Microsoft Edge: The Future of Progressive Web App (PWA) Testing

Microsoft Edge

The advent of Progressive Web Apps (PWAs) has disrupted how web applications are viewed. PWAs render the user experience frictionless, native-like, and fast. During the massification process of using PWAs, organisations need to ensure that a PWA serves reliably and consistently across devices and platforms. That’s where a mobile site tester and cloud testing come up; it throws a reliable and scalable solution for PWAs. 

For example, a mobile site tester determines if the PWA is responsive and usable on various mobile devices and browsers. Microsoft Edge has been at the forefront of adopting PWAs and providing strong-backed PWA features that empower developers to build immersive and engaging user experiences. 

Now, with the capability of Service Worker and push notifications, developers can finally build those PWAs with the same native app-like user experience. Web App Manifest, Microsoft Edge Developers Microsoft Edge supports the Web App Manifest, which empowers developers to describe the behaviour and appearance of their PWAs.

Introduction to Progressive Web Apps

Progressive Web Apps (PWAs) are game changers in web development. These are solutions meant to complement our modern-day web technology stack, including HTML, CSS, and JavaScript, in building a familiar and accessible platform for web developers. Unlike traditional web applications, the PWAs can be installed directly on a user’s device from a web browser, providing uninterrupted and smooth experiences.

One of the key benefits of PWAs is that they assure native app-like functionalities without making a separate app for mobile. Loading faster, providing offline access, and receiving push notifications are what people have come to expect from an application. When combined with these features, PWAs allow a richer yet more reactive user experience, improving the online presence.

PWAs also provide a cost-effective way for organisations to reach and engage users. Through the development of only one PWA, an organisation can ensure the compatibility of its applications with all devices and platforms, eliminating the need to develop and maintain multiple native applications. 

This doesn’t just save time and resources; it also drastically reduces the complexity of development and maintenance and is, therefore, a lucrative option for all-sized organisations.
