A progressive web app (PWA) is a type of website built with modern web technologies to deliver an app-like experience to users. It's a key concept in modern web development.
What is Progressive web app?
A progressive web app (PWA) is a website that functions like a native mobile application. It uses service workers and web app manifests to provide features such as offline access, push notifications, and the ability to be installed on a device's home screen.
Why is this important?
For freelancers, especially developers, understanding PWAs is crucial. Clients often seek cost-effective solutions that work across all devices. Building a PWA can be a faster, more affordable alternative to developing separate native iOS and Android apps.
How does it work?
PWAs work by caching key resources on your device using a service worker script. This allows the app to load instantly on repeat visits and function without an internet connection. Users can 'install' it from their browser, creating an icon on their home screen.
Pros and cons
Key advantages include a single codebase for all platforms, lower development cost, and improved performance. Potential drawbacks are limited access to some device-specific features compared to native apps and varying support across different web browsers.
Conclusion
Progressive web apps represent a significant evolution in web technology. For freelancers, offering PWA development is a valuable skill that meets client demand for versatile, engaging digital products. It bridges the gap between websites and mobile applications effectively.
