Spa模板.NET Core 2.0 angular 4 webpack 2使用sass not boostrap 4 CSS

本文介绍了Spa模板.NET Core 2.0 angular 4 webpack 2使用sass not boostrap 4 CSS的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我是webpack的新手，但我从未使用过它. 我使用spa模板( 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 ( core 2.0 + angular 4) that uses boostrap.css and make vendor.css. I want to use bootstrap.scss and make vendor.scss.

webpack.config.js

webpack.config.js

const path = require('path'); const webpack = require('webpack'); const merge = require('webpack-merge'); const AotPlugin = require('@ngtools/webpack').AotPlugin; const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin; module.exports = (env) => { // Configuration in common to both client-side and server-side bundles const isDevBuild = !(env && env.prod); 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' } ] }, plugins: [new CheckerPlugin()] }; // Configuration for client-side bundle suitable for running in browsers const clientBundleOutputDir = './wwwroot/dist'; const clientBundleConfig = merge(sharedConfig, { entry: { 'main-client': './ClientApp/boot.browser.ts' }, output: { path: path.join(__dirname, clientBundleOutputDir) }, plugins: [ new webpack.DllReferencePlugin({ context: __dirname, manifest: require('./wwwroot/dist/vendor-manifest.json') }) ].concat(isDevBuild ? [ // Plugins that apply in development builds only new webpack.SourceMapDevToolPlugin({ filename: '[file].map', // Remove this line if you prefer inline source maps moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk }) ] : [ // Plugins that apply in production builds only new webpack.optimize.UglifyJsPlugin(), new AotPlugin({ tsConfigPath: './tsconfig.json', entryModule: path.join(__dirname, 'ClientApp/app/app.module.browser#AppModule'), exclude: ['./**/*.server.ts'] }) ]) }); // Configuration for server-side (prerendering) bundle suitable for running in Node const serverBundleConfig = merge(sharedConfig, { resolve: { mainFields: ['main'] }, entry: { 'main-server': './ClientApp/boot.server.ts' }, plugins: [ new webpack.DllReferencePlugin({ context: __dirname, manifest: require('./ClientApp/dist/vendor-manifest.json'), sourceType: 'commonjs2', name: './vendor' }) ].concat(isDevBuild ? [] : [ // Plugins that apply in production builds only new AotPlugin({ tsConfigPath: './tsconfig.json', entryModule: path.join(__dirname, 'ClientApp/app/app.module.server#AppModule'), exclude: ['./**/*.browser.ts'] }) ]), output: { libraryTarget: 'commonjs', path: path.join(__dirname, './ClientApp/dist') }, target: 'node', devtool: 'inline-source-map' }); return [clientBundleConfig, serverBundleConfig]; };

和webpack.config.vendor.js

And webpack.config.vendor.js

const path = require('path'); const webpack = require('webpack'); const ExtractTextPlugin = require('extract-text-webpack-plugin'); const merge = require('webpack-merge'); const treeShakableModules = [ '@angular/animations', '@angular/common', '@angular/compiler', '@angular/core', '@angular/forms', '@angular/http', '@angular/platform-browser', '@angular/platform-browser-dynamic', '@angular/router', 'zone.js', ]; const nonTreeShakableModules = [ 'bootstrap', 'bootstrap/dist/css/bootstrap.css', 'es6-promise', 'es6-shim', 'event-source-polyfill', 'jquery', ]; const allModules = treeShakableModules.concat(nonTreeShakableModules); module.exports = (env) => { const extractCSS = new ExtractTextPlugin('vendor.css'); const isDevBuild = !(env && env.prod); const sharedConfig = { stats: { modules: false }, resolve: { extensions: [ '.js' ] }, module: { rules: [ { test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, use: 'url-loader?limit=100000' } ] }, output: { publicPath: 'dist/', filename: '[name].js', library: '[name]_[hash]' }, plugins: [ new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable) new webpack.ContextReplacementPlugin(/\@angular\b.*\b(bundles|linker)/, path.join(__dirname, './ClientApp')), // Workaround for github/angular/angular/issues/11580 new webpack.ContextReplacementPlugin(/angular(\\|\/)core(\\|\/)@angular/, path.join(__dirname, './ClientApp')), // Workaround for github/angular/angular/issues/14898 new webpack.IgnorePlugin(/^vertx$/) // Workaround for github/stefanpenner/es6-promise/issues/100 ] }; const clientBundleConfig = merge(sharedConfig, { entry: { // To keep development builds fast, include all vendor dependencies in the vendor bundle. // But for production builds, leave the tree-shakable ones out so the AOT compiler can produce a smaller bundle. vendor: isDevBuild ? allModules : nonTreeShakableModules }, output: { path: path.join(__dirname, 'wwwroot', 'dist') }, module: { rules: [ { test: /\.css(\?|$)/, use: extractCSS.extract({ use: isDevBuild ? 'css-loader' : 'css-loader?minimize' }) } ] }, plugins: [ extractCSS, new webpack.DllPlugin({ path: path.join(__dirname, 'wwwroot', 'dist', '[name]-manifest.json'), name: '[name]_[hash]' }) ].concat(isDevBuild ? [] : [ new webpack.optimize.UglifyJsPlugin() ]) }); const serverBundleConfig = merge(sharedConfig, { target: 'node', resolve: { mainFields: ['main'] }, entry: { vendor: allModules.concat(['aspnet-prerendering']) }, output: { path: path.join(__dirname, 'ClientApp', 'dist'), libraryTarget: 'commonjs2', }, module: { rules: [ { test: /\.css(\?|$)/, use: ['to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] } ] }, plugins: [ new webpack.DllPlugin({ path: path.join(__dirname, 'ClientApp', 'dist', '[name]-manifest.json'), name: '[name]_[hash]' }) ] }); return [clientBundleConfig, serverBundleConfig]; }

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()] };
