What's the difference between using the Service Worker Cache API and regular browser cache?

Question

In my Progressive Web App, should I be using the Cache API in a service worker for my static assets, or should I just rely on the browser\'s native cache control for these?

Answer 1

A major advantage of the service worker cache API is that it gives you more detailed control than the built-in browser cache does. For example, your service worker can cache multiple requests when the user first runs your web app, including assets that they have not yet visited. This will speed up subsequent requests. You can also implement your own cache control logic, ensuring that assets that are considered important are kept in the cache while deleting less-used data.
