I want to import a CSS file into a react component.
I've tried import disabledLink from "../../../public/styles/disabledLink";
but I get the error below;
Module not found: Error: Cannot resolve 'file' or 'directory' ../../../public/styles/disabledLink in c:\Users\User\Documents\pizza-app\client\src\components @ ./client/src/components/ShoppingCartLink.js 19:20-66 Hash: 2d281bb98fe0a961f7c4 Version: webpack 1.13.2
C:\Users\User\Documents\pizza-app\client\public\styles\disabledLink.css
is the location of the CSS file I'm trying to load.
To me it seems like import is not looking up the correct path.
I thought with ../../../
it would start to look up the path three folder layers above.
C:\Users\User\Documents\pizza-app\client\src\components\ShoppingCartLink.js
is the location of the file that should import the CSS file.
What am I doing wrong and how can I fix it?

In cases where you just want to inject some styles from a stylesheet into a component without bundling in the whole stylesheet I recommend https://github.com/glortho/styled-import. For example:
const btnStyle = styledImport.react('../App.css', '.button')
// btnStyle is now { color: 'blue' } or whatever other rules you have in `.button`.
NOTE: I am the author of this lib, and I built it for cases where mass imports of styles and CSS modules are not the best or most viable solution.
CSS Modules let you use the same CSS class name in different files without worrying about naming clashes.
Button.module.css
.error {
background-color: red;
}
another-stylesheet.css
.error {
color: red;
}
Button.js
import React, { Component } from 'react';
import styles from './Button.module.css'; // Import css modules stylesheet as styles
import './another-stylesheet.css'; // Import regular stylesheet
class Button extends Component {
render() {
// reference as a js object
return <button className={styles.error}>Error Button</button>;
}
}
The following imports an external CSS file in a React component and outputs the CSS rules in the <head />
of the website.
npm install --save-dev style-loader
npm install --save-dev css-loader
module.exports = {
module: {
rules: [
{
test: /\.css$/,
use: [ 'style-loader', 'css-loader' ]
}
]
}
}
import './path/to/file.css';
You need to use css-loader when creating bundle with webpack.
Install it:
npm install css-loader --save-dev
And add it to loaders in your webpack configs:
module.exports = {
module: {
loaders: [
{ test: /\.css$/, loader: "style-loader!css-loader" },
// ...
]
}
};
After this, you will be able to include css files in js.
I would suggest using CSS Modules:
React
import React from 'react';
import styles from './table.css';
export default class Table extends React.Component {
render () {
return <div className={styles.table}>
<div className={styles.row}>
<div className={styles.cell}>A0</div>
<div className={styles.cell}>B0</div>
</div>
</div>;
}
}
Rendering the Component:
<div class="table__table___32osj">
<div class="table__row___2w27N">
<div class="table__cell___2w27N">A0</div>
<div class="table__cell___1oVw5">B0</div>
</div>
</div>
Install Style Loader and CSS Loader:
npm install --save-dev style-loader
npm install --save-dev css-loader
Configure webpack
module: {
loaders: [
{
test: /\.css$/,
loader: 'style-loader'
}, {
test: /\.css$/,
loader: 'css-loader',
query: {
modules: true,
localIdentName: '[name]__[local]___[hash:base64:5]'
}
}
]
}
The solutions above are completely changed and deprecated. If you want to use CSS modules (assuming you imported css-loaders) and I have been trying to find an answer for this for such a long time and finally did. The default webpack loader is quite different in the new version.
In your webpack, you need to find a part starting with cssRegex and replace it with this;
{
test: cssRegex,
exclude: cssModuleRegex,
use: getStyleLoaders({
importLoaders: 1,
modules: true,
localIdentName: '[name]__[local]__[hash:base64:5]'
}),
}
You can import your .css
file in .jsx
file
Here is an example -
import Content from '../content/content.jsx';
Using extract-css-chunks-webpack-plugin and css-loader loader work for me, see below:
webpack.config.js Import extract-css-chunks-webpack-plugin
const ExtractCssChunks = require('extract-css-chunks-webpack-plugin');
webpack.config.js Add the css rule, Extract css Chunks first then the css loader css-loader will embed them into the html document, ensure css-loader and extract-css-chunks-webpack-plugin are in the package.json dev dependencies
rules: [
{
test: /\.css$/,
use: [
{
loader: ExtractCssChunks.loader,
},
'css-loader',
],
}
]
webpack.config.js Make instance of the plugin
plugins: [
new ExtractCssChunks({
// Options similar to the same options in webpackOptions.output
// both options are optional
filename: '[name].css',
chunkFilename: '[id].css'
})
]
And now importing css is possible And now in a tsx file like index.tsx i can use import like this import './Tree.css' where Tree.css contains css rules like
body {
background: red;
}
My app is using typescript and this works for me, check my repo for the source : https://github.com/nickjohngray/staticbackeditor
You can also use the required module.
require('./componentName.css');
const React = require('react');
