Ship CacheNetworkRace as part of workbox-strategies

[jeffposnick]

Library Affected: workbox-strategies

We currently have code for a "cache and network race" strategy in our docs. The entirety of it looks like:

import {Strategy} from 'workbox-strategies';

class CacheNetworkRace extends Strategy {
  _handle(request, handler) {
    const fetchAndCachePutDone = handler.fetchAndCachePut(request);
    const cacheMatchDone = handler.cacheMatch(request); 

    return new Promise((resolve, reject) => {
      fetchAndCachePutDone.then(resolve);
      cacheMatchDone.then((response) => response && resolve(response));

      // Reject if both network and cache error or find no response.
      Promise.allSettled([fetchAndCachePutDone, cacheMatchDone]).then((results) => {
        const [fetchAndCachePutResult, cacheMatchResult] = results;
        if (fetchAndCachePutResult.status === 'rejected' && !cacheMatchResult.value) {
          reject(fetchAndCachePutResult.reason);
        }  
      });
    });
  }
}

Some folks have asked if we could ship it as part of workbox-strategies to make it more "official."

Off-topic for this PR, but when would it be the case that the disk is slower than network? On slow and old HDDs?

Hey, I am interested in this issue. Could you guide me a bit? From where should I start?

Hello, I'm new to open source and I would like to give this a try! If I understood the issue description correctly, the above-mentioned 'cache and network race' code snippet needs to be integrated with workbox-strategies. Please correct me if I am wrong and I would like to start working on this asap.

Jeff left Google 8 months ago. The new maintainer finally confirmed the other day that workbox has been deprecated.

Workbox is not deprecated. It is understaffed, we are not releasing a new version this year, but it is in our roadmap and we want to find a path via the community or another organization to staff it better.
