Assessing the Impact of Service Workers on the Energy Efficiency of Progressive Web Apps

Progressive web App is a web-based application development that includes the application of the latest technology from a browser that can be accessed quickly into one application without having to install. Progressive web applications can run like mobile applications in general, and the user interface is like using native applications. Progressive web app was invented in 1990. Progressive web App uses the latest Technology to produce web apps that provide a better User Experience and User Interface than mobile native. Progressive web app that is supported by a system called Service Worker, where the technology provides Offline Functionality, Notifications, Content Updates, Connectivity Changes and others. So that in a slow connection or an unstable connection you can access websites quickly and have the same appearance as the last time you opened the application via a Web Browser. This progressive web app can optimize web app performance to allow users to have an accessible experience with quickly and easily through browsers such as notebooks, personal computers or through mobile devices. This progressive web app is a service worker that allows a web app that can be run through all existing browsers and has a fairly simple and transparent process. So that the page that is opened, on the service worker site which is a proxy client that can be written in javascript, as well as being able to cache the assets needed for offline support which can determine certain events to activate the service worker such as push notifications, camera, and background sync. Keywords : Progressive Web Apps, Web, User Interface, Native Apps, User Experience

Mobile applications are an integral part of our daily life. From ordering food to online banking, they are used for a multitude of daily tasks. Currently, there are two main ways to build mobile applications — native apps and Progressive Web Apps (PWAs). Native apps are built separately for Android and iOS, while PWAs are web-based apps that function similarly to native apps within a browser environment. This paper compares these two technologies based on performance (speed, memory, battery), user experience (ease of use, satisfaction), and development efficiency (cost, maintenance). Real-world examples like Starbucks PWA, Twitter Lite, and Ma-Ease (a native Android app) are used to clearly illustrate these differences. The study found that native apps are superior in terms of performance and user experience, but PWAs are more cost-effective to develop and simpler to maintain. The System Usability Scale (SUS) scores for native apps were 83.2 (Excellent) and those for PWAs at 76.5 (Good). This paper assists developers and organizations in deciding which technology to choose based on their needs and budget.

Growing use of the cell phones and tablets over the computer for humans’ daily life has increased the development of mobile apps. Different paradigms have been introduced to develop a mobile app. Up till now, the major paradigms have been introduced are native apps, hybrid apps, web app and the new trend namely progressive web app (PWA). Each methodology has its pros and cons. This paper discusses about native development issues and how web app aimed to solve these problems. The hybrid apps will be discussed as a solution of cross-platform development problem of native apps. In addition, problems of web apps and the gap between web app and native apps will be introduced. PWA is supposed to bridge the gap between native apps and web apps. The main technologies –service worker- will also be discussed.

App development is a steadily growing industry. Progressive web apps (PWAs) constitute a technology inspired by native and hybrid apps; they use web technologies to create web and mobile apps. Based on a service worker, a caching mechanism, and an app shell, PWAs aim to offer web apps with features and user interfaces similar to those of native apps. Furthermore, technological development has created a greater need for accessibility. An increasing number of websites, even government ones, are overlooking the need for equal access to new technologies among people with disabilities. This article presents, in a systematic review format, both PWAs and web accessibility and aims to evaluate PWAs’ effectiveness as regards the corresponding accessibility provided.

Mobile software development is an emerging technology and so are the strategies to build them. This paper focuses on the budding technology i.e. Progressive Web Apps (PWAs), which bridges the gap between web and native mobile apps. Service Worker is the backbone of any PWA. It enables caching of memory, offline access, and other gem features. To prove that caching memory improves the performance, tests have been performed. Taking the advantage of Google's Lighthouse (beta) tool, metrics have been calculated and solutions to improve them are suggested. We has demonstrate the service worker and its impact on cross platform approaches and compare android, iOS and PWA performance growth.

This article analyzes and contrasts the use cases, Cultivation Methods, Tools, and User Experiences of Progressive Web Apps (PWAs) and Mobile Native Applications. It notes that since 2015, the use of PWAs has surged as a result of faster download times, offline usability, lower development costs, and enhanced engagement. Key PWAs For the Building of PWAs includes Service Workers, Web App Manifests and Responsive Web Design; the article showcases practical code examples for registering service workers, and handling notifications, as well as caching resources for a seamless user experience. Popular frameworks for PWA development includes Angular, React and Vue.js. For the user interface, Framework7, React Native, Ionic and Onsen UI provide a native user interface and feature design and offer enhanced usability. To empower PWAs, best practices include notifications and caching for heightened user reliability. Exercises in the article include tables showing the advantages and disadvantages of methods, tools sticks, and practices which outline the best routes for the developers. In essence, the article states that PWAs provide high-performance levels, are scalable, secure, and user-engaging, thus going through the same competition as native applications besides maintaining development and maintenance costs to their lowest. As the browser capabilities advance, it will become an ever-important chair for modern web development.

Progressive Web Apps (PWA) are a new class of Web applications, enabled for the most part by the Service Workers APIs. Service Workers allow apps to work offline by intercepting network requests to deliver programmatic or cached responses, Service Workers can receive push notifications and synchronize data in the background even when the app is not running, andtogether with Web App Manifestsallow users to install PWAs to their devices' home screens. Service Workers being a Web standard, support has landed in several stand-alone Android Web browsersamong them (but not limited to) Chrome and its open-source foundation Chromium, Firefox, Edge, Opera, UC Browser, Samsung Internet, andeagerly awaitediOS Safari. In this paper, we examine the PWA feature support situation in Web Views, that is, in-app Web experiences that are explicitly not stand-alone browsers. Such in-app browsers can commonly be encountered in chat applications like WeChat or WhatsApp, online social networks like Facebook or Twitter, but also email clients like Gmail, or simply anywhere where Web content is displayed inside native apps. We have developed an open-source application called PWA Feature Detector that allows for easily testing in-app browsers (and naturally stand-alone browsers), and have evaluated the level of support for PWA features on different devices and Web Views. On the one hand, our results show that there are big differences between the various Web View technologies and the browser engines they are based upon, but on the other hand, that for Android the results are independent from the devices' operating systems, which is good news given the problematic update policy of many device manufacturers. These findings help developers make educated choices when it comes to determining whether a PWA is the right approach given their target users' means of Web access.

With the advancement in technology in each counting second new solutions to new problems comes into the picture and PWA are one of them which came as an alternative to the current leading technologies like android and Web, combining features of both the technology and overcoming the shortcoming of both the technologies. Progressive Web Apps are web apps that are built using the Service Workers API which can work offline by intercepting HTTP requests and delivering cached responses. The concept of progress is an approach that takes advantage of the capabilities of the environment instead of having rigid requirements. PWA is built without requiring the installation of a native app and works seamlessly across various platforms. Many Android Web browsers support Service Workers, which is a standard component of the PWA landscape. This paper aims to analyze the current state of support for PWA features in Web Views and how it fits into the overall web experience.KeywordsProgressive web appsInstall abilityIn-app browsersInformation technologyService workerApp ShellNative android application

Progressive Web Apps or PWAs can be described as the next big advancement in site design and building, as they give web application - like functionality within a web browser without the need for app downloads. This paper discusses how PWAs build the path between normal mobile applications and web applications using service workers; web application manifests, and contemporary JavaScript frameworks. PWAs have functionalities like offline capability, push notification, and background refresh that address the users' engagement; scalability and dependability of web application that facilitate the functionality of the PWAs. The given features enable PWAs to provide an unbroken and captivating interface to individuals, even during certain circumstances when one has intermittent or no Internet connection. The research aims to evaluate the increasing engagement of users with the help of PWAs and what parameters should be involved: time to loading, interactivity, and re - engagement rates. The paper assesses the development of PWAs and measures how organizations such as Twitter, Uber, and Flipkart have adopted PWAS to increase their profits, client satisfaction, and performance based on research studies. This research gathers data from PWA developers to understand the motivation and barriers to its use. Studies show that applying PWAs yields significant performance enhancements as they cache data and do not require a constant Internet connection. In addition, the study shows how push notifications and background sync features help enhance user engagement since clients are reminded to be active without having to install an application. However, the various benefits of this research bring some understanding and realization of certain drawbacks like technical difficulties, support from only a limited number of browsers, and perceived impressions, which may slow its uptake.

The mobile apps have been reaching a huge success on the mobile market. This opportunity attracted a lot of interested companies to have their own optimized mobile apps for all major mobile operation systems. However, these developments are expensive when developed natively for each mobile platform. New improvements done on the web technologies, allowed more features and capabilities than previously was only possible on apps that was developed natively. This started new possibilities on consolidate all developments only on web apps, that are apps that runs on web browsers. This paper intends to understand which evolutions, capabilities and limitations exists on developing a web app to run in all devices. We present the new concept of Progressive Web App, created by Google, in a way to normalize all web developments. It will be introduced the major advantages on developing the apps centralized as a Progressive Web App, comparing on developing the same solution for each different mobile platform. It will be also described the current state of web technologies and in which preferable scenarios the Progressive Web Apps are a strong alternative to the mobile native apps.

The problem of correspondence cannot be separated from the ease, accuracy and speed of the processing process. In research from Riswandi Ishak and H. Trizaka, they proposed report management software as well as notification of disposition and monitoring of correspondence as a solution to correspondence problems. However, there are shortcomings in the notification process for the disposition of correspondence, which requires the software to be actively open. In research, P. Dwi proposed a notification solution with Firebase Cloud Messaging (FCM), so that it can send notifications as long as the browser is active and connected to the internet, even without opening the software. There is a problem currently when the software becomes unstable when the internet connection is bad or offline. Progressive Web Apps (PWA) offers the concept of web-based application development by implementing browser technology such as service workers and app manifests. PWA is capable of displaying pages offline but cannot save, change, or delete data in the database. The test results of this research used Lighthouse and showed an average score of 100 on the PWA criteria, 85 on the performance criteria, 97 on the accessibility criteria, and 100 on the best practices criteria. Additional results obtained by implementing PWA mean page loading times are 26.6% faster with cache and service workers. The PWA and FCM concepts provide the best experience in using Mailing Software even with minimal internet connection or offline. This strategy was chosen to still get a fast response when running the mail processing software.

With the evolution of mobile devices and app eco system, all major content providers develop services in native apps and web-apps. Web-apps have an inherent advantage of platform independent and uniform experience across devices, but the page load time, battery usage, and bandwidth consumption have to be improved. To solve some of these issues, there has been an introduction of Progressive Web Apps (PWA) by content providers. PWA apps use an effective caching policy on web resources based on its property. But the webpages are overwhelmingly non-PWA compliant. There is a need for non-PWA web pages to be effective in bandwidth utilization so that we can avoid the exchange of needless resources. This paper proposes a new method to inject a service worker into a webpage at Proxy Servers. This service worker is packaged along with non-PWA webpage as a response to web browser requests. The web engine then runs the service worker to identify stale web resources which in turn will be helpful to avoid transfer of redundant web resources. The proposed approach was evaluated using top 25 Non-PWA sites from Alexa 100 websites for one month. It saved an average of 25% data traffic and also provided an offline experience of these websites. This proposal can be further extended to create a generalized framework for seamlessly converting Non-PWA apps to PWA apps.

Progressive Web App (PWA) is a new approach to the development of mobile applications (apps) which was proposed by Google in 2015. It combines technology resources of both web and native apps. Meta-design is an End-User Development (EUD) approach from which end-users participate actively in a system's design process. Yet, PWAs are a recent technology and the impacts of associating EUD and PWAs has been little exploited. As the traditional PWA approach is limited regarding users acting as co-designers, we propose the PWA-EU approach, an extension of the traditional PWA architecture that includes EUD concepts. PWA-EU provides contributions in two lenses. First, the proposal was designed to be used by developers on the design/development time. Second, the app developed using PWA-EU approach will allow end-users to select design preferences, which makes them participants of the app's design. This active participation of end-users on the design is possible due to the meta-design concepts present on the PWA-EU approach. In this article, we present the PWA-EU approach and its evaluation in the perspective of developers/designers. For the evaluation, we grouped participants according to their professional background. The results also indicate that novice developers had a reasonable performance with only one hour of training.We conclude that even novice developers could achieve better performance in a real-life environment, in which they would have more time.
