and difficult to understand. Link and compilations are not spontaneous in case of specific cases.

Complicity

AngularJS is vast and complicated. As it offers multiple ways to accomplish your tasks it is hard to know which way is best for doing a particular task.

Poor Scalability

With poor scalability as the project grows AngularJS can be more problematic and difficult to understand and work with.

Security

 Since AngularJS runs on the JavaScript framework your application is not secured completely. In case your server stops supporting JavaScript the user would not be able to access the website and will only see the basic page. This doesn’t happen with plain HTML web.

Require more time for rendering

 Also because of the JavaScript framework if the user will overload the apps the browser may take extra time in rendering the websites and applications.
