【问题描述】:
根据 styled-components v4,.extend 已弃用,扩展或组合组件的正确方法是:
const ButtonA = styled('button')`color: ${props => props.color};`
const ButtonB = styled(ButtonA)`background: 'white';`
但是我找不到使用 TS 执行此操作的正确方法,因为我遇到了一些错误,例如:
import styled from "styled-components";
// Let's create ButtonA
type ButtonAProps = { a: string };
const ButtonA = styled<ButtonAProps, "button">("button")`
color: ${props => props.a};
`;
// So, here is what I've tried
// Fail #1
// =======
type ButtonBProps = { b: string };
const ButtonB = styled<ButtonBProps, ButtonAProps>(ButtonA)`
background: ${props => props.b};
`; // Here I get autocompletion only for B props :(
const Test = () => <ButtonB a="something" />; // And here I get autocompletion only for A props :(
// Fail #2
// =======
type ButtonBProps = { b: string } & ButtonAProps;
const ButtonB = styled<ButtonBProps, ButtonAProps>(ButtonA)`
background: ${props => props.b};
`; // Here I get autocompletion for A & B props, good!
const Test = () => <ButtonB a="something" />; // Here I still get autocompletion only for A props :(
// Fail #3
// =======
type ButtonBProps = { b: string } & ButtonAProps;
const ButtonB = styled<ButtonBProps, ButtonBProps>(ButtonA)` // Property 'b' is missing in type 'ButtonAProps', of course
background: ${props => props.b};
`; // Here I get "props has implicitly any type"
const Test = () => <ButtonB />; // Here I don't get any type checking at all
似乎快到了,但无法弄清楚。
有什么建议吗?谢谢!
