手动完成以下配置，以支持标题中给出的所有技术（webpack，typescript，phaser和angular）。

它适用于角度组件样式表。但看起来包含全球样式表似乎是不可能的。以下是相关的配置文件：

HTML文件：

<!-- src/index.html -->
<!DOCTYPE html>
<html>
  <head>
    <base href="/">
    <meta charset="UTF-8">
    <!-- it's included here! -->
    <link rel="stylesheet" href="styles/main.css">
    <meta name="viewport" content="width=device-width, initial-scale=1">
  </head>
  <body>
    <app-root></app-root>
  </body>
</html>

CSS文件：

/*
src/styles/main.css
This file is correctly loaded in dev environment. When I build the project it disapear. :(
*/
body {
    background: #253050 url('../assets/design/main_background.jpg') no-repeat center;
}

和webpack配置：

// config/webpack.common.js
'use strict';

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
const CleanWebpackPlugin = require('clean-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
const path = require('path');
var helpers = require('./helpers');

var distDir = path.resolve(__dirname, '../dist');

// Phaser webpack config
const phaserModule = path.join(__dirname, '/../node_modules/phaser-ce/');
const phaser = path.join(phaserModule, 'build/custom/phaser-split.js');
const pixi = path.join(phaserModule, 'build/custom/pixi.js');
const p2 = path.join(phaserModule, 'build/custom/p2.js');

module.exports = {
    entry: {
        'polyfills': './src/polyfills.ts',
        "app": "./src/main.ts"
    },

    // What files webpack will manage
    resolve: {
        extensions: ['.js', '.ts', '.tsx'],
        alias: {
            'phaser': phaser,
            'pixi': pixi,
            'p2': p2
        }
    },
    output: {
        path: distDir,
        filename: '[name]_bundle.js'
    },

    module: {
        rules: [
            { test: /assets(\/|\\)/, use: [ 'file-loader' ] },
            {
                test: /\.tsx?$/,
                // ts-loader loads typescript files
                // angular2-template-loader is needed to load component templates
                loaders: ['ts-loader', 'angular2-template-loader'],
                exclude: [
                    /.+phaser-ce\/typescript\/.+\.ts$/,
                    /typescript\/.+\.d\.ts$/
                ]
            },
            {
              test: /\.html$/,
              loader: 'html-loader'
            },

            // to-string-loader is for css loaded by angular components
            // .... and loading angular css work as expected.
            { test: /\.css$/, loaders: ['to-string-loader', 'css-loader'] },
            {
              test: /\.scss$/, // I'd like so much sass work but guess what... it doesn't!
              use: ['to-string-loader', 'css-loader', 'sass-loader']
            },

            // Because phaser and its dependencies are not made for TypeScript and webpack
            { test: /pixi\.js/, use: [{loader: 'expose-loader', options: 'PIXI'}] },
            { test: /phaser-split\.js$/, use: [{loader: 'expose-loader', options: 'Phaser'}] },
            { test: /p2\.js/, use: [{loader: 'expose-loader', options: 'p2'}] }
        ]
    },

    plugins: [
        new webpack.ContextReplacementPlugin(
            // The (\\|\/) piece accounts for path separators in *nix and Windows

            // For Angular 5, see also https://github.com/angular/angular/issues/20357#issuecomment-343683491
            /\@angular(\\|\/)core(\\|\/)esm5/,
            helpers.root('src'), // location of your src
            {
              // your Angular Async Route paths relative to this root directory
            }
          ),
        new CleanWebpackPlugin([distDir]),
        new HtmlWebpackPlugin({
            template: 'src/index.html',
            chunksSortMode: function(a, b) {
                // set the load order !
                var order = ["polyfills", "app"];
                return order.indexOf(a.names[0]) - order.indexOf(b.names[0]);
            }
        })
    ]
};

这是webpack.prod.js配置：

module.exports = merge(common, {
    devtool: 'source-map',
    plugins: [
        // stops the build if there is an error
        new webpack.NoEmitOnErrorsPlugin(),
        new UglifyJSPlugin({sourceMap: true}),
        // extracts embedded css as external files, adding cache-busting hash to the filename
        new ExtractTextPlugin('[name].[hash].css'),
        new webpack.DefinePlugin({
            'process.env.NODE_ENV': JSON.stringify('production')
        })
    ]
});

当我运行webpack --config config/webpack.prod.js全局CSS未加载时，没有错误。只是没有CSS。

随意解释如何加载SCSS，因为它对我来说即使在开发模式下也不起作用。

谢谢！

Answer 1

我终于成功了。所以这是我所做的改变：

1）现在在css / scss子句中忽略了style.css的路径。

{
  exclude: path.resolve(__dirname, '../src/styles'),
  test: /\.css$/, loaders: ['to-string-loader', 'css-loader']
},
{
  exclude: path.resolve(__dirname, '../src/styles'),
  test: /\.scss$/,
  use: ['to-string-loader', 'css-loader', 'sass-loader']
}

2）我为CSS添加了一个新的条目文件

entry: {
  'polyfills': './src/polyfills.ts',
  'app': './src/main.ts',
  'css': './src/styles/main.css'
}

3）它的工作原理是因为我还配置了一个使用ExtractTextPlugin

的新规则

{
  test: /\.css$/,
  exclude: path.resolve(__dirname, '../src/app'),
  use: ExtractTextPlugin.extract({
    fallback: 'style-loader',
    use: 'css-loader'
  })
}

请注意，这也是因为prod配置将new ExtractTextPlugin('[name].[hash].css')指定为插件。（这意味着您需要在通用配置中添加它以避免在开发环境中出现任何错误）

我认为您需要使用angular-cli，您可以在angular-cli.JSON中设置自定义css网址，如下所示：

"styles": [
        "../node_modules/bootstrap/dist/css/bootstrap.min.css",
        "../node_modules/font-awesome/css/font-awesome.min.css"

      ],

Answer 3

可以在.angular-cli.json中设置更多全局样式，它可能看起来像这样：

...
"apps": [
    {
      ...

      "styles": [
          "app/core/preloader/preloader.scss",
          "styles.scss"
      ],
      ...
    }
]
...

在app部分中，您应该会发现可以在此处设置更多全局资源/脚本。
