I think we somehow end up believing we are writing to a .js file. @daydayuphuan What is your complete webpack config (around CSS especially), as this appears to be some sort of bad interaction...

const extract = new ExtractTextPlugin({
    filename: (getPath) => {
        return getPath('style/[name].css').replace('js/', '');
    },
    allChunks: true
});

{
    test: /\.css$/,
    loader: extract.extract({
        fallback: 'style-loader',
        use: ['css-loader', 'postcss-loader']
    })
},
{
    test: /\.less$/,
    loader: extract.extract(['postcss-loader', 'less-loader'])
}
