在以前的项目中,我使用angular-cli来构建我的项目。现在我必须在.NET项目中直接使用webpack。而且我正在努力让一件简单的事情发挥作用:
我的构建输出目录是wwwroot / dist(我们的项目要求)。
Angular-cli有一个很好的简化"配置:
"outDir": "../wwwroot/dist",
"assets": [
"assets"
],
"styles": [
"styles.css"
],
然后我用一个正确的dist文件夹结束,我的资产移动到正确的输出目录,我的应用程序级别的styles.css在我的应用程序的任何地方都可用。
现在,我无法管理如何配置webpack以在新项目结构和配置中实现此功能。我认为我的团队使用VS2015模板启动了项目,该模板生成了一个通用结构:https://github.com/aspnet/JavaScriptServices/tree/dev/templates/Angular2Spa
webpack.config.js
var isDevBuild = process.argv.indexOf('--env.prod') < 0;
var path = require('path');
var webpack = require('webpack');
var nodeExternals = require('webpack-node-externals');
var merge = require('webpack-merge');
var allFilenamesExceptJavaScript = /\.(?!js(\?|$))([^.]+(\?|$))/;
// Configuration in common to both client-side and server-side bundles
var sharedConfig = {
resolve: { extensions: [ '', '.js', '.ts' ] },
output: {
filename: '[name].js',
publicPath: '/dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
},
module: {
loaders: [
{ test: /\.ts$/, include: /ClientApp/, loader: 'ts', query: { silent: true } },
{ test: /\.html$/, loader: 'raw' },
{ test: /\.css$/, loader: 'to-string!css' },
{ test: /\.(png|jpg|jpeg|gif|svg)$/, loader: 'url', query: { limit: 25000 } }
]
}
};
// Configuration for client-side bundle suitable for running in browsers
var clientBundleConfig = merge(sharedConfig, {
entry: { 'main-client': './ClientApp/boot-client.ts' },
output: { path: path.join(__dirname, './wwwroot/dist') },
devtool: isDevBuild ? 'inline-source-map' : null,
plugins: [
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./wwwroot/dist/vendor-manifest.json')
})
].concat(isDevBuild ? [] : [
// Plugins that apply in production builds only
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.optimize.UglifyJsPlugin()
])
});
// Configuration for server-side (prerendering) bundle suitable for running in Node
var serverBundleConfig = merge(sharedConfig, {
entry: { 'main-server': './ClientApp/boot-server.ts' },
output: {
libraryTarget: 'commonjs',
path: path.join(__dirname, './ClientApp/dist')
},
target: 'node',
devtool: 'inline-source-map',
externals: [nodeExternals({ whitelist: [allFilenamesExceptJavaScript] })] // Don't bundle .js files from node_modules
});
module.exports = [clientBundleConfig, serverBundleConfig];
还有一个供应商配置可以单独构建供应商并更少地刷新它们。我不希望我的资产和全局style.css成为供应商的一部分。
webpack.config.vendor.js
var isDevBuild = process.argv.indexOf('--env.prod') < 0;
var path = require('path');
var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var extractCSS = new ExtractTextPlugin('vendor.css');
module.exports = {
resolve: {
extensions: [ '', '.js' ]
},
module: {
loaders: [
{ test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, loader: 'url-loader?limit=100000' },
{ test: /\.css(\?|$)/, loader: extractCSS.extract(['css']) }
]
},
entry: {
vendor: [
'@angular/common',
'@angular/compiler',
'@angular/core',
'@angular/http',
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/router',
'@angular/platform-server',
'angular2-universal',
'angular2-universal-polyfills',
'bootstrap',
'bootstrap/dist/css/bootstrap.css',
'bootstrap-filestyle',
'font-awesome/css/font-awesome.css',
'es6-shim',
'es6-promise',
'jquery',
'zone.js',
]
},
output: {
path: path.join(__dirname, 'wwwroot', 'dist'),
filename: '[name].js',
library: '[name]_[hash]',
},
plugins: [
extractCSS,
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable)
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.DllPlugin({
path: path.join(__dirname, 'wwwroot', 'dist', '[name]-manifest.json'),
name: '[name]_[hash]'
})
].concat(isDevBuild ? [] : [
new webpack.optimize.UglifyJsPlugin({ compress: { warnings: false } })
])
};
我希望能够使用styles.css应用程序范围中定义的css,并将我的资产移到wwwroot / dist中。我想通过加载/ dist / assets / xxx
在我的应用中访问它们答案 0 :(得分:2)
正在浏览一些Webpack问题并发现了这一点。尽管它确实很旧,并且您可能找到了解决方法,但我仍然想提出一个解决方案。
Webpack将加载程序用于各种类型的文件,这些文件在代码中需要/导入。 看到您已经为css和图像指定了加载程序,我猜测您没有直接在JavaScript代码中要求/导入上述任何资产,而只是在css或html中引用它们。
在这种情况下,您可以使用copy-webpack-plugin之类的webpack插件将这些资产复制到构建目录中。 会是这样的:
//webpack.config.js
var CopyWebpackPlugin = require('copy-webpack-plugin');
...
config.plugins = config.plugins.concat([
new CopyWebpackPlugin([
{ from: 'assets', to: '../wwwroot/dist/assets' }
]),
...
]);
