styletron-inferno
Styletron bindings for Inferno.
Provider
Provider is a component that exposes a styletron instance to child components on their context.
An instance of styletron-server or styletron-client must be passed to Provider as a styletron prop.
Server-side Example
import StyletronServer from 'styletron-server';
import { Provider } from 'styletron-inferno';
import { renderToString } from 'inferno-server';
import express from 'express';
import App from './path/to/app';
function renderHMTL() {
const styletron = new StyletronServer();
const root = renderToString(
<Provider styletron={styletron}>
<App/>
</Provider>
);
// NOTE: getStylesheetsHtml must be called after renderToString
const stylesheets = styletron.getStylesheetsHtml('my-custom-class');
return `
<!DOCTYPE html>
<html>
<head>
${stylesheets}
</head>
<body>
<div id="root">${root}</div>
</body>
</html>
`;
}
const app = express();
app.get('/', (req, res) => {
res.send(renderHMTL());
});Client-side Example
import { render } from 'inferno';
import { Provider } from 'styletron-inferno';
import StyletronClient from 'styletron-client';
import App from './path/to/app';
const stylesheets = document.getElementsByClassName('my-custom-class');
const styletron = new StyletronClient(stylesheets);
render((
<Provider styletron={styletron}>
<App/>
</Provider>
), document.getElementsById('root'));styled(name, styles)
const StyledComponent = styled(
name: string|function,
styles: object|function
):VNodename can be a string to create a styled element, or it can be a class|function component.
styles can be an object with CSS property/value pairs, or it can be a function that returns an object with CSS property/value pairs. When a function is passed, it is called with props and context.
import { styled } from 'styletron-inferno';
const StaticStyledDiv = styled('div', {
backgroundColor: 'lightblue',
fontSize: '12px'
});
const DynamicStyledDiv = styled('div', (props) => ({
backgroundColor: props.alert ? 'orange' : 'lightblue',
fontSize: '12px'
}));
const ComposedStyledDiv = styled(StaticStyledDiv, (props) => ({
backgroundColor: props.alert ? 'red' : 'lime',
boxShadow: '0 2px 4px darkgray'
}));
Inferno.render((
<div>
<StaticStyledDiv/>
<DynamicStyledDiv alert={true}/>
<DynamicStyledDiv alert={false}/>
<ComposedStyledDiv alert={true}/>
<ComposedStyledDiv alert={false}/>
</div>
), document.getElementsById('root'));If you want a ref to the inner DOMElement or rendered Component instance, a special innerRef prop is provided. innerRef must be a function—string refs are not supported.
NOTE: ref does not work with functional components since they are stateless.
const StyledDiv = styled('div', {
backgroundColor: 'lightblue',
fontSize: '12px'
});
class SomeComponent extends Component {
componentDidMount() {
console.log(this.styledDiv);
}
render() {
return <StyledDiv innerRef={el => this.styledDiv = el}/>
}
}
