Network Information

Optimize a PWA based on network speed

The NetworkInformation API provides a way to access and retrieve information about a device's network connection, including details about the type of connection (like cellular or WiFi), its speed, and data usage, enabling your PWA to optimize their behavior based on the user's network conditions.

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.
