• Operating System: MacOS
• Node Version: 10.15.3
• NPM Version: 6.4.1
• webpack Version: 4.39.1
• css-loader Version: 3.1.0

Expected Behavior

In 2.1.0 using this pattern for localIdentName: [name]_[local]_[hash:base64:5] the name portion would be transformed from file.module to file-module. File name is file.module.scss.

Actual Behavior

The . in file.module is no longer changed to a -.

We use babel-plugin-react-css-modules alongside css-loader. The babel plugin still transforms filenames in the same way the CSS Loader 2.* did.

Code

// CSS Loader portion of webpack config
{
  loader: 'css-loader',
  options: {
    modules: {
      localIdentName: '[name]_[local]_[hash:base64:5]',
    },
    importLoaders: 2,
    sourceMap: !production,
  },
},

How Do We Reproduce?

Use a SCSS filename with one or more . in the filename.
