Being a beginner in reactJS, I want to know how to hide parent component when i route to child component URL
Assume a scenario:
User is at "/house" as this:
<Route path="/house" component={House} />
when user clicks a house grid he navigates to "/house/flat/:flatID". Inside House component
<Route
path={`${this.props.match.url}/flat/:flatId`}
render={() => <div>Each Flat details</div>}
/>
then both child and parent components are visible like this:
So what i want is to show only flat component when user navigates to "/house/flat:FlatId". Please suggest me anything that helps ! Any links to article so that i can learn and achieve such functionality.
Code:
App.js
<Switch>
<Route exact path="/" component={Home} />
<Route exact path="/account" component={Account} />
<Route path="/gharjagga" component={GharJagga} />
</Switch>
House.js
onGharGridClick= id => {
<Redirect to={`${this.props.match.url}/flat/${id}`} />;
};
return (
<Route
path={`${this.props.match.url}/flat/:fkatId`}
render={() => <div>Ghar Each</div>}
/>
);
You can achieve it different ways
define routes in the parent component, I think this is the best option.
<Switch>
<Route path="/account" component={Account} />
<Route path="/house/flat/:flatId" component={FlatComponent}/>
<Route path="/house" component={House} />
<Route path="/" component={Home} />
</Switch>
Note: instead of using exact, order your routes based on priority, that will make the route to redirect to next matching route if any typo in the route entered
You can make House as separate route component, and nest the routes inside that component
// Routes
<Switch>
<Route path="/account" component={Account} />
<Route path="/house" component={House} />
<Route path="/" component={Home} />
</Switch>
// House component
class House extends React. Components {
render() {
return (
<Switch>
<Route path="/house/flat/:flatId" render={() => <div>Each Flat details</div>} />}/>
<Route path="/house" component={HouseGridComponent} />
</Switch>
)
}
}
you can check whether the route has flatId and hide the elements, in your House component you can check this.props.match.params.flatId, if the flatId is set you can hide that House Component.
// House Component
class House extends React. Components {
render() {
return (
<div>
{
!this.props.match.params.flatId?
<h1>House Component</h1>:
null
}
<Route path={`${this.props.match.url}/flat/:flatId`} render={() => <div>Each Flat details</div>} />
</div>
)
}
}
The solution is to raise "/house/flat/:flatId" to the same level as "/house".
<Switch>
<Route exact path="/" component={Home} />
<Route path="/account" component={Account} />
<Route path="/house/flat/:flatId" render={() => <div>Each Flat details</div>}/>
<Route path="/house" component={House} />
</Switch>

My application has scenarios where we need several routes to "pass" through a component to only then render the specifics, not only that but also situations where something is shown for the "parent" route and then split for the children...
It is imperative to note that we don't have a single "route config" file, and instead our routes are where we need them.
This was possible with v5, but I am very confused about how to get this accomplished with the new version.
So, currently we have stuff such as:
App.js
function App = () => {
return (
<Switch>
<Route exact path={['/', '/2', '/more-info']} component={Login} />
<Route path="/(main|settings|notifications)" component={AuthenticatedUser} />
<Redirect from="*" to="/404" />
</Switch>
);
}
AuthenticatedUser.js
function AuthenticatedUser= () => {
{... lots of common code}
return (
<div>
{...common html}
<Switch>
<Route exact path="/main" component={Main} />
<Route path="/settings" component={Settings} />
<Route path="/notifications" component={Notifications} />
</Switch>
</div>
);
}
Settings.js
function Settings= () => {
{... lots of common code}
return (
<div>
{...common html}
<Switch>
<Route exact path="/settings/basic" component={Basic} />
<Route exact path="/settings/notifications" component={Notifications} />
</Switch>
</div>
);
}
Now, with the relative from the parent, I am not able to get the same structure, I am also confused about how to get the routes split into separate files not even talking about the regex situation that I am guessing the solution is to duplicate the lines as many times as I have items in that regex...
You have basically 2 options when it comes to declaring the routes and sharing common UI:
Use layout routes and nested Route components.
Render routed components that render descendent routes in another Routes component wrapping descendent Route components.
Using layout and nested routes
Convert AuthenticatedUser into a layout route. Layout routes render an Outlet for nested routes to render their matched element into.
import { Outlet } from 'react-router-dom';
function AuthenticatedUser = () => {
{... lots of common code}
return (
<div>
{...common html}
<Outlet />
</div>
);
};
Convert Settings also into a layout route component.
import { Outlet } from 'react-router-dom';
function Settings = () => {
{... lots of common code}
return (
<div>
{...common html}
<Outlet />
</div>
);
};
App
import { Routes, Route, Navigate } from 'react-router-dom';
function App = () => {
return (
<Routes>
<Route path="/" element={<Login />} />
<Route path="/2" element={<Login />} />
<Route path="/more-info" element={<Login />} />
<Route element={<AuthenticatedUser />}>
<Route path="/main" element={<Main />} />
<Route path="/settings" element={<Settings />}>
<Route
path="basic" // "/settings/basic"
element={<Basic />}
/>
<Route
path="notifications" // "/settings/notifications"
element={<Notifications />}
/>
</Route>
<Route path="/notifications" element={<Notifications />} />
</Route>
<Route path="*" element={<Navigate to="/404" replace />} />
</Routes>
);
};
Using descendent routes
Here the parent routes need to render their route path with a trailing "*" wildcard matcher so descendent routes can also be matched. Descendent Routes components build their route paths relative to their parent Route path. I'd still suggest using AuthenticatedUser as a layout route for ease, otherwise you'll have a lot of code duplication since you'd need to wrap each route individually.
App
import { Routes, Route, Navigate } from 'react-router-dom';
function App = () => {
return (
<Routes>
<Route path="/" element={<Login />} />
<Route path="/2" element={<Login />} />
<Route path="/more-info" element={<Login />} />
<Route element={<AuthenticatedUser />}>
<Route path="/main" element={<Main />} />
<Route path="/settings/*" element={<Settings />} />
<Route path="/notifications" element={<Notifications />} />
</Route>
<Route path="*" element={<Navigate to="/404" replace />} />
</Routes>
);
};
Settings
import { Routes } from 'react-router-dom';
function Settings = () => {
{... lots of common code}
return (
<div>
{...common html}
<Routes>
<Route
path="/basic" // "/settings/basic"
element={<Basic />}
/>
<Route
path="/notifications" // "/settings/notifications"
element={<Notifications />}
/>
</Routes>
</div>
);
};
How do i hide certain components on certain pages in my app?
Specifically I need to hide Navbar and Header from the Settings page.
in App.js i set up a router:
<div>
<Router>
<Switch>
<Header/> <- header and navbar are here
<Navbar/>
<Route exact path = "/" component= { Data } />
<Route path = "/available-data" component= { Data } />
<Route path = "/devices" component= { Devices } />
<Route path = "/contacts" />
<Route path = "/chat" />
<Route path = "/settings" component = { Settings } /> <- i need to remove them from here
</Switch>
</Router>
</div>
Header and Navbar are used in every component except in Settings. How do i go about removing/hiding them?
All three of the files are function components with useState hooks(if they even have state) if it matters :)
You can render a second switcher component to only route to pages with the header and navbar UI.
// in App.js
<div>
<Router>
<Switch>
<Route exact path="/settings" component={Settings} />
<Route path='/' ><UiRouter /></Route>
</Switch>
</Router>
</div>
// in UiRouter.js
export default function UiRouter() {
return (
<>
<Header />
<Navbar />
<Switch>
<Route exact path="/" component={Data} />
<Route path="/available-data" component={Data} />
<Route path="/devices" component={Devices} />
<Route path="/contacts" component={Contacts}/>
<Route path="/chat" component={Chat}/>
</Switch>
</>
);
}
Also, as Ajith mentioned, you should not have the components that you want to render for each route (Header and Navbar) inside the Switch component.
To hide the navbar on the home component I am doing the following
const NavbarComponent = (props) => {
console.log(props);
if (props.match.path === '/') {
return null;
} else
return (
it works fine, I need to have access to the router so I can send people to locations dependant on the props object , is there a better way to do it such that I have all router logic in the same place?
this is the current state of my router
return (
<div>
<Router>
<Route component={Navbar} />
<Switch>
<Route exact path="/" component={Home} />
<Route exact path="/api/:city/electronics" component={Electronics} />
<Route exact path="/api/:city/labour" component={Labour} />
<Route exact path="/api/posts/item/:id" component={ItemDetails} />
<Route exact path="/create/:city/:category" component={CreatePost} />
</Switch>
</Router>
</div>
);
thanks for your time.
I'm not sure I understand why your NavBar component is in it's own Route. Any components contained within the Router have access to the entire Router api, including Link - they do not need to be a Route to do so.
I would suggest wrapping all the Routes that include the NavBar with that component. The Routes will then be displayed as children of the Navbar component.
Here is a simplified example:
// App.js
return (
<div>
<Router>
<Switch>
<Route exact path="/" component={Home} />
<NavBar>
<Route exact path="/electronics" component={Electronics} />
<Route exact path="/labour" component={Labour} />
</NavBar>
</Switch>
</Router>
</div>
);
//NavBar.js
return (
<>
<div>
<Link to="/electronics">Electronics</Link>
<Link to="/labour">Labour</Link>
</div>
<div>{props.children}</div>
</>
);

I am trying to group some of my routes together with React Router v4 to clean up some of my components. For now I just want to have my non logged in routes group together and my admin routes grouped together but the following doens't work.
main.js
const Main = () => {
return (
<main>
<Switch>
<Route exact path='/' component={Public} />
<Route path='/admin' component={Admin} />
</Switch>
</main>
);
};
export default Main;
public.js
const Public = () => {
return (
<Switch>
<Route exact path='/' component={Greeting} />
<Route path='/signup' component={SignupPage} />
<Route path='/login' component={LoginPage} />
</Switch>
);
};
export default Public;
The Greeting component shows at "localhost:3000/", but the SignupPage component does not show at "localhost:3000/signup" and the Login component doesn't show at "localhost:3000/signup". Looking at the React Dev Tools these two routes return Null.
The reason is very obvious. for your route in main.js, you have specified the Route path of Public component with exact exact path='/' and then in the Public component you are matching for the other Routes. So if the route path is /signup, at first the path is not exact so Public component is not rendered and hence no subRoutes will.
Change your route configuration to the following
main.js
const Main = () => {
return (
<main>
<Switch>
<Route path='/' component={Public} />
<Route path='/admin' component={Admin} />
</Switch>
</main>
);
};
export default Main
public.js
const Public = () => {
return (
<Switch>
<Route exact path='/' component={Greeting} />
<Route path='/signup' component={SignupPage} />
<Route path='/login' component={LoginPage} />
</Switch>
);
};
Also when you are specifying the nested routes these should be relative to the parent Route, for instance if the parent route is /home and then in the child Route you wish to write /dashboard . It should be written like
<Route path="/home/dashboard" component={Dashboard}
or even better
<Route path={`${this.props.match.path}/dashboard`} component={Dashboard}
Did anyone know how to create for any path that ends with '/popup-image-:id' ? i have website where each image could be opened in popup on any page. So, if i couldn't implement '/popup-image-:id' i have to double each route in my website to place inside. I would like avoid redundance and fragility.
my current routing:
<Router history={browserHistory}>
<Route path="/" component={Base}>
<Route path="profile" component={Profile}>
<Route path="popup-image-:id" component={Full_Piture} />
</Route>
<Route path="feed" component={Feed_List}>
<Route path="popup-image-:id" component={Full_Piture} />
</Route>
<Route path="user-:id" component={User_Page}>
<Route path="popup-image-:id" component={Full_Piture} />
</Route>
</Route>
</Router>
As u can see i had to produce a lot of duplicated code. If i could write something like <Route path="*/popup-image-:id" component={Full_Piture} /> it will be much cleaner and solid code
Is the parent <Route> also supposed to match? If it isn't, you should be able to use the ** syntax.
<Route path="/**/popup-image-:id" component={Full_Picture} />
If the parent <Route> should also match, you could create a <RouteWithPopup> component that returns a <Route> which has the <Route path='popup-image-:id'> as its child.
const RouteWithPopup = (props) => {
return (
<Route {...props}>
<Route path="popup-image-:id" component={Full_Picture} />
</Route>
)
}
Then you could turn your route config into:
<Router history={browserHistory}>
<Route path="/" component={Base}>
<RouteWithPopup path="profile" component={Profile} />
<RouteWithPopup path="feed" component={Feed_List} />
<RouteWithPopup path="user-:id" component={User_Page} />
</Route>
</Router>
