react-router

问题 I'm trying to use the Material-UI breadcrumb with react-router. How can I programatically detect the current route. On the Material-UI website there is an example on how to use it but it requires the usage of a static breadcrumbNameMap. I already tried to split the pathname by using the HOC "withRouter" but it doesn't work. import React from "react"; import { makeStyles } from "@material-ui/core/styles"; import { Breadcrumbs, Link, Paper, Typography} from "@material-ui/core"; import {

问题 I have a simple web page with login and search pages. I also have a navbar at the top to allow for switching between the two. The basic App.js looks as follows: const history = createBrowserHistory(); function App() { return ( <Router history={history}> <CustomLayout> <Switch> <BaseRouter/> </Switch> </CustomLayout> </Router> ); } export default App; Now, the BaseRouter and CustomLayout are just const BaseRouter = () => ( <div> <Route exact path={"/list"} component={ItemsList}/> <Route path={

问题 I am building a app with React and Electron and am using React Router Dom for navigation (I am using the HashRouter as it will not be on a server in production). I am trying to open a new electron window and display a page made with React in it but I cannot figure out how to access a react router route using the file protocol because each page does not get its own html file. Does anyone know how I can access that route using the file protocol? My home page is loaded into the app using this

问题 I'm trying to understand how to best test that react-router behaves as expected with @testing-library/react. The simplest test I can think of, is to verify that clicking a link changes the URL. I know that ideally I should test that clicking on a link renders a new component, but that adds a lot of boilerplate to the test. So here's my failing example: import { MemoryRouter } from 'react-router-dom'; import { render } from '@testing-library/react'; import { createMemoryHistory } from 'history

问题 I have upgraded to React Router V4 and now struggling with the history.push method. I have an index.js file: import React from "react"; import { render } from "react-dom"; import { BrowserRouter, Route } from 'react-router-dom'; import createBrowserHistory from 'history/createBrowserHistory'; const history = createBrowserHistory(); import { Main} from "./components/Main"; import { About } from "./components/About"; import { Cars} from "./components/Cars"; class App extends React.Component {
