Spa模板.NET Core 2.0 angular 4 webpack 2使用sass not boostrap 4 CSS [英] Spa template .net core 2.0 angular 4 webpack 2 use sass not boostrap 4 css

问题描述

我是webpack的新手，但我从未使用过它. 我使用spa模板(.net core 2.0 + angular 4)制作了一个应用程序，该应用程序使用boostrap.css并制作了vendor.css.我想使用bootstrap.scss并制作vendor.scss.

I'm new to webpack, and i never used it. I made an application with spa template (.net core 2.0 + angular 4) that uses boostrap.css and make vendor.css. I want to use bootstrap.scss and make vendor.scss.

我不知道webpack.config和webpack.config.vendor之间有什么区别，但是我从"bootstrap/dist/css/bootstrap.css"这一行修改了webpack.config.wendor，改为"bootstrap/scss/bootstrap.scss'，然后我放了一个sass加载程序，但是它不起作用. 我安装了出现在package.json中的sass加载器.

I don't know what's the difference betwen webpack.config and webpack.config.vendor but i modified webpack.config.wendor from this line 'bootstrap/dist/css/bootstrap.css', to this line 'bootstrap/scss/bootstrap.scss', and i put a sass loader but it doesn't working. I installed a sass loader that appears in package.json.

"node-sass": "^4.5.3",
"postcss-loader": "^2.0.6",
"resolve-url-loader": "^2.1.0",
"sass-loader": "^6.0.6",
"style-loader": "^0.18.2",
"url-loader": "^0.5.9"

我认为我应该使用一个sass加载器添加一个新规则，但是我不知道如何编写它以及在哪里放置它(config或config.vendor). 你能帮我吗?

I think i should add a new rule with a sass loader but i don't know how to write it and where to put it (config or config.vendor). Can you help me please?

推荐答案

我遇到了同样的问题.

I had the same problem.

对我来说，它在"webpack.config.js"中进行了以下调整:

For me it worked with the following adjustment in "webpack.config.js":

            {
                test: /\.scss$/,
                loaders: ['to-string-loader', 'css-loader', 'sass-loader']
            },

这是整个配置(或多或少是默认配置):

Here is the whole configuration (more or less the default config):

  const sharedConfig = {
        stats: {modules: false},
        context: __dirname,
        resolve: {extensions: ['.js', '.ts']},
        output: {
            filename: '[name].js',
            publicPath: 'dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
        },
        module: {
            rules: [
                {
                    test: /\.ts$/,
                    include: /ClientApp/,
                    use: isDevBuild ? ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] : '@ngtools/webpack'
                },
                {test: /\.html$/, use: 'html-loader?minimize=false'},
                {test: /\.css$/, use: ['to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize']},
                {test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=25000'},
                {
                    test: /\.scss$/,
                    loaders: ['to-string-loader', 'css-loader', 'sass-loader']
                },
            ]
        },
        plugins: [new CheckerPlugin()]
    };
