An API is a set of rules that determine how apps or devices communicate and connect with each other. Tech giants like Facebook, GitHub, and Netflix are the leaders of this show as they are hiring developers with open arms to exploit their data by using APIs. Since APIs help developers communicate with the data, they become more comfortable and easier for developers. However, REST APIs must be well-designed; else, they can create many difficulties for developers rather than enhancing the user experience. This is why REST API best practices must be followed when it comes to catering to your clients with the most efficiency. What is REST API? REST API (also known as RESTful API) is an application programming interface. Usually, HTTPS communication protocol accesses the Restful app programming interface. Basic Features of REST API Before delving into the best practices for the RESTful API design, let’s first learn the key traits of REST API: 1. Easy to View and Read Developers can easily and comfortably work with a precisely designed API as it is easy to read. They can remember its related functions and resources while dealing with it constantly. 2. Hard to Misuse You can somewhat reduce the possibilities of writing wrong code if you execute and integrate your API with a sharp and clean design. Also, it gives crucial feedback without commanding tough instructions on the end customer. 3. Outright and to the Point A comprehensive API helps developers make potential apps against the data hazard revealed by you. Hence, many API developers don’t hurry to complete the whole project simultaneously but rather create on the existing APIs. 10 Best Practices to Follow for REST API Development If you want to make your API user’s life simple and precise, you must follow some of the best REST API design and development practices. Here are some proven methods to follow while designing and developing REST APIs: 1. Clear and Concise Documentation You must have complete and clear documentation. Oftentimes, documentation is produced automatically depending on the API definition. Otherwise, you will have to ensure that the documentation can be understood easily by people with less or no experience. You need complete documentation so it can help users learn security, authentication, and error management. Moreover, it provides engaging tutorials, guides, and easy-to-use resources. Comprehensive documentation makes it simpler for users to use your API. 2. Utilizing JSON as a Data Format JSON is the most commonly utilized data format, although you can send data in other formats like CSV, XML, and HTML. JSON syntax can make data easy to read for humans. It is easy to use and offers quick and easy data assessment and execution. Moreover, it contains an extensive array of supported browser compatibility. 3. API Versioning This practice enables developers to make changes in particular actions or the data structure. You may deal with more than one API version if your project increases with time and in size. But the benefit is that this enables developers to create more enhancements and changes in their service alongside holding a part of API users that are slow in accepting new changes or not ready to change. We find mixed feedback on whether we should include an API version in the URL or a header. Academically, it should be placed in the header. But, the version must be present in the REST API URL. This makes sure the search of the browser across different versions, offering a seamless and easy experience of development. An API is usually unstable and variable as well. Although you cannot avoid the change, you should check the ways of dealing with the change. Scheduling a well-documented and declared depreciation every month is a great practice for plenty of APIs. 4. Error Management Errors should be smartly managed to reduce confusion for every API user. This returns the HTTP response codes that explain the nature of the mistake that occurred. The API maintainers get ample data from it to assess the source and reason behind the issue. If you want to keep your system error-free, just leave them unmanaged. Hence, the API customer needs to deal with errors. Here are some basic error HTTP status codes: 404 Not Found – This means that there are no resources. 403 Forbidden – This implies that an improper user has no permission to use a resource even if he/she gets verified. 401 Unauthorized – This means that the user is not authorized to employ a resource. Generally, it goes back if a user does not get verified. 400 Bad Requests – This implies that the client-side input has been unsuccessful in documentation or validation. 503 Service Unavailable – This marks that something unnecessary and unexpected action occurred on the server-side; for example, system failure, part failure, server overload, etc. 502 Bad Gateway – This denotes a null or invalid response from a crucial server. 500 Internal Server Error – It’s a basic server error. 5. Enhancing API Security Using present security frameworks like TLS and SSL is another great practice for creating APIs. SSL certificates can create a secure connection by offering a private and public key. Without this encrypted connection, you cannot get an assurance that you are safeguarding sensitive data like financial or medical info properly. TLS is SSL’s most modern version that provides improved security and protection. Regular testing is one of the essential API security best practices. You can use these 2 necessary tests: Penetrating Testing – This test decides the exposure of APIs to a real cyber attack. The tester looks for susceptibilities that might be misused by the hackers. Fuzz Testing – This test is useful for checking how APIs respond to the unnecessary or invalid input for finding errors or flaws in the code. Ultimately, rate limiting can easily prevent DoS (Denial of Service) attacks where excessive requests ruin an API’s basic functionality. Restricting the number of requests per user for some time can safeguard your API from such

Like eCommerce, online marketplaces have taken people’s shopping experiences to a greater level. Marketplace giants like Amazon, eBay have initiated some. With more than 300 million active users worldwide, this Amazon is leading the marketplace these days. Almost 197 million people visit Amazon website and app every month and purchase products from it. With net revenue amounted to 386.06 billion USD in 2020, Amazon has not only become a ruling tech biggie but also encouraged entrepreneurs and startup firms for investing in its eCommerce mobile app. However, developing a multi-vendor marketplace app like Amazon can be tricky for you. You need to add the right features and implement monetization strategies. So, how will you go about developing a marketplace app? Without further discussion, let’s have a look at the details! What Are Marketplace Apps? An online marketplace is a platform for both sellers and buyers to join together in massive numbers. It works as the intermediary between different groups, offers a feasible environment and required guarantees. A marketplace app is slightly different from an online store. A marketplace app is created for easy and smooth shopping on a device like a mobile or a tablet. These apps are different as per the type of products they offer, the size, and the way they advertise themselves. Marketplace apps like Amazon fix all issues that shoppers have with online buying apps. How Do Online Marketplaces Work? Online marketplaces congregate buyers and sellers through apps like Amazon. While acting like digital middlemen, they bring buyers and sellers together to make transactions efficiently. Buyers can choose what to purchase and sellers can offer various products to customers. Because of the convenience Amazon offers, it is driving internet economies all across the world. By driving liquidity via commissions, value-added services, and advertising, online marketplaces have become the cash cow of different companies. These platforms have replaced all web sectors in terms of online traffic growth. These days, customers have more faith in online marketplaces as they offer a wide variety of products from both small and large sellers worldwide. Online marketplaces don’t need to maintain product descriptions, logistics, inventories, and product images as the responsibility is on the sellers. Sellers also get a fixed space for handing their orders and selling stuff. Buyers access the online inventory and check the real-time data about the goods that are updated timely. Types of Online Marketplaces Following are the major types of online marketplaces based on core focus: Horizontal Marketplace Horizontal marketplace sells many products and services to a wide range of customers across different industries. This marketplace follows the concept of one-stop shop, fulfilling various customer needs in one place. Most famous marketplaces like Amazon, eBay, AliExpress are the best examples for this category. Vertical Marketplace Vertical marketplace is based on a specific niche. This type of marketplace offers a range of products from several vendors but of a similar type. Thereby, a vertical marketplace can enhance customization and be different from others who sell many goods. Etsy is a good example of this marketplace that usually sells vintage and handmade products. Following are the types of marketplaces based on their target audience: Business-to-customer Marketplace Business-to-customer or B2C marketplace is a platform where sellers sell goods to consumers. Some common examples include Flipkart, and Amazon. Business-to-business Marketplace Business-to-business or B2B marketplace where wholesale suppliers sell goods to other businesses at a wholesale rate. Walmart and Alibaba are common examples. Customer-to-customer Marketplace Customer-to-customer or C2C marketplace is a platform where consumers sell goods to other consumers. A well-known example is Etsy. Must-Have Features of Marketplace Apps To develop a marketplace app like Amazon successfully, ensure to add most of these features: 1. Seamless Registration Process An easy registration process can retain many users on a marketplace app. You need to keep the entire registration process as easy and small as possible so the users don’t need to wait patiently to use your app. 2. Social Media Integration Integrating your app with social platforms is one of the best ways to allow users to use your marketplace app. Apart from the one-touch login facility, the users must get access to your app with only a few clicks through Facebook, Twitter, Gmail, and other different social platforms. 3. Advanced Search Options This essential yet simple feature helps you sell your goods efficiently. With effective and advanced search options, users can get many options. 4. Voice Search This feature is going to transform the search for products and services soon. You must optimize this feature the way that the products’ info must be compatible with the voice search parameters. 5. Add to Cart Add this feature to your marketplace app for the consumers who sometimes don’t buy a product immediately but like the add-to-cart option to save the product for future buying. 6. Multiple Payment Choices Each and every customer has a different payment choice. Hence, use various payment gateways to offer multiple payment choices to your consumers. 7. Push Notifications Push notifications keep reminding the users of what products they are missing. This is the best way to keep them stuck with your marketplace app. The application of the right push notification methods defines your app’s success. Hence, spend on a good push notification system to retain your customers. 8. Ratings & Reviews These features are necessary if you want to develop a marketplace app like Amazon. It adds a trust element in the genuineness of your products and services. Moreover, it helps consumers make a detailed buying decision while helping you understand the things that you need to work on. 9. Photo Shopping This feature helps buyers find a product even without knowing the brand or the product name. They can just use the picture to search for a product. Presently, many online biggies are using this feature. 10. Augmented Reality Integrate your marketplace app with AR technology. It helps your app offer visitors the scope to analyze the products and services visually before finalizing the payment. Now

With the arrival of Progressive Web apps, numerous organizations have begun using this technology to provide an intriguing user experience and connect to their target audience more rapidly. For this reason, PWA development services are becoming more popular in several industries. The eCommerce industry is one such segment that is reaping the benefits of the game-changing PWA technology. After all, it represents further development in mobile-driven businesses. The PWA platform helps eCommerce brands focus on improving their user experiences. It allows brands to develop three times quicker than an eCommerce website. According to the Statista reports, there has been an expectation that we can experience a vast development in mobile-driven commerce that will profit more than 400 billion US dollars by 2024. And Progressive Web Apps are the primary reason behind this growth in mobile businesses. What is a Progressive Web App (PWA)? PWA is a combination of the features of a website and an app. It’s a website that works and appears like a native application. It is quick, conveys push notifications, functions offline, and you can add it to your mobile phone’s home screen. Unlike a native app, a PWA is a blended method of creating a platform that works like an app and a website. You cannot download PWAs from an application store. But, they are prompt and easy to use, like native applications. Since mobile phones are the primary traffic source, especially for eCommerce stores, PWAs may seem to be a fantastic solution for sellers predicting more conversions. How Progressive Web Apps Are Beneficial for eCommerce Stores The advantages of PWAs for eCommerce businesses are countless. PWAs make the online buying experience as smooth as possible, and we can expect them to rule and change the prospect of mobile-commerce for the below-mentioned reasons. 1. Saves Time and Cost of Development As PWAs’ architecture rests on reusable codes, developers may use them over and over again. Where, to build an app you need to have different code for other platform. Furthermore, your app must fulfill specific needs to get approval from both platforms’ reviewers. If you want to use devices with various operating systems to target two groups, you should increase your efforts alongside money, time, and resources. 2. Amazing Marketing Scopes Search engines are making minor changes to their voice-based searches. Likewise, sellers should also fine-tune themselves. PWA is a great SEO approach that an app cannot manage even if it is available on the app stores. As PWA is a site in the native form, it improves searchability automatically. 3. Bridges Gap between Customers and Merchants With a Progressive Web App, users don’t have to download an app. Hence, it lowers the cognitive load that users usually encounter while undergoing the app downloading process. Now, users are more aware of the number of apps present on their mobiles. Since users get limited mobile storage space, keeping a minimal amount of mobile apps is the current trend. Users don’t like to install more apps if they already have a lot of apps on their phones. Having lots of apps on the mobile makes it slower, clogging the phone. For this reason, mobile-driven businesses are turning to PWAs more quickly. 4. Offline Functionality with Service Workers Cache and service worker APIs are the USPs of PWAs. Service workers operate in the background and are accountable for obtaining cache elements and sending notifications. They store new content in a browser’s cache and syncs local transformations to the local server. Therefore, even if your app users cannot be online because of a weak internet connection, PWAs would help standard navigation. 5. Saves Storage Space and Data Whether it is crucial for an eCommerce business, users always save their internet and data costs. In this aspect, PWA are saviors for eCommerce businesses. When an application might take 50MB storage space in the phone memory, a PWA would occupy a few MBs only. 6. Flexibility and Responsiveness The flexibility and responsiveness of Progressive Web Apps may impact your choice. PWAs have a responsive layout. So, no matter what gadget you use, your website’s design must comply with its resolution and size. Impressive user experience increases online sales and retains more promising buyers. Flexibility harmonizes with the mobile-first method depending on addressing the choices of your targeted mobile audience. The mobile-responsive websites have more scopes to attract users’ attention and engage them. 7. Automatic Updates and No App-Store Costs In a PWA, automatic updates work like a regular website update where all updating processes occur at the server end. And this enables the end-users to have an updated website application. Moreover, either your tech partner or you as a business owner would have to pay subscription costs to the application stores where you want to upload your native application. A PWA helps you abstain from these unnecessary costs without impacting your website’s visibility. Launching a Progressive Web App means you don’t need to depend much on the application stores and their terms and conditions. While a native app might not be visible to your users on the app stores, a PWA can be dealt with by the search engines to boost its visibility. 8. Easy to Maintain Suppose you need to develop individual applications for iOS and Play Stores. In that case, you may need to spend a considerable amount for hiring a developer on a prolonged period as an app requires continuous monitoring, regular error fixes, and up-gradation. On the other hand, PWAs save your pocket, and you can upgrade them by identifying their needs for various browsers. 9. Increased User Adoption To use an application, users first need to install it. And this includes an additional step in online buying. It results in a lower conversion rate. Using PWAs, the users don’t need to download any app. They only need to click on the website link and follow all guidelines shown on the device screen. 10. Secure Payments Security is one of the advantages PWA provides the eCommerce companies.

Google initially launched its UI library, Flutter, for creating native functional mobile apps that ensure smooth performance. The attractive features and characteristics of Flutter have attracted many developers to explore it for building apps. Although Flutter initially focused on creating cross-platform Android and iOS apps, it no longer has restrictions to build mobile apps only. Desktop and web apps are something now you can try making with Flutter. If you want to try Flutter for Web, this is the right guide for you. Without further discussion, let’s read on! A Brief Introduction of Flutter Flutter is Google’s UI library that helps build native performant apps across all devices, such as desktop, web, and mobile, via a single codebase. It uses Dart programming and combines Cupertino and Material Design to create an attractive user interface. The intriguing UI not just feels native but also can resemble the platform to perform naturally on any device. How Does Flutter Web Function? Flutter renders website apps similarly like it renders mobile apps for iOS and Android platforms. Flutter Web can turn a project into native code when you need to deploy it. It builds single-page web apps. However, you can have multi-pages, but if Flutter changes a web app to the native language, there will be a single index.html HTML file. So, how can you create multi-pages web apps? The Navigator works on the Stack data structure. Although Flutter Web is a single page, it can push many pages on a similar single native page. Measuring Flutter for Web’s Performance The Flutter developer community actively makes enhancements and changes to improve Flutter Web’s performance and bring it to a fixed release. Mainly two things can measure Flutter Web’s performance: first, it can render and manipulate massive amounts of data, and secondly, it features effects, transitions, and animations. Flutter developers have following two options of rendering engines to select from: DomCanvas CanvasKit These engines produce Dart code that turns to CSS and HTML for the execution of widgets. Apps built with DomCanvas have a lesser payload than the ones made with CanvasKit. The extra massive size for CanvasKit improves its performance by radical changes. So, it would help if you decided whether you want your users to wait a bit more to enjoy a better user experience. In a nutshell, in terms of performance, Flutter Web needs to improve more to meet the level of the performance of modern JavaScript frameworks and libraries like Vue, Angular, and ReactJS. When Does Flutter for Web Development Bring Benefits for Businesses? When it comes to building a web app, Flutter may be the right solution. Learn when it’s worthwhile to use the Flutter web for business. Mobile and Web Development at the Same Time Flutter is the right solution in case of building an app for the web and mobile at the same time. With Flutter, now it’s possible to create the entire product from a single codebase using a team of Flutter developers. Developers need to create responsive UIs, as the web and mobile apps will work on various screen resolutions and sizes. When a screen’s web version might require being entirely other than the mobile version, Flutter can support platform checks. It helps you render various screens on the web and mobile. It saves time, as web and mobile apps share standard translations, styles, logic, UI elements, and more. Reuse Code from an Already Built Mobile Application Flutter brings business value if you already have a mobile app and go for Flutter for Web development. In this matter, you can use current UI elements and logic to build web apps quicker than other web platforms. Your app’s web version does not need to execute every feature the mobile version has. Companion Applications Flutter Web also works as a companion to mobile applications. For instance, a demo application, your mobile app’s admin panel, or proof of concept uses standard code with a broader system made with Flutter. Should You Use Flutter Web When Mobile Apps Are Not in the Picture? Flutter helps you create engaging and performant web apps. But, it’s not ideal for static website pages. It is perfect for single-page interactive applications with heavy UI elements and animations. In terms of static website pages with lots of text, a higher standard website development process may result in better outcomes, quicker load times, and more feasible maintenance. Pros of Flutter Web Here are a few benefits of using Flutter for Web for your business: Flutter web can render animations, transitions, and graphical effects. It can manage massive amounts of data. Flutter provides excellent assistance for both Cupertino and Material design UI elements. It can execute a game engine for specific products with better physics and animations. Flutter offers PWA support. It renders animations in up to 60 frames/second. You can run JavaScript code from within Flutter Web. It’s a fantastic option if there is an SDK or JS library you have to explore. Flutter Web can integrate with current web apps as an embedded element. It provides a massive amount of commercial and open-source libraries on pub.dev. Cons of Flutter Web Flutter Web has a few shortcomings also as it is still under development. Let’s have a look: Flutter web is not SEO-friendly. Hence, in terms of product marketing on search engines, you may see better results on other web frameworks. Flutter Web does not maximize its full support for plugins. Since Flutter Web is still developing, you can see a slower app performance. The Hot Reloading feature of Flutter Web is tricky. You can either type webdev serve –auto-restart in the command line or refresh the page manually. Flutter web developers cannot modify produced JavaScript, CSS, and HTML code. It has restrictions on the support of Flutter APIs. Compared to classic web development, Flutter web’s load size may look poor. HTML’s minimum payload is 1.8 MB, and CanvasKit includes an extra 2MB to the payload providing better performance. How to Run Your Current Project

Choosing the right programming language is very important for any development project. Nowadays, Python and PHP are two popular programming languages that most businesses like to use for web development projects. When comparing these two, choosing one becomes a bit difficult. Although many websites are developed in PHP, Python has also becomes very popular in the last few years. But, which programming language is right for your web app – Python or PHP? In this blog post, we will discuss the basics of the two languages and then will proceed to their comparison. So, let’s get started! What is Python? Python is an open-source programming language that aims at object-oriented programming concepts. Guido Van Rossum developed this language in 1991. Currently, it is one of the most extensively used languages, providing high-level, easy-to-understand syntax.

The Best Practices for Mobile UX Design in 2022 Designing mobile UX needs understanding and knowledge of user expectations and requirements. The number of mobile device users will reach 6.9 billion in 2023, which showcases a constant development in the following years. Hence, you can’t skip learning the best mobile UX design practices. Let’s have a look at some of the best mobile UX design practices in 2022! 1. Navigation should be Simple The unique content and features have no use if your users cannot discover them. It would help if you created engaging and easy navigation. Implement easy-to-find elements so that users can navigate from one screen to another or return without issues. Make sure to design the navigation menu so that it doesn’t occupy lots of space on the screen. 2. Break down User Activities Try to respond to one major action per screen, such as selecting an item, signing in, giving parameters, confirming an action, etc. You can make it specific by using a different shape or color. If you incorporate any less important step, prevent it from contending with the important ones. 3. Follow Minimalism Minimalism is always in trend in the world of mobile UI/UX design. Building a simple method is not difficult. Since users search for ease of use and usability, you must not clutter screens with many interface elements. For better results, make a balance between unique functionality and a basic design. 4. Design for All Designing a good UX for all is one of the most crucial mobile UX design principles. Users can interact with their mobile devices in many ways. Hence, it would help if you designed the layout of the UI elements to be accessible and visible while interacting with a mobile device. You must not place buttons or any other features at the top, or bottom corners of the screens as these places are not easy to reach. 5. Make Scrolling Spontaneous Utilize a horizontal scroll for browsing through a catalog of products or showing data on an extended visual area that would not fit the screen. If there is more content available, give a visual indication and signify the scrolling direction. 6. Make Buttons Clickable Small touch controls are the miseries of users’ existence. They cannot save virtual screen space and, therefore, harm the user experience. Every OS has its button design options for better UX. In many cases, buttons of 44px height and 44px width work amazingly on every OS and mobile device. 7. Accept Familiarity Execute standardized, familiar icons and layouts to eliminate the users’ learning curve. Ensure that every UI element signifies its functions. For example, you can utilize an envelope symbol for triggering message sending and a phone symbol for the one-click call activity. Make sure to prioritize usability before creativity. 8. Provide User Support Whenever users face issues, ensure to solve their queries. Use different methods to assist them through your application, from chatbots and live chats, via in-app native FAQs to click-to-call client support buttons. 9. Keep a Constant Experience If your app is available on different platforms or has its web version, ensure users get a consistent, smooth experience. It must be worth comparing with other devices when somebody wants to shift, so it will not be difficult to suit. Moreover, it makes your UX design more noteworthy, as users become more familiar with it apart from the device. 10. Select the Right Font Selecting the right font is as crucial as building the visual components of your device solution. Picking the wrong fonts can spoil your design. Hence, opt for a font that works perfectly in several weights and sizes. According to tech biggies like Apple and Google, you should keep the font at 12 points. It helps users read the info on the screen without zooming in. Moreover, it helps them keep their device at a comfort-giving distance for viewing. 11. Collect User Feedback Your main purpose as a designer is to provide users with a good UX. And you can authenticate your ideas by asking users about them. Trustworthy feedback will help you decide what works and what does not. This info will help you decide what to change. Applying analytics to your app will give all data to boost user experience effectively. 12. Enable Sufficient Spacing and Padding A small screen does not mean you need to use less space or smaller text. Prevent texts or

Angular launched the all-new Angular 13 on November 3, 2021. Considering all the previous releases, we can say it is one of the most streamlined and previously planned upgrades for a broadly accepted TypeScript-based web framework. The release has brought several essential updates that can be useful for Angular development. If you want a comprehensive view of what’s exclusive in Angular 13, let’s have a glimpse of this version’s top highlights and features with more details! Top Features and Changes Released in Angular 13 There is a lot to know about the latest version of Angular. So, let’s take a closer look at Angular 13 with all its newly added features and core updates. 1. Support for TypeScript 4.4 Angular v13 now support TypeScript 4.4. It means now we can use many fantastic language features. Moreover, they stopped supporting TypeScript 4.2 and 4.3 also. One breaking change in TypeScript 4.4 that is advantageous for Angular apps is that it no longer implements setters and getters to get a similar type. 2. Enhancements to Angular Tests The Angular team has made some noteworthy changes to TestBed that currently functions properly to tear down test environments and modules after every test. As the DOM now experiences cleaning after tests, developers can anticipate more optimized, less interdependent, less memory-intensive, and quicker tests. 3. 100% Ivy and No More Support for View Engine Angular 13 does not support the View Engine. The all-new version is now 100% Ivy. Now that there is no View Engine-specific metadata or older output formats, it eliminates the codebase complicacy and maintenance costs in Angular 13. The framework has converted all internal tools to Ivy in advance so that this change can function seamlessly. Ivy assembles every component individually, which accelerates development times. There is no more requirement of using ngcc (Angular compatibility compiler) for the libraries created using the latest APF version. The development team can expect quicker compilation as there is no more requirement for metadata and summary files. 4. Ergonomic APIs Angular v13 has reduced the load time using ergonomic code-splitting APIs and granular code disruption at a component level. The new release of ESBuild has also brought an enhancement of performance. ESBuild is a highly rapid JavaScript bundler. Now, it works with terser to optimize worldwide scripts. It supports CSS source maps that allow optimized global CSS also. Moreover, this JS bundler supports other framework languages like Vue, Svelte, and Elm. 5. Angular CLI Enhancements The Angular CLI is one of the fundamental pieces of the Angular Puzzle. Few developers can handle the complicacy of the modern web development ecosystem in the world, and the Angular CLI safeguards them from most of it. With the launch of Angular v13, this framework now supports persistent build cache by default. It’s a feature that caches build results on disk. It causes up to 68% enhancement in development speed. You can enable or disable this feature in current Angular apps. 6. Changes to the Angular Package Format(APF) The Angular Package Format (APF) specifies the format and structure of the Angular Framework packages. It’s a great approach to packaging every third-party library in the web development ecosystem. Angular 13 brings a new version of the APF, and we find some significant changes in it: It creates Ivy partial compilation output. There is no more production of UMD bundles. It produces ES2020 output. It utilizes the package exports with the sub-path pattern feature from Node.js to display several available outputs at every entry point. 7. Changes in Framework and Dependency Updates Angular 13 also boasts some crucial changes and updates. Now, RxJS v7.4 is the default for applications built with ng new. Current applications utilizing RxJS v6.x will need to update manually using the npm install rxjs@7.4 command. 8. Component API Updates Now, you can build dynamic components using less boilerplate code due to the improved ViewContainerRef.createComponent API. If you use Angular 13, you don’t have to use ComponentFactoryResolver. Here’s an example of creating dynamic components using previous versions of Angular: In Angular 13, this code can become using new API: 9. No Longer Support for Internet Explorer 11 For enjoying the benefits of native web APIs and features of modern browsers like CSS variables and web animations, the Angular framework has cut off the support for IE11. It provides a quicker load and smaller bundle size for applications and an enhanced user experience as there are no IE-specific polyfills and no requirement for distinctive loading. It’s a notable change for some institutions or authorities that still run Internet Explorer 11 and haven’t yet moved to Microsoft Edge or other modern browsers. 10. Accessibility Update in Angular Material The new version of Angular has brought an Accessibility (A11y) enhancement in Angular Material. The team has assessed and checked all MDCs (Material Design Components) for improved accessibility. For instance, radio buttons and checkboxes now have larger touch sizes, and other elements feature higher contrast modes. 11. New Type of Forms The release of Angular v13 highlights a new type of form: FormControlStatus. It accumulates all status strings for form controls: For instance, the type of AbstractControl.status is presently FormControlStatus in place of string. The type of StatusChanges is now Observable<FormControlStatus> in place of Observable<any>. 12. Inline Support for Adobe Fonts The introduction of Angular 13 also highlights inline support for Adobe fonts. These fonts can boost an app’s functionality by accelerating the FCP (First Contentful Paint). Now this change is accessible to everybody by default. You only need to do ng update. 13. Improvements in Localization $localize is a consistent API. Developers use it to produce an effective way for in-built internationalization (i18n) and tag messages for translation in code and templates. How to Update to Angular Version 13? To update to Angular version 13, you need to download Angular 12. Then, you can update to the latest v13 following this link: https://update.angular.io/ for a detailed guide. Conclusion The Angular team tries to release a new version update every six

Organizations have widely accepted DevOps services to refine the quality and promptness of software delivery. DevOps helps the development and operations team to work effectively. It helps teams plan better, communicate and process projects successfully. Automated testing played a key role in standardizing and speeding DevOps processes. Here we will talk about DevOps, testing in DevOps, benefits and best practices of DevOps testing strategies. What is DevOps? While Agile and DevOps are two different processes, one can find familiarity between the two as those who are working on Agile will likely adopt DevOps effortlessly. The term DevOps stands for development and operations, and works on continuous development. i.e the software being built, deployed, tested, verified and delivered on the ready to use production environment. DevOps is an exercise focusing on modernizing the areas ensuring its progress. The conceptualization is to accelerate the delivery of working software and eliminate the bottlenecks. How has Testing Worked Traditionally? Testing is not new in the software business. However, testing in a traditional environment is not the same as testing in a DevOps environment. Traditionally, in the waterfall model, software testing was performed as per the following phases: Requirements Analysis Design Implementation Testing Deployment Maintenance Here, software tester do the testing work apart from the development team so it becomes difficult and expensive to fix any bugs discovered during the testing stage. Hence, it’s uncertain whether the required quality and standard of the development could be conserved within the allocated time frame. Why is QA Essential to DevOps? DevOps is a collaborative approach and integration of QA in the development and testing cycle plays an essential role. In DevOps, quality is ensured throughout the project cycle and highly motivates continuous testing. In the traditional testing approach, the quality team was the last to enter the project to verify the application and it had no role in the initial phases of application development. The pattern is changed through DevOps, now, the latest development code is pushed to production by the QA and testing team with ease, while the deployment is ensured by the DevOps. As a result, quality assurance is no longer limited to logging bugs but is now involved in ensuring the smooth release of applications. The role of QA is changed with DevOps: QA permits and directs to check the quality and performance of the application in a faster and secure way before the delivery. Automation guarantees faster delivery. Providing functional build to clients at any stage of the development life cycle would be next to impossible if quality is not assured at every stage.  The need of the organization is to build the right DevOps testing strategy to deliver successful software solutions and operations. How to Create a DevOps Workflow? One size does not suit all solutions due to the stretch in requirements and objectives of the teams. Thus, it becomes important to construct a DevOps workflow for the team. Below are two general scenarios to integrate DevOps workflow: Scenario one: To develop a workflow for Greenfield software development. As the development team would be starting fresh, It would be easy to automate the testing operations and processes with growing application and team size. Scenario two: To develop a workflow for Brownfield software development. As there would be an existing codebase and team, DevOps need to be adapted for maintenance. This would take some extra effort to rebuild the workflow in comparison to Greenfield software development. The possible efforts are to contemplate the tasks through the Kanban board. Picturing the tasks with a Kanban board helps us to identify and address these issues to accelerate the workflow. Detailing segregated tasks on boards allows the team to work together, resulting in developing the functional test strategies. For the most part, this revamps collaboration between DevOps and TestOps. Benefits of DevOps Testing Strategy DevOps testing works on a continuous testing approach. Here are the benefits you can expect from a robust DevOps testing strategy. 1. Covers functional and non functional testing The functional testing types involved with DevOps are Unit testing, Integration testing, Regression testing, API testing and Cross browser testing. Likewise, the non functional testing types such as usability, security, reliability, scalability testing are involved in DevOps. 2. Continuous analysis of risk areas Testing the build in each and every version clears out the risks that can hamper the delivery of builds on time. The evaluation of build in a continuous manner would help to eliminate risks at every single stage. 3. Better user experience Routine feedback from customers helps developers to understand and fix problems and make continuous updates to the application. It gives an ability to create test cases as per functional point of view, which are executed as per requirement to evaluate the end user’s experience. DevOps testing aid to keep the software sturdy and stable. 4. Platforms coverage As DevOps make use of test automation, it ensures the platform coverage by integrating and using the right test automation tools. This approach helps to deliver at a good speed. 5. Fast feedback and delivery The need of the hour is to get the feedback within a day in order to make the fixes at the same time. Traditionally, developers need to go back to code after weeks of building it due to late feedback. DevOps leads to faster feedback and faster delivery. 6. Stable and quality software Organizations have adopted DevOps with open hands. The interesting part about DevOps is that each team member plays an important and equal role. The DevOps team has a common goal of delivering secure, stable and quality software. Best Practices for Testing in DevOps Choosing a bedrock for test automation is challenging for organizations. A comprehensive evaluation of the software is vital to create a DevOps testing strategy. Below are some of the key points to help shape a successful test strategy. 1. End to end tests It is very importantto test the functional areas and therefore we need to write end to end tests. End to end tests cover the real
