Using the css-in-js method to add classes to a react component, how do I add multiple components?
Here is the classes variable:
const styles = theme => ({
container: {
display: 'flex',
flexWrap: 'wrap'
},
spacious: {
padding: 10
},
});
Here is how I used it:
return (<div className={ this.props.classes.container }>)
The above works, but is there a way to add both classes, without using the classNames npm package? Something like:
<div className={ this.props.classes.container + this.props.classes.spacious}>
you can use string interpolation:
<div className={`${this.props.classes.container} ${this.props.classes.spacious}`}>
You could use clsx. I noticed it used in the MUI buttons examples
First install it:
npm install --save clsx
Then import it in your component file:
import clsx from 'clsx';
Then use the imported function in your component:
<div className={ clsx(classes.container, classes.spacious)}>
you can install this package

and then use it like this
classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'
// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'
// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'
