React Typescript - 在路由中传递时如何将类型添加到 location.state [英] React Typescript - How add Types to location.state when passed in a Route

问题描述

当我将 react-router props 传递给 Route 中的一个组件时出现错误，因为我有特定的状态，我传递了这个组件，但错误显示在我的 Route 中.

这是路线代码:

<路由精确的路径='/翻转时间线'渲染={道具=><FliplTimeline {...props}/>

在另一个组件中，我在下面称之为

props.history.push(`/flipltimeline`, {批准:singleFliplApprovals，调查号，单位:单位，成本:成本});

这是组件的代码.我终于得到了 Typescript 来编译它，但我不得不合并 LocationState &TimelineState 以使其正常工作.但是现在当我将道具发送到我的 FliplTimeline 组件时，Typescript 会抛出上面的屏幕截图.任何人都知道如何解决这个问题?

history.tsx

import { createBrowserHistory } from 'history';让 baseNameProd = '';if (process.env.NODE_ENV !== 'production') {console.log('看起来我们处于开发模式！');baseNameProd = '';} 别的 {baseNameProd = '/flipl';}const customHistory {基名:baseNameProd});导出默认自定义历史；

FliplTimeline.tsx

import * as React from 'react';从历史"导入{历史记录，位置状态}；接口 FliplTimelineLocationState {批准:任何；调查ID:号码；单位:字符串；成本:数量；}接口 TimelineState{状态:翻转时间线位置状态；}界面道具{历史:历史；位置:LocationState &时间线状态；}功能翻转时间线(道具:道具){返回 (<ModuleTemplate title='状态时间线'副标题=''><FliplTimelineJumbotron className='bg-primary-darker shadow-4 line-height-serif-4'>
<跨度className='font-mono-2xl text-white'风格={{垂直对齐:'中间'}}>翻转{' '}</span><跨度className='font-mono-xl text-gold'风格={{垂直对齐:'中间'}}>{props.location.state.InvestigationID}</span>

更新:添加了我的 history.tsx 文件，我在其中为 React-Router 创建了自己的历史记录.也在导入语句中添加.

更新:尝试将我的 FliplTimeline 组件更改为具有此界面

import { RouteComponentProps } from 'react-router-dom'功能翻转时间线(道具:RouteComponentProps){

我收到 2 个错误.第一个是这个，另一个说道具的形状是错误的.想法?

更新:我终于能够为我的组件获得正确的 props 声明.

import { RouteComponentProps } from 'react-router-dom';接口 FliplTimelineLocationState {批准:任何；调查ID:号码；单位:字符串；成本:数量；}功能翻转时间线(props: RouteComponentProps<{}, any, FliplTimelineLocationState |任何>)

解决方案

我能够让它工作.

import { RouteComponentProps } from 'react-router-dom';接口 FliplTimelineLocationState {批准:任何；调查ID:号码；单位:字符串；成本:数量；}功能翻转时间线(props: RouteComponentProps<{}, any, FliplTimelineLocationState |任何>)

I am getting an error when I pass react-router props sent to a component in a Route because I have specific state that I pass this component but the error shows up in my Route.

Here is the Route code:

<Route
    exact
    path='/flipltimeline'
    render={props => <FliplTimeline {...props} />

In another component I call this below

props.history.push(`/flipltimeline`, {
      Approval: singleFliplApprovals,
      InvestigationID,
      Unit: unit,
      Cost: cost
    });

Here is the code for the Component. I finally got Typescript to compile this but I had to merge LocationState & TimelineState to get this to work. But now Typescript throws the above screenshot when I send props to my FliplTimeline component. Anyone have and idea how to fix this?

history.tsx

import { createBrowserHistory } from 'history';

let baseNameProd = '';

if (process.env.NODE_ENV !== 'production') {
  console.log('Looks like we are in development mode!');
  baseNameProd = '';
} else {
  baseNameProd = '/flipl';
}

const customHistory = createBrowserHistory({
  basename: baseNameProd
});

export default customHistory;

FliplTimeline.tsx

import * as React from 'react';
import { History, LocationState } from 'history';

interface FliplTimelineLocationState {
  Approval: any;
  InvestigationID: number;
  Unit: string;
  Cost: number;
}

interface TimelineState{
  state: FliplTimelineLocationState;
}

interface Props {
  history: History;
  location: LocationState & TimelineState;
}

function FliplTimeline(props: Props) {
  return (
    <ModuleTemplate title='Status Timeline' subtitle=''>
      <FliplTimelineJumbotron className='bg-primary-darker shadow-4 line-height-serif-4'>
        <div className='grid-row'>
          <div className='grid-col-4'>
            <span
              className='font-mono-2xl text-white'
              style={{
                verticalAlign: 'middle'
              }}
            >
              FLIPL{' '}
            </span>
            <span
              className='font-mono-xl text-gold'
              style={{
                verticalAlign: 'middle'
              }}
            >
              {props.location.state.InvestigationID}
            </span>

Update: Added my history.tsx file in which I created my own history for React-Router. Also added in the import statements.

Update: Tried to change my FliplTimeline component to have this interface

import { RouteComponentProps } from 'react-router-dom'

function FliplTimeline(props: RouteComponentProps ) {

I get 2 errors. First one is this one and another that says that the shape of the props are wrong. Ideas?

Update: I was able to finally get the right props declaration for my component.

import { RouteComponentProps } from 'react-router-dom';

interface FliplTimelineLocationState {
  Approval: any;
  InvestigationID: number;
  Unit: string;
  Cost: number;
}

function FliplTimeline(
  props: RouteComponentProps<{}, any, FliplTimelineLocationState | any>
)

解决方案

I was able to get it working.

import { RouteComponentProps } from 'react-router-dom';

interface FliplTimelineLocationState {
  Approval: any;
  InvestigationID: number;
  Unit: string;
  Cost: number;
}

function FliplTimeline(
  props: RouteComponentProps<{}, any, FliplTimelineLocationState | any>
)
