CacheStorage

Undici exposes a W3C spec-compliant implementation of CacheStorage and Cache.

Opening a Cache

Undici exports a top-level CacheStorage instance. You can open a new Cache, or duplicate a Cache with an existing name, by using CacheStorage.prototype.open. If you open a Cache with the same name as an already-existing Cache, its list of cached Responses will be shared between both instances.

import { caches } from 'undici'

const cache_1 = await caches.open('v1')
const cache_2 = await caches.open('v1')

// Although .open() creates a new instance,
assert(cache_1 !== cache_2)
// The same Response is matched in both.
assert.deepStrictEqual(await cache_1.match('/req'), await cache_2.match('/req'))

Deleting a Cache

If a Cache is deleted, the cached Responses/Requests can still be used.

const response = await cache_1.match('/req')
await caches.delete('v1')

await response.text() // the Response's body
