[英]Spa template .net core 2.0 angular 4 webpack 2 use sass not boostrap 4 css
我是webpack的新手,我从未使用它。 我使用spa模板(.net core 2.0 + angular 4)创建了一个应用程序,它使用boostrap.css并生成vendor.css。 我想使用bootstrap.scss并生成vendor.scss。
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 ? [] : [

new AotPlugin({
tsConfigPath: './tsconfig.json',
entryModule: path.join(__dirname, 'ClientApp/app/app.module.server#AppModule'),

})
]),
output: {
libraryTarget: 'commonjs',
path: path.join(__dirname, './ClientApp/dist')
},
target: 'node',
devtool: 'inline-source-map'
});
return [clientBundleConfig, serverBundleConfig];
};
和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 = [

];
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({ $: 'jquery', jQuery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable)
new webpack.ContextReplacementPlugin(/\@angular\b.*\b(bundles|linker)/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/11580
new webpack.ContextReplacementPlugin(/angular(\\|\/)core(\\|\/)@angular/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/14898
new webpack.IgnorePlugin(/^vertx$/) // Workaround for https://github.com/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({

new webpack.optimize.UglifyJsPlugin()

});
const serverBundleConfig = merge(sharedConfig, {

output: {

});
return [clientBundleConfig, serverBundleConfig];
}
我不知道webpack.config和webpack.config.vendor之间的区别是什么,但我从这行'bootstrap / dist / css / bootstrap.css'修改了webpack.config.wendor到这行'bootstrap / scss / bootstrap .scss',我放了一个sass loader但是它没有用。 我安装了一个出现在package.json中的sass加载器。
"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"
我想我应该用sass loader添加一个新规则,但我不知道如何编写它以及放置它(config或config.vendor)。 你能帮我吗?
我有同样的问题。
对我来说,它在“webpack.config.js”中进行了以下调整:
{
test: /\.scss$/,
loaders: ['to-string-loader', 'css-loader', 'sass-loader']
},
这是整个配置(或多或少是默认配置):
const sharedConfig = {
stats: {modules: false},
context: __dirname,
resolve: {extensions: ['.js', '.ts']},
output: {
filename: '[name].js',
publicPath: 'dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
},
module: {
rules: [
{
test: /\.ts$/,
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()]
};
尝试修改模块规则并为.scss添加以下测试
module: {
rules: [
{
test: /\.scss$/, use: [{
loader: "style-loader" // creates style nodes from JS strings
}, {
loader: "css-loader" // translates CSS into CommonJS
}, {
loader: "sass-loader" // compiles Sass to CSS
}]
},
{ test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, use: 'url-loader?limit=100000' }
]
}
