About

An implementation of the cache only request strategy.

This class is useful if you already have your own precaching step.

If there is no cache match, this will throw a SerwistError exception.

Parameters

  • cacheName — Cache name to store and retrieve requests. Defaults to Serwist’s default cache names.
  • plugins — Plugins to use in conjunction with this caching strategy.
  • fetchOptions — Options passed to non-navigation fetch() calls made by this strategy.
  • matchOptions — The CacheQueryOptions passed to any cache.match() or cache.put() call made by this strategy.

Usage

import { CacheOnly, Serwist } from "serwist";

const serwist = new Serwist({
  runtimeCaching: [
    {
      matcher: ({ url }) => url.pathname.startsWith("/app/v2/"),
      handler: new CacheOnly(),
    },
  ],
});
