Understand how the network-with-cache fallback strategy combines using assets stored in the cache and making network requests.
We'll cover the following
How it works
The network-with-cache-fallback strategy, also known as the network-first strategy, is a technique for handling requests in a service worker. Implement it using the following steps:
- Listen to requests in the service worker’s
fetch

- Return it to the requester if the network response is received successfully.
- Search for the request in the cache and return the response if available—if the network request fails.
The slides below illustrate the steps to implement this strategy.
