How to hide nav if user is not logged in react - javascript

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
:
""
}
)

I want to make a function in react js so that when I click on a Link tag, I set the 'to' path to a setState

[[Link]enter image description here(https://i.stack.imgur.com/CopPx.png)
[enter image description here](https://i.stack.imgur.com/VPoTE.png)
I tried to make a function to set product with setState and in the same time to set the route to product.strMeal(name). The problem is that when i click on the Link tag my route does not update.
<div className="category-container">
{
category.map(meal => {
return (
isLoading ? <Loader /> : (
<Link onClick={() => getClickedProductCompleteInfo(meal.strMeal)} to={`/${product.strMeal}`} className="meal-card" key={meal.idMeal}>
<h3>{meal.strMeal}</h3>
<img className='meal-thumbnail' src={meal.strMealThumb} style={{ width: 200, height: 200 }} alt="meal" />
</Link>
)
)
})
}
</div>
const getClickedProductCompleteInfo = async (meal: string) => {
const productCompleteInfo = await getDataFromApi(`https://www.themealdb.com/api/json/v1/1/search.php?s=${meal}`);
setProduct(productCompleteInfo.meals[0]);
}
<Routes>
<Route path="/" >
<Route index element={<Home isLoading={isLoading} categories={categories} setCurrentCategory={setCurrentCategory} />} />
<Route path={`categories/${currentCategory}`} element={<Category product={product} setProduct={setProduct} currentCategory={currentCategory} getDataFromApi={getDataFromApi} />} />
<Route path={`${product.strMeal}`} element={<Product product={product}/>}/>
<Route path='about' element={<About />} />
<Route path='contact' element={<Contact />} />
<Route path='*' element={<Navigate to="/"></Navigate>} />
</Route>

Context Provider is not a Route component error

I'm getting this error when I wrap some of my routes in a Context Provider tag. I basically need to send the logged user context to each of these routes for them to use or modify. The value sent in the provider is this:
const [loggedUser, setLoggedUser] = useState(null)
const value = useMemo(() => {{ loggedUser, setLoggedUser }}, [loggedUser, setLoggedUser])
And here is the code:
return (
<>
<Routes>
<Route path="/" element={ <MainPage /> } />
<UserContext.Provider value={value}>
<Route path="/login" element={<LoginMenu/>} />
<Route path="/register" element={<RegisterMenu/>} />
<Route path="/dashboard" element={<Dashboard tasks={tasks} />} />
</UserContext.Provider>
</Routes>
</>
)
Only Route component can be a child of a Route component. Abstract the UserContext.Provider component into a layout route.
Example:
import { Routes, Route, Outlet } from 'react-router-dom';
const UserContextProvider = () => (
<UserContext.Provider value={value}>
<Outlet />
</UserContext.Provider>
);
...
<Routes>
<Route path="/" element={<MainPage />} />
<Route element={<UserContextProvider />}>
<Route path="/login" element={<LoginMenu />} />
<Route path="/register" element={<RegisterMenu />} />
<Route path="/dashboard" element={<Dashboard tasks={tasks} />} />
</Route>
</Routes>
Or wrap the entire Routes in the UserContext.Provider component.
Example:
return (
<UserContext.Provider value={value}>
<Routes>
<Route path="/" element={ <MainPage /> } />
<Route path="/login" element={<LoginMenu />} />
<Route path="/register" element={<RegisterMenu />} />
<Route path="/dashboard" element={<Dashboard tasks={tasks} />} />
</Routes>
</UserContext.Provider>
);

Render error render in error content area

const Pages = () => {
return (
<>
<Box display="flex">
{window.location.pathname === "/profile" ? undefined : <Sidebar />}
<Box flex={3}>
<Navbar />
<Routes>
{/* Content Area */}
<Route exact path="/" element={<Dashboard />} />
<Route exact path="/calendar" element={<Calendar />} />
<Route exact path="/task" element={<div>Task</div>} />
<Route exact path="/projects" element={<div>Projects</div>} />
<Route exact path="/teamMember" element={<div>Team Member</div>} />
<Route exact path="/profile" element={<Profile />} />
{/* Error Path */}
<Route path="*" element={<div>404</div>} />
</Routes>
</Box>
</Box>
</>
);
};enter code here
Hello, where do I put my error path because when it renders, it renders on my content area?
It is because you continually render a layout(Box, Sidebar, Navbar). There are a few options in order to achieve your request you have to either:
create a Layout component that will render Box, Sidebar, and Navbar inside and use that Layout inside your pages, for example:
const Dashboard = () => {
// ...
return (
<Layout>
Dashboard content
</Layout>
)
}
or use the benefit of the new latest react-router package:
import { Outlet } from 'react-router-dom'
const Layout = () => {
return (
<Box display="flex">
{window.location.pathname === "/profile" ? undefined : <Sidebar />}
<Box flex={3}>
<Navbar />
<Outlet /> {/* Roughly speaking this is `children`. Refer to the documentation */}
</Box>
)
}
<Routes>
<Route element={<Layout />} path="/">
<Route index element={<Dashboard />} />
<Route path="/calendar" element={<Calendar />} />
<Route path="/task" element={<div>Task</div>} />
<Route path="/projects" element={<div>Projects</div>} />
<Route path="/teamMember" element={<div>Team Member</div>} />
<Route path="/profile" element={<Profile />} />
</Route>
<Route path="*" element={<div>404</div>} />
</Routes>

No routes matching location "/dash/1"

I have the following problem. my route is not registered and i dont know why.
Links
dashboard.jsx
this code generates all the links.
<div className="flex w-3/4 m-auto flex-col mt-10 xl:w-1/2">
{questions.map(({ id, question }) => {
return (
<Link to={`/dash/${id}`}>
<QuestionHeader question={question} />
</Link>
);
})}
</div>
/dash/1,/dash/2,.... are generated by the map function above.
i have two files that represent the routes.
NavRoutes
const NavRoutes = () => {
return (
<Routes>
<Route path="/:id" element={<Question />} />
<Route path="" element={<Dashboard />} />
</Routes>
);
};
export default NavRoutes;
here is the Main component
const Main = () => {
return (
<div>
<NavBar />
<NavRoutes />
<Footer />
</div>
);
};
export default Main;
and the main routes for authentication and accessing the main page
const App = () => {
let { user } = useAuthContext();
return (
<div className="w-full bg-slate-700 block fixed h-full">
<Header />
<Router>
<Routes>
<Route
path="/dash"
element={!user ? <Navigate to="/auth" /> : <Main />}
>
</Route>
<Route path="" element={<Login />} />
</Routes>
</Router>
</div>
);
};
when i try to access /dash/1, i get the following error
router.ts:11 No routes matched location "/dash/1"
Did you try the following in your NavRoutes (prepending '/dash' to '/:id'):
<Route path="/dash/:id" element={<Question />} />
i solved this by doing the following
const App = () => {
let { user } = useAuthContext();
return (
<div className="w-full bg-slate-700 block fixed h-full">
<Header />
<Router>
<Routes>
<Route
path="/dash/*"
element={!user ? <Navigate to="/auth" /> : <Main />}
>
</Route>
<Route path="/auth" element={<Login />} />
</Routes>
</Router>
</div>
);
};
you need to include a * when nesting deeper

how to render same component in every route

import ...
const App = () => {
const [showModal, setShowModal] = useState(false);
const toggleModalShow = () => {
setShowModal(!showModal);
};
return (
<div className="app">
<Router>
<ScrollToTop>
<Routes>
<Route
exact
path="/"
element={
<>
<Header
toggleModalShow={toggleModalShow}
showModal={showModal}
/>
<main className="main">
<Home />
</main>
</>
}
/>
<Route
path="/games/:game"
element={
<>
<Header
toggleModalShow={toggleModalShow}
showModal={showModal}
/>
<GameLobby />
</>
}
/>
<Route
path="/games"
element={<PrivateRoute isLoggedIn={isLoggedIn} />}
>
<Route
path="/games"
element={
<>
<Header
toggleModalShow={toggleModalShow}
showModal={showModal}
/>
<Games />
</>
}
/>
</Route>
</Routes>
</ScrollToTop>
</Router>
</div>
);
};
export default App;
Hi all.i want to show <Header /> component in every route but to this i have to use <Header /> component in every <Route />. Is there any way to do that without ? Finally i would be appreciate if you give me feedback about project.
repo : https://github.com/UmutPalabiyik/mook
deploy: https://mook-f2b4e.web.app
for testing:
username: test
pass: 123
Just move the Header above Routes:
return (
<div className="app">
<Router>
<Header
toggleModalShow={toggleModalShow}
showModal={showModal}
/>
<ScrollToTop>
<Routes>
<Route
exact
path="/"
element={
<>
<main className="main">
<Home />
</main>
</>
}
/>
...
</Routes>
</ScrollToTop>
</Router>
</div>
);
};
