The Angular team also frequently updates it with better features and functionalities just like the recent major update – Angular 6.

Wait, did you say update?

Umm, yes…

Ugg…not again!

Though the latest updates come with some amazing features, migrating your app to a newer version can be a daunting task.  As a top AngularJS development company, many clients have approached us to migrate their app from AngularJS (Angular 1.0) to newer versions as it was a pain in the neck for them.

Let’s face it. Migrating to a newer version was never easy. However, the Angular team with its new release – version 6.0 is making the update and migration easier. How? Let’s find out.

Easy Backward Compatibility to the New Angular Versions

The Angular team is looking to create an easy update and migration process for all its users. As a part of it, they have focused more on providing end-to-end developer experience and less on the framework in its latest Angular 6.0.

Stephen Fluin during Google I/O 2018 addressed, “Someday we want this version number to disappear so that we just talk about the new features, and then everyone automatically gets them. And one of the ways we see that vision coming true is by making the update process easier,”

Angular 6.0 will provide users with innovative features without disrupting the current framework. They call it ‘Stability + Innovation’.

Sounds like a utopian JavaScript world for every web app developer and owner, right?

But How Will They do it?

Updating has become a lot easier in Angular 6.0 and it is all because of a new CLI command called ng to update <package>. You just need to run the command ng update and give the package name. Then it will review the package.json and automatically recommend the updates to the application. The Angular team has already used it in Angular Material and RxJS. To understand how it works, let’s have a look at this example.

Here we run the command ng update @angular/core where @angular/core is one of the Angular packages of the project.  And the package JSON of @angular/core consists of a package group. So, when you update one of the packages in Angular, you are going to get all the associated packages at one place updated together. The team has also worked on providing updates to peer dependencies. So the ng update@core will provide you with all the latest framework packages and dependencies required, making the update and migration process easier.

Long Term Support for all Major Releases

Another breakthrough announcement made by the Angular team is that they will provide long-term support to all its major releases. Previously they announced LTS just for Angular v4 and v6. However, to make the updating process from one major release to next one easier, they have extended the long-term support to all the major release from v4 and above. All of the Angular releases are supported actively for 6 months and once the next major version is released, it enters the long-term support for another 12 months. The LST state of one major version initiates the day a new version is released (major released) and ends a year later with the release of another major version.

Even AngularJS, the first version of the framework will now be under LTS. Due to the fact that it is extremely stable and is still being used in many projects, the Angular team has been working to release version 1.7.0 which will enter a 3 years long-term support on July 1, 2018.

AngularJS schedule

• January 1 to June 30, 2018  – AngularJS 1.7 Active Development
• July 1, 2018 to June 30, 2021 – AngularJS 1.7 LTS Period

What Does it Mean for Web App Owners?

Angular has been the top choice of web app developers and owners when it comes to reliability and consistency. In fact, it has been used in numerous huge projects. It is also considered best for enterprise applications to manage millions of users and dollars. The ng update and LTS support will make it even better. It will allow you to stay with the technology for a long time, get updated features and easy migration without any hassle.

Let’s understand this new trend of the web app development industry and if it fits your business needs.

What is Micro Frontend?

Micro Frontend is the same concept as Microservices but for the frontend of the web app. The idea here is the same – to make small independent service work together for a large complex application.

The frontend of current web apps is built with single technology, by a single team and is developed altogether. This is known as “monolithic architecture”.

But in Micro Frontend the web apps are developed into modules to fulfill a specific business requirement that is owned by different teams. And each team end-to-end develops the feature, starting from the UI to backend to database.

(Monolithic Frontend VS Micro Frontend)

How are Startups Benefited from Micro Frontend?

There is no doubt micro frontend architecture provides substantial benefits to the business just like the microservice backend architecture.

Any business has to cope up with the changing trends and contemporary needs to excel. In order to modify or add any new feature to a monolithic frontend, it would require a huge change in the code-base.

Whereas micro frontend is proven to be highly scalable and can tackle various issues faced by the business. Here are few benefits of micro frontends that makes it perfect for start-ups.

Benefits of Various Technologies

Every other day a new JavaScript technology is invented and these are proliferating faster than a speeding bullet. And of course, we all are left to select one from the pool of options. That sometimes can be frustrating as every JavaScript technology has its own pros and cons. And while selecting a particular technology, we consider the minimum risk and max benefit. Here a micro frontend can help to use different technology for different services.

Highly Scalable and Upgrade

Because of its modular structure micro frontend is highly scalable when you need to grow the business. Even it is open to upgrading to the latest technology ranging from web, mobile, Internet of Things, wearables or simply to a newer framework.

Faster Development and Deployment

Since each service is developed to work independently by a different team, they can simultaneously develop and test each service without being interdependent. This results in faster development as well as deployment.

High Resilience

In Micro frontend web apps are distributed in small chunks of services starting from the UI to database that works independently. So, even if one feature faces the issue, it doesn’t affect the rest of the web app. And this feature makes it possible to recover from the error faster.

Better Maintenance

Instead of huge holistic codes, the code-base is distributed according to the feature and functionality and a specific team maintains them. This makes it easier to maintain the app.

Is Micro Frontend a Match for You?

Though micro frontend may seem to be an elixir for the trending business, before you migrate to it you need to consider few questions.

1. Do you have a growing user base that requires to scale the application?
2. Do your app needs independent functionalities and features with a micro-front end?
3. Is your app so huge that it is a pain in the neck to maintain it?
4. Is it required to use multiple technologies in your web app?

Conclusion:

The fact that makes Micro Frontends ideal for startups is that it makes your web app scalable and futureproof. Sooner or later, when the business grows or the business needs changes, you need to evolve with the change. And these small independent services of micro frontend makes it easy to cope up with the changes.

React

Unlike Angular, React is a JavaScript Library that focuses on “View” part of Model-View-Controller (MVC) development. React is a JavaScript library, not a framework. So, it does not provide a complete solution but instead, it easily interacts with different libraries.

React was built to create web apps that can render specific components rather than a full page refresh. This was made possible with the component-based architecture. Today it has extended the purview of possibilities and it is no longer just a library to build the user interface. Many top-notch projects like Facebook, Instagram, Coursera, Yahoo!, etc. are build using React.

Developed and Maintained by

React was developed by Facebook and even it manages the ongoing development and updates. Earlier it was under a BSD-derived license that raised issues related to patents and copyrights. But in 2017 Facebook re-licenced React under MIT.

Key Features

1.  Flexible
2.  Provides freedom
3. Virtual DOM
4.  Component-based
5.  Declarative
6.  One-way data flow

Popularity and Trends

2017 stats by GitHub shows, React Native is the top JavaScript technology project with the most number of contributors (8.8k) followed by Angular-CLI (7.4k) and Angular (6k).

(Image source- GitHub)

Stats on Built With shows 3% of Quantcast top 10k websites are built using React. While the entire internet consists of 174,100 active sites that are built using React.

(Image source- Built With)

The number of React’s repository on Github is an eye-popping 419,651.

When to Use React?

React is a Javascript library, not a framework. Thus, web app development using React provides you flexibility and freedom rather than confining you to a framework template. So, if you are looking for more flexibility and customization for your project then React is the most suitable for your needs. It is the right choice for most general app development such as productivity apps, single page apps, Progressive Web Apps, mobile apps using React Native, IOT apps with React for IoT and AR/VR apps using React for AR/VR.

Conclusion

React is a perfect technology for your project if you are looking for:

• Flexibility
• Freedom to build app in your own way
• Standardization doesn’t bother you
• Easy 3rd party integration
• Progressive Web Apps
• IOT apps
• AR/VR apps

Vue.js

Vue.js is a lightweight progressive framework for creating interactive user interfaces. It is the new player in the game that has been observing its competitors. Just like Angular and React, Vue.js serves similar functionality for building user interfaces for SPAs and other web apps. It provides React-like virtual DOM and can be easily integrated with other libraries too.

The cool part about Vue.js is that it was made adopting the virtues of Angular and React that makes this framework versatile, lightweight and easy to learn. Many multinational behemoths like Expedia, Nintendo and Alibaba are using Vue.js for their projects.

Developed and Maintained by

Vue.js was developed by Evan You, an ex-Google employee who worked on several Angular projects. Describing his thought on Vue.js he said, “I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight without all the extra concepts involved?” It is free from any copyright, patent or usage issue as it is MIT licensed.

Key Features of Vue.js

1.  Lightweight
2.  Easy integration with existing apps
3.  Effortless 3rd party integration
4.  Simple to understand and develop
5.  Versatile
6.  Blazing fast

Popularity and Trends

Vue.js beats Angular and React in the race of “Ten most forked projects” with 8.1k forks according to GitHub, Vue.js is followed by React Native with 8k forks.

Architecture

1.0 vs 2.0

Angularjs 2.0 entirely rewritten compare to 1.0 and it’s a significant structural change. There are few upgrade possibilities of 1.0 to 2.0 and most of the cases only suitable possible option are to rewrite the application in Angularjs 2.0.

2.0 vs 4.0

Though Angularjs 4.0 have under the hood changes over 2.0 and which make it faster and reduce file of generated code of component by 60%. Same generated code can be used for debugging and prod mode.

Javascript vs TypeScript

1.0 vs 2.0

Angularjs 1.0 application build on Javascript but Angular 2.0 comes with Typescripts which is a superset of Javascript which helps developers to write more structured and robust code. Along with Typescripts, developers can use Dart with 2.0.

2.0 vs 4.0

Latest Angular version 4.0 compatible with Typescript 2.1 and 2.2 which improve type checking throughout the application.

Component-based UI

1.0 vs 2.0

Angularjs 2.0 changed to component based UI and dropped controller concept which was in Angular 1.0. As a developer intent, we can split application features into various components and call required UI. Which increase reusability and flexibility over 1.0. If you worked on reactjs then might aware of component-based structure already.

Mobile Support

1.0 vs 2.0

With Angular 2.0, they accomplish a goal to make native applications like React Native. Angular 2.0 have application layer and the rendering layer. So, a separate view can be rendered in runtime by associating with a required component. based on need

SEO Friendly

1.0 vs 2.0

Search engine friendliness was a major issue with Angular 1.0 while developing single page applications but in angularjs 2.0 they eliminate this bottleneck. With Angular Universal, now it’s possible to build single page application SEO friendly by rendering plain HTML at the server side.

Related read: Angular 4 is coming in 2017 – No Angular 3, why it does not matter?

Additional new features in Angular 4.0

• Angular Universal was a community driven project but now adopted by the Angular team. It’s great news and opens a new dimension to build powerful SPA yet 100% SEO friendly.
• New service to easily get or update meta tags
• New Validators for valid email
• Animation has an own package and pulled out from @angular/core which reduces code if your production package not using Animation.
• Better Debugging with Source Maps for Templates

Conclusion

If you are planning a new project then you must start with Angular 4.0 with Angular Universal as tech stack and which definitely provide the scalable, secure and flexible path.
If you are planning an upgrade from Angular 2.0 to Angular 4.0 then it will be easy and developer should do only if the application demands it.
I feel application which was built on Angular 1.0 demands future upgrade with Angular 4.0. However, still, you should check that what kind of bottlenecks application facing and how latest version of Angular can help to improve that.

The post Angular 1 vs Angular 2 vs Angular 4 – Essential differences that enhance your Application Performance! appeared first on Techuz Blog.

He explained that Angular 1 to Angular 2 was a major shift in architecture and backward compatibility is very limited. Developers either need to rewrite the application in Angular 2 or use ngUpgrade to migrate Angular 1 to Angular 2. But we should not worried about future releases because they like to be more transparent, predictable and incremental. That’s why Angular 4 will be backward compatible with Angular 2.

Most of us thinking why there is no Angular 3 release?

The Core Angular libraries in Github are versioned the same way but distributed as different NPM packages. Due to this confusion, the team decided to go with Angular 4 and skipped Angular 3. However, what we need to understand that these are only versioning and by Angular 5, Angular 6 etc it will be just “Angular”

Why this strategic change?

Of course, they have more partners, books, third party solutions with Angular 2 and they don’t want to deliver a wrong message. This means a lot for developers and businesses as they can fearlessly use Angular 2 for products and solutions and rest assure for future compatibility. I hope this is good for angular community and future.

As Angular consultants, we are happy with this announcement and motivated to moving in alignment with Angular js releases.

If you are new to MVC then please read this article https://www.tutorialspoint.com/struts_2/basic_mvc_architecture.htm

Angularjs also follow MVC pattern. In AngularJs $rootScope works like component used in the controller in MVC and as you know component can be used in any controller. In the same way, $rootScope is available in all angular controllers. You can use $rootScope in any controller by injecting it.

In AngularJs $scope works like individual controller in MVC and it’s available per controller. You can not use $scope value in another controller and for that, you need to use $rootScope.

$rootScope is created with ng-app whereas $scope is created with ng-controller.

In angularJs, there may be multiple $scope exists, but exactly one $rootScope is available. We can say that $rootScope is global whereas $scope is local.

If we want to use the $rootScope , How can we use it?

$rootScope is the first scope created in the application. It is available when angular run () method executed.

Example:

var app = angular.module('myApp',[ ]);
app.run(function($rootScope){
$rootScope.Math = Math;
});

We have assigned the Math object into the $rootScope. These will give access to all the JavaScript Math functions like min () and max () in the whole application.

If we want to use the $scope , How can we use it?

The $scope is created in the application controller.

Example:

var app = angular.module('myApp',[ ]);
app.controller('mainController', [‘$scope’, function($scope){
$scope.Math = Math;
}]);

We have assigned Math object into the $scope. These will give access to all the JavaScript Math functions like min () and max () in the main view which implements “mainController”.
