missing possibility to apply modifyUrlPrefix or manifestTransforms to all automatically added assets as well

[antony-k1208]

Library Affected:
workbox-webpack-plugin

Browser & Platform:
all platforms

Issue or Feature Request Description:
We are currently stumbling upon a problem with this automatic generation of a precache manifest that contains URLs for assets created by the current webpack compilation. This is all fine, but the entries urls are totally unusable for our setup. It seems workbox-webpack-plugin is using webpacks output.path setting followed by other options made inside our webpack.config.

What we get is something like this:

{
    "revision": "51b9703cbbf90b6ca05a1b58e4e85051",
    "url": "../fonts/daxot-condbold-webfont.ttf"
  }

What we need is a possibility to apply something like the provided options modifyUrlPrefix or manifestTransforms which will also be applied to this automatic generation as well and not only to additional assets in order to get something like this:

{
    "revision": "51b9703cbbf90b6ca05a1b58e4e85051",
    "url": "ui/theme/fonts/daxot-condbold-webfont.ttf"
  }

With gulp and workbox-build we were able by using globDirectory, globPatterns and manifestTransforms to achieve exactly that behaviour.

Any help would be gladly appreciated.

Regards,
Antony

Thanks, Antony.

That's planned for the next major release of workbox-webpack-plugin, and tracked in #1227
