I need to set a switch that shows containers components and a login form when the user is not authenticated on each of the main component.
I found another solution that tells you to wrap two components inside a div to use it in the same path inside a switch. But the problem is that some of my components use a req.params from the path that are not passed to the components when they're wrapped in a div
function Routes(props) {
const noLoggedIn = [
{
path: "/",
exact: true,
component: () => <div>
<EventsListContainer />
<LoginFormContainer />
</div>
},
{
path: "/events/:id",
exact: false,
component: () => <div>
//when the component is mounted it doesn't get the :id
<EventDetailsContainer />
<LoginFormContainer />
</div>
}
]
return (<div>
{!props.authenticated &&
<Switch>
{noLoggedIn.map((route, index) =>
<Route
key={index}
path={route.path}
exact={route.exact}
component={route.component}
/>
)}
</Switch>}
{props.authenticated &&
<Switch>
<Route exact path="/" component={EventsListContainer} />
<Route exact path="/" component={CreateEventFormContainer} />
//here the component gets the :id
<Route path="/events/:id" component={EventDetailsContainer} />
<Route path="/events/:id" component={CreateTicketFormContainer} />
</Switch> }
</div>)
}
Try as follows -
<Route path='/some-path' render={props =>
<div>
<FirstChild />
<SecondChild />
</div>
} />
you can also do it like as follows -
render((
<Router>
<Route path="/" component={App}>
<Route path="groups" components={{main: Groups, sidebar: GroupsSidebar}} />
<Route path="users" components={{main: Users, sidebar: UsersSidebar}}>
<Route path="users/:userId" component={Profile} />
</Route>
</Route>
</Router>
), node)
class App extends React.Component {
render() {
// the matched child route components become props in the parent
return (
<div>
<div className="Main">
{/* this will either be <Groups> or <Users> */}
{this.props.main}
</div>
<div className="Sidebar">
{/* this will either be <GroupsSidebar> or <UsersSidebar> */}
{this.props.sidebar}
</div>
</div>
)
}
}
class Users extends React.Component {
render() {
return (
<div>
{/* if at "/users/123" this will be <Profile> */}
{/* UsersSidebar will also get <Profile> as this.props.children.
You can pick where it renders */}
{this.props.children}
</div>
)
}
}

I was refactoring my React app after updating React Router to v6 and I got rid of the error I was getting in my routes, except now the desired layout is broken.
I need to include a permanent toolbar and a sidebar to be visible only in some pages. I tried to follow the docs but now the layout component is placed above all the pages it should be wrapping, not just overlapping them, but actually concealing them behind it.
The Layout component:
function Layout({ children }) {
return (
<div className="layout">
<Header />
<SidePanel />
<div className="main" style={{ marginTop: "100px" }}>
{children}
</div>
</div>
);
}
export default Layout;
The AppRouter component:
function AppRouter() {
return (
<Router>
<Routes>
<Route path="/" exact element={<Home />} />
<Route path="/login" element={<Login />} />
<Route path="/sign-up" element={<SignUp />} />
<Route element={<Layout />}>
<Route path="/diary" element={<Diary />} />
<Route path="/results" element={<Results />} />
<Route path="/details" element={<Details />} />
<Route path="/about" element={<About />} />
</Route>
</Routes>
</Router>
);
}
export default AppRouter;
Layout should render an Outlet for the children Routes to be rendered into.
import { Outlet } from 'react-router-dom';
function Layout() {
return (
<div className="layout">
<Header />
<SidePanel />
<div className="main" style={{ marginTop: "100px" }}>
<Outlet />
</div>
</div>
);
}
Outlet
An <Outlet> should be used in parent route elements to render their
child route elements. This allows nested UI to show up when child
routes are rendered.
I'm building a winery themed shopping app in React and I'm using functional components. I have 12 products (wines) displayed on one page, and I want to make a separate page for each wine when the user clicks on it.
This is how I handled routes:
<BrowserRouter>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/products" element={<Products wines={products}/>} />
<Route path="/contact" element={<Contact />} />
<Route path="/cart" element={<Cart />} />
{wines.map((wine) => (
<Route key={wine.id} path={`/shop/${wine.id}`} element={<Item item={wine} />}/>
))}
</Routes>
</BrowserRouter>
I mapped through all of the wines and created a separate route for each of them, and sent a particular wine as a prop to each "Item" component.
Item component looks like this:
const Item = (item) => {
return (
<>
<Header />
<div className="item_container">
<img className="item_image" alt={item.name} src={item.image} />
<h1 className="item_name">{item.name}</h1>
<h3 className="item_price">{item.price}</h3>
</div>
<Footer />
</>
)
When I console log "item" in this component, I get the specific wine and I can see all of its attributes (name, price, image URL), but when I try to access those attributes in order to display them (item.name, item.image, item.price), the console logs "undefined".
How can i fix this?
You've passed a item prop to the Item component.
<Item item={wine} />
And then named the props object item in the Item component.
const Item = (item) => { ... }
Either rename to props and correctly access props.item.xxx
const Item = (props) => {
const { item } = props;
return (
<>
<Header />
<div className="item_container">
<img className="item_image" alt={item.name} src={item.image} />
<h1 className="item_name">{item.name}</h1>
<h3 className="item_price">{item.price}</h3>
</div>
<Footer />
</>
);
}
or destructure item directly
const Item = ({ item }) => (
<>
<Header />
<div className="item_container">
<img className="item_image" alt={item.name} src={item.image} />
<h1 className="item_name">{item.name}</h1>
<h3 className="item_price">{item.price}</h3>
</div>
<Footer />
</>
);
An optimization I'd suggest is to declare a single route with the wine id as a route path param, and then access the wines array in Item.
Example:
<BrowserRouter>
<Routes>
<Route path="/" element={<Home />} />
<Route path="/products" element={<Products wines={products}/>} />
<Route path="/contact" element={<Contact />} />
<Route path="/cart" element={<Cart />} />
<Route path="/shop/:wineId" element={<Item />} />
</Routes>
</BrowserRouter>
...
import { useParams } from 'react-router-dom';
const Item = () => {
const { wineId } = useParams();
const wine = wines.find(wine => wine.id === wineId);
if (!wine) return <div>No wine found.</div>;
return (
<>
<Header />
<div className="item_container">
<img className="item_image" alt={wine.name} src={wine.image} />
<h1 className="item_name">{wine.name}</h1>
<h3 className="item_price">{wine.price}</h3>
</div>
<Footer />
</>
);
}
Please check null and empty array for "wines" first , if not null then map through "wines"

How to navigate through the tabs in react.
Since I am currently in a tab, I have already used react route and the nested route does not work. how to make a transition through the masonry. Through a nested route or otherwise?
I have a react application inside this I have component with my routers
export const Container = (props) => {
return (
<Switch>
<Route exact path="/">
<Redirect to={PERSONAL} />
</Route>
<Route path={PAGE} render={() => <PicturesMainPage />} />
<Route path={PERSONAL} render={() => <PersonalPage />} />
<Route path={PERSONAL_SETTINGS} render={() => <PersonalSettingsPage />} />
</Switch>
);
};
In this component I have inside this component I drow an information about user with menu and i wand to drow athother components for click in to menu
export const PersonalPage = () => {
return (
<div className="container">
<PersonalInfo />
<div className="personal-area__galery">
<Switch>
<Route exact path={PERSONAL}>
<Redirect to={PERSONAL_GALLERY} />
</Route>
<Route path={PERSONAL_GALLERY} render={() => <Gallery images={images} />} />
<Route path={PERSONAL_COLLECTIONS} render={() => <Collections />} />
<Route path={PERSONAL_STATISTICS} render={() => <Statistics />} />
</Switch>
</div>
</div>
);
};
Person info
let menu = [
{ href: PERSONAL_GALLERY, text: 'Галерея' },
{ href: PERSONAL_COLLECTIONS, text: 'Коллекции' },
{ href: '/personal/statistics', text: 'Статистика' },
];
let person = {
profileName: 'Top Waifu',
profileTag: '#topwaifu',
profileDescription: 'Самая топовая вайфу твоего района',
subscribers: '5.1m',
subscriptions: 246,
};
export const PersonalInfo = (props) => {
return (
<div>
<div className="personal-area__profile">

<MenuElement key={i} menulink={elem.href} menuName={elem.text} />
))}
</ul>
</div>
</div>
);
};
take a look at this codesandbox I made.
https://codesandbox.io/s/frosty-cdn-1fn0u?file=/src/App.js
Here you can see a clear example of nesting routes.
Currently using ReactJS to construct a small web app. I have the following parent function:
const Main = () => {
return (
<div className="dialog-base">
<BrowserRouter>
<Switch>
<Route exact path="/login" component={Login}></Route>
<Route exact path="/login/forgot_password" component={ForgotPwd}></Route>
<Route exact path="/login/reset_password/:key" component={ResetPwd}></Route>
<Route exact path="/portal" component={Portal}></Route>
</Switch>
</BrowserRouter>
</div>
);
}
and the following is the "Portal" component:
class Portal extends React.Component {
render = () => {
return (
<BrowserRouter basename="/main">
<div className="navmenu">
<NavLink to="messaging" activeClassName="selected">Messaging</NavLink>
<NavLink to="files" activeClassName="selected"></NavLink>
<NavLink to="payledger" activeClassName="selected"></NavLink>
</div>
<div className="apparea">
<Switch>
<Route path="/messaging" component={Messaging}></Route>
<Route path="/files" component={Files}></Route>
<Route path="/payledger" component={PayLedger}></Route>
</Switch>
</div>
</BrowserRouter>
);
}
}
When the portal component is loaded and I refresh the web page, the page goes blank. I am assuming that this has something to do with the nested routing? Any help on how to fix it would be much appreciated.
You don't need two <BrowserRouter />. Just define one <BrowserRouter /> in your top level component.
In react-router-dom v4+ the <Route /> is just like a regular component and you can use it inside your components to render UI when the path matches the URL.
Here is the working codesandbox example.
Make sure not to put exact on your parent <Route /> because when you have child routes like /main/messaging the <Route exact path="/main" /> never gets to render and therefore children of that route can't be rendered also.
You keep your <Main /> component as is but remove the exact from the <Route path='/portal' /> and change the <Portal />.
class Portal extends React.Component {
render = () => {
return (
<React.Fragment>
<div className="navmenu">
<NavLink to="/portal/messaging" activeClassName="selected">Messaging</NavLink>
<NavLink to="/portal/files" activeClassName="selected"></NavLink>
<NavLink to="/portal/payledger" activeClassName="selected"></NavLink>
</div>
<div className="apparea">
<Switch>
<Route path="/portal/messaging" component={Messaging}></Route>
<Route path="/portal/files" component={Files}></Route>
<Route path="/portal/payledger" component={PayLedger}></Route>
</Switch>
</div>
</React.Fragment>
);
}
}
Route.js
const Layout = () => {
const SecuredRoute = ({ ...props }) => (
console.log(props.path),
<Route path={props.path} render={(data) => (
console.log(data),
localStorage.getItem('accessToken')
? <props.render {...data} />
: <Redirect to='/login' />
)} />
)
return (
<>
<BrowserRouter>
<Navbar /> // It needs to be hidden if user is not logged in
<div className='layout'>
<Switch>
<Route exact path='/home' component={Home} />
<Route exact path='/login' component={Login} />
<SecuredRoute exact path='/about' component={About} />
<Route exact path='/contact' component={Contact} />
<Route exact path='/add' component={AddBlog} />
<Route exact path='/edit/:id' component={UpdateBlog} />
<Route exact path='/blog/:id' component={Blogdetail} />
<Route component={Home} />
</Switch>
</div>
<Footer />
</BrowserRouter>
</>
)
}
export default Layout
I want if the user is not logged in then navbar must be hidden. It means when route = '/login' navbar needs to be hidden. u have tried out many things but nothing works. I am new to React. Any help will be appreciated?
You can create a boolean variable and short-circuit it.
render() {
const visible = true;
const notVisible = false;
return (
<div>
{visible && <p>I am visible</p>}
{notVisible && <p>I am not visible</p>}
</div>
);
}
Try this in the Navbar component my friend:
const [loggedIn, setLoggedIn] = useState(false);
const Layout = () => {
const SecuredRoute = ({ ...props }) => (
console.log(props.path),
<Route path={props.path} render={(data) => (
console.log(data),
localStorage.getItem('accessToken')
? <props.render {...data} />
: <Redirect to='/login' />
)} />
)
return (
<>
<BrowserRouter>
<Navbar loggedIn={loggedIn} /> // It needs to be hidden if user is not logged in
<div className='layout'>
<Switch>
<Route exact path='/home' component={Home} />
<Route exact path='/login' component={() => <Login setLoggedIn={setLoggedIn} />} />
<SecuredRoute exact path='/about' component={About} />
<Route exact path='/contact' component={Contact} />
<Route exact path='/add' component={AddBlog} />
<Route exact path='/edit/:id' component={UpdateBlog} />
<Route exact path='/blog/:id' component={Blogdetail} />
<Route component={Home} />
</Switch>
</div>
<Footer />
</BrowserRouter>
</>
)
}
export default Layout
I gave a setState to login component. You give a true boolean when the user logs in, loggedIn(true) and the parent state changes.
And in the Navbar component:
return(
loggedIn
?
//The Body of NavBar
:
""
}
)
