You can participate and sit via ongoing conversations. During registration, every user gets muted automatically, but all users can unmute themselves when they start joining the discussions. You can join this app only by invitation. This makes Clubhouse a unique and exclusive social media application. Top Features to Add for Building a Voice Chat App like Clubhouse For now, Clubhouse is not available in the app stores, as it utilizes an invite-only model. New users get a TestFlight link and are greeted personally by the app maker who describes its work procedure. In case you want to build an app like Clubhouse, here are the main features to add: 1. Onboarding Once you are in Clubhouse, you need to enter your name and give an image. You can join any room you prefer directly from the beginning. Every new user is muted by default, but they can unmute themselves any time they want. 2. User Profiles User profiles contain a name, image, and short description. You can check who is now speaking and their accounts when you are in a room. Moreover, you can see the clubs where a user is a member and find who has invited the user to conversations and when. 3. Feed After opening your feed, you will find many discussions that are known as Rooms. Moreover, you can find every room’s name and all the members who are in the rooms. 4. Rooms Discussions happen in a room. You can see rooms, participate in their conversations and make your own rooms also. For this, you have to click the ‘Start a Room’ button on the screen’s bottom part. You can raise your hand in a room for interrupting the speaker or politely asking for speaking. You can declare that you are leaving or press the ‘Leave’ button quietly when you want to leave a room. Moreover, speakers can invite other users for speaking in the discussions in a room. 5. Search This is a helpful feature for every social media app that contains live content. In an app like Clubhouse, you can look for topics of discussion and people you wish to follow. 6. Clubs This feature is the same as Facebook groups. You can participate in clubs that you like and find people with similar interests easily. Moreover, these clubs let you view and add members and recommend chat topics. 7. Activity By clicking on the ‘Activity’ tab, you can see the interaction history of your account, incorporating the members who followed you.

Best Practices for Node.js Security

Leave a Comment / Uncategorized /

Like any other programming language or framework, Node.js is susceptible to every type of web app exposure. Although the basis of Node.js is secure, third-party packages may need more security standards to safeguard your web app. The study says that 14% of the NPM (Node Package Manager) ecosystem is impacted and 54% of the NPM ecosystem is about to be impacted indirectly. What Is NPM and What Is Its Relation with Security Issues? NPM or the Node.js Package Manager is globally one of the largest open-source package ecosystems. This rich ecosystem has caused a boost in the app’s functionality and developer productivity. Sometimes, Node.js codebases comprise hundreds or thousands of these packages. Maybe developers don’t know the direct and indirect dependencies of the packages and the security risks related to them. In 2018, NPM started concentrating on security, when they launched NPM audit. This new command performs a moment-in-time security assessment of the dependency tree of a project and creates the security report of an NPM audit. This report comprises the data regarding security exposures in the dependencies and offers NPM commands and suggestions for additional troubleshooting. Why Do Node.js Projects Have Security Issues? Open-source apps derive licensing and security risks from their open-source elements. Moreover, the security detecting tools like static and dynamic code assessment cannot identify open-source exposures efficiently. To detect open-source elements in Node.js, you must assess the NPM index files that explain the dependencies. Nevertheless, these index files don’t incorporate reused open-source elements. Sometimes, the open-source community reutilizes open-source projects to lower time-to-market, speed up development, and include functionality. As an outcome, both commercial and open-source developers can launch code snippets, functions, and techniques into files. Also, numerous Node.js web development projects incorporate licensing terms other than the real Node.js license. Top Node.js Security Risks and Solution Practices The security issues related to Node.js can expose you to vulnerabilities like the man in the middle, code injection, and advanced constant threats. Here is a list of Node.js security risks that may cause these vulnerabilities and their possible solution practices: 1. Restrict XSS Attacks by Validating User Inputs XSS or Cross-Site Scripting allows hackers for injecting vulnerable client-side scripts into website pages viewed by different users. Vulnerable client-side scripts can cause data breaches. Moreover, the hacker can use the JavaScript code. The reason for this is not validating input from users. Hence, whatever users put in the search field, if not discovered in the database, will be sent back to them in the same old form. Thereby, if a hacker puts JS code rather than the product name in the search bar, he can execute a similar JS code. Solution You can validate the user input. For preventing XSS attacks in Node.js, you can utilize output encoding methods or tools like the Jade engine with in-built encoding frameworks. Also, you can opt for, XSS-filters or Validatorjs for this. 2. Abstain from Data Leaks Don’t just rely on what you get from the frontend but also what you will convey to it. You can easily send all information for a specific object to the frontend and just filter what to display there. Nevertheless, it’s quite simple for a hacker to find the hidden data sent from the backend. Solution Only send the information that is needed. In case you just require first and last names, just retrieve those from the database. This may need you to do slightly more work, but this is absolutely worth it. 3. Utilize Security Linters You can scan vulnerability automatically. Moreover, it is possible for you to catch basic security exposures even while writing the code. Solution You can utilize linter plugins like eslint-plugin-security. This type of security linter will give you a notification whenever you utilize insecure code practices. 4. Implement Access Control on Each Request This thing is usually associated with how properly examined an app has been when it comes to user permissions to various URLs or areas of it. Thereby, in case you want to have limited areas on the app, such as admin dashboard, for instance, and normal users with no appropriate role can access it by any means, then you have access exposure. Solution The best way to get rid of this susceptibility is by manually testing app modules that need particular user permissions. Middlewares and access control rules are best executed on the server-side as they reduce the chances of manipulating access permissions from the client-side by JWT (JSON Web Token) authorization tokens or cookies. Log access controlling and API rate restricting must be set up. This is how admins get alert when there are important steps that should be taken for reducing the attack and repeated failures. 5. Secure Deserialization Insecure deserialization is a vulnerability that includes deserialization and application of buggy objects through remote code implementation or API calls. This kind of attack is known as CSRF (Cross-site Request Forgery) attack. This attack forces end-users to implement unwanted actions on valid web apps. The objects of CSRF attacks are modifications in app state requests, as the hacker cannot see the forged request reaction. Attackers can apply tricks on users via unusual actions by using social engineering methods, such as sending links through email or chat. CSRF can force state-modifying requests like transforming email ids and then fund transferring. CSRF can compromise the whole web app for admin users. Solution To reduce such hacks or attacks, you need to prevent CSRF. You can do this by using anti-forgery tokens in Node.js. These anti-CSRF tokens are utilized for preventing one-click attacks and checking and validating the authenticity of user requests. 6. Execute HTTP Response Headers Express is one of the most extensively used web app frameworks for Node.js. Nevertheless, Express was not created with security consideration. This is why older Express versions may have security risks. Solution You need to use maintained and updated versions for making sure the security of apps. In fact, you can avoid many less common attacks by adding extra security-related

We don’t know for how long the impacts of the COVID pandemic are here to stay. This is why many businesses are getting ready for this new normal period. Flexible and innovative businesses are growing stronger than others. Although industries like hospitality, retail, and travel need significant time to become normal, a few sectors like work-from-home solutions, gaming, video streaming, and eCommerce have become our instant saviors during this new normal era. And in this present situation, all types of mobile apps have become highly essential. Anything possible to do online is becoming digital. Simultaneously, mobile apps are not just becoming highly profitable and popular but also make a huge effect in helping people maintain social distancing and stay safe during this outbreak. So, honestly, we can’t imagine our lives without mobile apps in a post-COVID world too. Top 10 App Categories to Rule the Post COVID World Let’s explore the top 10 app categories that will become the most productive, effective, and accomplished businesses in the post-COVID scenario! 1. Healthcare Apps Healthcare apps have come as a savior in this sensitive time when everybody is concerned about health. Since we are not doing physical movements a lot these days, healthcare apps like fitness apps, meditation apps, medical care apps, and mental health applications are assisting people in keeping them healthy both physically and mentally. Online fitness programs instruct how to do basic yoga or meditation for keeping ourselves healthy even when staying home, the necessity of a balanced diet, and the types and perks of exercises. On-demand doctor’s applications offer instructions on medical sample tests, prompt consultation, digital prescriptions, and medicine delivery. Patients can consult the best doctors over medical applications for discussing their diseases and symptoms to get a better insight into their health and bear panic scenarios. A report by App Annie says that in March 2020, a combination of ten fitness apps incorporating Asana Rebel, 30 Day Fitness, and Nike Training Club has seen almost 5 million downloads within only one week. 2. Grocery Apps Nobody can survive without groceries. Hence grocery apps are one of the most important app categories on our list that has seen success during the pandemic. People are concerned about getting infected with the virus; hence, they are not ready to step out of their house for grocery shopping. Here, the grocery apps play their roles. These apps maintain the pace with the rise in demand and feed people most securely. The most famous grocery applications like H-E-B, Target, Shipt, Instacart, and Walmart encountered a massive number of downloads during this worldwide crisis. Grocery applications have gone through a great transformation from hardly being an option to becoming the ultimate need during the pandemic. 3. FinTech Apps FinTech or finance is another app category that is experiencing a huge increase in demand. The uncertainty in the economy along with the failure to visit banks has caused many people to use mobile apps for handling their money. A report from App Annie says that in Q1 2020, the whole time spent in finance applications increased by almost 55%. The increase was sharper at 90% and 85% respectively in South Korea and Japan. In April 2020, a FinTech app named Robinhood ranked #1 on app stores in its category and increased by 260%. From fundamental activities like paying bills, using bank accounts, and fund transferring, to things like stock monitoring, trading, investing, and personal finance management, all have become possible due to mobile apps. Customers search for user-friendly, trustworthy, and secure apps, to solve all monetary issues. From the first week of January to the end of March, the overall time spent in stock market applications increased by 80%. The market uncertainty and poor economy are reasons behind this. As a new trend, customers are currently using their banking apps daily. 4. Dating Apps Dating apps have seen a massive surge during this global lockdown period. There was only a 5.3% increase in using these apps in 2019. But during the Coronavirus outbreak, we have seen a huge increase in the download of apps like Hinge, Bumble, and Tinder as all face-to-face meet-ups have been prohibited. In 2019, it was already forecasted that more individuals would be meeting their partners virtually by 2035. On 29th March 2020, Tinder users worldwide swiped through 3 billion probable matches. And this was a record-breaking incident. This trend is going to stay for a long as real-life dates can be very costly. Hence, meeting a person through a dating app will be less expensive and more effective for working out a relationship. 5. Entertainment Apps Engaging entertainment apps help people reduce their boredom. During this pandemic, entertainment apps like Scrabble GO, IMDb, Snapchat, Google Play Music, Spotify, YouTube, HBO Now, Amazon Prime, Netflix, etc. have encountered a great surge. Kids are captivated in gaming applications for engaging themselves and get quite fun during this critical scenario. Adults are also engaged in news applications to get updates on current happenings globally. News apps like Google News, BBC News, CNN, etc. have become more popular as people are curious and concerned about the most recent happenings worldwide. They want to learn about the precautionary measures more to understand how the whole world is dealing with this crisis. Moreover, they want to know what healthcare and government entities are asking them to do. 6. e-Learning Apps Lockdown not only prompted students to use online resources but also turned many people to try and excel in new skills for passing the time. For instance, famous online language apps like Duolingo experienced a 148% spike in registration during March 2020 in the US. In late March, Udemy encountered a 425% increase in enrolments. Maybe the sudden energy for mastering skills will just remain until people go back to their normal life, but the e-learning organizations may continue to experience success due to the low cost and ease they are offering people for helping them pursue their new hobbies from home.

How to Develop a GPS Navigation App like Waze?

Leave a Comment / Uncategorized /

Navigation applications are getting highly popular these days. The number of location-based service users is predicted to increase in the future. Hence, if you are also planning for creating a GPS navigation app, you are on the right track. According to the report by BIS Research Agency, the market of the navigation app is developing continuously, with an expectation of $34.56 billion income by 2021. Hence, having a navigation app can bring lots of profit to your business. Waze and Google Maps are the two most famous apps for both Android and iOS in this sector. They provide turn-by-turn directions, lots of real-time data, and other features that make them more appealing. The Concept of Waze App Waze is a high-end GPS navigation app that has some amusing and useful features. This is the 2nd top-rated mobile app among users, beaten by Google Maps only. It allows users to get real-time traffic updates, use live maps, and other road information. Waze was the 2nd most popular map app in the USA in April 2018. It had 130 million monthly active users in 2020. The yearly revenue of Waze is estimated at $37.7 million. What is the reason behind Waze’s success? Take a look at how it works to know more! How Does Waze Work? Global users use Waze for enhancing one another’s routes by sharing real-time data regarding road repairs and traffic conditions. Waze helps you inform others regarding police traps, accidents, weather conditions, blocked roads, and so forth. This app instantly assesses this data to make sure that others can explore the ultimate routes. Waze is the official navigation app for many taxi booking apps like Lyft. Waze is different from conventional GPS navigation app as it is community-driven, collecting traffic data and complementary map data from its users. Whenever the app is running, it collects data. It must have exact data from every closer road for offering the shortest route. At the time of your driving, the app will compare information for every possible route and provide the ultimate route as per your choice. You require an active internet connection for loading routes as Waze does not work offline. To keep the map updated and power real-time traffic data, you need an internet connection. In-app location-based advertising is Waze’s own ad product. It’s a location-guided ad platform for businesses that need to attract nearby drivers’ attention. While driving, you can see ads for nearby eateries, stores, and other areas. The most interesting fact is that Waze assesses not just your area but also your destination to provide the most appropriate advertisements. This map app has made a system where any local business can claim locations on its maps while conveying local ads and targeted messages to people who are driving nearby and seeking a location. What are the Key Features of a GPS Navigation App like Waze? Before developing a Waze-like GPS navigation app, take a look at the major features to implement: 1. Authorization It’s an important part of an app like Waze. After registration, users get personal accounts where they can put reviews and notes and communicate with others. You can either log in through your email and password or by connecting a social account like Facebook. 2. Real-Time Updates Having high-quality satellite pictures in a navigation app is good enough, but Waze does something more. Real-time updates from other users make a highly fruitful user experience. Furthermore, you can upload images and add notes to offer other completely precise data. 3. In-App Messages In case you want to pep up your Waze-like navigation app, think about displaying user messages more attractively. Do you want to deliver them as push notifications or send them to a chat? This can be done for navigation apps when a user enters a particular region or location. 4. Voice Navigation Drivers should not be distracted by a map. Turn-by-turn navigation is a necessitous feature and a mobile GPS navigation app is nothing without it. Voice navigation helps drivers hear directions like where to turn or which route to use, traffic alerts, and notifications in case they have a better route. In case voice navigation distracts you, you can switch it off. 5. Social Networks Integration You must integrate your app with social platforms for the reason of authentication and offering social features. Moreover, social network integration improves user experience and reduces security risks around authentication because most possible problems and vulnerabilities are already maintained. Also, you will not be forcing users for making another account, but utilize their current accounts for seamless login. 6. Rerouting Your GPS navigation app requires rerouting drivers fast in case they stumble upon a road accident or make a wrong turn that stops them from following the basic directions. Drivers don’t need to wait for long for your app to reanalyze the route; they get precise directions directly. 7. Geolocation & Navigation The map creates the basics of a navigation app. It utilizes the GPS system for deciding user location, locating objects, and showing the route. To reduce mistakes, you can incorporate the Cell ID functionality in your app, as it depends on information coming from mobile operators. In case your team combines Cell ID and GPS, the Geolocation services of the app will be accurate. 8. Payment Services A GPS navigation app might incorporate in-app purchases as a monetization method. In case your app becomes popular among drivers and people who offer complementary services, there is a possibility of partnership. 9. Carpool Service A Waze-like Carpool app enables drivers to get free gas. In case any user is going in the same direction, you can see him on your screen. Drivers and riders share the gas expense for the trip. Ride charges are fixed beforehand at a rate recommended by the Waze-like app. The app charges the credit cards of bank accounts of users automatically. 10. Google Calendar Synchronization The users of the Waze-like app can sync the app with Google Calendar for

Leave a Comment / Uncategorized /

Every developer should keep all updates of the latest news and trends related to their main technology. The capacity of continuous learning and getting acquainted with the ever-changing environment is the main feature of a developer. In case JavaScript is your main technology, you are at the right place. ReactJS has become very popular after its introduction. Many industry leaders moved to this technology after its launch. Nevertheless, developers find it tough to recognize the right React libraries for developing their apps. In this blog, you will get to know about the top React libraries and frameworks. What is ReactJS? ReactJS is an open-source JavaScript library that helps developers create a top user interface for both mobile and web applications. There are many benefits of ReactJS and reasons to choose it for your project. It feasibly integrates with other JS libraries and frameworks and comprises standalone, small bits of code, named Components. You can use these components to create some awesome apps. 20 Essential React Libraries and Frameworks Before starting your next React project, take a look at the top 20 React libraries and frameworks that can help you build some apps with amazing UI. 1. Redux Redux is a state management solution for JavaScript apps. Generally, it is used in integration with React, but it functions with other React-like frameworks also. For Redux, it has become possible to connect all components straight to the whole state and thereby, reduces the requirement for using call-backs or props. 2. Create React App Create React App is a CLI tool that does not need any developing configuration. It promotes the creation of your own standard and helps you start the app developing procedure seamlessly. You require just a build dependency, and thereby, there is no complicacy. More favorable for simple web applications, the Create React App has under layers of ESLint, Webpack Babel, etc. 3. Rebass This essential components library is developed for building a stable UI with user-defined scales and design constraints. Using a footprint of just 4KB, Rebass is all about quick design and development. Rebass aims to be helpful, minimal, expandable, unopinionated, and themeable through its compatibility with Theme UI and best-in-class assistance for theming. 4. React Admin React Admin is useful to create B2B admin apps on top of REST/GraphQL APIs and can be customized by design. It is created with several popular projects alongside React: Redux, React Router, React Final Form, and Material UI. 5. Ant Design Ant design is a consolidated building framework of Webpack, NPM, DVA, Dora, and Babel. This component library is broad and it has an exceptional client base. Moreover, it enables you to place your UI components, which, as a result, gives a seamless user experience. This useful React library offers ES6 support and allows hassle-free integration. 6. Grommet Grommet, a component library is made for mobile-first, accessible, and responsive web projects. It enables screen reader tags, keyboard navigation, and more, and includes atomic design strategies. Moreover, it has many svg icons. Several large organizations utilized Grommet for designing their web applications, incorporating Twilio, Samsung, HP, Boeing, Uber, and Netflix. 7. Material UI Google made this set of components that execute their popular Material Design. Material UI is the most famous UI package of all React libraries, having more than 67000 stars on Github. It is user-friendly, light, attractive, and simple. Developers have been using this for some years, but due to continuous updates, it has gathered more popularity. 8. React Spinner Unlike other React Libraries, React Spinner has something different to provide. It comprises loading spinners depending on Halogen. It’s an entertainment factor that keeps visitors involved during the page loading so they don’t feel the urgency for leaving the page simultaneously making a better user experience. React Spinner has more than 20 React loaders to provide to all users. 9. React Bootstrap React Bootstrap is a UI kit that retains its Bootstrap origin. To help you get more control over every component’s form and function, it replaces the JavaScript of Bootstrap with React. Every component is made to be essential for front-end framework development and easily available. As React Bootstrap does not differ much from its Bootstrap cores, developers can select from the thousands of readily accessible Bootstrap themes. 10. Semantic UI React Semantic UI React is the official plugin for Semantic UI. It is free from jQuery and contains shorthand props, a declarative API, augmentation, an auto-controlled state, sub-components, and so forth. This React Library features a list of more than 50 components, incorporating pagination, transitions, progress bars, segments, and so forth. Semantic UI offers the themes as CSS Stylesheets whereas Semantic UI React offers the components. 11. Blueprint In Blueprint, the React components are mainly for utilization on desktop apps. These components are specifically favorable for developing data-dense and complex interfaces. You can choose bits of code for creating and showcasing icons from the component library, choosing time zones, communicating with times and dates, and more. 12. React DnD DnD shows the Drag-and-Drop interface with React. It provides gesture and grabbing-based user interaction for choosing visual objects and then dragging them to a suitable location throughout the device screen. React DnD is made using HTML5 drag and drop API and it internally utilizes Redux. It offers the crucial scopes to build Trello-like complex drag and drop interfaces without impacting data constancy and transfer in the app state. In maximum cases, this API is the mainly suitable library for building drop events. 13. Styled Components Styled Components is a CSS tool that helps you streamline your React project. This library helps you create reusable, small components important for the appearance of your application. With conventional CSS, you may face the issue of unusually overwriting selectors utilized in the website’s other places. However, due to Styled Components, developers can abstain from this problem by utilizing CSS syntax straight inside all components. 14. React Fabric Also named as Office UI Fabric, React Fabric is popular for the native application of

The Benefits of Using White Space in UI Design

Leave a Comment / Uncategorized /

Visual and graphic design has developed a lot over the past years and presently known as UI design. As data sharing, communication, business, and entertainment all are happening online now and everybody wants to retain all users by offering the best experience, UI design has become a field of massive importance. One essential feature of visual or UI design that has remained the same over the last years is whitespace’s importance. This blog gives a brief overview of white space and how it can highly impact the efficiency of the UI design. Read on to learn more! What is White Space in Design? White or negative space is just an unmarked space in the visual design. We can find whitespace between the lines of paragraphs, layouts, among different UI components, paragraphs, and more. Compared to its name, whitespace does not only apply to the white color. It can be any texture, color, background image, or pattern, as it refers to the design’s background. Why Does White Space Matter in UI Design? As white space is a crucial aspect of UI design, it can change the design and offer several benefits to your website if used correctly and properly. Being a designer, you must create and deliver layouts that are smooth enough and make people engaged in reading. One of the perks is white aesthetics; others grow around tangible effects on the webpage’s efficiency. The prime difference between an average and a good product can be seen through its design. Being a designer, you should not only fulfill your clients’ needs but also consider the average users while making a product. Whitespace not just enhances UI but also the UX of the webpage. Let’s take a look at some factors that depict why white space is crucial for UI/UX design! 1. Adds Emphasis What happens if you use whitespace for separating a design component? Our brains use to give stress and importance to design components surrounded by whitespace. After all, the negative space is offering visual clues regarding where you must be looking, giving sufficient buffer space around a component so your brain can process it ASAP. For this reason, sometimes, whitespace surroundsthe crucial design components like logos so they are clearly visible and emphasized. Space can keep the logos separate from other components so the viewers get attracted by your branding and don’t get confused with other pictures. 2. Enhanced Comprehension The use of whitespace smoothly makes the content in design scannable easily and enhances legibility significantly. According to research, the appropriate use of whitespace between lines of paragraphs and its right and left margins can maximize comprehension up to 20%. The small spaces that we find between paragraphs, lines, or menu items are also known as Micro Whitespaces. 3. Guides Your Users’ Eyes Using whitespace design can help you guide your users’ eyes. Do this by streamlining the content of your page into less than 15 points on that page. Then fix the order of priority for those 15 points. For instance, the first point might be the logo, the second one might be the navigation bar, the third one might be a hero image, the fourth one a text paragraph, and more. While placing this content, you must decide on where the macro whitespace will be, i.e., where you will put every group of elements or piece of content on the screen. Macro whitespace surrounds every component or group of components. On the other hand, this space surrounds different components in one group or the spacing between letters, lines, and paragraphs in a text. 4. Maximized Interaction Rate According to studies, an internet user’s average attention period is 6 seconds. Efficient use of whitespace helps the UI design get the message via users fast and maximize the possibility of interaction by featuring the Call to Actions. So, designers must create communication lines between users and the design and whitespace can help much in it. Have you checked the home page of Google Search Engine? The utilization of whitespace is quite apparent and communicates the page’s search purpose clearly. 5. Gestalt Principle of Proximity The Gestalt Principle of Proximity keeps up that users relate closely associated components to have the same features. For implementing this principle properly, you will have to ensure that your group-related components close together. Take Form Design as an instance. For instance, you might need to gather personal details like name and address in a single group, individualized by a little more space and followed by another group of fields under the details of a credit card. 6. Entails Luxury and Sophistication Whitespace can become the core design element if it is used for making a specific appearance or mood. We relate a huge amount of whitespace to sophistication and luxury, so utilizing it efficiently may be the method of adding these associations to your design. Lots of graphic components make the entire design cheap. Instead, try to boost the design by adding more imagery. Let the whitespace work so you can just concentrate on making a better appearance of your graphic elements. 7. Puts Imagination into Effect While people see whitespace in a UI design, it enables their imaginations to travel free, which yields a more powerful emotional response. Humans’ brains have an elemental requirement for assessing things, which makes a type of narrative between what you see and how you can process it. What our minds mark onto the whitespace does not really matter; thinking about it involved our mind is important. In case you are involved, you are personally investing in the design. Investing in a design personally makes it more possible to make a great first impression. 8. Showcases the Visual Hierarchy Using whitespace helps you showcase the visual hierarchy between components on your page. Ponder increasing or reducing attributes like margin and padding for putting more stress on specific elements. Ensure to place essential components like CTAs in the place where they especially look different. 9. Focuses on Important

What Are the Different Types of Cloud Computing?

Leave a Comment / Uncategorized /

The trend of cloud computing is constant in the IT industry. Generally, the term is used by IT businesses, experts, and companies. Nevertheless, the term itself incorporates various types of cloud computing. Cloud computing is advantageous for companies. It provides flexibility, lowers IT expenses, increases efficiency, enhances data sharing, and scalability. Moreover, you should know that there are many models and types of cloud computing. Since there is no model perfect for all businesses, you need to recognize the most suitable model by learning about the different cloud computing types. Selecting the best cloud computing type or model for your company caters to the usability, your company’s size, cost-effectiveness, advantages, requirements, and the variances provided by every kind of cloud computing service. Hence, you should understand the available models or types and decide the deployment that best meets your company’s requirements. What is Cloud Computing? Cloud computing is all about offering computer resources on-demand through a PAYG (Pay As You Go) model. These resources incorporate databases, virtual devices, data storage, serverless infrastructure, and so forth. According to report, the cloud computing market size is expected to grow from USD 371.4 billion in 2020 to USD 832.1 billion by 2025 globally. Types of Cloud Computing Cloud computing models differ depending on how data communications and sharing occur, how data is stored, and how cloud-based apps run. Although there are many classifications, 3 main types of cloud computing are found: Private, Public, and Hybrid. We will explore each of them individually, depicting the pros and cons of every type. 1. Private Cloud According to its name, the private cloud service is intended for single-use. Generally, its resources are found on-premises or a third-party vendor operates it at an offsite area. Third-party providers detach the computer resources through a private, secure network that cannot be shared with other clients. According to report by RightScale, The average business runs 41% of workloads in private cloud. The private cloud solution is the single tenancy model that is situated within the company’s network and has private exposure only. The company handles it internally on its own and offers all hardware elements. A private cloud is usually a highly expensive model. Advantages of Private Cloud Supports legacy apps. Private access makes sure a safe and dedicated solution. Extreme level of flexibility enables changes in IT and business requirements without compromising performance and security. Government and regulatory compliance are simpler, as the private cloud model features custom-made security. High-efficiency levels and SLA (Service Level Agreement) improve functionality. Disadvantages of Private Cloud Needs extremely skilled experts. It’s a costly solution. Mobile users get restricted access. Not relevant for short-term use cases. Infrastructure scalability may be limited in case the cloud data center is restricted to on-premise computing resources. Suitability Meets large data center requirements of large enterprises. Relevant for companies that can invest in high-end technologies. Maintains powerful security measures and controls over IT workloads and the fundamental infrastructure. Suitable for extremely regulated industries. 2. Public Cloud Public Cloud is the most common type of cloud computing model, gives the public access to the resources through the web. This can be paid (through a subscription) or free service. The public cloud’s computing functionality of every provider is not the same. Public cloud solutions provide scalability and elasticity cost-effectively. As per Statista, the global public cloud computing market continues to grow and is expected to reach an estimated $397 billion in 2022. Public Cloud is a multi-tenancy model with complete exposure found anywhere on the web within the boundaries of the service provider. The service provider externally deals with it and fulfills all hardware elements. Usually, a public cloud model’s cost is moderate. Advantages of Public Cloud Anybody can utilize the services online. It is highly scalable. Agile cost structure enables companies to concentrate on other kinds of investments. PAYG pricing model helps you determine the cost level. High availability helps you fulfill extra resource needs easily. Usage and setup require less technical knowledge. Public cloud providers have in-built apps and services preferred for IT and business operations. Predictable computing requirements lower possible downtime. Disadvantages of Public Cloud Restricted infrastructure control. The ownership cost cannot be predicted and might increase for large-scale users. Can’t meet every security need. The service provider may limit the use of their software and hardware. Can’t totally support the industry standards, legal needs, needs of government policies, etc. Suitability Usable in testing and development ambiances. Suitable for companies with predictable computing requirements. Relevant in case resource needs vary frequently. Suitable if cloud services and apps of public clouds can meet business requirements. 3. Hybrid Cloud The Hybrid Cloud is a combination of private and public cloud solutions with an integrated infrastructure where the privatization of sensitive apps happens, but common services’ hosting happens in the public cloud. Users can utilize the app and data workloads located in both the public and private clouds. This is a mix of single and multiple tenancy models with both public and private exposure and is situated inside the service provider’s location and the company’s network. Both the service provider and the company deal with the hybrid cloud and each of them offers some hardware elements. A hybrid cloud model’s cost is variable, based on which portion is public and which one is private. As per research, 45% of enterprises see hybrid cloud as their top priority and it is the weapon of choice for them. Advantages of Hybrid Cloud The hybrid cloud is extremely authentic as it offers shared services across multiple cloud solutions. Government and regulatory compliance, and legacy needs are simpler to fulfill in comparison with a completely public cloud. Offers more scalability and flexibility than completely private cloud apps without disturbing security. You can utilize both cloud-native and legacy apps. Costs are lower than a completely private cloud solution. Disadvantages of Hybrid Cloud Needs high-end tech expertise for establishing, handling, and maintaining the solution. Can be costly, particularly compared to the public cloud. Infrastructure can

Leave a Comment / Uncategorized /

Google announced Flutter 2.2 (a latest version of their cross-platform app development framework) in Google I/O event. And, it has exciting improvements like Android deferred components, iOS performance improvements, Null safety by default, improvements to Desktop and Dev tools, and many more. There is lot to know about the latest updates of Flutter. So, let’s take a deep look at Flutter 2.2 with all the newly added features. Dart 2.13 Flutter 2.2 comes up with a range of improvements and Dart 2.13. It includes the second most requested feature type aliases, Dart FFI, update on the null safety feature, etc. Type Alias You can create a new name for any existing type and then this name can be used instead of an existing type. Before Dart 2.13 users can create a type alias for the function now it’s extended to the variable type. Example: The best thing about the type alias is that it passes the type equality test as well. And it’s legal to call the constructor on a type alias that names a class. Example: The advantage of using a type alias is you can make it easier to read your code to the others. Dart FFI (Foreign Function Interface) FFI is a mechanism for calling C code. And FFI has a new feature in which user can wrap the inline array in dart directly. Example: Instead of Another improvement in FFI is now it supports packed structs. This helps omitting padding to lower overall memory consumption. Example: Dart 2.13 includes other changes as well related to performance improvement and reduce space occupied by the program. Null Safety Update Now if you create a project using Flutter 2.2, it will generate a project with null safety by default. Most of the plugins are mitigated to the null safety it is safe to migrate the Flutter app to sound null safety. Flutter Desktop Updates Custom Text Actions Flutter extended its support to a number of platforms with different input types (touch, Mouse+Keyboard). In this release, users can fully customize the keystrokes associated with the text actions. This feature open-up endless possibilities for the Flutter app developers. For example, it is allowing users to send a message with the ENTER Key while still allowing a new line to be inserted via Ctrl + ENTER. Automatic Scrolling Behaviour In this release, whenever content exceeds the screen height scrollbar will be added automatically. Before this release on Android and iOS, there is no scrollbar added automatically developer has to add it manually. With this update flutter introduced customization for the scrollbar UI. Using ScrollBarTheme you can change it app-wide and for specific screen ScrollBehavior. Mouse Cursor Over Text Spans As we know, TextSpan is not a widget and we can change the mouse cursor when hovering over a clickable widget except TextSpan. Now it’s a past with Flutter 2.2 when you are using TestSpan with GestureDetector user will get the corresponding mouse cursor. It also supports onEnter and onExit events. Payments and Monetization Flutter 2.2 includes a new plugin to add Google Pay on Android and iOS and new ad format via google mobile Ads SDK. With the official Pay plugin from the Google dev team becomes easy to implement the payment process on both platforms. It’s easier than before to monetize the app through in-app purchases, payments, and Ads. Supports Deferred Component for Android The deferred components are not new for the Android developer but now it’s officially introduced in Flutter 2.2. But the sad thing is that it’s limited to only Android for now it’s not supported for iOS yet. For those who don’t know, what is deferred component? The deferred component is the piece of code that can be downloaded OnDemand run time. For more detail you can visit the official page for the deferred components. The Resolved First-jank Issue for iOS If you have noticed when you run the app for the first time it seems to be janky. After a subsequent start, it feels normal. It’s because of shader compilation jank. In simple term; the shader is a piece of code which needs to be compiled on the device. To resolve this issue, you can visit this page it has all the details. It’s not fully resolved but the Dev team tried to resolve it to some extent. Windows UWP Apps Universal Windows Platform Apps now moved to alpha in the dev channel. UWP apps can be run on a wide range of devices where standard windows apps don’t run including Xbox. To enable UWP support in the project you need to switch to the Dev channel and have to set up the pre-requisites. For more setup detail you can visit its official website. Dev Tools The development tool is important as the end product which helps developers to build more memory efficient and error-free apps and the Flutter team knows it very well. In the context of that in this release, they have introduced two new memory tracking improvements and a whole new tab for the ‘provider’ plugin. Memory tracking improvement gives the developer the ability to track down where objects as allocated. It’s really helpful to find a memory leak in code. And another charming feature in the dev tool is a developer can inject custom messages into the memory timeline. Using this feature developer can check that he is cleaning up things properly or not. Sometimes you need to track down in package Dev tools got you covered. In the dev tool, a new extra tab added which is dedicated to the provider package. You will automatically see a new provider tab whenever using the provider package with the latest flutter version. Flutter Web Updates With this release flutter introduced lots of improvements for the web platform. One of the main improvements is they have fixed double-downloading of main.dart.js prior to this version the service worker downloads the update, and to see those changes the user has to refresh the page couple of

MEAN Stack Vs MERN Stack: A Comparison Between the Two Tech Stacks

Leave a Comment / Uncategorized /

No matter whether you are an IT expert in a company or an entrepreneur who has plans for launching web and mobile apps, the selection of the right technology stack is slightly difficult. And in this regard, you might have come across the comparison between the MEAN stack and MERN stack. The digital world is transforming every moment and we are experiencing a lot of tech advancements and new market demands daily. Hence, in this digital era, having an app or website is not the single way of growing your business. You must be smart enough in selecting the right tech stack for your project. Choosing the right technology stack for your business will impact your future development also. So, should you employ either MEAN stack or MERN stack? Which one will work greater for your business? In terms of getting answers to these questions, you must learn the basics like differences, similarities, and perks of these two. So, let’s begin with introducing both the MEAN stack and MERN stack first! What is MEAN Stack? This is full-stack and extremely popular technology stack. The term MEAN stands for MongoDB, Express.js, Angular, and Node.js respectively. For developing mobile and web apps, programmers use this stack. MEAN is an open-source, JavaScript-based technology stack. Since this stack provides essential plugins and tools, it is helpful for developers for building mobile and web apps fast. Benefits of Selecting MEAN Stack It is less costly. Every technology in the MEAN stack is open-source that lowers the development cost. MEAN stack makes Isomorphic coding possible. With its help, you can easily move the code to another framework that is written in a particular framework. Angular is a JavaScript-based open-source framework that provides reusability, maintenance, testability, and high speed. It is cloud-compatible and open-source. MongoDB helps in sending cloud functions within the app by reducing the circle space cost. Easy switching between server-side and client-side is possible with MEAN stack. This is beneficial for developers for easy and quick development with JavaScript. Developers must know JavaScript to handle the whole project with it. What is MERN Stack? This is another open-source tech stack that can also be categorized as full-stack. The term MERN stands for MongoDB, Express.js, ReactJS, and Node.js. This helps build hybrid mobile apps and web apps with it. The MERN stack is created to provide a smoother development process. It is a group of JavaScript-based frameworks, databases, and runtime environments. This tech stack provides an end-to-end framework to developers, and it is becoming popular faster. Benefits of Selecting MERN Stack Set up with amazing community support. In-built wide suite of testing tools. React library gives you access to high-end tools for building apps. Developers are free to use the library for designing their web apps. It supports model view controller (MVC) architecture for a smooth development process. Developers must be experts in JavaScript and JSON to employ this JavaScript stack. This tech stack covers both the development cycles from front-end to back-end with JavaScript. Developers can use codes written on React on both browsers and servers. This JS stack gives the flexibility of making pages on the server when required. MEAN or MERN: Which One Is High on Demand? You need to select a popular tech stack and your scopes of finding expert developers increase if you select the right stack as more developers would possibly know it. The popularity of Angular vs. React inspires MEAN vs. MERN stacks’ popularity, respectively. Although Angular has been very famous, now React is beating it presently. According to the 2020 HackerRank Developer Skills Report, 32.3% of developers wanted to learn the React in 2020, which made it very famous. A similar number for Angular decreased to 27.6%, which signifies that React is becoming more famous than Angular. The 2019 StackOverflow Developer Survey report also supports the same observation that the React is becoming popular. According to this report, almost 74.5% of developers like to develop using React. The same number for Angular is 57.6%. Both React and Angular are extremely on demand. Nevertheless, with time, you will find it simpler to employ React developers than Angular developers. MEAN Stack vs. MERN Stack: A Detailed Comparison The main difference between MEAN stack and MERN stack is the use of Angular and React, respectively. Both the stacks have some positive and negative characteristics. Aside from the advantages provided by both the stacks, some factors make the variation between them. Let’s move directly to the point to conclude! 1. Learning Curve Node.js, MongoDB, and Express.js are very popular and they contain great documentation. There is no apparent difference in the learning curve of MEAN and MERN. Nevertheless, your learning curve will change between React and Angular. The Angular framework utilizes templates and Typescript. You may discover a steeper learning curve with Angular, while the React does not contain much learning curve. 2. Profitability Since Node.js, Express.js, and MongoDB are common to both MERN and MEAN stacks, the profitability comparison between these two would reveal between React and Angular. Angular, being a complete framework, provides better profitability. Generally, you would use third-party libraries associated with React that provide lower designer productivity. Angular features a CLI (Command Line Interface) and this enhances the productivity of designers. And when you redesign your code, you will discover that the Angular CLI makes it easier. Due to the existence of outsider libraries, updating your React code is a more added exertion. 3. Data Flow In the case of Angular, the data flow is bidirectional, i.e. if you alter the UI, then it transforms the model state automatically. In the case of React, the data flow is unidirectional. So, if you use React, you can alter the UI only after transforming the model state. React’s unidirectional data binding gives a better data overview, which helps handle large projects. And this makes the MERN stack more favorable for handling large projects. In case you are working on a small project, the bidirectional data binding provided by
