1219072 - Use a Service Worker to Cache Frequently Used Resources

Status: RESOLVED WONTFIX

(developer.mozilla.org Graveyard :: General, enhancement)

Description

[David Walsh :davidwalsh]

What problem would this feature solve?
======================================
We could make MDN's front end significantly faster with front-end assets using a Service Worker.  Files could include:

*  CSS Files
*  JS Files
*  Fonts
*  Design images

We do a great job with minification and async'ing of resources right now but a Service Worker would save numerous requests and downloads.

Who has this problem?
=====================
All visitors to MDN

How do you know that the users identified above have this problem?
==================================================================
Because we aren't using Service Workers.

How are the users identified above solving this problem now?
============================================================
They aren't; even when a file is in cache, a request is made to the server to check cache status.

Do you have any suggestions for solving the problem? Please explain in detail.
==============================================================================
We can implement a Service Worker with cache-busting capabilities (either by version or by expiration) for clients with adequate fetch and navigator.serviceWorker features.

Is there anything else we should know?
======================================
