Use Cases

• Media Streaming Quality: A video streaming PWA can dynamically adjust the quality of the video being played based on the user's network speed. If the network is slow, the service can automatically switch to a lower resolution to prevent buffering.
• Image Loading: An image-heavy PWA can load lower resolution images or use image placeholders if the user's network is slow, ensuring faster page load times and a smoother user experience.
• Prefetching Resources: A PWA can prioritize fetching and caching essential resources (like scripts, stylesheets, or images) that the user is likely to access next, based on the available network speed.
• Offline Support: Progressive web apps can store essential data locally when the network is fast, allowing users to continue using the app even when the network connection is lost or slow.
• Background Sync: Applications that require synchronization, such as email clients, can take advantage of faster network conditions to perform background sync tasks and keep the user's data up to date.
• Real-time Collaboration: Collaboration tools can adjust the frequency of real-time updates based on network conditions. In slower networks, updates can be batched to reduce the strain on the connection.
• Form Handling: Web forms can provide immediate feedback and validation checks when the network is strong but switch to a more lenient validation approach when the network is slow, preventing frustration for the user.
• Interactive Content: Games or interactive applications can adjust the complexity of gameplay or the level of graphical detail based on network conditions, ensuring a smoother user experience.
• Dynamic Content Loading: Infinite-scrolling websites can load a smaller number of items per request when the network is slow to prevent excessive data usage.
