What I did
I upgraded the
postcss-loader
dependency to v4.2.0, which allows users to configure their postcss plugins with apostcss.config.js
file. However, unlike previous attempts at updating postcss dependencies, I kept thepostcss
version at 7.0.35 by adding it as a peerDep ofpostcss-loader
(which is now required).This should supersede #8907 because the
postcss-loader
does the searching and also combines the config passed to the loader with the config file found.I also removed the
ident
option on the config becausepostcss-loader
release notes said it isn't needed anymore.
