cxs is a minimal css-in-js solution that uses an atomic css approach to maximize performance and deduplication
npm install @olasearch/styled
cxs works with any framework, but this example uses React for demonstration purposes.
import React from 'react'
import cxs from 'cxs'
const Box = (props) => {
return (
<div {...props} className={className} />
)
}
const className = cxs({
padding: '32px',
backgroundColor: 'tomato'
})
export default Box
const className = cxs({
color: 'tomato',
':hover': {
color: 'black'
}
})
const className = cxs({
fontSize: '32px',
'@media screen and (min-width: 40em)': {
fontSize: '48px'
}
})
const className = cxs({
color: 'black',
' > a': {
color: 'tomato'
}
})
For Node.js environments, use the css() method to return the static CSS string after rendering a view.
import React from 'react'
import ReactDOMServer from 'react-dom/server'
import cxs from 'cxs'
import App from './App'
const html = ReactDOMServer.renderToString(<App />)
const css = cxs.css()
const doc = `<!DOCTYPE html>
<style>${css}</style>
${html}
`
// Reset the cache for the next render
cxs.reset()
Note: cxs does not currently have a mechanism for rehydrating styles on the client, so use with caution in universal JavaScript applications.
cxs also has an alternative higher order component API for creating styled React components, similar to the styled-components API.
import cxs from 'cxs/component'
const Heading = cxs('h1')({
margin: 0,
fontSize: '32px',
lineHeight: 1.25
})
To extend a cxs component, pass it to the component creator function.
const Button = cxs('button')({
color: 'white',
backgroundColor: 'blue'
})
const TomatoButton = cxs(Button)({
backgroundColor: 'tomato'
})
Any component can be passed to cxs to add styles.
import { Link } from 'react-router'
const MyLink = cxs(Link)({
color: 'tomato'
})
Note: components must accept className as a prop to work with cxs.
cxs components can also handle dynamic styling based on props by passing a function as an argument
const Heading = cxs('h1')(props => ({
color: props.color
}))
To remove style props from the rendered HTML element,
use the prop-types package to define propTypes on a component.
cxs/component will remove any prop that matches a key from the propTypes object.
import cxs from 'cxs/component'
import PropTypes from 'prop-types'
const Heading = cxs('h2')(props => ({
fontSize: props.big ? '48px' : '32px'
}))
Heading.propTypes = {
big: PropTypes.bool
}
Style utility functions, like those in styled-system, can be used with cxs/component.
import cxs from 'cxs/component'
import {
space,
color
} from 'styled-system'
const Heading = cxs('h2')(space, color)
Theming is supported with the <ThemeProvider> component.
import React from 'react'
import ThemeProvider from 'cxs/ThemeProvider'
import theme from './theme'
const App = props => (
<ThemeProvider theme={theme}>
<Heading>
Hello
</Heading>
</ThemeProvider>
)
import cxs from 'cxs/component'
const Heading = cxs('h2')(props => ({
fontSize: props.theme.fontSizes[4] + 'px',
color: props.theme.blue
}))
cxs(...styles)Accepts styles objects or functions that return style objects and returns a className string.
cxs.css()Returns the rendered CSS string for static and server-side rendering.
cxs.reset()Resets the cache for server-side rendering
cxs/componentA styled-components-like API for creating React components with cxs.
cxs does not handle vendor prefixing to keep the module size at a minimum.
For previous versions of cxs, see the v3 branch or v4 branch
