I am tried to make a chat room application with react js,
but I have faced a problem when I tried to see just chatroom page then it's ok, but when I refresh the page then again show me the home page that mean show me both page in the chatroom page, I don't know why show me home page again,
I have tried this way:
import React from "react";
import { Router, Route } from "react-router-dom";
import HomePage from "./HomePage";
import TopBar from "./TopBar";
import { createBrowserHistory as createHistory } from "history";
import "./App.css";
import ChatRoomPage from "./ChatRoomPage";
const history = createHistory();
function App() {
console.log("Working");
return (
<div className="App">
<Router history={history}>
<TopBar />
<Route path="/:chatRoomId" component={HomePage} />
<Route
path="/chatroom"
exact
render={(props) => <ChatRoomPage {...props} />}
/>
</Router>
</div>
);
}
export default App;
any suggestion please.
You should use react router dom exact way
like: import { BrowswerRouter as Router, Route, Switch } from "react-router-dom";
then take upper the render router.
import React from "react";
import { BrowswerRouter as Router, Route, Switch } from "react-router-dom";
import HomePage from "./HomePage";
import TopBar from "./TopBar";
import { createBrowserHistory as createHistory } from "history";
import "./App.css";
import ChatRoomPage from "./ChatRoomPage";
const history = createHistory();
function App() {
console.log("Working");
return (
<div className="App">
<Router history={history}>
<TopBar />
<Switch>
<Route
path="/chatroom"
exact
render={(props) => <ChatRoomPage {...props} />}
/>
<Route path="/:chatRoomId" component={HomePage} />
</Switch>
</Router>
</div>
);
}
export default App;
So I'm new to react and I'm trying to authenticate with Google. The problem is every time I try to log in or signup with Google Authentication I'm shown a blank screen with some errors in the console.
This is my App component from where the error originates. The error based on userlocation hook,I guess. Initially, I was getting an error telling me that the location variable is undefined and I fixed that by moving by Router tags in index.js file and it worked. But, now again, its causing error.
import { BrowserRouter as Router, Route,Redirect, Switch } from "react-router-dom";

A few things missing here to debug your code.
For a start, make sure you wrap your Router around your App.js like this:
import { BrowserRouter } from "react-router-dom";
<BrowserRouter>
<App />
</BrowserRouter>
I have updated to the latest version of react/react-router/...
I am now trying to fix the various issues introduced by all the changes to those dependencies.
Note: my code was working before, it is not anymore because of the newer versions.
So I had this to handle my routes before:
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { Router, Route, IndexRoute, browserHistory } from 'react-router';
import {syncHistoryWithStore, push} from 'react-router-redux';
import configureStore from './store/store';
import App from './components/App';
import EULA from './containers/EULA';
import Main from './containers/Main';
import Blog from './containers/Blog';
const store = configureStore();
const history = syncHistoryWithStore(browserHistory, store);
ReactDOM.render(
<Provider store={store}>
<Router history={history}>
<Route path="/" component={App}>
<IndexRoute component={Main} />
<Route path="/main" component={Main} />
<Route path="/Feed" component={Blog} />
<Route path="/Blog" component={Blog} />
<Route path="/EULA" component={EULA} />
</Route>
</Router>
</Provider>,
document.getElementById('app')
);
After working on it to fix the history I ended up with what follows. But when I load the site, the content of the navigation bar (declared in App) is shown, but the sub-content of App (ex: Main, or Blog) is not rendered.
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { Switch, BrowserRouter, Route, IndexRoute } from 'react-router';
import { createBrowserHistory } from 'history';
import {syncHistoryWithStore, push} from 'react-router-redux';
import configureStore from './store/store';
import App from './components/App';
import Main from './containers/Main';
import Blog from './containers/Blog';
import EULA from './containers/EULA';
const store = configureStore();
const history = syncHistoryWithStore(createBrowserHistory(), store);
ReactDOM.render(
<Provider
store={store}>
<Router
history={history}>
<Switch>
<Route exact path="/" component={App} />
<Route path="/main" component={Main} />
<Route path="/Feed" component={Blog} />
<Route path="/Blog" component={Blog} />
<Route path="/EULA" component={EULA} />
<Redirect to="/" />
</Switch>
</Router>
</Provider>,
document.getElementById('app')
);
After further investigations I found this site that describe how to migrate to Router 4.
So I tried it and cannot make the example work.
This is what I have now:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter, Route } from 'react-router';
const PrimaryHeader = props => {
return (
<header>
Our React Router 4 App
</header>
)
}
const HomePage =() => <div>Home Page</div>
const UsersPage = () => <div>Users Page</div>
const UserAddPage = () => <div>Users Add Page</div>
const PrimaryLayout = props => {
return (
<div className="primary-layout">
<PrimaryHeader />
<main>
<Switch>
<Route path="/" exact component={HomePage} />
<Route path="/users/add" component={UserAddPage} />
<Route path="/users" component={UsersPage} />
<Redirect to="/" />
</Switch>
</main>
</div>
)
}
const App = () => (
<BrowserRouter>
<PrimaryLayout />
</BrowserRouter>
)
ReactDOM.render(
<App />,
document.getElementById('app'));
When I compile and get onto the site I see the following in the console:
Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

I have done some further test (using my version that I fixed).
In App render function I was getting the children and rendering them.
Now it seems that children is undefined.
I would venture a guess that it has to do with the fact that in the older version the other routes were children of the "/" {App} route. And that before of the way Router 4 is now it is not the case anymore.
I will have to move children inside main I guess?
But that still does not explain why the simpler example is not working.
It seems like there is something off in your imports. If you delete your node_modules are rerun yarn install (or npm install) the compilation should alert you already.
The following code works fine (and as expected for me)
import React from 'react';
import ReactDOM from 'react-dom';
import {Redirect, Route, Switch} from 'react-router';
import {BrowserRouter} from "react-router-dom";
const PrimaryHeader = props => {
return (
<header>
Our React Router 4 App
</header>
)
};
const HomePage = () => <div>Home Page</div>;
const UsersPage = () => <div>Users Page</div>;
const UserAddPage = () => <div>Users Add Page</div>;
const PrimaryLayout = props => {
return (
<div className="primary-layout">
<PrimaryHeader/>
<main>
<Switch>
<Route path="/" exact component={HomePage}/>
<Route path="/users/add" component={UserAddPage}/>
<Route path="/users" component={UsersPage}/>
<Redirect to="/"/>
</Switch>
</main>
</div>
)
};
const App = () => (
<BrowserRouter>
<PrimaryLayout/>
</BrowserRouter>
);
ReactDOM.render(
<App/>,
document.getElementById('root'));
Changes were:
Import BrowserRouter from react-router-dom
Add missing imports
This was done with react-router 4.2 and react-router-dom 4.2.2
I have a react app setup by dva 2.0.1. In the routers.js, I have:
import React from 'react';
import { Router, Switch, Route, IndexRoute } from 'dva/router';
import IndexPage from './routes/IndexPage'
import CountPage from './routes/CountPage'
function RouterConfig({ history }) {
return (
<Router history={history}>
<Route path="/" component={IndexPage}>
<Switch>
<Route path="/count" component={CountPage}/>
<Route path="/statements" component={CountPage}/>
</Switch>
</Route>
</Router>
);
}
export default RouterConfig;
And in my IndexPage, I have:
import React from 'react';
import { connect } from 'dva';
import styles from './IndexPage.css';
import { Layout } from 'antd'
import Header from '../components/Header'
const { Sider, Content, Footer } = Layout;
const IndexPage = (props) => {
const { children, routes } = props;
console.log(props);
return (
<Layout>
<Header routes={routes}>header</Header>
<Layout>
<Sider>sider</Sider>
<Content>{children || "No content"}</Content>
</Layout>
</Layout>
);
}
IndexPage.propTypes = {
};
export default connect()(IndexPage);
However, the console.log(props); gives dispach, history, etc. But children and routes are not in it.
What happened?
You don't have any child component on your Index component.
If you change this
<Route path="/" component={IndexPage}>
to this
<Route path="/" component={()=>(<IndexPage><p>This is a child component</p></IndexPage>)}>
you can see the child components inside your Index component.
It turns that I was using react-router#2 syntax and should be react-router#4.
I am new to React. I have been trying to declare routes in a file and then use it in another file.
Here is my routes.js
import React from 'react';
import { Route } from 'react-router-dom';
import App from './components/App';
import Template1 from './components/template1';
import Template2 from './components/template2';
import Template3 from './components/template3';
const routes = (
<Route exact path="/" component={App}>
<Route exact path="/sessionstate1" component={Template1} />
<Route exact path="/sessionstate2" component={Template2} />
<Route exact path="/sessionstate3" component={Template3} />
</Route>
)
export default routes
and index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import './styles/css/index.css';
import routes from './routes.js';
ReactDOM.render(
<Router history={browserHistory} routes={routes} />,
document.getElementById('root')
);
I am not getting any errors or warning but the page is not loading. Please tell me what I am missing
Thanks
well i had the same issue a few days ago, and the solution for me was this...
This one of the routes files:
import React from 'react';
import { Route } from 'react-router-dom';
import { ComponentY } from '../components/functionalitys';
export default [
<Route path="/appointment" component={ComponentY} exact key="create" />,
];
This another route file:
import React from 'react';
import { Route } from 'react-router-dom';
import { LoginPage, Register } from '../components/user';
export default [
<Route path="/register" component={Register} exact key="create" />,
<Route path="/login" component={LoginPage} exact strict key="login" />
];
And this is how I imported in the main app.js:
import routesFromFile1 from './the/route';
import routesFromFile2 from './the/other/route';
class App extends Component{
render(){
return(
<div className="wrapper">
<section className="content container-fluid">
<Switch>
<Route exact path="/" component={Home} strict={true} exact={true}/>
<Route path="/500" component={InternalServer} />
{routesFromFile1}
{routesFromFile2}
</Switch>
</section>
</div>
)
}
}
I hope this help Someone! Cheers!!
You don't need to wrap your Routes inside a div. Try something like this:
routes.js
import React from 'react';
import { Router, Route } from 'react-router';
import { Template1, Template2, Template3 } from './templates';
const createRoutes = () => (
<Router>
<Route exact path="/sessionstate1" component={Template1}/>
<Route exact path="/sessionstate2" component={Template2}/>
<Route exact path="/sessionstate3" component={Template3}/>
</Router>
);
export default createRoutes;
index.js
import ReactDOM from 'react-dom';
import createRoutes from './routes';
const routes = createRoutes();
ReactDOM.render(
routes,
document.getElementById('root')
);
index.js:
import LoginRoutes from './login/routes'
let routeConfig = [];
routeConfig = routeConfig.concat(LoginRoutes(store));
<Router routes={routeConfig}/>
routes.js:
export default (store) => {
return [
{path: '/login', component: Login},
{path: '/signup', component: SignUp},
]
}
This way you can add routes from different files and spread your route definitions to different folders that serve the contextual purpose of the route.
The store variable is there in case you want to use redux and want to have an onEnter event on the route. Example:
export default () => {
const sessionEnter = (location) => {
let {appId} = location.params;
store.dispatch(loadApp(appId));
return [
{path: '/apps/:appId', component: App, onEnter: sessionEnter},
]
}
I find onEnter events a good alternative to componentDidMount, data-fetching-wise. Invoking a data fetch on route level makes more sense to me as I see the component as part of the presentation level.
I think the problem is with wrapping the Route inside a div.
Try wrapping them inside a Route like following. Try this fiddle and change the routes wrapper to div.
const routes=(
<Route >
<Route exact path="/sessionstate1" component={Template1}/>
<Route exact path="/sessionstate2" component={Template2}/>
<Route exact path="/sessionstate3" component={Template3}/>
</Route >
)
export default routes;
And import it into index.js
import routes from './routes.js';
ReactDOM.render(
<Router history={browserHistory} routes={routes} />,
document.getElementById('root')
);
With Typescript
Sepate the file for routes as routes.ts
export const routes = [
{ path: '/', component: Home },
{ path: '/auth-callback', component: authCallback },
{ path: '/fetch-data/:startDateIndex?', component: FetchData }
];
In the App.tsx
export function App() {
const routeComponents = routes.map(({ path, component }, key) => <Route exact path={path} component={component} key={key} />);
return (
<Layout>
{routeComponents}
</Layout>
);
}
Layout.tsx
export default (props: { children?: React.ReactNode }) => (
<React.Fragment>
<div>
<NavMenu />
<TopAppBarFixedAdjust>
{props.children}
</TopAppBarFixedAdjust>
</div>
</React.Fragment>
);
I know I'm little late but here my working
here a working demo
my dependencies are
"react": "16.2.0",
"react-dom": "16.2.0",
"react-router-dom": "4.2.2",
"react-scripts": "1.1.0"
create nav.js file as this
this file is responsible for storing all the links for navbar
import React, { Component } from "react";
import { Link } from "react-router-dom";
class Navi extends Component {
render = () => (
<div>
<Link to="/">Go to Home</Link> <br />
<Link to="/about">Go to About</Link> <br />
<Link to="/any-route">404 page</Link>
</div>
);
}
export default Navi;
Then the routes.js file
here you will define all your routes, and your pages where the routes should navigates to
import React, { Component } from "react";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
// your components
const Home = () => <h1>Home</h1>;
const About = () => <h1>About</h1>;
const MissingPage = () => <h1>404</h1>;
const routes = (
<Switch>
<Route path="/" exact component={Home} />
<Route path="/about" component={About} />
<Route component={MissingPage} />
</Switch>
);
export default routes;
finally here is the code for index.js
import React, { Component } from "react";
import ReactDOM from "react-dom";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
import Navi from "./nav";
import routes from "./routes";
// initialize rotues and navi links
const initRoutes = () => (
<Router>
<div>
<Navi />
{routes}
</div>
</Router>
);
const initializedRoutes = initRoutes();
ReactDOM.render(
initializedRoutes,
document.getElementById("root")
);
This is the routing page created
routing page imported
Hope, it will help everyone. click the link to see code.!!
In react-router-dom version 6.x.x
Suppose you have the following URLs in your react app
/
/home
/handlers
/handlers/notes
/handlers/users
you can isolate all routing components related to handlers(including its nested URLs) by:
Define your main routing
<BrowserRouter>
<Routes>
<Route path="/" element={<HomePage />} />
<Route path="/home" element={<HomePage />} />
<Route path="/handlers/*" element={<AllHandlersPages />} />
</Routes>
</BrowserRouter>
Notice the existence of path="/handlers/*" where we have a wildcard * to tell react-router-dom to match with any nested route too
then
declare AllHandlersPages in another file like this
export function AllHandlersPages() {
return (
<Routes>
<Route>
<Route index element={<HandlersIndexPage />} />
<Route path="notes" element={<NotesPage />} />
<Route path="users" element={<UsersPage />} />
</Route>
</Routes>
);
}
Because <Route /> can't be defined unless it has a parent <Routes /> don't forget to make them nested properly.
Full working Demo
Try it like this way
import React from "react";
import {HashRouter as Router, Route} from 'react-router-dom';
import NoteContainer from "./component/note/index.jsx";
import Header from "./component/common/header.jsx";
const App = (props) => {
return (
<div className="container">
<Header/> {props.children}
</div>
);
};
var x = () => {
return (
<h1>Hello world!</h1>
);
};
module.exports = () => {
return (
<Router>
<App>
<Route path="/" component={NoteContainer}/>
<Route path="/inbox" component={x}/>
</App>
</Router>
);
};
I did it with very simple way. Follow the two steps below.
In App.js
import "bootstrap/dist/css/bootstrap.min.css";
import Header from "./component/common/header";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
import routes from "./routes";
function App() {
return (
<Router>
<section className="container">
<Header />
{routes}
</section>
</Router>
);
}
export default App;
in routes.js
import React, { Component } from "react";
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
import Overview from "./component/overview/overview";
import UsersList from "./component/userslist/UsersList";
import FavUserList from "./component/userslist/FavUserList";
const routes = (
<Switch>
<Route exact path="/" component={Overview} />
<Route path="/adduser" component={UsersList} />
<Route path="/favuser" component={FavUserList} />
</Switch>
);
export default routes;
Note: Make sure you import like this
import { BrowserRouter as Router, Route, Link, Switch } from "react-router-dom";
In < Header /> component you have to declare navigation link.
i'm starting into react too, and i figured out a way to make what you are looking for.
What i did was inside the app file (which comes default in every project) i imported the routes file, the routes file is located in a folder called approuter (you can name it whatever you want), i'll write some of my code so you can see what i mean
//APP FILE
import AppRouter from './router/approuter'
function App() {
return (
<>
<div className='app' id="mode">
<AppRouter />
</div>
</>
)
}
export default App
//ROUTER FILE/
import { Route, Routes } from 'react-router-dom'}
import Register from "../pages/register"
import Login from "../pages/login"
export default function AppRouter() {
return (
<>
<div>
<Routes>
<Route path="login" element={<Login />}/>
<Route path="register" element={<Register />}/>
</Routes>
</div>
</>
)
}
This actually worked in a project i'm currently working on, i hope this can answer your question
**index.js**
import ReactDOM from "react-dom/client";
import Paths from "./routes/Paths";
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
<React.StrictMode>
<Paths />
</React.StrictMode>
);
**Paths.js**
import LoginSample from "../portal/LoginSample";
import Dashboard from "../portal/Dashboard";
function Paths() {
return (
<Router>
<Routes>
<Route path="/" element={<LoginSample />} />
<Route path="/dashboard" element={<Dashboard />} />
</Routes>
</Router>
);
}
export default Paths;
Also new to react and was running into the same issue. Here is what I tried (obviously different code and structure, but what we're looking for should be the same functionality)
index.js
import React from "react";
import ReactDOM from "react-dom";
import { createHashHistory } from "history";
import { BrowserRouter, Route } from 'react-router-dom';
import routes from "./routes";
const allRoutes = routes;
ReactDOM.render(
allRoutes,
document.getElementById("app")
)
and the routes.js file.
import React from "react";
import { createHashHistory } from "history";
import { BrowserRouter, Route } from 'react-router-dom';
import App from "./pages/App";
import Detail from "./pages/Detail";
import List from "./pages/List";
const routes = (
<BrowserRouter>
<div>
<Route exact path="/" component={ App } />
<Route path="/" component={ List } />
<Route path="/detail/:repo" component={ Detail } />
</div>
</BrowserRouter>
);
export default routes;
Let me know if that works for you.
