What is TypeScript and how is it different from JavaScript?

TypeScript is an open-source programming language built on JavaScript, released by Microsoft in 2012. They initiated its development while working on Bing Maps and the Office programs, as they encountered difficulties with JavaScript and needed a tool that was more suitable for building applications of such scale.

TypeScript is a superset of JavaScript, meaning it can be executed wherever JavaScript runs. While any valid JavaScript code is also correct in TypeScript, TypeScript adds extra features vital for enterprise-level development and is better suited for object-oriented programming.

TypeScript’s features, such as interfaces, type annotations, and strong the type inference system are particularly beneficial for developing, structuring, and maintaining large-scale, complex software applications.

What’s new in TypeScript in 2023?

 

TypeScript 5.0

The goal of this update was to accelerate coding processes and simplify development. This was achieved by refining code and data structures, extending algorithms, and streamlining import-export operations.

The entire codebase underwent restructuring to enable the use of ECMAScript modules. The primary objective was to implement features aimed at reducing package size and enhancing overall performance. One of the key new features is Decorators, which allow for the customization of classes and class members in a reusable manner, simplifying debugging processes and enabling developers to write more concise code.

Furthermore, TypeScript 5.0 includes extended error detection and alert functions, which significantly reduce coding mistakes.

Package Size: TypeScript 4.9 vs 5.0

TypeScript 5.1

By introducing easier implicit returns and allowing completely unrelated types for ‘get’ and ‘set’ accessor properties, the 5.1 update enables developers to work more efficiently and makes code refactoring processes easier.

Another optimization in TypeScript 5.1 involves avoiding type instantiation within object types that don’t contain references to outer type parameters. This reduces unnecessary computations and cuts down on type-checking time in the Material UI’s documentation directory by more than 50%.

 

TypeScript 5.2

The newest update from August includes further enhancements related to ECMAScript modules, such as explicit resource management and object member completions. Previously, TypeScript would provide unrelated completion results when a comma was missing, but from now on, these commas will be automatically filled in by TypeScript.

This update introduces three more important additions: the ability to copy array methods, support for using symbols as WeakMap and WeakSet keys, and clickable inlay hints that provide quick access to parameter definitions.

 

Example for TypeScript development – Caspar Cloud

Caspar Cloud is a case management system built for organisations that are looking after the elderly, sick or other people who cannot take care of themselves. Caspar has a series of highly complex backend functions, including data analysis, statistical reports and automatic server configuration. Since the application was created to be able to store and manage the data of thousands of patients, it was clear that Caspar had to be built creating TypeScript.Caspar Cloud

During the development process, TypeScript helped us detect many common errors during build time due to its embedded static analysis feature, making code refactoring much easier.

If you are looking to build a large-scale application similar to Caspar, or if you would simply like to get more information on TypeScript development, don’t hesitate to contact us through our consultation form or check out our case studies on our website.

 

Summary

Over the last decade, TypeScript has emerged as a compelling choice for enterprise-level application development, effectively complementing the JavaScript language. TypeScript has rapidly gained popularity in the web development community, with support from major libraries and frameworks like Angular and React. There’s also a growing ecosystem of TypeScript-specific packages and resources.

The new updates included speed and performance enhancements, improving code quality and improving readability, reducing development time and simplifying debugging processes. These updates underscore TypeScript’s unwavering dedication to enhancing developer productivity and elevating code quality.

Java

 

The forthcoming release of JDK 21 (Java Development Kit), scheduled for the 19th of September 2023, will bring a suite of 15 innovative features aiming to enhance the efficiency and productivity of Java developers. These upgrades strive to facilitate writing cleaner and less verbose code, thereby streamlining development processes and improving data security. In anticipation of this update, we asked our software engineers at RabIT which new features they are most looking forward to:

 

1. Structured Concurrency

Structured Concurrency has undergone prior testing in JDK 19 and 20, and it is set to be a preview feature in JDK 21 – Meaning you’ll need to turn it on explicitly before you can use it, and the feature might still be reworked before it’s finalized. The main goal of Structured Concurrency is to simplify concurrent programming by enabling the simultaneous handling of related tasks on separate threads and ensuring their proper synchronization.

Concurrent vs. parallel programming

 

By grouping the tasks together logically, this update enhances code stability and transparency, thereby reducing the potential risks of thread leaks and simplifying bug fixing significantly.

 

2. Virtual Threads

Virtual Threads are considered to be one of the most important innovations in the history of Java. In Java 21, if a virtual thread gets blocked or suspended, Java will execute another thread automatically. This new function will empower developers to seamlessly run millions of threads concurrently, without having to alter anything in the codebase itself.

Virtual threads will be a notable enhancement, bolstering processing capacity and speeding up development timelines, and completely revolutionizing concurrent programming.

 

3. Unnamed Variables, Patterns and Classes

Many times, developers have to define a variable, a pattern or a class that they will probably never need in the future again. In Java 21, it will be possible to replace or completely leave out these entities:

From now on, unneeded variables and patterns can be conveniently denoted using an underscore (_), and with the inclusion of Unnamed Classes and Instance Main Methods – two of the most expected preview features – many Java code segments will be shorter and simpler to write, minimizing “boilerplate” code. This latest upgrade enables developers a streamlined approach to optimize code efficiency and maintain a more concise programming structure.

Let’s look at the example of the famous “Hello World” program:

 

Hello World!“Hello World” before Unnamed Classes

 

Hello World!“Hello World” after Unnamed Classes

 

Conclusion

Some of the notable mentions not enumerated here include scoped values, which replace thread-local variables, offering more flexibility and ensuring safer data sharing. Furthermore, the introduction of the KEM API facilitates improved security practices and extends encryption possibilities, among many other useful new features that could be explored further.

Java 21 has the potential to become one of the most significant advancements in the history of the programming language. Anticipated benefits include enhanced security for Java applications and a much more streamlined development process, sparking great interest among our Java developers, who can’t wait for the update to arrive and start working with increased efficiency.

Code quality and transparency are our main priorities throughout each project.

A web application is as good as the framework used to create it. You should choose the best framework for your web development requirement. A framework is a software tool that helps in the creation and maintenance of large projects. All websites these days are easy-to-use and have good User Interfaces due to the frameworks used.

The advantage frameworks provide is that you don’t have to start your project from scratch. Developers use them as a base to add other project-specific features. Resources provided by frameworks include code libraries, utility applications, scripting languages, and other elements.

JavaScript frameworks

There are several frameworks available for web development in 2023. In this blog, we will have a close look at top JavaScript frameworks for Web Development. So, let’s dive straight in.

 

React JS

React JS or React.js is an open-source framework for JavaScript. It can be used for building User Interfaces(UI) and their components. React JS is maintained by Facebook and its wide community. It has become popular due to its ease of use and flexibility.

It makes use of Model View Controller(MVC) architecture with a different table of presentation and data availability. It differentiates itself from other frameworks by having a virtual DOM. Each HTML element functions as an object, and the DOM interacts well with HTML and XML documents.

React has been recognized as a fantastic library amongst front-end tools. It uses JSX coding style, HTML quotes, and tag syntax to create components. Larger components are broken into smaller ones, which can be managed individually. This improves the overall productivity of the developer.

It receives frequent updates making it difficult for proper documentation, and beginners find it difficult to understand JSX. It is meant only for the front-end.

Some of the popular websites using React JS include Skype, Shopify, Instagram, Airbnb, Netflix, and Facebook.

 

React vs Angular

 

Angular

Angular, which was first launched in 2016, was built by Google, and today it is one of the top front-end frameworks. It enables scaling up single-page apps to enterprise-level apps depending on your project requirement.

Angular has an in-built capability to update model changes to views and vice versa. The amount of code required is also less as many features are incorporated as standard.

However, Angular comes with certain limitations. For example, dynamic apps can run poorly due to their large size and intricate structure. It has poor compatibility with search engines and web crawlers, thus affecting the websites’ SEO.

Angular increases the productivity of browser-based apps by quickly changing the content by making use of data binding. This makes it suitable for a dynamic and enterprise-level web application.

Angular has been used by Gmail, Upwork, PayPal, Google, Forbes, etc. We at RabIT Solutions have used this framework for many Web Development  projects as well, as you can see from our case studies on GoodFirms.

 

Angular vs. Ember.JS

 

Ember.js

It is another Open-Source framework that can be used to create attractive user interfaces for websites and apps. It allows you to build complex web and mobile apps, relying on its effective architecture to solve problems.

Ember.js follows the MVVM pattern and creates a testing program for every new entity. Its community of talented developers releases and enhances new features.

The advantage it provides is that it provides tools for native testing and debugging. It also provides two-way data binding, which emphasizes URLs. However, it is a bit difficult to use for inexperienced and not recommended for small projects.

Ember.js offers a ready setup and custom properties to render the page as necessary. It should be used when all-inclusive front-end solutions are needed for a large-scale project.

The platform has been used by LinkedIn, PlayStation, Netflix, Tinder, and Yahoo!

 

Vue JS

Vue JS or Vue.js is a JavaScript framework with greater flexibility for the use of HTML, CSS, and Model-View Viewmodel (MVVM) architecture. It is easy to learn and supported by a large community. To see the apps we have built with Vue.js, make sure to check out our case studies on GoodFirms.

It is increasingly becoming popular and used by brands like Nintendo, Trustpilot, and Behance.

It is small in size and, therefore, easy to download and install. Vue JS can be used to create small and large-level templates. One can easily identify errors, thus saving time and effort. It provides extensive documentation and makes it easy to bind existing applications.

The MVVM architecture makes it easy to handle HTML blocks.

 

jQuery

jQuery is amongst the oldest frameworks for web development, which is still popular. It is a cross-platform library that makes client-side HTML scripting easier. It has an API that works across many web browsers.

It is currently being used by over 41 million websites, including Twitter, JP Morgan Chase, and Bank of America. Event handling, document traversal, Ajax, and animation can be done easily with jQuery.

The advantage it provides is that the DOM is adaptable in terms of adding and removing elements. Sending of HTTP requests has been streamlined, and it allows dynamic content.

It has a few constraints, like slow working speed and outdated APIs of the document object model.

 

Svelte

It is an innovative JavaScript framework that can produce high-performance User Interfaces. It was created by Rich Harris in 2017 and is in the early stages of development. It is different from others as it does not employ a virtual DOM.

Svelte employs a specialized JavaScript Virtual Machine designed specifically for creating UIs. This allows it to be ten times faster than other platforms like Angular and React.

This framework is a good option if you want to create an application with a small team of front-end developers.

It should not be used for large projects as it has a very small community, and you may not get the necessary help.

It has been used by the likes of Philips BlueHive, Cashfree, Godaddy, Razorpay, etc.

 

Backbone.js

Backbone.js is a popular JavaScript library providing web applications with proper structure. It has libraries of enriched APIs that include views, declarative event handling, and functions. It is lightweight as it uses only two JS libraries, i.e., Underscore.js and jQuery.

It can be used for creating single-page web applications and synchronizing multiple aspects. Developers can take the help of Backbone Layout Manager to use predefined perspectives.

Backbone.js has more than 100 available extensions, fewer requests to HTTP, well-organized in-depth tutorials, and stores data in models instead of DOM.

The cons of this framework are that you will have to write more code, and the architecture can be perplexing sometimes.

It has been used by the likes of Walmart, MasterCard, LinkedIn, Pinterest, and Uber.

 

Semantic-UI

It was launched in 2014 and created by developer Jack Lukichthis based on organic language syntax. It is powered by LESS and jQuery. It provides advantages like self-explanatory organic code, rich and responsive UI Components.

Semantic-UI has integrations with React, Meteor, Ember, and Angular. It also provides a variety of themes.

However, its community is relatively small and is not recommended for beginners having limited knowledge of JavaScript. It requires good skills to develop custom configurations.

It has been used by the likes of Accenture, Snapchat, Ovrsea, and Kmong.

 

Web Developer

 

The Bottom Line…

The popularity of JavaScript can be gauged from the fact that almost all web browsers support JS-enabled pages via a dedicated engine. You can use one or more Javascript frameworks for your web development project.

If you are searching for a good framework for your web development requirement, you can bet on JavaScript frameworks. It is flexible, full of features, and efficient at the same time. So, what are you waiting for? Start building your dream Web Application…

The concept of Agile Project Management has spread rapidly and widely all over the world in the last decade. Nowadays it’s considered to be a norm for software development companies to implement the Agile approach in their processes and to employ Project Managers who are experienced in Agile Methodologies.

 

 

Adaptive Agile Project Management – RabIT’s Methodology

We at RabIT Solutions use a slightly modified version of the Agile Methodology that we call “Adaptive Agile”. We have found that this custom methodology is better suited for today’s technology-driven business environment, where the demand for software solutions and the time-sensitiveness of the clients have increased, meanwhile their financial resources have become scarcer.

Being Adaptive Agile primarily means always putting the client first and adjusting all our processes to their specific requirements. We rarely use the same exact methodology in two projects, because we understand that each industry and each business is different, therefore each client has different needs. To satisfy these needs, we do not stick strictly to Scrum or Kanban, but use a mixture of them, tailored to the individual demands of our clients.

Transparency Is Key for Client Success

We fully involve our clients in our projects, not just by asking for their feedback, but also by being completely transparent. We even share our issue tracking systems with them, so they can see which tasks our developers are currently working on. Furthermore, our clients can fully customize our workflow: they can decide how many developers they want to work with, how often we should hold our demonstrations, and they are free to choose from our wide technology stack as well.

We also emphasize the importance of learning from past decisions and implementing our experience in the subsequent stages of the project. Being prepared for unforeseen changes in the circumstances, our project plans never follow a strict structure and a static strategy, instead we plan for multiple possible scenarios and constantly adjust the project plan and scope based on the changing requirements and opportunities. Regular client feedback is the core of our learning process.

 

Summary

In our experience, our Adaptive Agile Methodology is the best solution to create win-win scenarios. The client is always up to date with the current status of the project, always free to come to us with any new ideas, and we always do our best to help them. In return, we get countless learning opportunities. Every new idea, every client feedback and every challenge we face makes us better prepared for the future and better equipped to create maximum value for our clients.

The RabIT Solutions team is excited to announce a brand new service in our portfolio: UX/UI Prototyping.

While one of the biggest advantages of Agile software development is flexibility, adapting to the continuously changing requirements can be very challenging. Based on the experiences we gathered from successfully completing dozens of complex software projects in the last decade, we can confidently say that some modifications on the software products could have been avoided if the idea does not only exist in the participant’s imagination, but they can see it in front of them.

We believe that our new service is the perfect solution. In this article, we are going to introduce what UX/UI Prototypes are and all the benefits they provide for our clients.

 

What are UX/UI Prototypes?

UX/UI Prototypes are not to be confused with UI Wireframes. They aren’t just a series of screens next to each other. UX/UI Prototypes are interactive, clickable samples that exactly resemble how the application will look and function in the future. In other words, they display the visual and the functional aspects at the same time, as well as the interaction between the application’s pages.

The process of creating an interactive prototype

 

Why is UX/UI Prototyping one of the most important steps in the entire development process?

A detailed, well-designed UX/UI Prototype is the common denominator between designers, developers, marketers, and the client. It enables the whole team to be on the same page from the very beginning of the project.

Having such a prototype enables you to try out and see your application as a whole before starting any coding. You can even test your prototype among end users to get early feedback from them, which will help you gain new insights, furthermore highlight any user pain points and usability issues in the earliest stages of the software project.

The most common user pain points

 

To sum it all up…

Making changes during an ongoing software development oftentimes won’t be as simple and straightforward as it might seem at first. Altering existing features or adding new ones will potentially change the whole structure of the application, prolong development time and therefore significantly increase the costs.

If your goal is to develop a high-quality, well functioning software product, it is substantial to be conscious even before the coding begins. With RabIT’s new UX/UI Prototyping service you can get an interactive clickable prototype resembling your future application, thus laying a solid foundation for later stages of development.

While Swift Evolution is currently working on several significant changes to the Swift programming language, Swift 5.8 is primarily a release focused on refining and improving existing functionality. This release includes several exciting upgrades with an emphasis on improving and cleaning up features that are already widely used.

 

iOS Swift

 

Ability to Lift All Limitations on Variables in Result Builders

The latest update to result builders in Swift has eased some of the limitations imposed on variables, enabling developers to write code that was previously considered invalid by the compiler.

In addition, this modification grants users the ability to employ local computed properties and property wrappers within result builders. However, it’s worth noting that their usefulness in this context may be limited.

 

New Function: Back Deployment

Swift 5.8 introduces a new attribute called “@backDeployed,” which enables developers to use new APIs on older framework versions. This is accomplished by embedding the function’s code into the app’s binary and performing a runtime check. If the user’s operating system is recent enough, the system’s version of the function will be utilized. Otherwise, the function’s copy from the app’s binary will be used.

The @backDeployed attribute can only be used with functions, methods, subscripts, and computed properties. As a result, it may be effective for minor API modifications, such as the fontDesign() modifier introduced in iOS 16.1. However, it is not suitable for changes that involve the use of new types, such as the scrollBounceBehavior() modifier, which relies on a new ScrollBounceBehavior structure.

 

Swift Code

 

Implicit Self for Weak Self Captures, After Self is Unwrapped

In previous versions of Swift, developers have had to include the “self” keyword when referencing properties or methods within closures that capture self. This is because the closure holds a strong reference to the object, which can lead to retain cycles and memory leaks.

However, the latest update to Swift (Swift 5.8) takes us closer to removing the need for “self” in closures. In particular, it introduces a new feature that allows for implicit self in cases where a weak self capture has been unwrapped. This means that developers can now access properties and methods of the enclosing instance within a closure without explicitly referencing “self,” as long as the capture is declared as “weak” and unwrapped before use.

This is a major improvement for Swift developers, as it simplifies the syntax and makes code easier to read and write. Additionally, it helps to prevent common memory management issues that can arise when working with closures that capture self.

 

Concise Magic File Names

The latest Swift 5.8 update modifies the #file magic identifier to follow the format Module/Filename, such as MyApp/ContentView.swift. 

Previously, the #file identifier contained the complete path to the Swift file, such as /Users/twostraws/Desktop/WhatsNewInSwift/WhatsNewInSwift/ContentView.swift, which was overly verbose and made the code harder to read.

The Swift evolution proposal for these changes states that the update will improve the binary size and execution performance, leading to further enhancements in Swift 6. 

 

iOS Swift 5.8

 

Open Existential Arguments to Optional Parameters

Swift 5.8 expands upon a feature introduced in Swift 5.7, which allows developers to call generic functions using a protocol. This update addresses a small but frustrating inconsistency in the previous version of Swift: while Swift 5.7 permitted calling generic functions with protocols, it did not allow this behavior with optionals.

The new update in Swift 5.8 addresses this inconsistency by extending the protocol-based approach to optional types. This will allow developers to use protocols to call generic functions that accept optional types, making the language more consistent and user-friendly.

This update is exciting for developers because optionals are a fundamental concept in Swift, allowing developers to handle situations where a value may be missing. By extending the protocol-based approach to optionals, Swift developers can now use the same generic functions with optional types as they do with non-optional types, reducing the need for workarounds or additional code.

 

New Support for Collection Downcasts in Cast Patterns

The latest update in Swift addresses a small but potentially frustrating inconsistency that could occur when downcasting collections. Specifically, in certain circumstances, Swift would not allow developers to downcast a collection, such as casting an array of objects belonging to ClassA to an array of objects belonging to a different class that inherits from ClassA.

This update in Swift resolves this inconsistency and makes it possible for developers to perform downcasting on collections in all scenarios. This means that developers can now more easily work with collections of objects that belong to a specific class or its subclasses, improving the flexibility and functionality of their code.

 

A New Era of Swift

Swift 5.8 introduces a range of updates and improvements that build on previous releases and enhance the language’s functionality and flexibility. From improving result builders to addressing inconsistencies in downcasting collections, these updates are designed to make the development process smoother and more intuitive. 

With these updates, Swift continues to demonstrate its commitment to innovation and user-centered design, providing developers with the tools they need to create powerful, efficient, and user-friendly applications.

Spring Boot 3.0 has brought numerous exciting features and updates to the market. Late last year, Spring Boot 3.0 became the first major upgrade in over 4.5 years. With more than 74% of Java developers using Spring Boot, the upgrade is having impactful changes across the industry. 

 

What is Spring Boot?

Spring Boot is an open-source extension of the Spring Framework that hosts third-party libraries that help developers jump-start applications for production. It allows developers to focus on the application’s business logic rather than configuration, making the tool an industry favorite. 

The tool was created by Pivotal Software and has been upgraded approximately every four years. The first version, Spring Boot 1.0, was released in 2014, Spring Boot 2.0 in 2018, and now Spring Boot 3.0 in November 2022. 

 

Spring Boot

 

What’s New With Spring Boot 3.0

Spring Boot 3.0’s launch came with an abundance of new, innovative features. Below are some of the most significant changes happening on the network:

 

1. Java 17 Baseline with Java 19 Support

With the latest upgrade, Java 17 is now the baseline needed to use Spring Boot 3.0. The newest version will not work with JDK 8 or 11, so developers will need to update to JDK version 17 or newer. Fortunately, Spring Boot 3.0 is also tested with JDK 19, allowing developers to use the most advanced Java JDK software. 

2. Jakarta EE 9

One of the most important upgrades is the change from Java EE to Jakarta EE9. Because the package namespace changed from javax.* to Jakarta.*, users will need to adjust all imports in their code whenever using classes from Java EE directly. 

Users should also understand that when using external libraries that depend on Java/Jakarta EE, changing the namespace will be crucial for avoiding coding errors. 

3. Log4j2 Enhancements

Another exciting feature for developers is the introduction of new Log4j2 extensions, including the following features. 

Profile-specific Configuration

The <SpringProfile> tag lets developers create custom configurations based on active Spring profiles. 

Environment Properties Lookup

With Spring Boot 3.0, developers can look up properties from Spring Environment with their Log4j2 configurations. 

Log4j2 System Properties

Log4j2 can support numerous System Properties that developers can use to configure various items. 

4. Observability with Micrometer and Micrometer Tracing

Spring Boot 3.0 has introduced Spring Observability, built upon Micrometer and Micrometer tracing. Now, developers can record various application metrics and provide tracing support to tools such as OpenZipkin and OpenTelemetry. 

5. GraalVM Native Image Functionality

Native Image support was one of the most anticipated changes with the upgrade. With Spring Boot 3.0, developers can convert applications directly into GraalVM native image. Native image enables fast application start times, resulting in sizeable memory consumption improvements. 

 

Spring Boot

 

Upgrading to Spring 3.0

Spring Boot 3.0 is an exciting upgrade that will unboundedly improve development times and enhance application abilities across the board. While the above list highlights the upgrades of the tool, users can get the full release notes on Spring’s website. 

Remember, before upgrading to Spring Boot 3.0, it’s recommended to switch over to at least Java 17 and upgrade Spring in increments rather than skipping install versions.

Today, companies of all shapes and sizes are starting to use digital technology to bypass the limitations of the physical world. The power of digitization of business processes can be recognized as a catalyst not just for driving enterprise scale and efficiency, but for helping to deliver focused innovation with much greater precision and speed.

New advances in this field also allow them to release their products to the market faster, to reach the right customers, while offering a near perfect user experience.

We’ve already gone into the details about reasons your company might benefit from the digitization of business processes in an earlier article. Just to list a few, you might need to digitize in order to:

  • answer disruption in your industry,
  • improve everyday efficiency,
  • improve customer/user experience,
  • utilize new channels to their full potential,
  • extend services to mobile users,
  • shorten your supply chain,
  • utilize emerging new technologies, etc.

In this article we are focusing more on the ways you can validate your approach to the digitization of business processes or test specific concepts both internally and externally.

 

Ways to Validate the Digitization of Business Processes

1. See how other industry players did it

It is possible that your idea is not unique at all. Through a simple online search, you can discover products that might have germinated from a similar idea-seed. It is better to think of a new idea if your concept does not offer something extra special or improves the way of doing things.

 

2. Present the concept to employees early

If you are planning to introduce a new digital tool into your current workflow, it is highly beneficial – if not essential – to hear the perspective of the employees who will actually use it to carry out their day to day work tasks. This can be done in a similar way as user acceptance testing with a customer-facing MVP.

It is also recommended to simply present the concept of the new solution before starting any development in order to include the users’ ideas into the software requirements and design. This may save you a substantial amount of money spent on fixing/rewriting counter-intuitive or inefficient software features.

 

digitization of business processes

 

3. Hypothesis Testing

You can assess the viability of a new digital solution via hypothesis testing methodology, without developing a product prototype. You can use either a Wizard of Oz MVP or a Concierge MVP to validate your business idea.

Concierge MVP: You provide the value proposition manually to a small group of test users, without involving any technology. You perform the service following the same steps as the final product.

Wizard of Oz MVP: In this method, you make the test users believe that the new digital solution is already able to complete a certain task. They see the working front of your product (this is often solved by using clickable design wireframes), while there is no actual code running in the background yet.

 

4. Single-Feature MVP

Single-feature minimal viable product (MVP) enables you to test one core aspect of your digital solution. You give your end-users this one-core-feature product to use, to get early feedback. It is one of the easiest methods by which you can validate or invalidate the digitization of business processes, and you can do so on a shoestring budget.

Now that you have a basic idea about how to validate a concept, you can get creative and start presenting to your employees to find out first hand if your idea really has merit or not.

 

Summary

Digitization of business processes offers some important new changes and opportunities for modern enterprises, big and small alike. Leadership should be encouraged to always question the traditional way of doing business, and periodically rethink the entire company in order to succeed in this rapidly changing environment.

Other than opportunities, the digital revolution will definitely bring many new challenges as well. This is why it is more important than ever for you to follow latest trends and developments not only for your company, but for your entire value chain.

Java has held a special place in the hearts of many developers since its release more than two decades ago, including our own. Since it is such a mature, widely-used technology, there are also plenty of great automated Java code review tools to choose from today.

According to last year’s Stack Overflow Developer Survey, it is still among the 5 most popular programming languages.

 

java code review tools - java popularity

Source: Stack Overflow

 

Also, according to the TIOBE index, Java is still the number one programming language today, just barely surpassing C. The index is calculated using the number of skilled engineers world-wide, courses and third party vendors, as well as queries in popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu.

 

Briefly about code review & analysis:

Code reviews are processes where software developers and testers check if an already written source code complies with coding conventions and standards.

Apart from manual code reviews, static and dynamic code analysis can also be conducted with the help of automated tools.

Static code analysis tools examine the source code without executing it. Dynamic analysis is conducted while the code, or a part/unit of it (for example unit or integration testing) is being run.

 

Why are code reviews important?

Poor source code quality causes plenty of headaches, overworked days and sleepless nights for developers and product owners alike. Planning and conducting code reviews is often ignored by management, usually leading to long-lasting negative effects on development efficiency and even the whole business.

To briefly summarize, if the quality of the source code is left to deteriorate:

  • adding new features becomes increasingly difficult, while potentially breaking existing ones in the process
  • bug fixes take up more of the team’s time, missing deadlines and prolonging crucial updates
  • onboarding new developers requires more time if the code base is hard to read and understand
  • poor source code quality can also negatively impact users’ perception of the product, and the whole organization
  • future development estimations also become less accurate if it’s impossible to predict how long it takes to add new features without breaking existing ones.

For anyone who is interested in reading more about the effects of low-quality code, we’ve dedicated a whole article to this topic not long ago.

 

 

What is the basis of our recommendations?

Java has been our go-to technology for many custom software development projects over the last decade. It is, in fact, our most frequently-used programming language to date.

We’ve encountered many Java-based software projects throughout our work that were struggling to move forward because the source code had gotten so unstable that it was difficult, or straight-up impossible to develop further.

We were only able to stabilize these software products and continue feature development after running a whole assortment of tests and completing a ton of code refactoring work. The following recommendations are based on the experience gained throughout these projects.

 

 

We recommend using these Java code review tools:

 

Checkstyle is a static code analysis tool used in software development for checking if Java source code complies with coding rules. It basically automates the lengthy process of checking code and helps Java developers enforce coding standards.

It can find anything from class or method design problems to code layout and formatting issues. You can find the complete list of checks here.

Checkstyle has a large number of plug-ins as well that let teams integrate continuous code checks into their projects.

 

PMD or Programming Mistake Detector is an open source static source code analyzer that reports on issues found within application code.

The tool is used to detect common mistakes made in the code by using the standard rules or defining custom rule sets. Using PMD, teams can detect common flaws around naming conventions, unused variables and parameters, empty catch blocks, unnecessary object creation, etc.

PMD has plugins for JDeveloper, Eclipse, jEdit, JBuilder, Maven, Ant, Gradle, Jenkins, SonarQube and many other tools and IDEs.

PMD also contains CPD (or the Copy/Paste Detector), which is used to detect duplicate code in. We find this to be a very useful add-on, as duplicate code can be quite hard to find, especially in a large project.

Eliminating duplicated blocks of code is important for a number of reasons, like removing unnecessary grunt work during refactoring. It puts a lot of pressure on the developer to remember where they are located and edit them when making significant changes on the code base.

Also, if they are working in a team, developers otherwise have no way of knowing where other team members inserted duplicate code segments. This can make future development and maintenance tasks much more complicated.

Apart from Java, it can also be used for C, C++, PHP, Python, JavaScript as well as other programming languages.

 

JetBrain Space Java code review tool

JetBrains Space is a new unified platform that offers a complete toolchain for the software development pipeline, as well as tools for team collaboration at companies of any size.

It removes the silos that are often inherent to organizations, helps individuals and teams be more productive, and makes software development and collaboration more enjoyable.

Apart from offering most features as other java code review tools, developers can also host Git repositories, review code, automate CI/CD, store and publish packages, develop remotely with cloud dev environments, manage issues and documents, and communicate in chats – all in one place.

Space is available on the web and as a mobile app for iOS and Android.

SonarQube is an open-source code quality inspection platform. It is used to perform automatic reviews with static analysis of code to detect bugs, coding errors, and security vulnerabilities.

The platform offers reports on duplicate code blocks, coding standards, unit tests, code coverage, code complexity, comments, bugs, etc.

It is a popular choice for analyzing Java code, especially for teams using Maven and Gradle, but others can also use it by manually providing bytecode to the analysis.

SonarQube currently supports a total of 27 programming languages including Java, C#, PHP, JavaScript, TypeScript, C/C++, Ruby, Kotlin, Go and Python for example.

 

JArchitect is a static analysis tool specifically meant for Java code. It supports a large number of code metrics like number of parameters, variables and lines of code, cyclomatic complexity, afferent and efferent coupling and so forth.

JArchitect also allows teams to expose architectural flaws, visualize and manage dependencies using directed graphs and a dependency matrix. This is only a few of the many useful features the platform can provide.

 

JUnit is a unit testing framework for the Java programming language. For reference, unit testing is a method for evaluating the performance of individual units, components or modules of the source code.

The framework allows teams to write and run unit tests for Java 8 and above. Its latest version, JUnit 5 is composed of several different modules:

  • The JUnit Platform – responsible for launching testing frameworks on the JVM.
  • JUnit Jupiter – a module that includes new programming and extension models for writing tests.
  • JUnit Vintage – which supports running JUnit 3 and JUnit 4 tests on the platform.

JUnit is the most popular unit testing framework for Java development projects, and is often listed among the most commonly included external libraries in general.

 

JaCoCo is an open-source toolkit for Java, used for measuring and reporting code coverage.

The term ‘code coverage’ is used in software development to define how much of a program’s source code is covered by a testing plan.

We are including this as sort of an honorable mention, as some other tools, IDEs and platforms already include JaCoCo as a plug-in. A few examples of these are:

  • SonarQube
  • Eclipse
  • Jenkins
  • Netbeans
  • IntelliJ
  • Gradle
  • Visual Studio

 

 

Summary

 

Of course, these recommendations are purely based on our own experience and preferences.

Which Java code review tools you’ll choose for your own development projects should be based on a fair amount of testing and their compatibility with your technology stack of choice.

If at any point you find yourself in need of another set of eyes during code reviews, don’t hesitate to reach out to us with your questions.

Thanks for reading our article!

Startup & MVPBY RabIT Solutions

Introduction

Many of us dream about becoming self-made successes, entrepreneurs to finally free ourselves from our 9-5 jobs and turn our dreams into a reality. Today, the internet is littered with success stories about people who have already made it big and became millionaires, hundred millionaires, billionaires even.

The path to achieving breakout success sounds simple when you hear the story of someone who already has it all figured out. However, finding the right way is much harder if you are starting from scratch. A startling amount of entrepreneurs never achieve their ultimate goals. According to statistics, only 30% of small businesses make it past their 10th anniversary.

To improve the odds of success, more and more entrepreneurial journeys start out with a simple Minimum Viable Product (MVP).

 

What Is a Minimum Viable Product?

The term was introduced as one of the core principles of the lean startup methodology.

An MVP is the initial version of your product that only has the core features that are essential to solving an existing problem for your prospective customers. Your minimum viable product helps you gather important feedback and estimate market interest from the earliest stages of your business. More complex features are only added in later iterations, based on the received user feedback and the development of market demand.

A minimum viable product can be a simple web or mobile application, website or a single landing page.

MVP Benefits

A minimum viable product enables you to:

  • test a product hypothesis with minimal resources
  • accelerate learning in your organization
  • reduce necessary development hours
  • reach your actual market as soon as possible
  • decrease the risks of investment
  • establish your brand to users quickly

 

Researching and Verifying the MVP Idea

Verifying the business idea itself is a crucial step that absolutely must come before you rush into any kind of development project. You can significantly decrease the risk of investment by double checking if there is enough interest on the market for your solution.

Not even a company like Google could get away with selling a product that had no clear product-market fit (ehm… Google Glass).

Your new product or service has to offer a much needed solution for a need (or problem) that is being underserved by competitors or not served at all by anyone. You also have to make sure that the problem is pressing enough to justify the price of your solution in the eyes of potential customers.

A good cautionary tale here could be Juicero, Silicon Valley’s smart juicer that squeezes disposable packets of liquified fruits, vegetables, and other ingredients into cups. Even with 4 funding rounds and close to $120 million of total funding, they couldn’t justify the $400 price tag for a web-connected device the basically empties a drink from a bag. The company went bottoms up less than 4 years after its founding.

Know what it costs to deliver your product (materials, rent, salaries, etc.) and to acquire customers who will pay to use that product (CAC – customer acquisition cost). All these costs have to be included in your pricing as well. While breaking even helps you consistently pay the bills, it won’t be enough to become a top player in your industry. Be sure that your costs are still reasonable to customers even after adding your profit margin.

According to smallbiztrends.com, only 40% of small businesses are profitable, 30% break even and 30% are continually losing money.

The initial verification usually isn’t enough to prove that your business will be sustainable on the long run. That part will be up to your actual MVP.

You can get really creative with your idea verification methods. Use every tool at your disposal to measure the buzz around your idea. These examples are accessible to everyone for little or no expense:

  • Google search
  • Google Trends
  • Landing pages
  • Explainer videos
  • User testing

Start by identifying your key customer profile and creating buyer personas. This should help you visualize your ideal client base and customize your marketing messaging to better fit their specific needs. Do your best to reach out to as many people who fit this profile as you can.

What does the minimum viable product development process look like?

Minimum viable product development has to result in a product that delivers real value to its users is a complex process that may vary depending on your industry, product type, user base and so on. For the sake of clarity, we will break the MVP development process down to the following steps:

I. Setting a hypothesis

Hypothesis-based decision making helps you avoid basing your product idea on false assumptions and prejudices.

While it might seem like a billion-dollar idea to produce a smart salt shaker with Bluetooth technology, it can’t hurt to double check first. Just to be sure.

Using this method to come up with a business idea should guarantee that it will be based on real-life demand. A good hypothesis must be:
– easily testable,
– clear and measurable,
– either clearly true or false.

The most simplified template for such a hypothesis would look something like this:

 

If [cause], then [effect], because [reason].

 

Example: If we develop an app for broadcasting nostalgic content for people born before 1970, then we can get 50,000 people to sign up for a free trial by the end of 2020, because research data shows us that 80s and 90s nostalgia is very captivating to our target audience.

Once you have gathered sufficient evidence proving that your hypothesis is true, you can start planning product development with much greater certainty.

II. Selecting technologies

Minimum viable product development can be done with any modern-day programming language. However, it is crucial that you decide from the start whether or not you are planning to develop an MVP, or a full-fledged software product. If you choose the MVP route, you should go with technologies that are highly flexible and scalable.

Due to the evolving nature of an early MVP, developers need to be able to easily make changes to the source code at all times. By choosing modern and frequently updated tech in the planning stage, you can make your team’s life much easier when it comes to implementing these changes.

You should always choose the technology your team is most comfortable with. If you are open for suggestions though, here are a few pointers:

Micro-service architectures carry great benefits for MVP development. These micro-services are comprised of small modules that communicate with each other, and sometimes with the user as well. By using modular builds we are able to decompose an application into different smaller services. This makes the application easier to understand, develop, test and become more resilient to changes in the architecture itself.

Thanks to the independently functioning modules, multiple autonomous teams can work on development at the same time. This alone can help speed up the project significantly.

 

monolithic vs microservice minimum viable product

However, if you are developing a really minimalistic MVP with a small team, and scalability is not a top priority yet, we would rather recommend using monolithic architecture. Its main benefits are faster development and lower hardware requirements.

Also, the developed application will be self-contained and independent from other computing applications. Later on, if scalability becomes important and more developers join the team, it should be separated into micro-services though.

A lot of developers would disagree with using monolithic architecture for MVP development today. It may be falling out of popularity, but we believe there are still cases where it’s the right call. Instead of selecting the most popular option, this decision should be made according to product strategy and technical requirements.

Language-wise we ourselves prefer to use Java, since that is what our team has the most experience with. We have also started using Go (or Golang) recently, thanks to its speed and ability to produce small, static binaries. These really come in handy if you are working with micro-services.

Regardless of the selected technologies, you can build a top-quality MVP if you invest the time and energy into planning your project properly. You can only make your development team’s life easier if you choose a modern and frequently updated language.

One of the most common pitfalls of this process is not having a clear vision of a specific end goal and focus on the most critical features.

 

 

III. Product feature development

Choosing these key features may sound easy enough, but is not always so straightforward. This is why you needed to do all that research first, and verify your concept before moving on to product development.

If you already have a good understanding about your market, the development process itself should look something like this:

  1. Define product requirements
  2. Plan and assign development tasks
  3. Feature development and testing
  4. Live release
  5. Product evolution (repeat 1-4)

 

Try to look at product development as a cycle instead of a linear process. In this example, the live release doesn’t happen when development is finished, it happens when the MVP functions on a satisfactory level. Your product still needs to evolve through future iterations. Current features will have to be tweaked or scrapped if necessary, new features might have to be added, etc. In some cases, development may continue throughout the entire product life cycle.

Have you heard about the location-based iPhone app called Burbn? It allowed its users to check in at particular locations, plan future check-ins, earn points for hanging out with friends, and post pictures of these meet-ups.

The app wasn’t doing too well after its initial release. After analyzing their users’ activity more closely, the creators found out that people were mostly using Burbn to share photos. They weren’t using the check-in features at all. The app was just too complicated, and came with a lot of features that users found unnecessary.

The team finally decided to act on their data, focus on the photo-sharing feature and throw out everything else. This app is called Instagram today.

This is a good example for why it is essential to involve real users in the development process from the early stages.

Our team places a great emphasis on product evolution as well. Here is what the development cycle usually looks like for us:

IV. Testing

Continuous testing is one of the key principles of validated learning, which is used to mitigate the considerable risk of launching a new product. There are over 30,000 new consumer products released each year, and 95% fail, according to Harvard Business School professor Clayton Christensen.

We recommend that, apart from testing software functionality, you should also start usability testing as early as possible. This is important because even a perfectly functioning product can be misinterpreted by users due to confusing layouts, unclear documentation or faulty user interface design.

Normally, software doesn’t get released until it is complete and working just as intended. Although a minimum viable product is intentionally released in an incomplete state, it is still expected to work flawlessly in the hands of users. It basically has to be much lighter than a complete software, but still has to seem just as stable. This requires continuous feature testing in every development phase.

The development team must include testing during and between sprints (iteration periods in continuous Agile software development cycles). Sprint length and frequency usually varies depending on client needs. For some clients we test each development task individually, others only require testing at the end of a sprint. We always use the same platform for this purpose that we use for development as well.

Minimum viable products are beneficial long-term, in part because the high user expectations result in a high-quality product that is thoroughly tested down to the smallest detail.

 

V. Collecting data and analyzing a hypothesis

The point of minimum viable product development is to collect user feedback, analyze this data and finally act on it through future product iterations. As your prototype becomes stable enough to be put into the hands of real users, you must also have the necessary data collection channels and tools in place.

To identify your key audience and focus on their needs as accurately as possible, you will need to measure their demographic (age, gender, location, etc.) and behavioral data (device usage, interests, preferences and such).

Remember that all data collection practices on your website and applications must be done with consent from the user.

The most widely-used data collection methods are:

1. Third party data collection services already available on the market

There are a number of ready-to-use tools out there such as Google Analytics, Crazy Egg, Hotjar, Optimizely and others, which can help you collect useful behavioral data about your website and apps.

Unfortunately, these tools may have some drawbacks for clients in EU countries. GDPR regulation now limits what types of data can be collected and under what circumstances. This means that you probably won’t be able to use them to their full potential.

You can also gather useful data from the App Store or Play Store if you are planning to release a mobile app.

2. Built-in custom data collection features

With integrated monitoring features you can measure and analyze almost any element of your product at this stage. You can keep track of which software features people are using, where and when they are using them.

We usually recommend to our clients to build a reporting page where they can organize all relevant data and visualize it so it can be presented to the whole team.

Again, it is crucial to remember to disclose all information about your data collection and management practices in your privacy policy.

Also make sure that your methodologies are in line with GDPR regulation for EU countries.

3. Surveys that ask users for in-depth feedback directly

E-mail and pop-up surveys are still one of the most useful ways to collect information about user satisfaction and recommendations. You can use them to get answers you can’t find by just monitoring behavior.

Be careful not to annoy your users with too many such requests and ruin their user experience though.

 

VI. Launch

Your minimum viable product is ready for launch when all the minimum requirements are fully developed. The product must be of satisfactory quality and without any critical usability errors by this point. You should know whether or not this is true from the results of previous testing.

Product testing and evolution doesn’t stop after the minimum viable product phase either. It is up to your product team now to listen to your customers, find ways to deliver even more value to them and integrate the necessary changes through future development iterations.

Remember, if you get your finger off the pulse of the market, you can quickly lose touch with your customers’ needs and allow competitors to swoop in.

Keep in mind, that developing a flawlessly working app with beautiful design does not automatically make it successful. You also need a strategy to acquire and continuously grow your initial user base. This topic deserves a whole article of its own.

Be sure to remember that a half-completed app with a steadily growing user base is always more valuable than a 100% finished application that nobody uses.

 

Summary

Successful minimum viable product development requires careful planning from the early stages, and close monitoring throughout the development process.

While there can be a lot of money involved later on, getting rich fast must not be the only motivation for minimum viable product development. If your new product truly helps people improve their lives, or the way they work, your chances at success are already much higher.

Be careful not to rush into development with only an idea. Do your best to back it up first through market research and concept testing.

Once you’ve decided that you want to develop an MVP version, stick to this decision throughout the development phases. Pay close attention to how your customers use the product or service, and plan each following evolution stage accordingly.
