我正在尝试使用 webpack 插件在我的 react.js
应用程序上将 SCSS 提取到 CSS:extract-text-webpack-plugin
。我没有收到任何错误,但是编译时我在页面上看不到任何样式。在下面的代码中,我只是试图将屏幕上呈现的 hello world 的颜色从黑色更改为红色。这是我的文件:
webpack.config.js
var webpack = require('webpack');
var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
devtool: 'inline-source-map',
entry: [
'webpack-dev-server/client?http://127.0.0.1:8080/',
'webpack/hot/only-dev-server',
'./src/index.js',
'./sass/styles.scss'
],
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js'
},
resolve: {
modules: ['node_modules', 'src'],
extensions: ['.js', '.jsx']
},
module: {
rules: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
use: ['react-hot-loader', 'babel-loader']
},
{ // regular css files
test: /\.css$/,
loader: ExtractTextPlugin.extract({
loader: 'css-loader?importLoaders=1',
}),
},
{ // sass / scss loader for webpack
test: /\.(sass|scss)$/,
loader: ExtractTextPlugin.extract(['css-loader', 'sass-loader'])
}
]
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoEmitOnErrorsPlugin(),
new ExtractTextPlugin("styles.css")
]
};
样式.scss
$color : red;
.hello{
font-color: $color;
text-align: center;
}
app.js
import React from 'react';
export default class App extends React.Component {
render() {
return (
<div>
<h1 className = "hello">Hello World</h1>
</div>);
}
}
index.js
import React from 'react';
import { render } from 'react-dom';
import App from './components/app';
render ( <App />, document.getElementById('app'));
我错过了什么?
最佳答案
您的加载程序链中缺少 style-loader
。
来自 sass-loader docs :
Chain the sass-loader with the css-loader and the style-loader to immediately apply all styles to the DOM.
// webpack.config.js
module.exports = {
...
module: {
rules: [{
test: /\.scss$/,
use: [{
loader: "style-loader" // creates style nodes from JS strings
}, {
loader: "css-loader" // translates CSS into CommonJS
}, {
loader: "sass-loader" // compiles Sass to CSS
}]
}]
}
};
