我试图得到css要求在webpack使用ExtractTextPlugin工作，但没有成功
@H_301_2@我想要一个单独的CSS文件，而不是内联任何CSS。
@H_301_2@这里是我的webpack配置：
var path = require('path');
var webpack = require('webpack');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
devtool: 'eval',entry: [
'webpack-dev-server/client?http://localhost:3000','webpack/hot/only-dev-server','./scripts/index'
],output: {
path: path.join(__dirname,'build'),filename: 'bundle.js',publicPath: '/scripts/'
},plugins: [
new webpack.HotModuleReplacementPlugin(),new webpack.NoErrorsPlugin(),new ExtractTextPlugin('styles/styles.css',{
allChunks: true
})
],resolve: {
extensions: ['','.js','.jsx']
},module: {
loaders: [{
test: /\.jsx?$/,loaders: ['react-hot','babel'],include: path.join(__dirname,'scripts')
},{
test: /\.css$/,loader: ExtractTextPlugin.extract('style-loader','css-loader')
}]
}
};
@H_301_2@index.js：
import React from 'react';
import App from './App';
React.render(<App />,document.getElementById('root'));
@H_301_2@App.js：
import React from 'react';
require('../styles/app.css');
export default class App extends React.Component {
render() {
return (
<h1>Hello,world.</h1>
);
}
}
@H_301_2@index.html：
<html>
<head>
<link rel="stylesheet" href="/styles/styles.css">
</head>
<body>
<div id='root'></div>
</body>
<script src="/scripts/bundle.js"></script>
</html>
@H_301_2@styles.css返回404
@H_301_2@任何想法这里可能会出错。如果我不使用ExtractTextPlugin，只需在config中这样做：
module: {
loaders: [
{ test: /\.css$/,loader: "style-loader!css-loader" }
]
}
@H_301_2@然后我得到的CSS应用于页面正确，但显然这不是来自一个CSS文件
@H_301_2@这是我第一次尝试使用webpack，所以可能做一些noob错误
@H_301_2@有任何想法吗？
解决方法
ExtractTextPlugin需要在两个地方添加：在加载程序和作为插件。这里是从
stylesheets documentation拉出的例子。
// webpack.config.js
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
// The standard entry point and output config
entry: {
posts: "./posts",post: "./post",about: "./about"
},output: {
filename: "[name].js",chunkFilename: "[id].js"
},module: {
loaders: [
// Extract css files
{
test: /\.css$/,loader: ExtractTextPlugin.extract("style-loader","css-loader")
},// Optionally extract less files
// or any other compile-to-css language
{
test: /\.less$/,"css-loader!less-loader")
}
// You could also use other loaders the same way. I. e. the autoprefixer-loader
]
},// Use the plugin to specify the resulting filename (and add needed behavior to the compiler)
plugins: [
new ExtractTextPlugin("[name].css")
]
}
