我在我的angular 7开发配置中使用webpack。我正在使用webpack 3.x 我想将所有css迁移到scss。

这是我的webpack.config.common.js:

var webpack = require('webpack');

module.exports = {
    entry: {
        'app': './assets/app/main.ts'
    },

    resolve: {
        extensions: ['.js', '.ts']
    },

    module: {
        rules: [
            {
                test: /\.html$/,
                use: [{ loader: 'html-loader' }]
            },
            {
                test: /\.css$/, 
                use: [{ loader: 'raw-loader' }]
            },
            {
                test: /\.scss$/,
                use: [{
                    loader: "style-loader" 
                }, {
                    loader: "css-loader" 
                }, {
                    loader: "sass-loader" 
                }]
            },
            {
                test: /\.(png|jpe?g|gif|svg|woff|woff2|tff|eot|ico)$/,
                use: [{ loader: 'file-loader?name=assets/[name].[hash].[ext]' }]
            }
        ],
    exprContextCritical: false
    }
};

webpack.config.dev.js:

var path = require('path');

var webpackMerge = require('webpack-merge');
var commonConfig = require('./webpack.config.common.js');

module.exports = webpackMerge(commonConfig, {
    devtool: 'cheap-module-eval-source-map',

    output: {
        path: path.resolve(__dirname + '/public/js/app'),
        publicPath: "/js/app/",
        filename: 'bundle.js',
        chunkFilename: '[id].chunk.js'
    },
    module: {
        rules: [
            {
                test: /\.ts$/,
                use: [
                    {loader: 'awesome-typescript-loader', options: {
                        transpileOnly: true
                    }},
                    {loader: 'angular2-template-loader'},
                    {loader: 'angular-router-loader'}
                ]
            }
        ]

    }
});

webpack.config.prod.js:

const AngularCompilerPlugin = require('@ngtools/webpack').AngularCompilerPlugin;

var path = require('path');

var webpack = require('webpack');
var webpackMerge = require('webpack-merge');
var commonConfig = require('./webpack.config.common.js');

module.exports = webpackMerge.smart(commonConfig, {
    entry: {
        'app': './assets/app/main.aot.ts'
    },

    output: {
        path: path.join(__dirname + '/public/js/app'),
        filename: 'bundle.js',
        publicPath: '/js/app/',
        chunkFilename: '[id].[hash].chunk.js'
    },

    module: {
        rules: [
            {
                test: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/,
                loader: '@ngtools/webpack'
            },
            {
                test: /\.ts$/,
                use: [
                    'awesome-typescript-loader',
                    'angular2-template-loader',
                    'angular-router-loader?aot=true'
                ]
            }
        ]
    },

    plugins: [
        new webpack.optimize.UglifyJsPlugin({
            sourceMap: false
        }),
        new AngularCompilerPlugin({
            tsConfigPath: './tsconfig.json',
            entryModule: './assets/app/app.module#AppModule',
            sourceMap: true
        })
    ]
});

从package.json构建脚本:

“脚本”:{

    "start": "node ./bin/www",
    "build": "del-cli public/js/app && webpack --config webpack.config.dev.js --progress --profile --watch",
    "build:prod": "del-cli public/js/app && ngc -p tsconfig.aot.json && ngc -p tsconfig.aot.json && webpack --config webpack.config.prod.js --progress --profile --bail && del-cli 'public/js/app/**/*.js' 'public/js/app/**/*.js.map' '!public/js/app/bundle.js' '!public/js/app/*.chunk.js' 'assets/app/**/*.*.ngfactory.ts' 'assets/app/**/*.shim.ts' 'assets/app/**/*.ngsummary.json' 'assets/app/**/*.ngstyle.ts'",
  },

我尝试了在角度标签中不使用'styleUrls'的解决方案。我只有一个大的CSS文件 对于整个应用 如何使用Webpack从使用CSS迁移到CSS?

您总是可以混合使用全局scss和组件scss

但是,如果您还想拥有全局样式,则可以这样做:

在/ src / styles /文件夹中创建一个styles.scss

从您的app.module.ts(项目的根模块)中,仅以如下方式导入scss文件(显然选择正确的路径):

import '../styles/styles.scss';

现在,您可以使用styles.scss导入将在全局范围内应用于您项目的其他scs(或css)文件。

作为一个例子,这就是我在styles.scss中的项目中的内容:

@import '_bootstrap_settings.scss';
@import "~bootstrap/scss/bootstrap";
@import '~c3/c3';

// Angular Material Theme
@import "~@angular/material/prebuilt-themes/indigo-pink";

@import 'variables';
