[2.0.5] CSS Modules hash mismatch (React SSR)

[chrisblossom]

I have a React SSR that uses Webpack on the client and server. After updating to postcss-loader v2.0.3, my generated CSS Module hash's are different on the client and the server.

I am unsure if the issue is related to postcss-loader directly or if it is a new/updated dependency brought in by v2.0.3.

I can bring up a skeleton repository if that would help to demonstrate the issue I am having.

@chrisblossom Yep please provide a small repo, are you using sourcemaps in postcss-loader ?
Note that we are in the transition phase to move CSS Modules from css-loader into postcss-loader via a compatible PostCSS Plugin in the future

During the process of gutting my app to give an example repository, I found the following in my server webpack config:

        new webpack.LoaderOptionsPlugin({
            options: {
                context: __dirname,
            },
        }),

After removing that, everything works as expected. Thanks for the quick reply!
