Styled Components and Emotion
OneJS provides APIs that are equivalent to the styled, css, and attr APIs from Styled Components, and also the css API from Emotion.
These are available from preact/styled (technically, it's provided by the onejs-preact package, but the shortcut mappings in tsconfig.json allows you to just use preact/styled).
TSX
import { h, render } from "preact"
import styled, { CompType, uss } from "preact/styled"
const Button = styled.button`
border-width: 0;
border-radius: 3px;
background-color: green;
color: white;
&:hover {
background-color: red;
}
${props => props.primary && uss`
background-color: white;
color: black;
`}
` as CompType<{ primary: boolean }, JSX.Button>
render(<Button text="Hello!" primary />, document.body)attr also works as you'd expect:
TSX
import styled from "preact/styled"
import { h, render } from "preact"
const Jin = styled.button.attrs(props => ({
text: props.foo
}))`
color: red;
`
const Cup = styled(Jin).attrs(props => ({
text: "Foooooo",
bar: props.bar || 50
}))`
font-size: ${props => props.bar}px;
`
render(<Cup foo="My Text" />, document.body)Emotion's css (which is different from Styled Components' css) is available as emo from onejs/styled:
TSX
import { emo } from "onejs"
import { h, render } from "preact"
const Foo = (props) => {
return <div class={emo`
font-size: ${props.size ?? 10}px;
color: red;
`}>Hello</div>
}
render(<Foo size={30} />, document.body)Please get in our Discord to share what other APIs you'd like to see supported.
