Please Explain in Detail...
There is a now-abandoned project known as image-webpack-loader . The documentation for that says to use image-minimizer-webpack-plugin as a replacement. I haven't see a migration guide for this replacement process though. I only see a (very welcome) guide for starting from scratch.
Your Proposal for Changes
I think there should be a section for the project's readme.md file which explains how to smoothly convert from image-webpack-loader to image-minimizer-webpack-plugin , in addition to the already present guide for starting from scratch.
