I'm trying to integrate typescript into our project and so far I stumbled upon one issue with styled-components library
Consider this component
import * as React from "react";
import styled from "styled-components/native";
import { TouchableOpacity } from "react-native";
// -- types ----------------------------------------------------------------- //
export interface Props {
onPress: any;
src: any;
width: string;
height: string;
}
// -- styling --------------------------------------------------------------- //
const Icon = styled.Image`
width: ${(p: Props) => p.width};
height: ${(p: Props) => p.height};
`;
class TouchableIcon extends React.Component<Props> {
// -- default props ------------------------------------------------------- //
static defaultProps: Partial<Props> = {
src: null,
width: "20px",
height: "20px"
};
// -- render -------------------------------------------------------------- //
render() {
const { onPress, src, width, height } = this.props;
return (
<TouchableOpacity onPress={onPress}>
<Icon source={src} width={width} height={height} />
</TouchableOpacity>
);
}
}
export default TouchableIcon;
Following line throws 3 errors, that are same in nature <Icon source={src} width={width} height={height} />
Type {source: any; width: string; height: string;} is not assignable to type IntrinsicAttributes ... Property 'onPress' is missing in type {source: any; width: string; height: string;}
Not entirely sure what this is and how to fix it, do I somehow need to declare these on Icon
or something of this sort?
EDIT: typescript v2.6.1, styled-components v2.2.3
There have been some recent developments and with a new version of Typescript (eg. 3.0.1) and styled-components (eg. 3.4.5) there's no need for a separate helper. You can specify the interface/type of your props to styled-components directly.
interface Props {
onPress: any;
src: any;
width: string;
height: string;
}
const Icon = styled.Image<Props>`
width: ${p => p.width};
height: ${p => p.height};
`;
and if you want to be more precise and ignore the onPress
const Icon = styled.Image<Pick<Props, 'src' | 'width' | 'height'>>`
width: ${p => p.width};
height: ${p => p.height};
`;
