React Router v4 nested route to change the entire content - javascript

I have been trying to understand how to apply the concept of nested routes to my scope.
I need these routes:
/projects
Title
List
NavLink to /projects/new
This route will have a list of projects and a button to create a new project.
/projects/new
Form
NavLink to close and go to /projects
When this route is called, will appear a panel above the content, it doesn't change the page projects.
/projects/:projectId/dashboard
Dashboard Title
List of items
When a project is selected, I need to show its dashboard in a whole new page, different than the /projects
My react route config:
<Switch>
<Route exact path='/home' component={Home}/>
<Route path='/home' component={Home}/>
<Route path='/projects' component={Projects} />
<Redirect to="/home" push />
</Switch>
My render inside projects to receive the other route:
<section className='content projects'>
<div>
<h3>List</h3>
<ul>{list}</ul>
</div>
<Route path='/projects/new' render={
() => {
return <div>
<h3>New Project</h3>
<form action="#">
<input type="text" placeholder='Contract name'/>
<input type="text" placeholder='Project name'/>
<button type="submit">Create</button>
</form>
<NavLink to='/projects'>Close</NavLink>
</div>
}
} />
</section>
Now, where should I put this route:
<Route path='/projects/:projectId/dashboard' component={Dashboard} />
I thought if I put inside the switch, would work, but the page gets blank.
Anyone can help me with this? =)
Thanks!
UPDATE 1
I tried to put my dashboard route above /projects with exact.
Now I'm getting a blank content where it should appear the Dashboard component. The route for projects is still working normally.
<Switch>
<Route exact path='/' component={Home}/>
<Route exact path='/projects/:projectId/dashboard' render={ () => {
return <h2>Dashboard</h2>
}} />
<Route path='/projects' component={Projects} />
<Redirect to="/home" push />
</Switch>
UPDATE 2
I have created a separated project and it worked with the answer in this topic. Now I will try to figure out why it didn't work in the project that I'm having blank page.

Try adding the exact prop to the Route and make sure that it appears BEFORE /projects in the Switch:
<Switch>
<Route exact path='/home' component={Home}/>
<Route path='/home' component={Home}/>
<Route exact path='/projects/:projectId/dashboard' component={Dashboard} />
<Route path='/projects' component={Projects} />
<Redirect to="/home" push />
</Switch>
What's happening is your first /projects is matching any route that starts with /projects. Adding the exact prop will make sure that if the route matches /projects/:projectId/dashboard exactly, it will render Dashboard.

How to configure the Routes in Sidebar navigation after Login page in React?

I am designing a users dashboard in React, wherein User logs in and navigate to his dashboard with other links such as Archived, Profile and Settings. My Login and then Navigating to HomePage is working fine.
I have designed the Dashboard, Archived, Profile and Settings Page Links in Sidebar. Now when I am navigating to the Links. It takes me to a new URL path and my Sidebar disappears. I want my sidebar to still appear on all pages as long as I am logged in.
Below is my App.js where I have designed the upper level route:
return (
<div>
<Router history={history}>
<Switch>
<PrivateRoute exact path="/" component={HomePage} />
<Route path="/login" component={LoginPage} />
<Route path="/register" component={RegisterPage} />
<Redirect from="*" to="/" />
</Switch>
</Router>
</div>
);
Once User is on HomePage, I need the dashboard and other links to show. and when User clicks on any Sidebar link, Sidebar should still be there while the other page opens. So I added the inner Routes to the HomePage.jsx like this:
return (
<div>
<Router history={history}>
<Sidebar />
<Switch>
<Route path="/" component={Dashboard} />
<Route path="/archived" component={ArchivedPage} />
<Route path="/profile" component={ProfilePage} />
<Route path="/settings" component={SettingsPage} />
{/* <Redirect from="*" to="/" /> */}
</Switch>
</Router>
</div>
);
But it doesn't work. Can anyone please help me understanding if this is correct. or how can I achieve the required result.
Please let me know if you need any other details.
Thank you.
Issue
The issue is that you are exactly matching "/" to render HomePage, but then as soon as the path is any deeper, like "/archived", it no longer exactly matches and HomePage is unmounted.
You should not render a Router within another Router, you need only one router per app to provide the routing context.
Solution
Remove the inner router (and any other nested routers!!). Remove the exact prop on the "/" path and reorder the routes to specify the more specific paths before less specific paths so the Switch can actually do its job and match and render the appropriate route.
App
Reorder the more specific "/login" and "/register" paths to be matched prior to the less specific "/" path. If you had, for example, a "/login/google" path, this is more specific than "/login" and would be ordered earlier.
return (
<div>
<Router history={history}>
<Switch>
<Route path="/login" component={LoginPage} />
<Route path="/register" component={RegisterPage} />
<PrivateRoute path="/" component={HomePage} />
<Redirect to="/" />
</Switch>
</Router>
</div>
);
HomePage
Move the Dashboard to the last route position so if no other route above it is matched and returned then the dashboard is matched and rendered.
return (
<div>
<Sidebar />
<Switch>
<Route path="/archived" component={ArchivedPage} />
<Route path="/profile" component={ProfilePage} />
<Route path="/settings" component={SettingsPage} />
<Route component={Dashboard} />
</Switch>
</div>
);
in first place your doing something wrong you cant put a Router inside a Router,
you haver a Router in app then inside a component that is inside of app you have another Router thats a problem i dont know if that solves your problem but try it just delete Router in homepage

How do i add an error page to my react router code?

so this is my code
<Router>
<Route path="/" component={Nav}/>
<Route path="/" exact component={Home}/>
<Route path="/updates" exact component={Updates} />
<Route path="/author" exact component={Author} />
<Route path="/" component={Footer}/>
</Router>
It works completely fine i just have a slight problem with it. If i were to go to lets say Author page i can just type /author and it will show not only the author but the navbar and footer because i didn't make them exact on purpose but the problem is if i were to make a random link such as ./ejfjife it will still show the navbar and footer i want to make it so if the user made up a link that doesn't exist it'll redirect them to some kind of 'this page doesn't exist' error
thank you
If you always want your Nav and Footer to be present, they shouldn't even be listed under a Route. They can exist outside your Router. Then your Home component can take a path="/" exact and any other route can take the path="/" Component={Error404}. Like this:
<App>
<Nav />
<Router>
<Route path="/" exact component={Home}/>
<Route path="/updates" exact component={Updates} />
<Route path="/author" exact component={Author} />
<Route path="/" component={Error404}/>
</Router>
<Footer />
</App>

How to load first menu item by default with a different Router Link

I have React Router setup in my Reactjs Project. The header Component has 4 different menu items. After login, I am getting only header component rendered but not first menu item component below it.
I have created a Homepage component which loads Header component and below that I gave Routes for different menu item pages. In the Header component for every Item, I linked it to the corresponding Item Page.
//Home Page Code.
<Router>
<Header />
<Route path='/Jobs' component={Jobs} />
<Route path='/Admin' component={Admin} />
<Route path='/Requests' component={Requests} />
</Router>
To use react router you have to wrap your routes in switch.
Switch will render the first item that matches the current route.
Because you have no switch, the routes are ignored.
To render a default site, change the path of the last route to / and it will match everything.
By setting it as last element, it will always be rendered, if no other route above matches the current route.
<Router>
<Header />
<Switch>
<Route path='/Jobs' component={Jobs} />
<Route path='/Admin' component={Admin} />
<Route path='/' component={Requests} />
</Switch>
</Router>
Hope this helps. Happy coding.
Try putting <Switch></Switch> container around your routes:
//Home Page Code.
<Router>
<Header />
<Switch>
<Route exact path='/' component={Home} />
<Route path='/Jobs' component={Jobs} />
<Route path='/Admin' component={Admin} />
<Route path='/Requests' component={Requests} />
</Switch>
</Router>
Edited: to add path for home (path='/')

React Router: How to render element on all routes, except one?

I have HTML structure like this:
<body>
<nav>
<!--navigation elements -->
</nav>
<div className='main'>
<!--other elements -->
</div>
<div className='container'></div>
</body>
And routing defined like this:
<Router>
<Fragment>
<Navbar />
<Route exact path="/" component={Landing} />
<div className="container">
<Alert />
<Switch>
<Route exact path="/register" component={Register} />
<Route exact path="/login" component={Login} />
<Route exact path="/profiles" component={Profiles} />
</Switch>
</div>
</Fragment>
</Router>
The "container" element is present on all routes however I do not want it to be rendered on the "/" route.
How can I stop <div className="container"> from being rendered on the "/" route? I want it to be rendered on all other routes except of "/".
A solution I found, but don't want to use is to explicitly insert the element with class="container" in each component that is rendered in my <Switch>. Is there a better way?
You should be able to achieve what you require via nested routes and a "no match route".
The idea would be to introduce structure to your routing via nested routes, to restrict rendering of <div className="container"> to non / routes.
To do this, you could extract a component (ie WithContainer) that renders a <Route> for paths; /register, /login and /profiles, inside of the <div className="container">. You would then change your <Switch> to now render two routes for the following route cases;
A <Route/> that renders the Landing component on an exact match of /
A <Route/> that renders your new WithContainer component on no specific route (ie any path that does not exactly match /)
By using the <Switch> in this way, it causes the routing behaviour to render either Landing or WithContainer (but not both) depending on the first matched route. We take advantage of that behaviour to restrict rendering of the WithContainer (and in turn, the <div className="container"> element) for "non /" routes.
In code, this approach could be expressed as:
const WithContainer = () => (
<div className="container">
{ /* Wrap routes in container div */ }
<Route exact path="/register" component={Register} />
<Route exact path="/login" component={Login} />
<Route exact path="/profiles" component={Profiles} />
</div>)
const Main = () => (
<main>
<Switch>
<Route exact path='/' component={Landing}/>
<Route component={ WithContainer } /> {/* No match route */ }
</Switch>
</main>
)
Hope that helps!
With the latest version of React Router, you can provide an array of strings for the path prop so that a specific route renders on multiple matches:
<Route path={['/one', '/two', '/three']} component={SomeComponent} />
Here's a link to the relevant documentation: https://reacttraining.com/react-router/web/api/Route/path-string-string.
If you don't want to create a separate component, you can just do this. You need to keep the inner switch as well, if you want to keep the original functionality.
// parent switch
<Switch>
<Route exact path="/" component={Landing} />
// start route wrap!!!
<Route>
<div className="container">
<Switch>
<Route exact path="/register" component={Register} />
<Route exact path="/login" component={Login} />
<Route exact path="/profiles" component={Profiles} />
</Switch>
</div>
</Route>
// end route wrap!!!
</Switch>
You should think of Routes as of any other UI components. You can nest them arbitrarily.

react router v4 route changed but did not render the correct component

I have 2 level of route, the first layer it look like this
<BrowserRouter>
<div>
<AuthRoute></AuthRoute>
<Switch>
<Route path='/dashboard' component={Dashboard} />
</Switch>
</div>
</BrowserRouter>
where in AuthRoute I have a redirect upon componentDidMount
this.props.history.replace(/dashboard/redirected)
The problem is within the dashboard/index which is my 2nd level of route config
<BrowserRouter>
<Switch>
<Route exact path='/dashboard' component={()=><h1>dashboard index</h1>} />
<Route exact path='/dashboard/somewhere' component={()=><h1>somewhere</h1>} />
<Route exact path='/dashboard/redirected' component={() => <h1>redirected</h1>} />
</Switch>
</BrowserRouter>
The route changed to /dashboard/redirect but the component didn't render the correct one if you refresh on says /dashboard/somewhere or /dashboard/
You can see the problem clearer in the demo I setup https://codesandbox.io/s/v0v4qok38l
You only need one <BrowserRouter> in the application - removing it from dashboard/index.js will fix your issue.
