我能够将高阶组件 withStyles
和 withRouter
一起使用而没有问题,但升级到最新版本已导致错误。
https://reactjs.org/docs/higher-order-components.html
使用的软件包:
"@types/react-router": "^4.0.20",
"@types/react-router-dom": "^4.2.3",
"material-ui": "^1.0.0-beta.24",
"react-router": "^4.2.0",
"react-router-dom": "^4.2.2",
我一直在研究库的测试,并一个一个一个一个一个一个问题不是问题:
https://github.com/definitelytyped/definitelytyped/blob/master/types/react-router/test/withrouter.tsx
https://github.com/mui-org/material-ui/blob/v1-beta/test/typescript/styles.spec.tsx
但是,当我尝试结合它们时,我会得到这个错误:
ts2322:type'{text:" foo";}'不能分配给类型 'intinsInsICATTRIBUTES&选择 withStyles," text" ...'。键入'{text:" foo";}' 是 无法分配给'pick& withstyles,"文本" |"类" |"主题">'。财产 类型'{text:" foo"中缺少"类";}'。
代码,错误仅针对行<DecoratedComponent text="foo" />;
import * as React from 'react';
import * as ReactDOM from 'react-dom';
import * as ReactRouter from 'react-router';
import { Redirect, Route, Switch, withRouter, RouteComponentProps } from 'react-router-dom';
import Grid from 'material-ui/Grid';
import { withStyles, WithStyles, StyleRulesCallback } from 'material-ui/styles';
import { CustomTheme } from 'Features/Client/Styles/MainTheme';
import 'Styles/App.css';
import * as es6ObjectAssign from 'es6-object-assign';
es6ObjectAssign.polyfill();
type withStyleProps = 'mainStyle' | 'innerStyle';
const styles: StyleRulesCallback<withStyleProps> = (theme: CustomTheme) => ({
mainStyle: {
backgroundColor: '#F7F7F7',
minHeight: '100vh',
} as React.CSSProperties,
innerStyle: {
padding: theme.spacing.small,
paddingTop: 0,
paddingBottom: 0,
maxWidth: '90rem',
margin: '0 auto',
} as React.CSSProperties,
});
interface IProps {
text: string;
}
interface IState {
}
class App extends React.Component<IProps & WithStyles<withStyleProps>, IState> {
constructor(props: IProps & WithStyles<withStyleProps>) {
super(props);
this.state = {
};
}
render() {
const { classes } = this.props;
return (
<div className={classes.mainStyle}>
<div className={classes.innerStyle}>
<DecoratedComponent text="foo" />;
</div>
</div>
);
}
}
export default withStyles(styles)(App);
const DecoratedComponent = withStyles(styles)(withRouter(
class extends React.Component<IProps & RouteComponentProps<{}> & WithStyles<withStyleProps>> {
render() {
const { classes, text } = this.props;
return <div className={classes.mainStyle}>{text}</div>;
}
}
));
更新:
用于使用构造函数的组件的解决方案,并且不会复制和粘贴IProps2 & RouteComponentProps<IProps> & WithStyles<withStyleProps>
interface IProps2 {
text: string;
}
type Props2 = IProps2 & RouteComponentProps<{}> & WithStyles<withStyleProps>;
const DecoratedComponent = withRouter(withStyles(styles)(
class extends React.Component<Props2> {
render() {
const { classes, text } = this.props;
return <div className={classes.mainStyle}>{text}</div>;
}
}
));
原始:
现在通过将withRouter
和withStyles
放在之后来解决。
const DecoratedComponent = withRouter(withStyles(styles)(
class extends React.Component<IProps & RouteComponentProps<IProps> & WithStyles<withStyleProps>> {
render() {
const { classes, text } = this.props;
return <div className={classes.mainStyle}>{text}</div>;
}
}
));
