css - 无法使用 Webpack 3 正确加载 sass 和 font-awesome

Question

目前，我正在尝试使用 Webpack3 加载我的 scss 文件和 Font Awesome 。

这是我的 webpack.config.js

const autoprefixer = require('autoprefixer');
const path = require('path');
const webpack = require('webpack');
const precss = require('precss');
const ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    entry: [
        './Scripts/app.ts',
        './Scripts/scss/main.scss',
        //'font-awesome/scss/font-awesome.scss',
        'tether'
    ],
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, './Scripts/dist')
    },
    module: {
        rules: [
            {
                loader: 'ts-loader',
                test: /\.ts$/,
                exclude: /node_modules/
            },
            {
                test: /\.css$/,
                use: [
                    'style-loader',
                    'css-loader',
                    'postcss-loader'
                ]
            },
            {
                test: /\.woff2?(\?v=[0-9]\.[0-9]\.[0-9])?$/,
                use: 'url-loader?limit=10000'
            },
            {
                test: /\.(ttf|eot|svg)(\?[\s\S]+)?$/,
                use: 'file-loader'
            },
            {
                test: /\.(jpe?g|png|gif|svg)$/i,
                use: [
                    'file-loader?name=images/[name].[ext]',
                    'image-webpack-loader?bypassOnDebug'
                ]
            },
            // font-awesome
            {
                test: /font-awesome\.config\.js/,
                use: [
                    { loader: 'style-loader' },
                    { loader: 'font-awesome-loader' }
                ]
            },
            // Bootstrap 4
            {
                test: /bootstrap\/dist\/js\/umd\//,
                use: 'imports-loader?jQuery=jquery'
            },
            // SCSS pre-processing
            {
                test: /\.(scss)$/,
                //use: ExtractTextPlugin.extract({
                //    fallback: 'style-loader',
                //    use: [
                //        // the order of the loaders cannot be changed
                //        {
                //            loader: 'css-loader',
                //            options: { minimize: false } // minifize css file
                //        }, // translates CSS into CommonJS modules
                //        {
                //            loader: 'postcss-loader', // Run post css actions
                //            options: {
                //                // post css plugins, can be exported to postcss.config.js
                //                plugins() {
                //                    return [precss, autoprefixer];
                //                }
                //            }
                //        },
                //        { loader: 'sass-loader' } // compiles SASS to CSS
                //    ]
                //})

                use: [{
                    loader: 'style-loader' // creates style nodes from JS strings
                }, {
                    loader: 'css-loader' // translates CSS into CommonJS
                }, {
                    loader: 'sass-loader' // compiles Sass to CSS
                }]
            }
        ]
    },
    resolve: {
        extensions: ['.ts', '.js']
    },
    plugins: [
        new ExtractTextPlugin('main.css', {
            allChunks: true
        }),
        // minify the bundled js files
        new webpack.optimize.UglifyJsPlugin({
            include: /\.js$/,
            minimize: true,
            sourceMap: true
        }),
        new webpack.ProvidePlugin({
            jQuery: 'jquery',
            jquery: 'jquery',
            $: 'jquery',
            tether: 'tether',
            Tether: 'tether',
            Popper: ['popper.js', 'default'],
            Alert: 'exports-loader?Alert!bootstrap/js/dist/alert',
            Button: 'exports-loader?Button!bootstrap/js/dist/button',
            Carousel: 'exports-loader?Carousel!bootstrap/js/dist/carousel',
            Collapse: 'exports-loader?Collapse!bootstrap/js/dist/collapse',
            Dropdown: 'exports-loader?Dropdown!bootstrap/js/dist/dropdown',
            Modal: 'exports-loader?Modal!bootstrap/js/dist/modal',
            Popover: 'exports-loader?Popover!bootstrap/js/dist/popover',
            Scrollspy: 'exports-loader?Scrollspy!bootstrap/js/dist/scrollspy',
            Tab: 'exports-loader?Tab!bootstrap/js/dist/tab',
            Tooltip: "exports-loader?Tooltip!bootstrap/js/dist/tooltip",
            Util: 'exports-loader?Util!bootstrap/js/dist/util'
        })
    ],
    devtool: 'source-map'
};

更多细节(基于 .scss 的规则):

1. 我使用以下方法在我的 main.scss 中导入字体超棒的 scss:

$fa-font-path: "~/node_modules/font-awesome/fonts";
@import '~font-awesome/scss/font-awesome.scss';

1. 字体和图标引用了“node_moduldes”中的包(这不是我在生产中想要的)

2. 构建工件只是 bundle.js

如果我运行 webpack，似乎一切正常。但是，一旦我们开始生产，我假设指向 node_module 的图标/字体链接将被破坏。

这是我的 scss:

如果我使用注释掉的代码，font-awesome 可以正确加载，但我的 scss 文件不能。

详情:

• 可以生成所有svg/ttf/eot文件
• scss 可以处理成 css 文件，但是当我加载页面时，它们看起来很糟糕。

我的问题:

有什么方法可以加载 font-awesome 和所有工件并使用 Webpack 3 正确加载我的 scss 组件(如生产)？

提前致谢。

Answer 1

我花了一些时间努力寻找更好的解决方案。这是我的方法，它按预期工作:

我引用了两个资源:

1. Using FontAwesome with Sass
2. sass 加载器:https://github.com/webpack-contrib/sass-loader

一些我想强调的事情:

• 我们如何“导入”包。我将 import css 文件从我的 TypeScript 文件移动到 main.scss。一切都像一个魅力。
• 另一个重要的事情是sass-loader有@import的规则

webpack provides an advanced mechanism to resolve files. The sass-loader uses node-sass' custom importer feature to pass all queries to the webpack resolving engine. Thus you can import your Sass modules from node_modules. Just prepend them with a ~ to tell webpack that this is not a relative import:

@import "~bootstrap/dist/css/bootstrap";

It's important to only prepend it with ~, because ~/ resolves to the home directory. webpack needs to distinguish between bootstrap and ~bootstrap because CSS and Sass files have no special syntax for importing relative files. Writing @import "file" is the same as @import "./file";

来自 https://github.com/webpack-contrib/sass-loader

所以这是我的 main.scss 文件:

@import '~bootstrap/dist/css/bootstrap.min.css';
@import '~inputmask/css/inputmask.css';

$fa-font-path: "~font-awesome/fonts";
@import '~font-awesome/scss/font-awesome.scss';

// import partials
@import "variables";
@import "mixins";

@import "accordion";
@import "buttons";
@import "cards";
@import "container";
@import "errors";
@import "fonts";
@import "form";
@import "headers";
@import "hyperlinks";
@import "tables";
@import "warnings";
@import "wcb-footer";
@import "wcb-header";

@import "asmt-report"; // optional
