Angular VS ReactJs in the Front End Development World

When it comes to front-end development Angular and ReactJs are considered to be the top two technologies. But to choose between the two is one of the most confusing decisions as both of them have their advantages. Angular and ReactJs both solve frontend development problems but in their own ways. 

Merely sometimes back it was enough for the business to have a website inorder to reach their broader market. But today statistics have shown a huge increase in the types of business websites that are being consumed by the audiences for better interaction with the brand. 

So, the debate between ReactJs and Angular has been an ongoing one. Since both are coming up with new versions every year and also brining in great features, so the decision to select one has become very difficult. 

A brief on ReactJs and Angular 

About ReactJs

ReactJs is an interactive user interface, meaning it is a necessary element of the frontend development of applications. It is a library that you can use to determine how your application is going to look to your users and how they can operate and interact with it. In other words, as per the Model-View-Controller framework, ReactJS creates the upfront view of the website. 

About Angular

In regard with ReactJs, Angular is a complete framework that is built on TypeScript that has the capability to spin code efficiently. It is a wholesome toolkit that has everything to build an entire application or website. 

ReactJs Vs Angular – Showing the difference between the two 

  1. Underlying Architecture 

ReactJs is a Model-View-Controller (MVC) framework with a rendering UI library, that means it uses written code or JSX to create the interface. Biggest advantage is that it does not force on the architecture of your apps and allows you a great deal of freedom during the development process.

Whereas Angular, is a complete MVC that can develop an entire architecture of a website or an app. The little limitation it carries on with it is that it offers minimal flexibility, meaning unlike ReactJs you cannot add functions on the developed architecture making it limited within the scoop of the tools. 

  1. Components 

These are one of the USPs of Angular and ReactJs. Components are the small chunks of codes that can be added to add a specific functionality. But both of these technologies have a very clear distinction in them such as –

ReactJs has a number of free as well as paid UI components that can easily add functionalities to your app or website. Also, these components can be built using JavaScripts. One of the biggest advantage of building your frontend with ReactJs is that it has community that keeps on adding new chunks of code which can be used by anyone.  

Unlike React, Angular doesn’t only imbibe components even though it follows a component-based approach, Angular is a complete framework that can help you easily develop modern, reactive, and component-driven frontend of an application or a website. Which implies that Angular offers more options than developing components which includes such as validations, routing, state management, form, and lots to develop large applications.

  1. Performance 

This is one of the major aspect, analyzing the impact of technology on the performance. 

Document Object Model is the factor that decides the performance. DOM is a programming interface that makes the browser read the object and nodes in applications’ XML or HTML documents. And both Angular and ReactJs maintain their DOM very differently. 

ReactJs is considered to have an edge over Angular but only in its certain respects. Such as the virtual DOM allows its apps to virtually update the changes without rewriting the entire HTML document. This renders updates much quicker, allowing lightning-fast performance regardless of the size of the application, making it great in terms of scalability. 

Whereas, Angular being the complete framework of frontend development in its regular DOM feature makes the application slow in performance. This is the reason that Angular is ideal for developing single-page applications that only updates a single view at a time. 

This way Angular presents lower performance with large and complex multi-faceted applications. However, Angular has Change Detection technique to optimize performance.

  1. Templates 

In ReactJs, templates are called JavaScript XML or JSX, which combines the JavaScript code and markup in one line of code this helps in developing user interfaces efficiently. It is an extension to JavaScriptthat makes use of HTML-like syntax where you can build components by combining code and markup.

On the other hand, Angular uses advance HTML that has Angular ng-if ng-or directives. This indicates that you have to properly learn to code in advanced HTML to code the frontend correctly.  

  1. Data binding 

ReactJs and Angular both has components to render UI. Things to consider when using ReactJs or Angular is their component’s logic that has all the data related to a component that gets displayed in the User Interface. So, the connection between data and the component’s logic is data-binding. 

React has only one way of data binding which means that the model state is updated and then it renders changes to the user interface. But if you change the UI that doesn’t mean that the model state will also change. For that you will have to figure out so ways such as state management libraries or callbacks. 

Whereas in Angular there is two way of data binding that means if you change the UI then the model state will also change and if you change the model state then the user interface will also change. This gives an added advantage to Angular as compared to ReactJs. 

  1. Dependency Injection

It has been seen that certain dependency injection is almost indispensable in data-binding. This is because some of them helps with decoupling where there is no additional data layering in the application model. 

This is a problem in the ReactJs technology as Dependency injection (DI) goes against current architecture of functional programming and immutability. 

But in Angular dependency injection makes it capable of creating different lifecycles of different stores. This implies that the stores creates space for the components mount that makes them smoothly and limitlessly available to components’ children.  

In ReactJs the language makes use of global app state that maps different components but this way you will be introducing bugs when cleaning component unmount. 

Websites that are Built on Angular and ReactJs 

Forbes which is one of the world’s most visited websites is built on Angular. The website has the capacity to respond to more than 74 million queries on a monthly basis in the United States alone. Angular has given the website the authority to work on reusable codebase, provides uninterrupted user experience, and also the support and maintenance are easy. 

Example of ReactJs is supreme Facebook, the website is built on React Library and its products. Facebook developers use React to create responsive UI. React and also maintain high website performance. Lately, Facebook has supported 2.45 billion monthly active users and this number is continuously growing. 

To Conclude 

So, before you kickstart your frontend development it is important that you keep these aspects in your mind. With these it is also necessary for you to know that the learning curve of these two technologies are very different. As ReactJs is JavaScript programming language, it is way easier to work on this language because of its simple design, detailed documentation, libraries, and JSX. In contrast with ReactJs, Angular is complex and developer needs to learn the syntax. But once there is a hand on syntax the technology gives multiple options to solve a single problem.

Real World Implication of Microservices in the Fintech Industry

The transformation of the monolithic architecture to microservices architecture is one of the most heroic steps that you might take to upswing your business. So, if you are really looking forward to scale your infrastructure and also speed up while deflecting high supervision costs then microservices is the right solution. 

Especially, in a FinTech ecosystem that is running to establish itself in the digital centric world. And this being the reason that they are experimenting their digital approaches with highly scalable, flexible, and efficient architectures for their infrastructures. To get an outcome of performing well in the competition; and also satisfying and solving their customers’ issues.  

The outmost benefit of Microservices Architecture is its capability to provide flexibility, structural scalability, and reduced costs. The Monolithic structure has often failed when you want to scale your architecture. And since, financial services can never remain constant there is always scope to extend its capabilities as the world is changing. 

The long before financial institutions have legacy systems that carry the baggage of centralized database that are tightly coupled sub system. Microservices give them an approach to separate database from every services. Whenever a new service or a feature is deployed in an infrastructure or product then it has its own separate database and this way entire system doesn’t get affected. The architecture offers solution to fetch the only required data belonging to a specific service. The service reflects through an endpoint or a middleware platform, implying that a large scale service can be implemented with No SQL database for heavy scenarios. 

Example of a real life Bank with Monolithic architecture:

Danske Bank worked on the monolithic architecture that mostly relied on the sharing of the resources and therefore the processes couldn’t function independently. The major issue with the monolithic architecture was its scalability and maintainability. Their system wasn’t componentized and shared software libraries. Also monolithic architecture has stack dependencies that stops the embedment of the latest technologies. Additionally, with this architecture banking application had the fear of sending over unencrypted data of the users. 

Monolithic application involves huge and complex code, making the response time of a web application high, and also, unacceptable.

And as the web service coincides with the monolith ecosystem, they have a greater downtime and are unavailable each time there is an integration or upgradation of new feature in the application. Which states that the B2B dependency on the application can further complicate decision-making.   

Example of a real life Fintech organization having Microservice architecture:

Monzo Bank, a London Based bank uses microservices architecture to build a mobile first U.K digital bank. It has established a cloud native mobile-first digital bank while also complying with regulations. It has the technology foundation that can provide what all the traditional banks cannot  with an additional cloud enabled advantage. 

Monzo uses AWS hosting for its core banking needs to enable scalability and flexibility with its cloud computing strength, also eliminating the doubts in terms of capacity, infrastructure, and provisioning management. 

Monzo has established its core banking systems from scratch with the help of microservices architecture, with multiple virtualized servers having container tools such as Docker and Kubernetes. It architecture makes a hub of small elements that can scale as an entity, communicate synchronously or asynchronously, and have APIs. Their banking application also has a platform-agnostic for easy interoperability. 

Outcome of adopting such a system

  1. Monzo runs on an active data centre that avoid any failures or downtime attached to their banking application
  2. Its AWS hosting offers sophisticated security, auditability, and encryption levels to remain compliant with the banking regulations. 
  3. Their customer experience is powered by technology making them, by far the most significant is customer centricity; elevating and enhancing their infrastructure according to the competitive landscape for FinTech organizations today.
  4. Their core banking system has a technology architecture that is open, agnostic, scalable, secure, and 3rd Platform–enabled.
  5. As a startup it always had the advantage to develop its infrastructure from scratch and be totally cloud driven.  From the very start they understood that simple computation won’t take them out of the firewall but rather give them a data driven and secure architecture that can totally redesign their system’s infrastructure.

The biggest benefit Monzo has gained from microservices is organisational flexibility, Suhail Patel, Monzo’s backend engineer explained this by quoting – 

“We build services which are granular enough to be easily understood. Ownership of services is well-defined but can be fluid based on the goals of the company. Monzo has grown significantly over the past 24 months; the structure of existing teams and emergence of new teams has changed significantly as a result.”

Benefits of inducing Microservices in financial institutions 

There are considerable advantages that microservices can provide with a robust IT strategy that is sufficient for smooth transition. 

  • Transmission and redeployment of new application features without fear of failing the entire application.
  • Increased agility and decoupled release cycles implying app updates can be developed and deployed within hours.
  • With microservices architecture the infrastructure can be easily replicated and can be more effectively help in scaling growth in terms of users and transaction volumes. 
  • As database is much less interdependent, microservices can level down failure footprint. 
  • Microservices architecture makes banking application easier to refactor or replace going forwards.
  • As microservices can be easily replicated it can help increase structural scalability. 
  • Microservices architecture helps provide improved security levels in the application this way the threats do not breach the entire app and the other elements can left protected. 

Microservices Architecture – Ideal platform for Platform Banking 

Microservice architecture provides accelerated integration with the third parties and efficiency in the process, which proves to be a major competitive factor in the platform banking ecosystem. The traditional banking system that goes with the monolithic approach has multiple points of integrations and batch processing which is highly inefficient and slows the entire process. And the microservices architecture can bring in a phased approach that minimises risk with a deliberate process in the near-term and long-term objectives. Each element can be developed, updated, and managed independently, making microservices based applications easier to work on and maintain. 

To Conclude

Banks and Financial Institutes must adopt microservices architecture in order to create and enter new markets, and also establish themselves rightly to gain all the profits that a new market can offer. With the platform banking the FinTech industry will not only introduce new sources of revenue, but also present enhanced customer experience along with the improved operational efficiency reciprocating a lot of margin. 

Also, in the long-term, banks and financial institutes must move to a more sophisticated microservices based core platform in coordination with service mesh. Banks are currently trying to develop a marketplace that should have a microservices platform providing and scaling banking services as individual stacks categorized by product domains.

Consider this example, an organization owner can develop a marketplace that can combine industry leading onboarding services from a fintech with its inhouse underwriting capabilities and book the receivables to a third party bank. And also a customer availing a loan from their platform would be able to protect from the various levels in the back end. Such a composition can be executed effectively only with a microservices-based architecture. 

So, the goal of microservices architecture is to help financial institutes and banks align together services from different platforms into unity to offer a unique service to customers.

Why, When & How should You Migrate a Native App to a Cross-Platform App?

One of the leading markets right now is mobile app development. According to a Business of Apps, it is estimated that the global number of smartphone users will increase to 3.5 billion by 2020. There are more than 4 million apps on both the Apple store and Android Playstore, which targets an audience of more than 2 billion. However, App development is not what it used to be. It has become more challenging to develop a functioning application these days.

The options that are available for app developers are myriad these days. App developers face the dilemma as to which is the platform they shall use for app development. Either they can choose to make a native app or a cross-platform app. This blog will explore more about how and when an app developer can transform a native app into a cross platform app. What is the benefit of such transformation? Before answering these crucial questions, let us have a quick look at what are these types of applications and what are the differences that exist between them.

Native App

A native application is specifically designed to run on a single platform. It will not run on other platforms. For instance , if an application is developed to run on an android, it would run on other platforms like Windows or IoS. You can use app development tools like Java or Kotlin to develop apps exclusively for android and applications like Swift and Objective C for IoS apps. 

While developing a native application certainly has its pros, it is not without its shortcomings. Let us dig a little deeper into these-

  • Pros 
    • Wider Functionality

Developing a native app offers seamless options to app developers to access all API and tools provided by the platform.

  • Better Support

You will get support from the app store if you have a native app. Additionally, it has more possibility for being rated as a top application in the app store as it also offers faster and much more efficient performance.

  • Better Performance

 A native app may offer better performance as there is a direct interaction between the code and underlying resources. It also offers device-specific features and a consistent UI.

  • Cons
    • Costly

Developing a native application can prove too much costlier than a cross platform application. You will have to constitute two different teams who will work on app development on two different platforms.

  • Less value for time

Time devoted to development of native apps can prove to be of lesser value, as it will only run on a single platform. ‘

  • Less Opportunity for growth

A native application can prove to give lesser returns for your time and money as it is bound to run on a single platform. It has much lesser Opportunity for growth as it will be available only on a single platform.

  • Lower Reach

Native apps can only reach out to a lesser number of people, as their usage is limited to only one single platform.

Cross-Platform Application

These applications are designed to run on multiple platforms like IOS and android. Various tools like ReactNative, Xamarin, and Flutter are used to achieve this. While the Cross-Platform application certainly has its shortcomings, like it compromises performance, its benefits outweigh them. It saves a lot of your precious time while offering a better return for your investment. So, if you have developed a native application, you would want to transform it to a cross-platform. 

Why should you migrate your native app to the Cross-platform?

  • Reusable Code: A cross-platform apps code is used to develop a single application on multiple platforms. This helps to save up time and effort for the development team 
  • Broader Reach: Your cross-platform application will reach out to a larger audience, which will in turn, prove to be a better return for your investment. 
  • Customization: A cross-platform application is customizable according to each platform. You do not need to devote extra time to customize the application separately for each application.  
  • Easier Maintenance: It is easier to maintain a cross-platform application as errors are rectifiable through a single code rather than working on the application on different platforms. 
  • Cloud Integration – Cross Platform apps come equipped with plugins and extensions, facilitating their integration with the cloud system.

When should you migrate your native app to a cross-platform app?

Well, it depends upon a lot of factors. As mentioned above, there are various shortcomings for a native application. There are various advantages associated with a cross-platform application. However, making the final decision lies squarely upon your shoulders; there are various factors that you must consider before making the final decision. Let us have a look at a few of them –

  • Nature of the Application: If you want to develop an application that involves complex tools and functions, you should probably stick to a native application. Some of these complexities in a native mobile application includes certain advanced features like real-time sync, media processing and custom animation. However, if your app uses basic features, then you could look for a cross-platform application.
  • Cost: As mentioned above, developing a native application could prove to be a costly affair, As you will have to develop two different teams working on app development for different platforms making a cross-platform is undoubtedly cost-effective.
  • UI/UX – If you are making an application that wishes to deliver breathtaking visuals and a much more enhanced application, you should opt for a native application as it would allow you to exploit UI/UX to deliver optimum experience fully.

How should you migrate your native app to a cross-platform app?

  • STEP 1

Selecting tool: The first step towards migrating your app to a cross-platform requires selecting an app development tool. There are various tools which you can use for this. A few of these are React Native, Flutter and Ionic. React Native is an open source programming language which supports both iOS and Android with a seamless UI/UX interface whereas Ionic is an open-source SDK for cross-platform mobile app development. Flutter on the other hand is the latest technology by Google which enables app developers to use a single codebase. 

  • STEP 2

UI/UX Design – App developers must abide by UI guidelines while simultaneously addressing the design needs for different platforms. Before, the proceeding must ensure that the app developer knows these design needs for different platforms.

  • STEP 3

Selecting App Modules – Another crucial aspect of cross-platform application development is selecting an app module for cross-platform app development. It significantly reduces the time for app development and helps give adequate exposure to native SDKs.

  • STEP 4

Choosing a dedicated library for both Android and iOS – When you are migrating your native mobile app to a cross-platform mobile application, you should have a dedicated library which is compatible in both Android and iOS. There are also several issues related to deployment and packing too. To avoid these, you should incrementally test your mobile application in both Android and iOS so that there no bugs are present during deployment. 

  • STEP 5

Accommodating features for different platforms – So, when you develop a cross-platform application the difference between different platforms is not limited to the programming language or operating system. There are numerous features in different platforms that might differ significantly from each other, like camera, geolocation, gyroscope, compass, Twitter, etc. Besides these, certain attributes could be specific to a device like a screen layout, keyboard layout, push notifications, touch, and gestures, etc.

  • STEP 6

App testing and App Store Approval –The last part of migrating your application to a cross-platform is perhaps the most critical one. It would help if you aimed for a rigorous process review for your application, as there is some margin for error after your app development. Make sure you thoroughly test your app before the final launch date.

In a nutshell, you should keep the factors in mind while you are migrating a native application to a cross-platform application. Do you have any more questions? Leave them in the comments below. We will get back to you with the answers soon.
