I have a react app with CSS files working fine.
I need to start using SCSS so the following changes:
- Install
node-sassandsass-loader - Change the imports from
.cssto.scss - Change file extension from
.cssto.scss
But my pages are not loading properly:
Current behavior: 
Expected behavior: 
My code:
package.json
{
"name": "frontend",
"version": "0.1.0",
"private": true,
"dependencies": {
"@coreui/coreui": "^3.0.0",
"@stardust-ui/docs-components": "^0.40.0",
"axios": "^0.19.0",
"bootstrap": "^4.4.1",
"compass": "^0.1.1",

"prettier": "^1.6.1",
"prop-types": "^15.7.2",
"react": "^16.10.2",
"react-bootstrap": "^1.0.0-beta.16",

"eject": "react-scripts eject"
},
"devDependencies": {
"node-sass": "^4.13.1",
"sass-loader": "^8.0.2"
}
}
I injected the code for the loaders in node_modules/react-scripts/config/webpack.config.dev.js like this:
// Process JS with Babel.
{
test: /\.(js|jsx|mjs)$/,
include: paths.appSrc,
loader: require.resolve('babel-loader'),
options: {
// @remove-on-eject-begin
babelrc: false,
presets: [require.resolve('babel-preset-react-app')],
// @remove-on-eject-end
// This is a feature of `babel-loader` for webpack (not Babel itself).
// It enables caching results in ./node_modules/.cache/babel-loader/
// directory for faster rebuilds.
cacheDirectory: true,
},
},
{
test: /\.scss$/,
loader: [
"css-loader",
"sass-loader"
]
},
Here is my component:
import React, { Component } from "react";
import '../../../general.scss';
import { Warning } from '../../../images/images_svg';
class Terminos extends Component{
state = { error: false }
saveAndContinue = () => {
if(this.props.values.terminos) {
this.props.nextStep()
}
else {
console.log(this.props.values.terminos_error)
this.props.mandar_error('terminos_error')
}
}
render() {
return (
<div className="formulario">
<div className="formulario-seccion-titulo">
<div className="formulario-seccion-barrita"/>
<div className="formulario-seccion-content">
Presentacion
</div>
</div>
<div className={this.props.values.terminos_error ? "formulario-seccion" : "formulario-seccion-red"}>
La actual pandemia que afecta al mundo trae consecuencias a nivel sanitario, económico y social. Lo que está ocurriendo con el COVID impacta de lleno, no sólo en la salud física de las personas, sino que también afecta de forma clara y contundente su salud mental.<br/><br/>
Ud. puede decidir si contestar o no la encuesta que sigue pero de hacerlo,acepta que los resultados de la misma sean compartidos con su empleador con el único fin de brindarle contención y asistencia. La encuesta debe completarse en las próximas 10 horas.<br/><br/>
<input type="checkbox"
id="terminos"
className="formulario-checkbox"
onChange={() => this.props.handleTerminos()}
checked={this.props.values.terminos}
/>
<label className="formulario-checkbox-label" htmlFor="terminos">
Acepto terminos y condiciones.
</label>
{this.props.values.terminos_error===false &&
<div className="formulario-seccion-error">
<div className="formulario-seccion-error-logo" >
<Warning color="#d93025"/>
</div>
Debes aceptar los terminos y condiciones para continuar
</div>
}
</div>
<div className="formulario-footer">
<button className="formulario-botones" onClick={this.saveAndContinue}>Siguiente</button>
</div>
</div>
)
}
}
export default Terminos;
If I change the import and the file extension from .scss to .css the page load properly.
I´m using npm start to develop and testing the code.
