Webpack-如何在prod / qa / dev环境中包含生成的CSS?

标签: css webpack

我已将 .scss 样式添加到我的网站。 .scss文件位于其.jsx组件旁边。

我这样引用.jsx中的样式:

import styles from './guest-card.component.scss'
...
<Card className={styles.card}>

运行本地服务器webpack-dev-server --inline --progress --config build/webpack.cold.conf.js

时,一切看起来都很不错

在构建用于分发应用程序(例如开发机或质量检查机)时,我运行npm run build。这将构建一个dist文件夹,其中包含所有已编译的内容。

当我在开发/质量保证服务器上查看网站时,我的样式丢失了。

在dist文件夹中,我看到一个/static/css/app.css及其编译样式。大!样式看起来正确。

我的问题:如何在生产站点中包含这些/static/css/app.css?我尝试添加一个<link rel="stylesheet" ...并将其包含在内,但我肯定会这样做工作,但会在我的本地计算机上显示404。

构建样式的正确方法是什么

所以我的问题是: 我的问题是-我如何让我的应用程序引用这个新的app.css?如果我添加

build.js

'use strict';
require('./check-versions')();

process.env.NODE_ENV = 'production';

const ora = require('ora');
const rm = require('rimraf');
const path = require('path');
const chalk = require('chalk');
const webpack = require('webpack');
const config = require('../config');
const webpackConfig = require('./webpack.prod.conf');

const spinner = ora('building...');
spinner.start();

rm(path.join(config.build.assetsRoot, config.build.assetsSubDirectory), err => {
  if (err) throw err;
  webpack(webpackConfig, function (err, stats) {
    spinner.stop();
    if (err) throw err;
    process.stdout.write(stats.toString({
      colors: true,
      modules: false,
      children: false,
      chunks: false,
      chunkModules: false
    }) + '\n\n');

    if (stats.hasErrors()) {
      console.log(chalk.red('  Build failed with errors.\n'));
      process.exit(1)
    }

    console.log(chalk.cyan('  Build complete.\n'));
    console.log(chalk.yellow(
      '  Tip: built files are meant to be served over an HTTP server.\n' +
      '  Opening index.html over file:// won\'t work.\n'
    ))
  })

如果您错过了index.html中生成的样式文件的链接,则应在此处搜索问题,因为此插件对此负责

new HtmlWebpackPlugin({
      filename: process.env.NODE_ENV === 'testing'
        ? 'index.html'
        : config.build.index,
      host: '@_host_@',
      template: 'index.html',
      inject: false,
      minify: {
        removeComments: true,
        collapseWhitespace: true,
        removeAttributeQuotes: true
        // more options:
        // https://github.com/kangax/html-minifier#options-quick-reference
      }

我刚刚浏览了插件文档,可能您需要删除inject:false。默认值为true,会将您的资产放入index.html
