Trying to add vue (and SFCs) to my webpack app. The <template> and <script> blocks work fine, but for some reason the styles in the <style> block are not being extracted for production build.
In the dev build, it's extracting the .vue <style> block to a separate css file (named for the entrypoint). Which is OK but I'd prefer they went into my main stylesheet.
But no matter what I try, I can't get any .vue styles to show up (in any file) for the production build.
This is an abbreviated version of my webpack config:
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const VueLoaderPlugin = require("vue-loader/lib/plugin");
...
module.exports = (env) => {
return {
entry: {
app: ["./src/polyfills.js", "./src/scss/styles.scss", "./src/app.js"],
...
testview: "./src/js/views/TestView.js"
},
output: {
path: assets,
filename: "[name].[hash].js",
publicPath: "/static/"
},
resolve: {
modules: ["node_modules", "src"],

vue$: "vue/dist/vue.esm.js"

The .vue file I'm using is this demo one. I'm trying to import it into the entrypoint called 'testview' which contains simply:
import Vue from "vue";
import MainContent from "../components/main-content";
let MainComponent = Vue.extend(MainContent);
new MainComponent().$mount("#mainContent");
