Usage
import { CacheableResponse } from "serwist";
const cacheable = new CacheableResponse({
statuses: [0, 200],
headers: {
"X-Is-Cacheable": "true",
},
});
const response = await fetch("/path/to/api");
if (cacheable.isResponseCacheable(response)) {
const cache = await caches.open("api-cache");
cache.put(response.url, response);
} else {
// Do something when the response can't be cached.
}
