[英]How to import css file for into Component .jsx file
我試圖使用react-day-Pickers組件,但我無法弄清楚如何導入.css文件,我不斷收到錯誤:
Module parse failed:
/Users/qliu/Documents/workspace/AppNexus/pricing_ui/contract-ui/app_contract-ui/node_modules/react-day-picker/lib/style.css Unexpected token (3:0)
You may need an appropriate loader to handle this file type.
SyntaxError: Unexpected token (3:0)
我在我的package.json中安裝了"css-loader": "^0.19.0",
這里是我的Calender.jsx文件:
import React from "react";
import DayPicker, { DateUtils } from "react-day-picker";
import "../../../node_modules/react-day-picker/lib/style.css"; // <==== ERROR ON THIS LINE
export default class Calender extends React.Component {
state = {
selectedDay: null
};
handleDayClick(e, day, modifiers) {
if (modifiers.indexOf("disabled") > -1) {
console.log("User clicked a disabled day.");
return;
}
this.setState({
selectedDay: day
});
}
render() {
// Add the `selected` modifier to the cell of the clicked day
const modifiers = {
disabled: DateUtils.isPastDay,
selected: day => DateUtils.isSameDay(this.state.selectedDay, day)
};
return <DayPicker enableOutsideDays modifiers={ modifiers } onDayClick={ this.handleDayClick.bind(this) } />;
}
}
這是我的webpack.config.js:
var path = require('path');
var webpack = require('webpack');
var settings = require('./src/server/config/settings');
var LessPluginAutoPrefix = require('less-plugin-autoprefix');
module.exports = {
devtool: '#source-map',
resolve: {
extensions: ['', '.jsx', '.js']
},
entry: [
'webpack-hot-middleware/client',
'./src/client/index.jsx'
],
externals: {
'react': 'React',
'react-dom': 'ReactDOM',
// to avoid duplicate import of React with react-addons-css-transition-group
'./React': 'React',
'./ReactDOM': 'ReactDOM',
config: 'config'
},
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js',
publicPath: '/'
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin()
],
lessLoader: {
lessPlugins: [
new LessPluginAutoPrefix({ browsers: ['last 2 versions'] })
]
},
module: {
loaders: [{
test: /\.(js|jsx)$/,
loaders: ['babel'],
exclude: /node_modules/
},
{
test: /\.less$/,
loader: 'style!css!less'
},
{
test: /\.json$/,
loader: 'json-loader'
}]
}
};
你怎么編譯這個? 如果是webpack,你可能需要引入樣式加載器並在webpack配置的module.loaders
數組中包含這樣的東西:
{
test: /\.css$/,
loader: "style!css"
}
更新 :現在提供了webpack.config.js,我們可以確認它需要在module.loaders
數組中進行更改。 OP使用較少的加載器並且僅檢查.less
文件,因此確切的加載器對象應該是:
{
test: /\.(less|css)$/,
loader: 'style!css!less'
}
正如@Q劉建議。 保留原始位,好像有人來這里導入.css文件時出錯,很可能是他們需要的。
我在我的webpack配置中使用了以下內容並且它有效:
test: /\\.css$/, use: [ 'style-loader', { loader: 'css-loader', options: { modules: true, }, }, ],
JSX不是CSS。 在主HTML文件中,只需將<link>
元素添加到CSS文件中,React生成的DOM將使用它。
