An Introduction To MERN Stack

A technology stack refers to the framework of technology services that are used to build, run and maintain a single application. Also called as technology infrastructure, solutions stack or data ecosystem, a technology stack comprises of all the languages and coding frameworks that make up a successful web application.

Let us take Facebook for example. Facebook as an application makes use of a combination of programming languages and frameworks like HTML, CSS, JavaScript, ReactJS and PHP. Thus, Facebook’s technology stack refers to these languages that make up the application.

1. Introduction to MERN Stack

There are many technology stacks used for web and application development. One of these tech stacks is called the MERN stack. Built on four primary software components, MongoDB, ExpressJS, ReactJS and NodeJS, the MERN tech stack is a comprehensive web development framework used by developers to create high-quality websites and applications.

2. Components of MERN Stack

The four main components of the MERN stack are as follows:

• MongoDB: The database component of the MERN stack, this document-oriented language is used to store, as well as retrieve, application data.
• ExpressJS: The backend component of the MERN stack, this features a framework built over NodeJS, which makes use of NodeJS structures and functions to create the backend framework for websites and applications.
• ReactJS: The library component of the MERN stack, which is used to create UI components for the development of a user interface on a web page.
• NodeJS: The Javascript runtime component of the MERN stack, which is used to run JS commands on a machine, as opposed to running them on a browser.

3. Advantages of MERN Stack

• Single Source Code: One of the main benefits of the MERN stack is that it utilizes a single language for both the server and client-side codes, frameworks and structures. Every single line of code in the MERN stack is written using Javascript. This makes the stack easy to learn and master.
• Absence of Context Switching: With technology stack using multiple languages; it becomes necessary to resort to context switching across multiple tiers. However, since the only language used in the MERN stack is Javascript, context switching is no longer considered a necessity. It also becomes easier to interface multiple layers of code with just one language in use.
• Excellent UI: ReactJS stands above AngularJS when it comes to offering the best UI rendering, as well as UI performance. The extensive library of UI tools that it is, ReactJS allows programmers to build application easily by organizing code the way they want. This quickens the development speed while improving UI performance and rendering considerably.
• Enhanced Database Functions: The addition of MongoDB to the MERN stack means a powerful database that offers higher scalability and speed. When combined with server-side and client-side Javascript code, MongoDB and the MERN stack, as a whole, contribute to the creation of highly efficient websites and web applications.

4.Prerequisites for a MERN Stack Developer

If you want to become a MERN stack developer, here are some of the prerequisites you would require:

• Extensive programming knowledge in Javascript, as well as basic knowledge of other programming languages, such as HTML and CSS.
• Working knowledge of building web applications, including workflow, framework and architecture.
• Working knowledge of frameworks and components related to ReactJS.
• Working knowledge of MongoDB and ExpressJS.
• Basic understanding of the client and server-side processes.
• Basic understanding of motion UI.

Will Chatbots Change The Customer Experience-The Future Of Customer Experience?

When customer experiences hinge on more than just customer service, Chatbots help you rise to the occasion. Often supported by Artificial Intelligence, the software is built to converse with human users over the internet via websites, messaging programs, apps and telephone. Chatbots analyze user requests and respond intelligently, the way a human would.

Chatbots are emerging as the norm, helping drive customer engagements in conjunction with classic touch-points, such as social media, telephone, email and more. If Global Market Insights is to be believed, the global Chatbots market would be well over $1.3 billion by 2024. Per another study, 53% of service firms plan to incorporate Chatbots within the next 18 months.

Why and how Chatbots are changing the customer experience? Let’s discuss, in detail.

1. Natural Language Processing:

Thanks to the headways in Artificial Intelligence, Chatbots are getting more sophisticated with better abilities in understanding conversations and making decisions. More specifically, Natural Language Processing (NLP) is being leveraged to help bots to discern what the user is saying or typing, and respond more sharply. As NLP evolves, Chatbots are getting adept recognizing the conversation’s context, handling dialogue and tailoring a response based on the conversation.

2. Drive Lead Generation:

Let Chatbots drive leads, and help grow your customer base and profits. First, these programs engage in early support interactions with users, creating more qualified leads to be capitalized by sales reps later on. Secondly, when chatbot directs a customer to your website, sorting out their preferences is easy and quick. This, in turn, helps you create and deliver customized and effective marketing messages. Imagine sharing new offers and coupon codes to attract sales.

3. Enhance Capacity:

With Chatbots, you automate certain cumbersome tasks like providing the same information to different users redundantly. That frees you and your staff to concentrate on core competencies and other lines of business integral for growth and success. Data-driven Chatbots generate a huge amount of data, which can be analyzed to identify loopholes and ways to plug them. Plus, the software helps train new employees, bringing them onboard quickly and effectively.

4. Cut Down Operational Cost:

One key factor why Chatbots are the new interest zone in customer service is their cost-efficiency. Chatbots are capable of engaging multiple users simultaneously, relieving you from investing in a sizeable customer support staff. These programs can scale to your present and future needs, saving money that otherwise would be required for additional programming.

5. Minimize Errors:

Humans are prone to error but Chatbots aren’t. They leverage an enormous amount of data at their disposal to provide accurate information to the user, day in and day out. Any discrepancy in providing information related to policies, FAQs and more are eliminated outright. Unlike humans, a program doesn’t let emotions override decisions, have a bad day, and work 24/7/365. Plus, feel free to audit the chat logs for reasons of regulations if/when needed.

6. Complete Customer Satisfaction:

When customer satisfaction is a priority, Chatbots make sense. Chatbots are programmed to provide answers to customer queries quickly and smartly, round the clock. That goes well with millennials who lack the patience for long waits and misinformation. The user is likely to stick with your brand when your chatbot is providing real-time assistance across the buying journey. Plus, the data retrieved from Chatbots helps you to know customer preferences, and tailor services accordingly. That leads to high customer satisfaction and retention rates.

7. Multipurpose:

Versatility is another trait so inherent in Chatbots. They adapt to different business functions, from customer service and data gathering to employee training and on-boarding. Within the customer service domain, they are being utilized for labor-intensive tasks, such as Tier-1 support and customer satisfaction representation. Plus, chatbot belittles language barriers with customer support in multiple languages, ensuring seamless digital support in different regions.

Native App Vs. Hybrid App:-Which Platform Is Best?

Over 3.5 billion people use smartphones worldwide. Each user spends roughly 162 minutes a day on their smartphones. About 90% of their smartphone time is spent in mobile applications. The stats suggest how important mobile development is for businesses, big or small.

There’re two approaches to mobile app development, native and hybrid. Each option has its share of pros and cons. Read on to know how they fare against each other on key parameters.

1.Native App vs. Hybrid App Comparison:

A native app is software developed for a particular operating system, think Java for Android and Swift for iOS. The software is developed in line with technical and user experience requirements of the given OS. This translates into faster performance and a more immersive user experience.

Built on the native language, these apps look and feel like the native apps of the device, and can achieve unity with the device’s in-built functions, such as camera, GPs, adress book, and more. Native apps are usually created for Android and iOS, the two operating systems with 99.6% share of the global OS market. Both OS offers advanced tools for easy native app development.

2.Apple iOS Development Tools:

• iOS Software Development Kit (SDK) with Cocoa Touch UI framework integration
• Integrated Development Background (IDE) – X-Code
• Beta testing software – Test Flight

3.Android Development Tools:

• Android SDK with Android IDE
• A set of predetermined Android components – Jetpack
• An all-inclusive development platform – Firebase
• A complete set of command line tools

Once the app is ready, it needs to be submitted to the Google Play store for user downloads.

As the name suggests, hybrid apps are built using certain elements of both, native apps and web apps. For the uninitiated, web apps are websites that mimic apps in look and function but unlike apps, they aren’t installed on the device. Instead, you access them via internet browser.

Hybrid apps are regular web pages created for Android, iOS or any other specific operating system through HTML, HTML5, CSS, JavaScript, and other web technologies. The software is used in a native container wrapped in WebView to help access the device’s hardware features like camera, address book, GPS, and more. A few popular hybrid app development frameworks include React Native, Corona SDK, Flutter, Iconic, and Mobile Angular UI among others.

4.Native App Development Benefits:

Native apps stay significant for the host of benefits they bring forth.

• Performs Better: Native apps outperform the hybrid apps. They are built using the device’s native framework, making them faster and more efficient and user friendly.
• Safety Ensured: When data security is a priority, native apps make sense. Developers find it easy to make these apps secure for the enterprise, finance and other sectors.
• Accessible Offline: Native apps support offline modes. They are, thus, easily accessed, regardless of whether the internet connection is poor or even unavailable at all.
• Instant Access to Features: When iOS and Android unleash new features, native apps are better equipped to imbibe them more readily minus the hassles of plug-ins.
• Fewer Bugs throughout the Development Phase: Native apps don’t require a cross-platform tool and hence, encounters fewer bugs throughout the development phase.

5.Hybrid App Development Benefits:

From Facebook to Netflix, all top apps are hybrid apps. Here’re a few plausible reasons why.

• Economical and Easy Development: In hybrid app development, the code is written just once. That means significantly lower development costs and time than native apps.
• Speedy Performance: Hybrid apps leverage web technologies for speedier performance. An app can run both ways, as a website and as a Progressive Web App on any browser.
• Native Experience with easy Backend: Hybrid apps rival native apps when it comes to connecting with hardware functionalities, with simple backend structure at that.
• Stunning UI/UX: Count on hybrid apps for superior UI/UX across all operating systems and devices for maximum engagement and better user satisfaction.

Artificial Intelligence And Its Impact On Software Testing

Artificial Intelligence is changing the way traditional software tests are executed. From streamlining and automating tests to optimizing test results for more accurate results, AI can prove to be a boon for software testers worldwide.

Artificial intelligence has changed the way the software industry functions. Penetrating different areas of the industry, it has changed the game for several functions. Its potential impact on software testing is also being widely studied, with many expecting AI to provide huge savings on costs and resources related to software testing in the near future. And here are some ways the studies predict this will happen.

1.Predictive Analytics While Interpreting the User Behavior

AI can play a huge role in predictive and prescriptive analytics. AI can work on already generated test data from automation suites and analyze the test results. The result of these analysis can be used to identify and correct defects while predicting quality via providing appropriate process parameters and right courses of actions.

2.Automation While Gathering Data from Landing Page, HTML Pages

AI tools have become more advanced, to the extent that they are now capable of gathering insightful data from HTML, landing and related pages from websites. The tools make use of this data to learn about the application of test cases to different business usage scenarios. This, in turn, makes it easier for them to train ML automation models to generate a varying pattern of test cases for apps, execute them, mark variations as issues, validate the differences and then fix these issues.

3.Error-Less Data

The enormity of data associated with source analysis can make even the experts in the industry make mistakes from time to time. In the case of software testing, these mistakes can turn out to be disastrous for the product reputation and positioning if caught by consumers or potential stakeholders.

The benefits of artificial intelligence are manifold in these situations. AI tools can enable testing systems to learn about source analysis and apply this knowledge to testing scenarios. This, in turn, will not only enhance the accuracy of test cases but also reduce the risks associated with human errors, reduce the run time of tests and increase the possibility of detecting bugs early on.

4.Risk Reduction

Many factors go into understanding application risks. Some of these include the complexity of tests, application usage and so on. AI tools make it easier to identify the test cases that need to be executed for different test cycles. These tools collect data from previously executed tests for a specific application, thus making it easier to identify changes in code as and when they are made. Therefore, defects arising in the program can be easily identified via proper feedback early on in the developmental stage. These defects can be identified and rectified with proper solutions at the earliest to reduce the risks associated with an error-ridden application.

5.Fix Defects When it is Less Costly

Repetition of manual testing methods is not only time-consuming but an expensive resource for the company. This is where artificial intelligence enters the picture. Artificial intelligence tools allow for the automation of tests that need to be repeated continuously or periodically. The automation helps these tests to run several times automatically without human intervention. At the end of each test cycle, potential bugs are identified and the source code is changed to rectify them. The result of this is automated tests that take only a matter of hours (as compared to days in manual testing) and can save a lot of money in resources.

6.Allow AI to up-rise Your Business

The myriad benefits of AI tools on software testing can, in turn, prove to be beneficial for businesses. Rather than relying on traditional testing methodologies, testers can move to automated and precision-based testing procedures for more accurate results, which can prove to be invaluable for the growth of the business.

8 Universal Rules Of UI/UX Designing For Web Design Projects

A website or mobile application has to open quickly and perform efficiently to achieve SERPs and user loyalty. That’s where the User Interface (UI) and User Experience (UX) step in. UI is about the interaction between the user and the product while UX is the emotional outcome of the interaction. They go hand in hand and are equally important for Web Designing.

Here’re 8 universal UI and UX designing rules for all web developers to know and imbibe.

UX Design:

UX design usually precedes UI design. So, let’s start with the UX design strategies.

1.Keep it Responsive:

Websites and apps receive significant traffic via Smartphones. Your website needs to be responsive and mobile-friendly. These types of websites incorporate fluid and flexible layout that fits all screen sizes (from Smartphones and tabs to desktops) for an optimized browsing experience. Even Google algorithms prefer responsive and mobile-friendly websites for SERPs. However, ensure the responsive element doesn’t interfere with the website quality.

2.Ensure quick Loading Time:

Your website should load quickly. Slow load times not only frustrate users but also hamper interaction. Users prefer not to visit a website with a slow load time more than once. No one has the time and inclination for slow page loading time, after all. Such sites do not find favour with search engines either. Ensure going through WordPress resources for tips on speeding up your websites. Also, opt for a good web hosting server to keep your loading speeds up to the mark.

3.Make it Bulleted:

Users find it hard to deal with lengthy content, as it involves time and effort. Bullets, on the other hand, present all relevant information about your product or service in an easy to read format. The user can go through the information quickly and easily, and make buying decisions accordingly. The bullets can be paired with images to make the page look more attractive, and at the same time raise user engagement, product awareness and conversion rates.

4.Colour is Important:

Colour is perhaps the biggest visual element of your website. The right colour helps the website connect with the audience and send the right message across. Research suggests that different colours invoke different feelings. For example, bright yellow represents energy, and golden shades stand for antiquity, lavishness and wisdom. You are better off deciding colours for your website and the buttons based on the product you sell and your business’s bottom line.

UI Design:

Now that UX design essentials are out of the way, it’s time to focus on the UI design strategies.

1.Keep the page Importance-Based:

The thumb rule for a fine UI is to keep the page layout simple and importance-based. All key information needs to be presented in a way to attract user attention and ensure accessibility.

To this end, factor in the special relationship between all the page elements and put the UI elements thoughtfully. Avoid clutter and minimize visual elements. For readability sake, make the most of the headings, club similar elements collectively and add numbered items.

2.Stick to common UI Elements:

In web designing, form follows function. That calls for using common UI elements instead of unfamiliar, new ones to create your user interface. The user should be able to interact with the product quickly and easily, after all. Creativity can be compromised for the sake of functionality.

3.Be Good with Colour and Texture Usage:

The interface needs to be attractive and coherent, in line with the overall design scheme. So, be mindful of the hues, texture, contrast, and light when creating a user interface. All of them should be used strategically to draw user attention to the key information presented.

4.One Screen, One Action:

Visual clutter is detrimental for to website/app. It makes sense to endorse the one screen, one action principal. Herein, one screen should support one primary action only. Too many actions fitted into one screen confuse and distract the user, leading to low retention rates.
