Webpack 3 - ExtractTextPlugin - localIdentName not applied to component from node_modules

Question

Webpack 3 - ExtractTextPlugin - localIdentName not applied to component from node_modules

I have a Webpack 3 installation using ExtractTextPlugin

and localIdentName

not being applied to CSS classes generated from node_modules

, specifically from a package react-spinkit

.

I am using a component <Spinner />

from react-spinkit

which creates the following CSS class: You will see that the classes imported by the module do not explicitly use a hash localIdentName

to them.

ExtractTextPlugin

seems to generate the class names correctly as shown in my output file app.css

:

Webpack always makes me know how it works every time I use it. Here is my config file:

const path = require('path');
const webpack = require('webpack');
const { CheckerPlugin } = require('awesome-typescript-loader');
const ManifestPlugin = require('webpack-manifest-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

const config = {
  devtool: 'source-map',

  resolve: {
    extensions: ['.ts', '.tsx', '.js', '.jsx', '.css'],
    modules: ['node_modules', 'app'],
    alias: {
      Assets: path.resolve(__dirname, '../../src/assets')
    }
  },

  entry: {
    app: [
      'webpack-hot-middleware/client?reload=true',
      './src/client.tsx'
    ]
  },

  output: {
    path: path.resolve('./build/public'),
    publicPath: '/public/',
    filename: 'js/[name].js',
    pathinfo: true
  },
