Use react CSS modules

[vincaslt]

I assumed create-react-app uses react-css-modules, but this code does not work (no styles applied):

import React from 'react'
import styles from './styles.css'

const TextField = ({children}) => (
  <div className={styles.inputContainer}>
    <span className={styles.inputLabel}>{children}</span>
    <input className={styles.inputField}/>
  </div>
)

export default TextField

It does, however, work when classes are defined as strings rather than scoped to this component. I think it wouldn't hurt to have this available for projects using create-react-app, what do you think?

See the discussion in #90 (and the one in #78 too) please!

my-app uses react-css-modules in create-react-app no work

import React, {Component} from 'react';
import {immutableRenderDecorator} from 'react-immutable-render-mixin';
import CSSModules from 'react-css-modules';
import classnames from 'classnames';
import styles from '../css/style.scss';

// @immutableRenderDecorator
// @CSSModules(styles, {allowMultiple: true})
class lineBar extends Component {
    render() {
        const {left, width} = this.props;
        console.log(styles,'@styles');
        const classes = classnames({inkBar: true});

        return (
            <div styleName={classes}
                style={{
                    WebkitTransform: `translate3d(${left}px, 0, 0)`,
                    transform: `translate3d(${left}px, 0, 0)`,
                    width: width
                }}
            >
            </div>
        )
    }
}

export default immutableRenderDecorator(CSSModules(lineBar,styles, {allowMultiple: true}));

error message:

Create React App does not use or support CSS Modules. You can eject and add them if you'd like.

Great, recent article on using CSS Modules after ejecting Create React App: https://medium.com/nulogy/how-to-use-css-modules-with-create-react-app-9e44bec2b5c2

This article was a solution for getting CSS Modules, SASS, LESS and Stylus:

create-react-app my-app --scripts-version custom-react-scripts

exactly. the same issue with auth0-react-scripts. Shared forks considered harmful. 2017-07-05 7:25 GMT+08:00 Dan Abramov <[email protected]>:

I wouldn't say anything is "considered harmful", we actually appreciate the community publishing forks. I just want to make sure that people reading this thread in the future will have right expectations with regards to level of support we can provide.

Hi gaearon, i'm wondering why css modules does not support in create-react-app. I think each component has own style.

[gaearon]

We might support it as opt-in in the future. We don't support it by default because it's not a standard syntax, some tools don't understand it, and it's very confusing to beginners who aren't used to importing specific classnames.

[dennisat]

Maybe add it as a option.

[gaearon]

CSS modules are now supported.
