Progressive enhancement

Follow the principle of progressive enhancement, ensuring that your PWA works across a range of devices and browsers while taking advantage of advanced features on capable platforms.

App shell architecture

Employ the app shell model to separate the application's core structure from the dynamic content. This enables faster loading times and a smoother user experience, especially on repeat visits.

Caching strategies

Caching is crucial for PWAs because they aim to work seamlessly, even in offline or low-network conditions. Service workers allow developers to control how resources are cached and served.

Responsive design principles

Ensure your PWA is designed to work seamlessly across various devices and screen sizes. Use responsive design principles that could adapt your layout and content for different viewports.

Comparisons:

The latest Progressive Web Apps (PWAs) have gained a huge popularity as a modern approach for building web applications. These have provided a native app-like experience and even turn out better than many traditional websites. Let's take a look:

PWA vs. Native apps

PWAs are accessible through web browsers, whereas the Native apps need to be developed separately. Users can install PWAs directly from the browser. On the other hand, the Native apps are typically downloaded from app stores.

PWA vs. Traditional websites

PWAs are designed to be highly performant. Traditional websites may rely solely on the server for content delivery. PWAs are inherently responsive, adapting to various screen sizes and devices. Responsive design is a common practice for traditional websites.

Advantages and disadvantages of PWAs

PWAs are designed to work seamlessly across different devices and platforms, including desktops, tablets, and smartphones. This ensures a consistent user experience.

PWAs often provide faster load times and smoother interactions than traditional web applications.

PWAs may not have the same level of integration with device features and APIs as native apps. This can result in a less immersive user experience in some cases.

PWAs don't go through traditional app store distribution; they may need more visibility than apps available in major app stores.
