REACT/PROP-TYES打字脚本REACT组件中的eslint错误 [英] react/prop-types eslint error in typescript react component

问题描述

我正在尝试设置typescript-react-eslint项目，但无法通过此样板组件的eslint错误：

import * as React from "react";

interface ButtonProps {
  children?: React.ReactNode,
  onClick?: (e: any) => void,
}

const styles = {
  border: "1px solid #eee",
  borderRadius: 3,
  backgroundColor: "#FFFFFF",
  cursor: "pointer",
  fontSize: 15,
  padding: "3px 10px",
  margin: 10
};

const Button: React.FunctionComponent<ButtonProps> = props => (
  <button onClick={props.onClick} style={styles} type="button">
    {props.children}
  </button>
);

Button.defaultProps = {
  children: null,
  onClick: () => {}
};
export default Button;

错误为：

  19:26  error  'onClick' is missing in props validation   react/prop-types
  20:12  error  'children' is missing in props validation  react/prop-types

好像是在抱怨html<button>的接口没有定义？ 否则，它可能是Button组件本身，但它不应该从我传递到那里的<ButtonProps>接口获取类型信息吗？

我尝试显式设置children和onClick如下：

Button.propTypes = {
  children?: React.ReactNode,
  onClick?: (e: any) => void
};

它绕过eslint错误，但组件本身停止工作。 我做错了什么？

附注：这是我的.eslintrc.json

{
    "env": {
        "browser": true,
        "commonjs": true,
        "es6": true
    },
    "extends": [
        "eslint:recommended",
        "plugin:react/recommended",
        "plugin:@typescript-eslint/eslint-recommended"
    ],
    "globals": {
        "Atomics": "readonly",
        "SharedArrayBuffer": "readonly"
    },
    "settings": {
        "react": {
            "pragma": "React",
            "version": "detect"
        }
    },
    "parser": "@typescript-eslint/parser",
    "parserOptions": {
        "ecmaFeatures": {
            "jsx": true
        },
        "ecmaVersion": 2018,
        "sourceType": "module"
    },
    "plugins": [
        "react",
        "@typescript-eslint"
    ],
    "rules": {
        "indent": [
            "error",
            2
        ],
        "linebreak-style": [
            "error",
            "unix"
        ],
        "quotes": [
            "error",
            "double"
        ],
        "semi": [
            "error",
            "always"
        ]
    }
}

推荐答案

我最终将组件重写为：

const Button = ({ children, onClick }: ButtonProps) => {
  return <button onClick={onClick} style={styles} type="button">
    {children}
  </button>;
};

eslint忽略了: React.FC<ButtonProps>部分，因此我决定以更直接的方式提供道具类型
