In this blog, you will get a glimpse of the top Java frameworks used by Java developers along with their pros and cons. But, before we dive deeper into it, let’s quickly run through what Java frameworks are and why they are used?

What are Java frameworks and why they are used?

A Java framework is a body of pre-written code to enable easier, faster, and efficient development as well as the deployment of the web apps. It is a kind of template which the developers can use for Java web app development by adding their own code and re-using the components in it.
A Java framework alleviates the need to write the code from scratch. It gives a structure to the web apps by automating a lot of things for consistent and accurate results. These may even include predefined functions and classes for interacting with software systems or managing the hardware devices, depending upon the type of framework. One can use the framework by calling the inheritance, functions, providing callbacks, listeners, etc.

Promising Java Frameworks to Know in 2020!

There are multiple frameworks available in the market for Java web app development and they all serve different purposes and good for specific requirements. Here are the most commonly used Java frameworks that you must know.

Noteworthy Pros and Cons of the React Native Framework!

Noteworthy Pros and Cons of the React Native Framework!
React Native App Development
Why does every next-gen organization want to leverage mobility solutions today? That’s because the mobile apps have become the fast-track solution to influence the audiences. So, every company wants a dedicated mobile app.
But the real confusion arises when it comes to the choice of the right framework for mobile app development. As there are a vast number of competent frameworks available in the market, selecting the right framework becomes challenging.
What if there exists a promising framework that helps to design top-quality apps with fewer resources?
The Name of such a framework is React Native and is developed by Facebook and Instagram. React Native mobile app development is preferred by several big players in the market like Facebook, UberEats, Delivery.com, Skype, Bloomberg, Instagram, Vogue, Tesla, etc. to name a few. Javascript and JSX are used to create IOS and Android native apps. With the help of native layout components, React Native is able to create convincing UIs that are pretty much similar to native apps.
Reusability of components, sharable code repository and, “Learn once, write anything” objective, have already made React Native a winning choice for cross-platform app development. So, if you are going to build your next app with this framework or going to hire a React Native development company for your project, this blog will help you to make an informed decision. Here’s a list of some noteworthy pros and cons of the React Native framework.
React native framework

Pros of using React Native for your Mobile App

Time and Cost-effective Solution

React Native app development allows the re-usability of the code i.e. the same code is being used for both Android and iOS platforms. As Javascript is used for development, it gives an opportunity for the developers to use the same codebase not only for mobile platforms but also for React web applications. This makes the job smoother, faster and easier for developers. Targeting multiple OS with one code reduces the coding time by 30-35% approximately. A single team can code for multiple platforms. As a result, team-size is reduced and the project becomes manageable.
React Native has ‘ready-to-apply’ components. So, instead of writing the code from scratch, the React Native app developers can use these components and save their efforts. All these factors boost the cost-effectiveness. The app can be launched in the market at the earliest, improving the time-to-market.

Modular architecture

This framework has a modular architecture. It allows the developers to segregate the functions of the code into the blocks called modules. These modules are interchangeable and free and they can be re-used for web and mobile APIs. Due to this, React Native mobile app development becomes flexible, and updating the apps becomes extremely easy.

Native App-like Performance

This framework uses native modules and native controls, which enhances the performance of the apps. The apps built using React Native render their user interface using the native APIs. Consequently, the performance of these apps is quite native-like.

Growing Community- Support

React Native is an open-source framework and anyone can contribute to its growth. This community of talented and experienced React Native app developers helps anyone and everyone who needs a piece of advice on an issue. It has active support from GitHub and Facebook. Facebook itself uses this framework and their team constantly works to introduce new features, functionalities, libraries as well. Also, companies like Microsoft, Callstack, Infinite Red, Software Mansion, etc. have made their contribution to React Native.

Good Reliability and Stability

Despite being a new framework comparatively, it is much stable and reliable. It has simplified data binding due to which child elements do not affect the parent data. So, if a developer changes any object, s/he would need to modify its state and then accordingly apply the updates, letting only allowed components to be upgraded.

‘Hot-reload’ feature

This is another precious feature of React Native. If a developer makes changes in the code or tweaks the UI, it immediately reflects in the apps, like a live preview even if the apps are running. The developer does not need to rebuild the app for every small change made in the code. It enables the implementation of feedbacks faster and reduces the wait time.

Third-party plugin support

Third-party plugins are usually not considered to be secure and so, the developers face challenges while using them. React Native, on the other hand, has many third-party libraries that are quite flexible and can be used swiftly. Also, there are pragmatic interfaces in React Native having customization options.

Simplified User Interface

React Native looks more like a JavaScript library and not a framework, where the user interfaces are simplified and platform-specific. So, the apps designed in React Native are more responsive and have a smoother feel.

Declarative coding style

The declarative coding style in React Native simplifies the coding process and coding paradigms which makes the development understandable. The code can be easily read and understand, simply by looking at it.

Cons of using React Native for App Development

Small Collection of Components

React Native is still in its infancy. Though it has ‘ready-made’ components to use, the collection is small. Some of the components may even not meet the expected standards, as they aren’t developed by official developers. This limits the developers to create simple basic apps. For developing an app with custom native-like features, one might have to maintain 3 codebases like react native, iOS, and Android.

Memory Management

React Native is based on JavaScript and not suited for the apps that are computation intensive. In terms of memory usage and management, float computations are handled inefficiently and the speed and performance are significantly degraded.

Need for Native Developers

To solve some of the issues in React Native, native modules are required. However, implementing them requires expertise in Java/ Swift/Objective-C and detailed knowledge of a specific platform. So, we can’t deny that occasionally, some help from native developers may be needed. This could be problematic especially to small enterprises or start-ups.

Lacks the Security Robustness

Being an open-source framework the security robustness of React Native may get affected. While creating data-sensitive apps like banking or financial apps, experts advise that this framework should not be used as it is based on JavaScript which is known for its instability.

Isn’t Ideal for All Business Requirements

React Native is known for saving time and money, however, it may not suit every business requirement. At times, when complex features are required to be used in the apps, React Native may not be the apt choice.

Key Takeaways:

React Native has been one of the most sought after frameworks for mobile app development. Though it has its downfalls like every other framework, its advantages surpass the downfalls. Also, the huge React community growing at a fast pace is highly likely to develop more efficient and advanced components and functionalities, making it ‘THE BEST’ framework in the future.

healthcare software solutions
“Life is Unpredictable and You Never Know what is Coming Next!”
The COVID-19 pandemic hit the world a few months back and everything changed suddenly. Thousands of people have lost their lives, businesses have come to a standstill and economies are disrupting like never before!
In this panicking situation, everyone is finding out ways to contribute their bit against this COVID-19 war. There are array of technological innovations being carried out to prevent the spreading of coronavirus. As a global provider of new-age healthcare software solutions, Biz4Solutions is developing several mobile apps to support hospitals and clinics in their response to the COVID-19 pandemic. Our team is developing social awareness apps, informative apps, counselling apps and similar other medical apps. We are constantly finding new ways to deal with this crisis using advanced technology.

How our healthcare mobile apps can benefit during the COVID-19 chaos?

Healthcare mobile app

Counselling Apps

Several countries are under lockdown and many people are home-quarantined due to the coronavirus outbreak. Social distancing can cause anxiety and take a toll on mental health. For managing stress and fear in these times, the significance of counselling can’t be underestimated. Counselling apps are already helping a number of people across the globe. People can use these apps to hire counsellors on-demand.
Biz4Solutions has built an On-Demand healthcare apps using which, people can book online sessions or appointments with healthcare providers. For instance, the Phlex65 app developed by us is a practical solution for older people to hire licensed care providers from nearby areas. These care providers help old people in activities like taking medicines, healthy cooking, bathing, etc. This app also empowers care providers. We can also develop a similar counselling app.

Social Awareness Apps

Due to lockdowns being imposed all over the world because of Covid19 pandemic, people are forced to stay home. In such situations, people have started spending most of their time on their smartphones and using social media apps on a large scale to find all sorts of information about the pandemic. Social media awareness apps can educate the people and the affected patients in these times. If someone needs to know what precautions are to be taken during this lockdown period, social awareness apps can be helpful. If someone needs groceries or masks or general medicines, social awareness apps can be used for getting contact details of nearby shops, medical stores, etc.
Biz4Solutions has developed an application named Link, which is a social networking and awareness app. People with similar health interests can connect online, chat with each other and create groups. They can share information like best doctors nearby, cheapest medications, health management tips, etc. on this social platform. They can share images, audios or videos as well. This app uses geo-location tracking and ‘push notifications’ features too.

Patient-Doctor Communication Apps

In the lockdown conditions, a patient-doctor communication app is like a blessing. If an old person with chronic ailments or a pregnant lady needs any guidance, they can immediately contact a doctor online using these apps. Likewise, if someone shows symptoms similar to COVID-19 and wants online help from the doctors, s/he can contact the doctors using these apps. These apps provide real-time access to doctors. We have developed similar apps where the patient can book the appointment for video conferencing with the healthcare providers, make the payments and then go ahead with the video calling session. During video conferencing session, patient can speak directly to the physician and explain his symptoms. Physician can then diagnose the condition and prescribe for the medicines.

Informative Apps

In these critical times, several messages about fake coronavirus cures and other misinformation are circulating on social media and other communication platforms. There is a need for genuine apps that provide information only from trusted and authorized sources like the World Health Organization (WHO) or Centers for Disease Control and Prevention (CDC). Such apps will help to curb the confusion amongst masses in these panicking times.
Biz4Solutions has developed highly secure and HIPAA compliant apps for renowned hospitals and other healthcare organizations across the globe. We ensure that all the data is safe and its privacy is maintained. We always rely on trusted and authentic sources for the information we need.

Medical Emergency Response Apps

Biz4Solutions has developed an outstanding app that instantly connects the patients to their physicians or medical professionals in case of an emergency. During life-threatening situations, the patients can use this app and get the required assistance immediately to save their life. Such apps help to send helpful messages and reliable emergency alerts to the ones trapped in critical situations.

Total Management Apps for Physicians

Many medium and large-sized hospitals are going through a tough time now. Patients are visiting hospitals in large numbers and management of hospitals is becoming a challenge. But thanks to the Total Management App and the Practice Management System (PMS) developed at Biz4Solutions!
These apps and systems help hospitals in many ways. They are useful in integrating the medical data of the patients and record it in the centralized systems. This data, which is saved in the digital format, can be accessed by the doctors immediately to provide better treatment of patients. The doctors working in different branches of hospitals too can access it. This data helps in improved-decision making.
It is also used for making the appointment-scheduling process self-automated. The patients can book appointments as per their availability in the slots when doctors are available. A PMS is a comprehensive solution to many tasks in a hospital

Why HIPAA Compliance plays a major role in protecting data privacy in Healthcare Apps

Why HIPAA Compliance plays a major role in protecting data privacy in Healthcare Apps
Healthcare mobile app
The healthcare sector has progressed enormously in this era of digitalization. Global spending on healthcare services is on the rise and this industry has a bright future for sure. Healthcare providers are investing in advanced technologies to ensure high-quality services to their patients. Users of mobile app are able to actively keep track of basic health stats such as consulting a physician over the app, measuring their heart rate, checking their glucose level, BMI level, booking appointments, accessibility of Electronic Health Records (EHR) both to patients and Physicians, etc.
But what comes in the picture here is the security of data. It is one of the biggest concerns of the healthcare industry. Data breaches, cyber-attacks, hacking, etc. are common today. They can put the sensitive health data of patients at risk, causing massive losses to healthcare organizations. This data can be at high risk especially while using a healthcare mobile app . So, healthcare organizations need to be more vigilant of their IT and cyber-security practices. In order to avoid theft, fraud, misuse, identity of the patient data, all healthcare apps in US have to be HIPAA compliant and strictly abide by the HIPAA rules and regulations.

What is HIPAA?

HIPAA stands for Health Insurance Portability and Accountability Act. The Act includes a set of minimum security and privacy standards for protection, confidentiality and availability of sensitive patient information and their medical records. It is issued by the federal regulators. Initially, the purpose of enacting this act was to improve the effectiveness and efficiency of U.S. healthcare organizations. Over time, many rules were added to the Act and the purpose was to protect the individually identifiable health information i.e. Protected Health Information (PHI). These rules influence the working and security of healthcare mobile apps.
The entities covered under HIPAA are healthcare clearinghouses, health plans, and healthcare providers that make use of electronic media for transmitting data like health claims, referral authorizations, coordination of benefits, etc. These entities may comprise of individual practitioners, small or large organizations, institutions, research centres and government agencies as well.

Why HIPAA Compliance plays a major role in protecting data privacy in Healthcare Apps?

It is federally mandated for the healthcare organizations and other healthcare IT service providers (like healthcare mobile app development services, web portal development services, etc.), to adhere to HIPAA for data privacy. So let us understand how HIPAA compliance plays a major role in protecting data privacy in Healthcare Apps:
HIPAA Compliance mobile apps

Data Privacy

The importance of data capturing has increased over the years for improving the overall healthcare operations, with the use of advanced technologies like the Internet of Things, Robotic Process Automation, etc. Personal information of hundreds of patients, their contact details and their medical reports are recorded and saved digitally by many hospital bodies. So, data privacy is important to ensure that only relevant information is shared with the right people and at the right time. This also helps to build trust among the patients.
HIPAA compliant apps abide by strict rules to ensure data privacy. They have to display a link in the privacy policy of the mobile app, while the app is downloaded by the users. The apps take consent from the patients or users before using their information. Also, the users are informed about how their data will be used. These apps are hosted on HIPAA compliant servers for ensuring that all the HIPAA standards are met correctly.

Security of the medical data

Data breaches can be devastating for patients, hospitals and similar healthcare systems. There could be insurance frauds, extortion or identity thefts and once this data is hacked or lost, it can be disastrous for both patient and healthcare providers. Hence it is of utmost importance to secure the data of patients, hospital staff or other back-office data.
A HIPAA compliant mobile app ensures that healthcare data remains safe and secure. The users of these apps can access the data only through a secure login and 2 factor authentications are applied as well for more security. All the data presented in the app can be only accessed using a secure PHI key. Also, in case the mobile device is stolen or lost, the personal user information cannot be accessed easily due to the advanced security and encryption. Data being stored on database servers are also encrypted so that the medical data cannot be easily accessible.

Secure data transmission

In many large Healthcare Facilities having multiple branches, the medical data needs to be shared with many Physicians or concerned authorities. If such a hospital uses a mobile app for data transmission, it must be in accordance with HIPAA rules and regulations. To ensure that the user data in the app isn’t accessed inappropriately or modified abruptly, the data should be audited from time to time. In case the patients are monitored remotely through wearable technology, IoT or AI, only the necessary data will be transferred to ensure the security of data. There are integrity control mechanisms in place in the communication networks of the apps.
A HIPAA compliant mobile app ensures that the amount of sensitive data that is stored on them has access limitations when the device is carried outside the premises of the hospital. Also, when these apps are deleted by the users, any related health data is deleted completely from the device. It is noteworthy that HIPAA laws apply only to the apps using PHI i.e. protected health information. So, the data transferred from an app that does not deal with personally identifiable information, is not needed to be protected under HIPAA.

Notification of medical records breaches

There is a possibility of sensitive healthcare data getting fraudulently accessed by hackers. If the Healthcare Mobile app is HIPAA compliant, then it needs to notify affected individuals about the breach of data without unreasonable delay and should not be sent later than 60 days. So it is mandatory for an app that adheres to HIPAA to abide by data breach notification laws. Under these laws, the eligible data breaches are obliged to alert the users or relevant parties.
Some of the data breaches may not cause serious harm to hospitals or medical organizations. In case any disclosure of information, unauthorized access to it or loss of personal information is bound to cause serious damage, such breaches are called eligible data breaches. They can result in financial harm or even harm the reputation of the healthcare organizations. So, the mobile app they use should be HIPAA compliant and send timely notifications to users.

Key Takeaways:

Data is the biggest asset in any industry today and healthcare organizations are no exception to it. Today, most hospitals use diverse technologies and mobile apps for providing better services to their patients. However, the medical data can be vulnerable to threats. So, it is necessary for the healthcare apps and systems to follow HIPAA guidelines. Under HIPAA compliance, the covered entities need to put physical, technical and administrative safeguards for PHI in place and thus ensure privacy, confidentiality, integrity and security of the data.

Ruby on Rails and its Role in Web Development for Diverse Businesses!

Ruby on Rails and its Role in Web Development for Diverse Businesses!
Ruby on Rails (RoR) development
What factors do you consider while choosing a programming language for your web app development? Scalability? Level of support? Ease of development? Cost? Availability of libraries? Or all of these? Well, amongst hundreds of programming languages available today, Ruby on Rails (RoR) is one such language offering all these benefits. RoR is quite popular and highly preferred by a lot of companies, right from start-ups to giants as a primary framework for web development. It is ideal for e-commerce sites, healthcare, retail, social media platforms and content management systems as well.
So, let’s review the top reasons of why Ruby on Rails (RoR) Development is widely chosen for developing web apps.

Why choose Ruby on Rails for Web Development?

RoR is an open-source server-side framework used for cross-platform web development. It ensures fast and easy development of apps. It is written in Ruby, a dynamic and object-oriented programming language. It is distributed under the MIT license.
Ruby on Rails (RoR) web app development

Own Plug and Play Apps

In RoR, the programmers can develop building blocks for plug-and-play functionality. This allows taking elements from the current apps built using RoR and use them in future projects. So, the developers don’t need to develop the same elements from scratch. One can develop multi-purpose, expandable apps in RoR.
Also, it is not easy to write a user-friendly and structured code. However, RoR has plenty of ready-to-use tools, plugins, modules and easily configurable components to help the developers write less code with more clarity and high quality.
In some programming languages, analyzing the starting and endpoint of the code is quite difficult. For fixing any issues, one has to start from scratch which can be time-consuming as well as costly. However, this is not the case in RoR. It is quite simple to understand and moving the code conventions from one developer to the other is quite easy.
Also, when an application is developed, there could be the need to enhance the app later. In RoR, there is an advantage of clean codes which proves to be a savior in this case.

Model-View-Controller (MVC) Architecture

RoR is based on the MVC (Model View Controller) architecture which supports parallel development i.e. many developers can simultaneously work on the app, that too on different pieces of functionalities. RoR has a simple and readable syntax allowing the RoR Developers to execute more in less coding. It lets the developers implement the tests and evaluate the code, without any third-party testing tools. It has many inbuilt solutions to support a variety of problems and also the support of the Ruby community.

Conventions over Configurations Model

RoR uses the “Convention over Configuration” model which is the key principle and a golden path for the RoR Developers. In this model, the environment (libraries, systems, language, etc.) assumes many logical situations instead of programmer-defined configurations. The developers don’t need to create their own rule every time. As a result, the decisions that the developers have to make while coding are reduced without losing flexibility. They don’t need to spend more time on configuring the files. It saves the programming efforts, speeds up the development process and improves productivity.

Rich Support of Libraries and Components

Ruby on Rails (RoR) Development is blessed with rich libraries, called gems. These libraries can be used to implement features like payment integration, authentication, etc. Also, there are generators in RoR, which enable the automation of basic CRUD functions. Modules are other powerful tools for Ruby developers, which help in the organization of Ruby classes, constants, methods, etc. and unify them into categories. The support of such features and libraries enables faster web app development. Also, there is a massive community of RoR to help the developers in any challenges they may face.

High Scalability

Scalability is what every business looks for while selecting a programming language for web app development. RoR has high scalability which makes it quite popular. It supports caching out of the box activity and allows viewing of fragment caching within the app’s code. It uses Redis for storing cache. A remote multi-server automation tool can also be implemented to automate the pushing of new app variants to the deployment location. Rails allows you to use Chef, the cloud infrastructure framework written in Ruby. The function of Chef is managing the infrastructure dependencies, creating the folder structures, bootstrapping the complete system and updating the system configurations with lesser commands. Also, the high scalability of the RoR improves the background activities and ensures a smooth user experience. This can be done using Sidekiq or Resque.

Easy Maintenance and Huge Support

RoR is quite easy to maintain and provides a vulnerable service due to the advantages of both- Ruby and Rails. It is known for its stability and predictability. Adding new functionalities and making changes in the existing code can be done with ease. Especially in the case of bigger projects, upgrading the apps is possible without much complexity. In case there is a need to substitute the development team, it isn’t a big issue for RoR applications.
RoR has ample support for a large community named RubyGems. They help in solving any issues and hosting solutions.

Key Takeaways:

Some of the most reputed giants like Airbnb, Bloomberg, GitHub, Fiverr, Shopify, Basecamp, etc. have used Ruby on Rails Development Services for their projects. It is a fit for every industry- small or large. Overall, RoR is excellent considering the factors like performance, coding, quality, community support, scalability, modifications, etc.
RoR is easy to learn, read and comprehend. It is written in simple English and uses the domain-specific language of its own. It is a well-established language having similarities in integration with languages like Python, Perl, etc. It is based on Agile software development principles which improves productivity and management of the project. Due to all such benefits, its demand has increased among the developers and business owners who want to develop mobile apps.

Why Start-ups Prefer Swift Over Objective-C

Why Start-ups Prefer Swift Over Objective-C
iOS App Development
If you are willing to develop a futuristic iOS app for your target audience, then Swift should be your preferred choice. It is cost-effective, has advanced features, has more powerful tools, requires less coding efforts as the language is intuitive and thus easier to learn. This modern programming language is going to survive for long due to the plethora of benefits that it offers, as compared to its old competitor, Objective-C.
Earlier, Objective-C was principally used for building iOS applications. However, it became out-dated slowly due to the lack of many valuable features that other new-age programming languages had. Apple Corp had worked on Objective-C improvements for almost 6 years and understood that a better language could be introduced for writing mobile applications. Due to such loopholes of Objective-C, Apple introduced an advanced language in 2014- Swift which had pioneering features to accelerate the iOS app development.
Swift is general-purpose, multi-paradigm, and compiled language. It is a fast, safe and interactive language specially developed for iOS, macOS, Linux, tvOS and watchOS. It soon superseded Objective-C and became the favorite of developers across the world. Several giants like LinkedIn, IBM, Facebook, Mozilla, Uber, etc. were already using Swift but now, even start-ups have started focussing on it.
In this blog, we will look at the key reasons why start-ups choose Swift instead of Objective-C.

Top Reasons why Start-ups Prefer Swift over Objective-C

Swift app development services
Swift is quite successful today not only because it is feature-rich and well-structured, but also due to a huge support of millions of people, globally. Its independently managed conferences enhance the Swift community. Also, there are two main differences between Swift and Objective-C:
  • Swift isn’t a superset of C, so, it can freely make use of syntax constructs. This enables implementation of custom operators.
  • Swift is not dynamically typed but it is statically typed, due to which it can take benefit of a number of recent advancements in the type systems.
Let us know in detail about what more is there for start-ups to prefer Swift over Objective-C.

Open-Source and Fast-Growing Language

Swift is the fastest-growing open-source language and has great potential. It can be immediately accessible to anyone and the start-ups can take advantage of this. Also, Swift can be applied across several platforms and backend infrastructure as well since it is open-source. It is also available on Linux and efforts are being made to bring it to Windows. Swift receives feedback from the iOS app development community to make improvements to get more structured. Comparatively, Objective-C isn’t an open-source language and also becoming out-dated gradually.

Less Coding Efforts and Less Prone to Errors

Swift is a functional programming language and allows passing functions as variables. It also allows manipulating of data and text strings. This lets the Swift app developers develop generic code which reduces the coding efforts to a great extent. So, writing, reading and modifying the code is easier in Swift which ensures better readability. Also, this language has smaller code lengths due to the use of a feature called- Type interface. This feature helps to avoid incorrect coding and provides less error-prone code.
When a null optional variable is used in Swift, a run-time crash is triggered instantaneously. Due to its consistent behavior, this crash forces the bug-fixing process and so, the bugs get fixed instantly. As a result, even the development time reduces.
However, in Objective-C, complete code needs to be written every time there is a change in code. So, it needs extensive coding and has greater execution time.

Shorter Time-to-Market

Shorter time-to-market is a critical factor for start-ups. What they want is good-quality products in less time. Swift has package managers which allow the developers to focus on the logic, push their packages for collaboration with others, and use different packages for quickly assembling the applications while significantly reducing the time-to-market.
There are many other speed-based advantages that Swift offers over Objective-C apps while developing iOS apps due to which start-ups prefer Swift.

Highly Safe and Secure

Safety and security is a very important factor while developing mobile apps. Swift has an all-inclusive Security Framework having several APIs that handle authorization services, certificates, keys, trust policies, etc. Some APIs are also used to apply cryptography encryption on the messages. Also, as discussed earlier, the use of a nil optional variable makes the bug-fixing process easier and immediate.
Syntax in Swift forces the coders to write a clean and consistent code. It not only saves time but also supports the safety of the apps, though it may feel strict sometimes. The way Swift handles the bugs ensures safer applications as compared to Objective-C.

Needs less Maintenance

Swift is a preferred choice of start-ups for one more significant reason. This programming language doesn’t have any legacy code and so, needs lesser maintenance as compared to Objective-C. Objective-C depends on C for its evolution, however, Swift is not. In C, iOS app developers need to maintain and manage two separate code files- (.h) header file and (.m) implementation file, for better efficiency and building time of the app. The same legacy is carried forward by Objective-C, which can be cumbersome to manage at times. In the case of Swift, only one single file- (.swift) needs to be maintained, making the overall maintenance quite easier.

Has a Bright Future

Swift is a well-designed and well-organized programming language. It provides an enhanced development process along with some excellent features while making the job of the developers easier.
Though Swift has emerged just a couple of years ago, yet it has made a tremendous evolution. Undoubtedly, Objective-C won’t vanish from the market but it has definitely started losing its place since Swift came in the picture. Also, it is evident from the conferences held by Apple and its software releases that Apple is going to develop Swift with some amazing features. So, we will be seeing a lot of upgrades of Swift in iOS app development in the upcoming future.
Along with the above-mentioned points, there are a few more considerations for the start-ups to choose Swift over Objective-C, as listed in the below table:
Characteristics Swift Objective-C
Paradigm Object-Oriented Class based Object Oriented
Performance High-performance Not fast-performing due to runtime code compilation
Complexity Requires fewer code lines making it simpler Coding is complex as text strings need many steps for linking different pieces of information
Community support A fast-growing community of supporters Loyal community for 30 years
Memory management Supports the ARC for all APIs Uses the ARC supported only within the Cocoa API
Long-term Outlook Rapidly growing and has a bright future Constant support by Apple
Dynamic libraries support Supports dynamic libraries Doesn’t support dynamic libraries
Readability Clean syntax and better readability Uses many @ symbols, semicolons, lines, etc. to insert new keywords and making it difficult to read

Key Takeaways:

Swift and Objective-C are the two most high-end Apple programming languages. However, Swift supersedes Objective-C in many ways. It is clean, expressive, and intuitive as compared to Objective-C. Also, when it comes to cost-savings, Swift is the apt choice. So, in this competitive business world, start-ups can opt for Swift and build outstanding iOS applications for their success.

Why Angularjs Is the First Choice of Expert Developers for Building Web Applications?

Why Angularjs Is the First Choice of Expert Developers for Building Web Applications?
AngularJS app development company
AngularJS is thought to be the next big thing in the software world. It is undoubtedly one of the most popular and versatile frameworks available today. Introduced by Google in 2009, this framework has progressively proven its worth in the web development market. It helps to develop the most maintainable and stable apps. As a result, the demand for AngularJS web app development has risen from a few years in the software market.
Let us have a look at why this framework is being preferred on a large scale across the world.

What is AngularJS?

AngularJS is an open-source structured JavaScript framework that supports multiple platforms. It is being largely used for developing adaptable and robust single-page applications (SPA). It simplifies front-end development. In this framework, all the commands and functions use code templates which are written in HTML script. The primary purpose of introducing AngularJS was building SPAs and so, it has a strong list of tools that support SPA development. This framework is ideal for the websites in which the content changes dynamically, as per the behavior and preferences of the end-users. AngularJS is also used for developing enterprise web apps, and Progressive web apps (PWAs).

Growing demand for AngularJS web app development

This framework has become a leading choice for developers. It comes with features which let the AngularJS app developers create the most robust and scalable web apps. Being interactive JavaScript framework, it helps in building interactive elements and components of a website. Due to its rich features and attributes, AngularJS has emerged to be a universal solution to web development. It’s difficult to imagine the development of a new-age single-page app without using AngularJS.

Why AngularJS is the best framework for web development?

AngularJS web app development
Google’s support
AngularJS is developed by Google itself and is maintained by dedicated Google developers. There are highly skilled and enthusiastic engineers for assisting if any technical or maintenance issues arise. This framework has a large community support. If you want any suggestions or get stuck with some technical issues, there are many forums to solve your queries.
Two-way binding
Two-way data binding is used in AngularJS and is considered one of the best features of this framework. It supports automatic synchronization of data between the model and the view. One can develop a template with ease for binding different components and models. The modifications in the user interface will instantly impact the application objects and vice versa. For any module changes, user actions or browser events, the necessary patterns are updated immediately.
High-performance
Web developers choose AngularJS because of its robustness, high scalability and ease of maintenance, etc. It is powered by amazing features like filters, directives, content sanitization, form validation, routing, data binding, animations, API client, scope management, form validation, etc. Also, AngularJS supports many tools for providing exceptional performance and outcomes. These help in building high-performing web apps. AngularJS allows producing new elements with the framework.
Simplified Model View Controller (MVC)
AngularJS web app development uses the original MVC model which is a necessary feature for building dynamic web apps. It is a software architectural setup that maintains data, improves the code quality, reduces the complexity and makes the development faultless by dividing logic, UI and process into separate modules. MVC architecture minimizes the need for writing the code.
Better User Interface with HTML
In AngularJS, the user interfaces are built on HTML. HTML is a declarative language having shorter tags and very easy to grasp and follow. The code is lightweight and easy to read and support. The interfaces in HTML are completely well-thought, smooth, organized and structured.
POJO Model
AngularJS web app development makes use of the POJO (Plain Old JavaScript Object) model. POJO provides standard functionalities of JavaScript for object manipulation, so there is no need to add any additional getter and setter functions. The developers need to develop loops of arrays and objects and then reframe or adjust them as needed.
Real-Time Testing
AngularJS has in-built and real-time modules which makes the testing much easier. It supports functional and in-depth testing for every module and allows faster testing of the web apps. 
Security and Responsiveness
Being a very flexible and robust structure, JavaScript framework allows implementing third-party libraries and packages. It helps to build responsive apps.
When there is a new update in the framework, data protection and security of the apps can affect. But AngularJS embeds strict security features and makes the apps highly secure.
Routing
Routing simply means the transition from one view to another. It is a significant feature of single page applications. All the content in a single-page application is present on one single page. So, whenever the users click on a menu, they should not be redirected to a new page. Instead, the content should be asynchronously loaded on the same page while just the URLs change, for rich user experience. AngularJS makes routing easier by making various views for different URLs.
Flexibility with filters
AngularJS is flexible with filters. Filters are used for filtering the data before it reaches the view. These are standalone functions concerned with data transformations. They involve functions like reversing the order of an array, formatting decimal places on a number, implementing pagination, filtering an array based on a parameter, etc. 

Key Takeaways:

AngularJS is a promising framework that is helping businesses to develop interactive and user-friendly web apps. It comes with many controls, services, views, models and directories. As compared to other frameworks, this multi-functional framework reduces the coding part significantly. This ultimately reduces the efforts of developers, while speeding up the development process and reducing the chances of errors. It is a highly flexible framework that enhances productivity and expediency. Using AngularJS framework is a win-win situation for both developers and enterprises.

How to Migrate Chat Applications from Layer to Firebase?

How to Migrate Chat Applications from Layer to Firebase?
Chat applications
This blog post talks about how we migrated from Layer to Firebase and what were the challenges we faced while doing this migration.
We had used Layer Android SDK for integrating chat functionality in one of our new-age messaging apps. This app has features like real-time 1 – 1 and group chatting, audio messages, recalling messages, Facebook messenger integration, payment gateway and military-grade security. The app is about 3-4 years old and is live on play store with a large number of paid users.
Layer provides SDK’s and API’s to implement real-time chat functionality in mobile applications. It helps to implement real-time 1 – 1 chat and group-chat functionalities. Since, Layer had shut down on October 30th, 2019, we had to migrate our chat functionality on this messaging app to Firebase framework by migrating all old users’ data from Layer to Firebase.

Why we Migrated to Firebase?

Firebase provides two cloud-based database solutions that are client-accessible and support data syncing in real-time:
  1. Cloud Firestore
  2. Real-time Database
Cloud Firestore provides better scalability, and performance for web, mobile, and server development from the Firebase framework. It is a cloud-hosted NoSQL database. It can be directly accessed via native SDKs for iOS, Android, and web apps. It is also available in native Node.js, Python, Java, and Go SDKs, along with RPC-based and REST-based APIs.
Cloud Firestore can keep all your data in sync for different client apps with the use of real-time listeners. It can provide offline support for web and mobile for developing responsive apps that can work efficiently despite issues like internet connectivity or network latency.

Migration Steps we Followed

1) Design Firestore Structure Model:
Cloud Firestore is a NoSQL database and it is document-oriented where the data can be stored in documents that are organized into collections. Each document contains a set of key-value pairs. We designed the Firestore database structure as per our old data structure present on Layer.
2) Migrate Existing Data from Layer to Firebase:
To migrate chat data from Layer to Firebase, we created a script which helped to fetch data from Layer using Layer APIs and uploaded it to Firestore as per our data structure. Layer provided data in JSON format and we converted that JSON format data to Collection and Document format.
3) Firebase SDK Integration and Development:
We integrated the Firebase Android SDK to work with Firestore. Then we implemented chat functionality for existing users and for new users as well.

List of Chat Functionalities we Implemented:

  1. Basic Chatting Functionalities:
    • Text
    • Image
    • Video
    • Audio
    • Image with Text
    • Video with Text
    • Audio with Text chatting
  2. Offline Chat Support
  3. Message Features:
    • Search
    • Filter and Sorting
    • Clear All
    • Mark/Unmark
    • Delete
  4. Message Settings:
    • Do not view messages older than a certain number of days
    • Automatically download photos and videos (Wifi only/Wifi and Mobile)
    • Automatically save received photos and videos to photo gallery
    • Set maximum video upload size

Challenges we Faced while Migrating from Layer to Firebase:

1) Designing a Proper Data Structure:
Designing a proper data structure in Firestore was a big challenge as we had to consider the smooth working of functionalities like search, sort, filter, unread message count and also ensure that data is stored in Collections and Documents.
2) Migrating Data from Layer to Firebase:
Converting JSON data retrieved from Layer to Firestore in Document and Collection format was one of the challenges we faced. Also, the size of Layer data was quite big which consisted of text, audios, images, and videos. We did this step-by-step by first migrating data of most active users and subsequently all other users.
3) Syncing data from Firestore to Android App Local Database:
Another challenge we faced was about syncing the migrated data from Firestore to the local Android app for both online and offline support, especially when the user opens the app for the first time after migration. Here in some cases where the size of users’ conversation was large, it took quite a bit of time to sync the data.
Hence to overcome this issue, we synced first just the conversation list and after opening actual conversation, synced messages within that conversation.

The Bottom Line:

Due to Layer shutdown, many applications may be facing issues with their chat functionality and will need to migrate their implementation from Layer to any other platform. We have good experience in migrating chat application.
