How to import css file for into Component .jsx file - css

Question

I am trying to use the react-day-pickers component like so but I can't figure out how to import the .css file and I keep getting the error:
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)
I have "css-loader": "^0.19.0", in my package.json installed and
here is my Calender.jsx file:
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) } />;
}
}
and this is my 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'
}]
}
};

Answer 1

How are you compiling this? If it's webpack, you'd probably need to bring in the style-loader and include something like this in the module.loaders array in your webpack config:
{
test: /\.css$/,
loader: "style!css"
}
Update: With the webpack.config.js now provided, we can confirm it needed a change in the module.loaders array. OP was using a less loader and only checking for .less files, so the exact loader object should read:
{
test: /\.(less|css)$/,
loader: 'style!css!less'
}
As suggested by #Q Liu. Leaving the original bit as if someone comes here with an error importing a .css file, it's likely what they need.

I used the following in my webpack config and it worked:
test: /\.css$/,
use: [
'style-loader',
{
loader: 'css-loader',
options: {
modules: true,
},
},
],

JSX is not CSS. In your main HTML file, just add a <link> element to the CSS file, and the DOM generated by React will use it.
