react-breadcrumbs throwing error when using with router - javascript

React Breadcrumbs is throwing some error when using with Router.
I am following this tutorial for implementation.
http://learnreact.robbestad.com/breadcrumbs
Below is the code:
var Breadcrumbs = require('react-breadcrumbs');
const Routes = () => (
<BrowserRouter>
<div>
<Header />
<MegaMenu />
{Breadcrumbs}
<Route exact path='/' name='HomePage' component={HomePage}/>
<Route path='/celebrity' name='Celebrities' component={Celebrities}/>
<Route path='/axios' name='Axios' component={Axios}/>
<Route path='/brands' name='Brands' component={Brands}/>
<Footer />
</div>
</BrowserRouter>
);
export default Routes;
Below is the error:
Objects are not valid as a React child (found: object with keys {Breadcrumb, Breadcrumbs}). If you meant to render a collection of children, use an array instead.

You shouldn't pass the reference directly but use it with React.createElement or in other words, in JSX land you should do just <Breadcrumbs />.
If you look carefully at the code from the link you posted (http://learnreact.robbestad.com/breadcrumbs):
var Breadcrumbs = require('react-breadcrumbs');
MyComponent = React.createClass({
render: function() {
return (
<div>
<Breadcrumbs />{/* You see it here, <Breadcrumbs /> not {Breadcrumbs} */}
</div>
);
}
});
It creates new React element and now let's check your code:
var Breadcrumbs = require('react-breadcrumbs');
const Routes = () => (
<BrowserRouter>
<div>
<Header />
<MegaMenu />
{Breadcrumbs}{/* <-------- Here is the issue */}
<Route exact path='/' name='HomePage' component={HomePage}/>
<Route path='/celebrity' name='Celebrities' component={Celebrities}/>
<Route path='/axios' name='Axios' component={Axios}/>
<Route path='/brands' name='Brands' component={Brands}/>
<Footer />
</div>
</BrowserRouter>
);
export default Routes;
If you replace {Bredcrumbs} with <Breadcrumbs />, it should just work:
var Breadcrumbs = require('react-breadcrumbs');
const Routes = () => (
<BrowserRouter>
<div>
<Header />
<MegaMenu />
<Breadcrumbs />
<Route exact path='/' name='HomePage' component={HomePage}/>
<Route path='/celebrity' name='Celebrities' component={Celebrities}/>
<Route path='/axios' name='Axios' component={Axios}/>
<Route path='/brands' name='Brands' component={Brands}/>
<Footer />
</div>
</BrowserRouter>
);
export default Routes;
You can read more about JSX in the official React documentation:
https://reactjs.org/docs/introducing-jsx.html

I have used this library https://www.npmjs.com/package/react-breadcrumbs-dynamic][1] to implement the breadcrumbs.
Created one route.js and imported the library
import { Breadcrumb as BootstrapBreadcrumb } from 'react-bootstrap'
import { Breadcrumbs, BreadcrumbsItem } from 'react-breadcrumbs-dynamic';
import CrumbItem from '../components/common/breadcrumb/CrumbItem';
Created the breadcrumbs container like this in route.js:
const Routes = () => (
<BrowserRouter>
<div>
<div className="breadcrumbs-container">
<BreadcrumbsItem glyph='home' to={base_path}>
Home Page
</BreadcrumbsItem>
<Breadcrumbs
hideIfEmpty={{ active: true }}
item={CrumbItem}
container={BootstrapBreadcrumb}
finalProps={{ active: true }}
duplicateProps={{ to: 'href' }}
/>
</div>
<Route exact path='/' component={HomePage} />
<Route path='/brands' component={Brands} />
<Footer />
</div>
</BrowserRouter>
);
Given breadcrumbs items in Another component brands.js
import { BreadcrumbsItem } from 'react-breadcrumbs-dynamic';
render() {
return (
<BreadcrumbsItem to={'/brands'}>
Brands
</BreadcrumbsItem>
)
}
Created link container separately
import { Breadcrumb } from 'react-bootstrap'
import { LinkContainer } from 'react-router-bootstrap'
const CrumbItem = ({to, ...props}) => (
<LinkContainer to={to}>
<Breadcrumb.Item {...props}>
</Breadcrumb.Item>
</LinkContainer>
)
export default CrumbItem
Note: Using bootstrap is optional

Render multiple Route into a main Router in react-router-dom v5

I have multiple components with different paths (routes) and would like to export those to a single Main router component.
For example:
routeComponent1.js
export default function childRoutes() {
return (
<div>
<Route path="/foo" component={foo} />
<Route path="/bar" component={bar} />
</div>
);
}
routeComponent2.js
export default function childRoutes2() {
return (
<div>
<Route path="/foo2" component={foo2} />
<Route path="/bar2" component={bar2} />
</div>
);
}
I would like to use it in
root.js
import routeComponent1 from 'routeComponent1.js';
import routeComponent2 from 'routeComponent2.js';
class Root extends Component {
constructor(props) {
super(props);
}
render() {
return <Router>{routeComponent1}</Router>;
}
}
It is giving an error - Invariant Violation: <Route> elements are for router configuration only and should not be rendered.
Expecting the
<Router>
<div>
<Route path="/foo" component={foo} />
<Route path="/bar" component={bar} />
</div>
</Router>
routeComponent1 and routeComponent2 are React components. React components are Capitalized and rendered as JSX.
Example:
import RouteComponent1 from 'routeComponent1.js';
import RouteComponent2 from 'routeComponent2.js';
class Root extends Component {
render() {
return (
<Router>
<RouteComponent1 />
<RouteComponent2 />
</Router>
);
}
}
Assuming you're using the latest version of react router (v6), you can use nested routes as described here: https://reactrouter.com/en/main/start/overview#nested-routes
So this is what your App.jsx might look like:
import {
BrowserRouter as Router, Routes, Route
} from "react-router-dom";
import {AuthRoute, NonAuthRoute, UserParent} from "../components";
import {
Dasboard, UserList, CreateUser, SignIn, Page404
} from "./pages"
// Define your paths here ...
export const paths = {
SIGN_IN: "/sign-in",
DASHBOARD: "/dashboard",
LIST_USERS: "/users/list"
CREATE_USERS: "/users/create"
}
// All your routes which require authentication (requires login)
const authRoutes = [
{
path: paths.DASHBOARD,
element: <Dashboard />
},
]
// Authenticated routes but need a particular parent component
const userAuthRoutes = [
{
path: paths.LIST_USERS,
element: <UserList />
},
{
path: paths.CREATE_USERS,
element: <CreateUser />
}
]
// Paths that dont require authentication
const nonAuthRoutes = [
{
path: paths.SIGN_IN,
element: <SignIn />
},
]
const App = () => {
return (
<Router>
<Routes>
{/* AUTHENTICATED ROUTES */}
<Route element={<AuthRoute />}>
{authRoutes.map((route, index) =>
<Route key={index} {...route} />;
)}
{/* User Management */}
<Route element={<UserParent />}>
{userAuthRoutes.map((route, index) =>
<Route key={index} {...route} />
)}
</Route>
</Route>
{/* NON-AUTH ROUTES */}
<Route element={<NonAuthRoute />}>
{nonAuthRoutes.map((route, index) =>
<Route key={index} {...route} />;
)}
</Route>
<Route path="*" element={<Page404 />} />
</Routes>
</Router>
)
}

How can I split React Router into multiple files

My routes file is getting rather messy so I decided to split them out into separate files.
My problem is that if I used 2 separate files, whichever comes after the first include does not get rendered:
const routes = (
<div>
<Switch>
<Route exact path="/" component={Home} />
{Registration} //Does get rendered
//Everything below this does not get a route
{Faq}
<Route path="/login" component={login} />
<Route component={NoMatch} />
</Switch>
</div>
);
If I switch Faq with registration then all the Faq routes will work.
RegistrationRoutes.js
import Introduction from '../containers/Registration/Introduction';
import Login from '../containers/Login';
const Routes = (
<Switch>
<Route path="/login" component={Login} key="login" />,
<Route path="/registration/introduction" component={Introduction} key="registration-intro" />
</Switch>
);
export default Routes;
FaqRoutes.js
import Faq from '../containers/Faq';
import faqJson from '../json_content/faq/faq';
import FaqCategory from '../containers/Faq/faqCategory';
const Routes = (
<Switch>
<Route path="/faq/:category" component={FaqCategory} key="faqCat" />
<Route path="/faq" render={props => <Faq data={faqJson} />} key="faq" />
</Switch>
);
export default Routes;
May be you can move them to config file and load them from there.
App.tsx
import routes from "./routes";
const App: React.FC = () => {
return (
<BrowserRouter>
<div>
<Switch>
{routes.data.map((entry) => {return (<Route {...entry}/>)})}
</Switch>
</div>
</BrowserRouter>
);
};
export default App;
router.ts
const routes = {data: [
{
key: "one",
path: "/three"
},
{
key: "two",
path: "/two"
}
]
}
export default routes;
This will keep your code simple
Your code would get translated to something like this,
const routes = (
<div>
<Switch>
<Route exact path="/" component={Home} />
<Switch>
<Route path="/login" component={Login} key="login" />,
<Route path="/registration/introduction"
component={Introduction} key="registration-intro" />
</Switch>
//Everything below this does not get a route
{Faq}
<Route path="/login" component={login} />
<Route component={NoMatch} />
</Switch>
</div>
);
This is wrong way to implement routing with react-router-dom or React-Router v4.
For Correct way of implementation You can see this example.
index.js
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter, Switch, Route, Link } from "react-router-dom";
import LandingPage from "../Registration";
const Home = () => {
return <div>
Home Component
<Link to="/auth/login">Login</Link>
</div>;
};
function App() {
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<BrowserRouter>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/auth" component={LandingPage} />
</Switch>
</BrowserRouter>
</div>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
Registration.js
import React, { Component } from 'react';
import { Switch, Route, Link, Redirect } from 'react-router-dom';
const LoginRegister = (props) => {
return (
<div>
Login or register
<Link to="/login">Login</Link>
<br />
<Link to="/signup" >Signup</Link>
</div>
);
}
const Login = (props) =>{
console.log("login ", props);
return (
<div>
Login Component
<Link to="/auth/signup" >Signup</Link>
</div>
);
}
const Signup = () => (
<div>
Signup component
<Link to="/auth/login" >Login</Link>
</div>
);
class LandingPage extends Component {
render() {
console.log('Landing page',this.props);
const loginPath = this.props.match.path +'/login';
const signupPath = this.props.match.path + '/signup';
console.log(loginPath);
return (
<div className="container" >
Landing page
<Switch>
<Route path={loginPath} component={Login} />
<Route path={signupPath} component={Signup} />
<Route path="/" exact component={LoginRegister} />
</Switch>
</div>
);
}
}
export default LandingPage;
Try the following
RegistrationRoutes.js
import Introduction from '../containers/Registration/Introduction';
import Login from '../containers/Login';
const Routes = (
<React.Fragment>
<Route path="/login" component={Login} key="login" />,
<Route path="/registration/introduction" component={Introduction} key="registration-intro" />
</React.Fragment>
);
export default Routes;

React router dom and layouts

I want to use layouts with my react-router-dom, at this moment i am doing that like this
const DefaultLayout = ({children, ...rest}) => {
return (
<div className={styles.wrapper}>
<Header/>
{children}
<Footer/>
</div>
)
};
const DefaultRoute = ({component: Component, ...rest}) => {
return (
<Route {...rest} render={matchProps => (
<DefaultLayout>
<Component {...matchProps} />
</DefaultLayout>
)}/>
)
};
render(
<Provider store={store}>
<HashRouter>
<Switch>
<DefaultRoute exact path="/" component={AdvertList}/>
<DefaultRoute exact path="/user" component={UserOptions}/>
<Route path="/login" children={Login}/>
<Route render={
() => (
<div>
Not found
</div>
)
}/>
</Switch>
</HashRouter>
</Provider>,
document.querySelector('#app')
);
it works okay, both UserOptions and AdvertList components are rendered inside DefaultLayout, and Login component does not, but in official documentation i didn't find solution like that, instead there is "nested routing" where you adding new nested routes in subclasses, like
if you need default layout u make it on route /, then if you need advert list with that layout, in layout component you defined route /adverts and adding link to it, and so on, each sub component uses layout of parent one.
But in my case there is already product list on route /, and i need to change that content to other products list regarding link pressed, not to add to parent layout, but to change it part. Here is my code,
const { BrowserRouter, Route, Switch, Link } = window.ReactRouterDOM;
const { Component } = window.React;
const About = () => ('About');
const MiscProducts = () => ('Misc products');
class AdvertsList extends Component {
render() {
return (
<div className="container">
<header>Header</header>
<main>
<nav>
<Link to="/miscProducts">Misc Products</Link> #
<Link to="/about">About</Link>
</nav>
<div className="content">
Main Products
</div>
</main>
<footer>Footer</footer>
<Route path="/miscProducts" component={MiscProducts} />
</div>
)
};
};
class App extends Component {
render() {
return (
<BrowserRouter>
<Switch>
<Route path="/" component={AdvertsList} />
<Route path="/about" component={About} />
<Route path="*" render={
() => (
<div>
Not found
</div>
)
}/>
</Switch>
</BrowserRouter>
);
}
}
ReactDOM.render(<App />, document.querySelector("#app"));
http://jsfiddle.net/gmcke2a4/6/ here main products loaded by default, and when i press misc products, misc products must be loaded instead of main one.
p.s. And why about doesn't work?
Login Fix
<Route path="/login" children={Login}/> this seems wrong because children component expects function which return nodes i think.Try <Route path="/login" children={() => (</Login />)}
Layout
But in my case there is already product list on route /, and i need to
change that content to other products list regarding link pressed, not
to add to parent layout
You can create component which renders specific products like this.
const MainProducts = () => 'Main Products'
const GummyBearsProducts = () => 'GummyBears'
const Products = props => (
<div className="products-container">
<Switch>
<Route path={`${props.location.pathname}`} component={MainProducts}/>
<Route path={`${props.location.pathname}/gummy-bears`} components={GummyBearProducts}/>
</Switch>
</div>
)
And then use it as follows.
class AdvertsList extends Component {
render() {
return (
<div className="container">
<header>Header</header>
<main>
<nav>
<Link to="/products">Products</Link> #
<Link to="/about">About</Link>
</nav>
<div className="content">
<Route path="/products" component={Products} />
</div>
</main>
<footer>Footer</footer>
</div>
)
};
};
React router is great in rendering specific components.I hope it answers your question.Cheers!
If you are using react-router-dom v6. Then follow the below procedure to configure react-router-dom,
App.jsx:
import './App.css';
import { BrowserRouter, Routes, Route } from 'react-router-dom'
import Home from './Components/Home'
import About from './Components/About'
import Layout from './Components/Layout'
function App() {
return (
<div className="App">
<BrowserRouter>
<Routes>
<Route path="/" element={<Layout />}>
<Route path="/" element={<Home />} />
<Route path="about" element={<About />} />
</Route>
</Routes>
</BrowserRouter>
</div>
);
}
export default App;
After configuring the react router in App.jsx. I am creating 3 components Home, About and Layout. Home and About are regular components and Layout component is to handle the Layout part in react-router-dom using Outlet.
Layout.jsx
import { Outlet, Link } from 'react-router-dom'
export default function Layout() {
return (
<>
<Link to="/">Home</Link>
<Link to="/about">About</Link>
<Outlet />
</>
)
}
Home.jsx
export default function Home() {
return (
<>
<p>This is Home</p>
</>
)
}
About.jsx
export default function About() {
return (
<>
<p>This is About Us</p>
</>
)
}

React Router - trigger file download

How to skip the react routing in case of file paths? It seems react router intercepts all links. Example below - the hardcoded link /1.pdf seems to trigger the router.
How do we trigger file downloads?
const Main = () => {
return (
<div>
<h1>React Router Playground</h1>
<Link to="/download">Download Area</Link>
</div>
);
};
const Download = () => {
return (
<div>
<h1>Download Area</h1>
Download
</div>
);
};
export default class App extends React.Component {
constructor(props) {
super(props);
this.state = {};
}
render() {
return (
<Router>
<div>
<Route exact path="/" component={Main} />
<Route path="/download" component={Download} />
</div>
</Router>
);
}
}
This is a rather simple example so the hardcoded link. These are dynamic and passed as props in the actual code.
The following code combined with a NoMatch component should work, reloading the URL if it's a valid resource.
<Router>
<div>
<Switch>
<Route exact path="/" component={Main} />
<Route exact path="/download" component={Download} />
<Route component={NoMatch} />
<Route onEnter={() => window.location.reload()} />
</Switch>
</div>
</Router>

Nested routes with react router v4 / v5

I am currently struggling with nesting routes using react router v4.
The closest example was the route config in the
React-Router v4 Documentation.
I want to split my app in 2 different parts.
A frontend and an admin area.
I was thinking about something like this:
<Match pattern="/" component={Frontpage}>
<Match pattern="/home" component={HomePage} />
<Match pattern="/about" component={AboutPage} />
</Match>
<Match pattern="/admin" component={Backend}>
<Match pattern="/home" component={Dashboard} />
<Match pattern="/users" component={UserPage} />
</Match>
<Miss component={NotFoundPage} />
The frontend has a different layout and style than the admin area. So within the frontpage the route home, about and so one should be the child routes.
/home should be rendered into the Frontpage component and /admin/home should be rendered within the Backend component.
I tried some other variations but I always ended in not hitting /home or /admin/home.
Final solution:
This is the final solution I am using right now. This example also has a global error component like a traditional 404 page.
import React, { Component } from 'react';
import { Switch, Route, Redirect, Link } from 'react-router-dom';
const Home = () => <div><h1>Home</h1></div>;
const User = () => <div><h1>User</h1></div>;
const Error = () => <div><h1>Error</h1></div>
const Frontend = props => {
console.log('Frontend');
return (
<div>
<h2>Frontend</h2>
<p><Link to="/">Root</Link></p>
<p><Link to="/user">User</Link></p>
<p><Link to="/admin">Backend</Link></p>
<p><Link to="/the-route-is-swiggity-swoute">Swiggity swooty</Link></p>
<Switch>
<Route exact path='/' component={Home}/>
<Route path='/user' component={User}/>
<Redirect to={{
state: { error: true }
}} />
</Switch>
<footer>Bottom</footer>
</div>
);
}
const Backend = props => {
console.log('Backend');
return (
<div>
<h2>Backend</h2>
<p><Link to="/admin">Root</Link></p>
<p><Link to="/admin/user">User</Link></p>
<p><Link to="/">Frontend</Link></p>
<p><Link to="/admin/the-route-is-swiggity-swoute">Swiggity swooty</Link></p>
<Switch>
<Route exact path='/admin' component={Home}/>
<Route path='/admin/user' component={User}/>
<Redirect to={{
state: { error: true }
}} />
</Switch>
<footer>Bottom</footer>
</div>
);
}
class GlobalErrorSwitch extends Component {
previousLocation = this.props.location
componentWillUpdate(nextProps) {
const { location } = this.props;
if (nextProps.history.action !== 'POP'
&& (!location.state || !location.state.error)) {
this.previousLocation = this.props.location
};
}
render() {
const { location } = this.props;
const isError = !!(
location.state &&
location.state.error &&
this.previousLocation !== location // not initial render
)
return (
<div>
{
isError
? <Route component={Error} />
: <Switch location={isError ? this.previousLocation : location}>
<Route path="/admin" component={Backend} />
<Route path="/" component={Frontend} />
</Switch>}
</div>
)
}
}
class App extends Component {
render() {
return <Route component={GlobalErrorSwitch} />
}
}
export default App;
In react-router-v4 you don't nest <Routes />. Instead, you put them inside another <Component />.
For instance
<Route path='/topics' component={Topics}>
<Route path='/topics/:topicId' component={Topic} />
</Route>
should become
<Route path='/topics' component={Topics} />
with
const Topics = ({ match }) => (
<div>
<h2>Topics</h2>
<Link to={`${match.url}/exampleTopicId`}>
Example topic
</Link>
<Route path={`${match.path}/:topicId`} component={Topic}/>
</div>
)
Here is a basic example straight from the react-router documentation.
react-router v6
Update for 2022 - v6 has nested Route components that Just Work™.
This question is about v4/v5, but the best answer now is just use v6 if you can!
See example code in this blog post. If you can't upgrade just yet, however...
react-router v4 & v5
It's true that in order to nest Routes you need to place them in the child component of the Route.
However if you prefer a more inline syntax rather than breaking your Routes up across components, you can provide a functional component to the render prop of the Route you want to nest under.
<BrowserRouter>
<Route path="/" component={Frontpage} exact />
<Route path="/home" component={HomePage} />
<Route path="/about" component={AboutPage} />
<Route
path="/admin"
render={({ match: { url } }) => (
<>
<Route path={`${url}/`} component={Backend} exact />
<Route path={`${url}/home`} component={Dashboard} />
<Route path={`${url}/users`} component={UserPage} />
</>
)}
/>
</BrowserRouter>
If you're interested in why the render prop should be used, and not the component prop, it's because it stops the inline functional component from being remounted on every render. See the documentation for more detail.
Note the example wraps the nested Routes in a Fragment. Prior to React 16, you can use a container <div> instead.
Just wanted to mention react-router v4 changed radically since this question was posted/answed.
There is no <Match> component any more! <Switch>is to make sure only the first match is rendered. <Redirect> well .. redirects to another route. Use or leave out exact to either in- or exclude a partial match.
See the docs. They are great. https://reacttraining.com/react-router/
Here's an example I hope is useable to answer your question.
<Router>
<div>
<Redirect exact from='/' to='/front'/>
<Route path="/" render={() => {
return (
<div>
<h2>Home menu</h2>
<Link to="/front">front</Link>
<Link to="/back">back</Link>
</div>
);
}} />
<Route path="/front" render={() => {
return (
<div>
<h2>front menu</h2>
<Link to="/front/help">help</Link>
<Link to="/front/about">about</Link>
</div>
);
}} />
<Route exact path="/front/help" render={() => {
return <h2>front help</h2>;
}} />
<Route exact path="/front/about" render={() => {
return <h2>front about</h2>;
}} />
<Route path="/back" render={() => {
return (
<div>
<h2>back menu</h2>
<Link to="/back/help">help</Link>
<Link to="/back/about">about</Link>
</div>
);
}} />
<Route exact path="/back/help" render={() => {
return <h2>back help</h2>;
}} />
<Route exact path="/back/about" render={() => {
return <h2>back about</h2>;
}} />
</div>
</Router>
Hope it helped, let me know. If this example is not answering your question well enough, tell me and I'll see if I can modify it.
I succeeded in defining nested routes by wrapping with Switch and define nested route before than root route.
<BrowserRouter>
<Switch>
<Route path="/staffs/:id/edit" component={StaffEdit} />
<Route path="/staffs/:id" component={StaffShow} />
<Route path="/staffs" component={StaffIndex} />
</Switch>
</BrowserRouter>
Reference: https://github.com/ReactTraining/react-router/blob/master/packages/react-router/docs/api/Switch.md
Using Hooks
The latest update with hooks is to use useRouteMatch.
Main routing component
export default function NestingExample() {
return (
<Router>
<Switch>
<Route path="/topics">
<Topics />
</Route>
</Switch>
</Router>
);
}
Child component
function Topics() {
// The `path` lets us build <Route> paths
// while the `url` lets us build relative links.
let { path, url } = useRouteMatch();
return (
<div>
<h2>Topics</h2>
<h5>
<Link to={`${url}/otherpath`}>/topics/otherpath/</Link>
</h5>
<ul>
<li>
<Link to={`${url}/topic1`}>/topics/topic1/</Link>
</li>
<li>
<Link to={`${url}/topic2`}>/topics/topic2</Link>
</li>
</ul>
// You can then use nested routing inside the child itself
<Switch>
<Route exact path={path}>
<h3>Please select a topic.</h3>
</Route>
<Route path={`${path}/:topicId`}>
<Topic />
</Route>
<Route path={`${path}/otherpath`>
<OtherPath/>
</Route>
</Switch>
</div>
);
}
Some thing like this.
import React from 'react';
import {
BrowserRouter as Router, Route, NavLink, Switch, Link
} from 'react-router-dom';
import '../assets/styles/App.css';
const Home = () =>
<NormalNavLinks>
<h1>HOME</h1>
</NormalNavLinks>;
const About = () =>
<NormalNavLinks>
<h1>About</h1>
</NormalNavLinks>;
const Help = () =>
<NormalNavLinks>
<h1>Help</h1>
</NormalNavLinks>;
const AdminHome = () =>
<AdminNavLinks>
<h1>root</h1>
</AdminNavLinks>;
const AdminAbout = () =>
<AdminNavLinks>
<h1>Admin about</h1>
</AdminNavLinks>;
const AdminHelp = () =>
<AdminNavLinks>
<h1>Admin Help</h1>
</AdminNavLinks>;
const AdminNavLinks = (props) => (

React Router v6
allows to use both nested routes (like in v3) and separate, splitted routes (v4, v5).
Nested Routes
Keep all routes in one place for small/medium size apps:
<Routes>
<Route path="/" element={<Home />} >
<Route path="user" element={<User />} />
<Route path="dash" element={<Dashboard />} />
</Route>
</Routes>
const App = () => {
return (
<BrowserRouter>
<Routes>
// /js is start path of stack snippet
<Route path="/js" element={<Home />} >
<Route path="user" element={<User />} />
<Route path="dash" element={<Dashboard />} />
</Route>
</Routes>
</BrowserRouter>
);
}
const Home = () => {
const location = useLocation()
return (
<div>
<p>URL path: {location.pathname}</p>
<Outlet />
<p>
<Link to="user" style={{paddingRight: "10px"}}>user</Link>
<Link to="dash">dashboard</Link>
</p>
</div>
)
}
const User = () => <div>User profile</div>
const Dashboard = () => <div>Dashboard</div>
ReactDOM.render(<App />, document.getElementById("root"));
<div id="root"></div>
<script src="https://unpkg.com/react#16.13.1/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16.13.1/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/history#5.0.0/umd/history.production.min.js"></script>
<script src="https://unpkg.com/react-router#6.0.0-alpha.5/umd/react-router.production.min.js"></script>
<script src="https://unpkg.com/react-router-dom#6.0.0-alpha.5/umd/react-router-dom.production.min.js"></script>
<script>var { BrowserRouter, Routes, Route, Link, Outlet, useNavigate, useLocation } = window.ReactRouterDOM;</script>
Alternative: Define your routes as plain JavaScript objects via useRoutes.
Separate Routes
You can use separates routes to meet requirements of larger apps like code splitting:
// inside App.jsx:
<Routes>
<Route path="/*" element={<Home />} />
</Routes>
// inside Home.jsx:
<Routes>
<Route path="user" element={<User />} />
<Route path="dash" element={<Dashboard />} />
</Routes>
const App = () => {
return (
<BrowserRouter>
<Routes>
// /js is start path of stack snippet
<Route path="/js/*" element={<Home />} />
</Routes>
</BrowserRouter>
);
}
const Home = () => {
const location = useLocation()
return (
<div>
<p>URL path: {location.pathname}</p>
<Routes>
<Route path="user" element={<User />} />
<Route path="dash" element={<Dashboard />} />
</Routes>
<p>
<Link to="user" style={{paddingRight: "5px"}}>user</Link>
<Link to="dash">dashboard</Link>
</p>
</div>
)
}
const User = () => <div>User profile</div>
const Dashboard = () => <div>Dashboard</div>
ReactDOM.render(<App />, document.getElementById("root"));
<div id="root"></div>
<script src="https://unpkg.com/react#16.13.1/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16.13.1/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/history#5.0.0/umd/history.production.min.js"></script>
<script src="https://unpkg.com/react-router#6.0.0-alpha.5/umd/react-router.production.min.js"></script>
<script src="https://unpkg.com/react-router-dom#6.0.0-alpha.5/umd/react-router-dom.production.min.js"></script>
<script>var { BrowserRouter, Routes, Route, Link, Outlet, useNavigate, useLocation } = window.ReactRouterDOM;</script>
You can try something like
Routes.js
import React, { Component } from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom';
import FrontPage from './FrontPage';
import Dashboard from './Dashboard';
import AboutPage from './AboutPage';
import Backend from './Backend';
import Homepage from './Homepage';
import UserPage from './UserPage';
class Routes extends Component {
render() {
return (
<div>
<Route exact path="/" component={FrontPage} />
<Route exact path="/home" component={Homepage} />
<Route exact path="/about" component={AboutPage} />
<Route exact path="/admin" component={Backend} />
<Route exact path="/admin/home" component={Dashboard} />
<Route exact path="/users" component={UserPage} />
</div>
)
}
}
export default Routes
App.js
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
import { BrowserRouter as Router, Route } from 'react-router-dom'
import Routes from './Routes';
class App extends Component {
render() {
return (
<div className="App">
<Router>
<Routes/>
</Router>
</div>
);
}
}
export default App;
I think you can achieve the same from here also.
A complete answer for React Router v5.
const Router = () => {
return (
<Switch>
<Route path={"/"} component={LandingPage} exact />
<Route path={"/games"} component={Games} />
<Route path={"/game-details/:id"} component={GameDetails} />
<Route
path={"/dashboard"}
render={({ match: { path } }) => (
<Dashboard>
<Switch>
<Route
exact
path={path + "/"}
component={DashboardDefaultContent}
/>
<Route path={`${path}/inbox`} component={Inbox} />
<Route
path={`${path}/settings-and-privacy`}
component={SettingsAndPrivacy}
/>
<Redirect exact from={path + "/*"} to={path} />
</Switch>
</Dashboard>
)}
/>
<Route path="/not-found" component={NotFound} />
<Redirect exact from={"*"} to={"/not-found"} />
</Switch>
);
};
export default Router;
const Dashboard = ({ children }) => {
return (
<Grid
container
direction="row"
justify="flex-start"
alignItems="flex-start"
>
<DashboardSidebarNavigation />
{children}
</Grid>
);
};
export default Dashboard;

I prefer to use react function. This solution is short and more readable
const MainAppRoutes = () => (
<Switch>
<Route exact path='/' component={HomePage} />
{AdminRoute()}
{SampleRoute("/sample_admin")}
</Switch>
);
/*first implementation: without params*/
const AdminRoute = () => ([
<Route path='/admin/home' component={AdminHome} />,
<Route path='/admin/about' component={AdminAbout} />
]);
/*second implementation: with params*/
const SampleRoute = (main) => ([
<Route path={`${main}`} component={MainPage} />,
<Route path={`${main}/:id`} component={MainPage} />
]);
**This code worked for me with v6**
index.js
ReactDOM.render(
<React.StrictMode>
<BrowserRouter>
<Routes>
<Route path="/" element={<App />}>
<Route path="login" element={<Login />} />
<Route path="home" element={<Home />} />
</Route>
</Routes>
</BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);
App.js:
function App(props) {
useEffect(() => {
console.log('reloaded');
// Checking, if Parent component re-rendering or not *it should not be, in the sense of performance*, this code doesn't re-render parent component while loading children
});
return (
<div className="App">
<Link to="login">Login</Link>
<Link to="home">Home</Link>
<Outlet /> // This line is important, otherwise we will be shown with empty component
</div>
);
}
login.js:
const Login = () => {
return (
<div>
Login Component
</div>
)
};
home.js:
const Home= () => {
return (
<div>
Home Component
</div>
)
};
interface IDefaultLayoutProps {
children: React.ReactNode
}
const DefaultLayout: React.SFC<IDefaultLayoutProps> = ({children}) => {
return (
<div className="DefaultLayout">
{children}
</div>
);
}
const LayoutRoute: React.SFC<IDefaultLayoutRouteProps & RouteProps> = ({component: Component, layout: Layout, ...rest}) => {
const handleRender = (matchProps: RouteComponentProps<{}, StaticContext>) => (
<Layout>
<Component {...matchProps} />
</Layout>
);
return (
<Route {...rest} render={handleRender}/>
);
}
const ScreenRouter = () => (
<BrowserRouter>
<div>
<Link to="/">Home</Link>
<Link to="/counter">Counter</Link>
<Switch>
<LayoutRoute path="/" exact={true} layout={DefaultLayout} component={HomeScreen} />
<LayoutRoute path="/counter" layout={DashboardLayout} component={CounterScreen} />
</Switch>
</div>
</BrowserRouter>
);
