我将 sass 文件（app.scss）作为导入引用（将其包含在 styleUrls 数组中时出现错误）
import { Component, ViewEncapsulation } from '@angular/core';
import '../../assets/css/app.scss';
@Component({
selector: 'appMain',
styleUrls: [
'../../../../node_modules/ng2-toastr/bundles/ng2-toastr.min.css',
],
encapsulation: ViewEncapsulation.None,
templateUrl: './app.main.component.html'
})
export class AppMainComponent {
}
将 webpack 与我当前的配置（包括使用 ExtractTextPlugin）一起使用，我生成的 app.css.map 文件基本上是空的。看起来像：
{"version":3,"sources":[],"names":[],"mappings":"","file":"app.css","sourceRoot":""}
我需要更改什么才能正确生成源映射文件？我的 webpack.config.js 文件如下所示：
const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const AotPlugin = require('@ngtools/webpack').AotPlugin;
const CopyWebpackPlugin = require('copy-webpack-plugin');
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;
const ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = (env) => {
// Configuration in common to both client-side and server-side bundles
const isDevBuild = !(env && env.prod);
const extractCSS = new ExtractTextPlugin('app.css');
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: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/, include: [/ClientApp/, /\$\$_gendir/], use: isDevBuild ? ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] : '@ngtools/webpack' },
{ test: /\.html$/, 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$(\?|$)/,
exclude: /node_modules/,
use: extractCSS.extract({
use: [{
loader: "to-string-loader"
}, {
loader: isDevBuild ? 'css-loader' : 'css-loader?minimize', options: {
sourceMap: true
}
}, {
loader: 'sass-loader', options: {
sourceMap: true
}
}] })
}
]
},
plugins: [
extractCSS,
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']
})
])
});
return [clientBundleConfig];
};
