Methods

Methods

get

  • Retrieves a Response object from the cache. You should resolve with undefined if the cached value is not found, expired, or invalid. Do NOT reject the returned Promise.

    example
    const store = stores.indexedDB({store: 'my-objects'});
    const ignore = () => {};

    export const cache = {
      async get(request) {
        return await store.get(request.url).catch(ignore);
      },
      async set(request, response) {
        return await store.set(request.url, response).catch(ignore);
      }
    }

    Parameters

    • request: Request

      Contains information you can use to create a cache key. Typically, the url is unique enough to act as a key. See the example code.

    Returns Promise<Response>

    Promise resolved with undefined if the key could not be found in the cache or is invalid; otherwise, resolved with the Response object passed to Cache.set.

set

  • Stores a Response object in the cache. Resolve the returned promise when the object has been cached OR if the caching operation fails. Do NOT reject the returned Promise.

    example
    const store = stores.indexedDB({store: 'my-objects'});
    const ignore = () => {};

    export const cache = {
      async get(request) {
        return await store.get(request.url).catch(ignore);
      },
      async set(request, response) {
        return await store.set(request.url, response).catch(ignore);
      }
    }

    Parameters

    • request: Request

      Contains information you can use to create a cache key. Typically, the url is unique enough to act as a key. See the example code.

    • response: Response

      The Response to cache. This is the value that should be returned from Cache.get.

    Returns Promise<void>

    A promise resolved when the value is cached.
