在我的React应用程序中,我试图将JS react-pose
-@reach/router
样本转换为TypeScript,但是它不起作用。
以下是react-pose
中的相关类型:
import { ComponentType, HTMLProps } from 'react';
import { PoseElementProps } from './components/PoseElement/types';
import { DomPopmotionConfig } from 'popmotion-pose';
declare type DomPopmotionConfigFactory<T> = (props: PoseElementProps & T) => DomPopmotionConfig;
export declare type ComponentFactory<T> = (poseConfig?: DomPopmotionConfig | DomPopmotionConfigFactory<T>) => ComponentType<PoseElementProps & T>;
export declare type Posed = {
<T>(component: ComponentType<T>): ComponentFactory<T>;
[key: string]: ComponentFactory<HTMLProps<any>>;
};
declare const posed: Posed;
export default posed;
JS示例如下:
import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Link, Location } from '@reach/router';
import posed, { PoseGroup } from 'react-pose';
import Home from './pages/home';
import About from './pages/about';
import './styles.css';
const RouteContainer = posed.div({
enter: { opacity: 1, delay: 300, beforeChildren: 300 },
exit: { opacity: 0 }
});
const PosedRouter = ({ children }) => (
<Location>
{({ location }) => (
<PoseGroup>
<RouteContainer key={location.key}>
<Router location={location}>{children}</Router>
</RouteContainer>
</PoseGroup>
)}
</Location>
);
const App = () => (
<div id="site-container">
<header>
<h1>Route transitions with Pose and Reach Router</h1>
</header>
<div id="content-container">
<ul id="site-nav">
<li>
<Link to="/">Home</Link>
</li>
<li>
<Link to="/about">About</Link>
</li>
</ul>
<PosedRouter>
<Home path="/" />
<About path="/about" />
</PosedRouter>
</div>
</div>
);
ReactDOM.render(<App />, document.getElementById('root'));

我被困在这里:
import * as React from 'react';
import { Router, Link, Location } from '@reach/router';
import { ComponentFactory } from 'react-pose/lib/posed';
import posed, { PoseGroup } from 'react-pose';
const RouteContainer: ComponentFactory<React.HTMLProps<any>> = posed.div({
enter: { opacity: 1, delay: 300, beforeChildren: 300 },
exit: { opacity: 0 }
});
const PosedRouter: Location = ({ children }: { children: React.ReactNode }) => (
<Location>
{({ location }) => (
<PoseGroup>
<RouteContainer key={location.key}>
<Router location={location}>{children}</Router>
</RouteContainer>
</PoseGroup>
)}
</Location>
);
在<RouteContainer key={location.key}>
上说:

这使我感到困惑,因为键入看起来正确。我不想在这里使用匿名签名并坚持打字。
我该如何解决这个问题?
答案 0 :(得分:0)
问题是在第一个渲染ordersRef = FirebaseDatabase.getInstance().getReference().child("Usuarios").child(currentUserID).child("Pedidos");
上未定义。这可能就是为什么您收到隐含的错误消息并引用未定义内容的原因。我使用了location.key
。似乎没有任何问题。使用location.pathname
会很棒,但是在location.key
中,它在第一个渲染器上是未定义的。
