Why webpack doesn't render CSS from components to vendor.css file? - html

Question

I use this template It works well. As you can see on the screen, all lybrarys (like bootstrap) render their CSS into vendor.css, but my component renders it into html directly, just into the header part in the html file in tag. Can you tell me how to configure it right?
// webpack.config.js
var isDevBuild = process.argv.indexOf('--env.prod') < 0;
var path = require('path');
var webpack = require('webpack');
var nodeExternals = require('webpack-node-externals');

var allFilenamesExceptJavaScript = /\.(?!js(\?|$))([^.]+(\?|$))/;
//var ExtractTextPlugin = require('extract-text-webpack-plugin');
// Configuration in common to both client-side and server-side bundles
var sharedConfig = {
resolve: { extensions: ['', '.js', '.ts'] },
output: {

publicPath: '/dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
},

}
};
// Configuration for client-side bundle suitable for running in browsers
var clientBundleConfig = merge(sharedConfig, {

Answer 1

It seems like you are using style-loader to load your component css. You can change it to be the same loader (most likely file-loader) as the vendor.css in your webpack.config

Answer 2

If you compare the two css loaders in your config files, you can see that webpack.config.vendor.js has this line:
{ test: /\.css(\?|$)/, loader: extractCSS.extract(['css']) }
under loaders. That is the line that takes the CSS and puts it in its own file. So if you change the CSS loader for your webpack.config.js and make sure to add:
var extractCSS = new ExtractTextPlugin('styles.css'); // or name it whatever you want
at the top of the file. It should work.
