Description

The issue I'm experiencing is pretty annoying. I'm trying to optimize my first byte, by turning off compression, and gziping everything by webpack with CompressionPlugin. The issue is that it doesn't compress service-worker.js produced by sw-precache-webpack-plugin.

I understand the reason why: service-worker.js should cache all chunks produced by webpack after CompressionPlugin compression.

This is why I think it should be an option in sw-precache-webpack-plugin itself.

Thank you)

Research direction
The issue requests an option to GZIP the generated service worker.js file. Investigate the plugin's source code (likely in the repository's GitHub) to understand how it generates the service worker and how other assets are compressed. Look for existing compression options or hooks. Review comments for any suggested approaches. Consider modifying the plugin to accept a gzip option that compresses the service worker after generation, similar to webpack's CompressionPlugin.
