react-router-dom switch not rendering components after dynamic path - html

I`ve been following an e-commerce tutorial and building on top of it. Im new to React and React Router Dom.
I've set a dynamic path for individual product pages, and now i' trying to add some new paths i.e. contact, about, etc.. If I add the new paths above the dynamic path they are rendered properly, but if I place the routes under the one with the dynamic path, for example the /hello, they won't render. Is this normal behaviour??
<Router>
<div>
<Navbar totalItems={cart.total_items} />
<Switch>
<Route exact path="/">
<Home products={products} handleAddToCart={handleAddToCart} fetchProduct={fetchProduct} />
</Route>
<Route exact path="/checkout">
<Checkout cart={cart} order={order} handleCaptureCheckout={handleCaptureCheckout} error={errorMessage} refreshCart={refreshCart} />
</Route>
<Route exact path="/cart">
<Cart
cart={cart}
handleUpdateCartQuantity={handleUpdateCartQuantity}
handleRemoveFromCart={handleRemoveFromCart}
handleEmptyCart={handleEmptyCart}
/>
</Route>
<Route exact path="/contact">
<Contact />
</Route>
<Route exact path="/:id">
<Details product={product} handleAddToCart={handleAddToCart} />
</Route>
<Route exact path="/hello">
<h1>Hello World</h1>
</Route>
</Switch>
</div>
<Router>

Yes, this behavior is completely normal, and expected. Recall that the Switch component "Renders the first child <Route> or <Redirect> that matches the location." This means that in the Switch component path order and specificity matter!
A path "/hello" is more specific than "/:id", so depending on route order may or may not be matched first. Or in other words, "/hello" can always be matched to "/:id", but not always the other way around.
You should always order the routes from more specific paths to less specific paths, and if done correctly there should be a near zero need for the exact prop.
"/hello" is more specific than "/:id" which is more specific than "/".
<Switch>
<Route path="/checkout">
<Checkout ... />
</Route>
<Route path="/cart">
<Cart ... />
</Route>
<Route path="/contact">
<Contact />
</Route>
<Route path="/hello">
<h1>Hello World</h1>
</Route>
<Route path="/:id">
<Details ... />
</Route>
<Route path="/">
<Home ... />
</Route>
</Switch>
If you had a nested "/contact/add" route for example, this is more specific than "/contact" and should be listed higher/before in the Switch.

Try removing the exact from the Route.
<Route exact path="/:id">
to:
<Route path="/:id">

Conditional rendering with React Router

I'd like to render some routes with a nav at the top, while rendering other routes (like a sign-up / sign-in page) without any nav.
For the setup with the nav, I have:
const App = () => (
<Router>
<div>
<Nav />
<div>
<Route exact path="/" component={Home} />
<Route path="/account" component={Account} />
<Route path="/news" component={News} />
</div>
<Footer />
</div>
</Router>
);
I'm trying to find the best way of handling this with React Router (seems like it would have to handled with some type of conditional maybe? - "if my current route matches any one of these routes, then render like so else render this.").
Thanks!
You have at least two possibilities:
Use Route "path" property to test the route and render the component. Path property accepts path.to.regexp expressions.
Wrap your component with withRouter method and inside Nav test if the route matches and render null otherwise.
First answer:
const App = () => (
<Router>
<div>
<Route path="/(?!signin|signup)" component={Nav}/>
<div>
<Route exact path="/" component={Home} />
<Route path="/account" component={Account} />
<Route path="/news" component={News} />
</div>
<Footer />
</div>
</Router>
);
Second answer:
import { withRouter } from 'react-router'
const NavWithRouter = withRouter(Nav);
const App = () => (
<Router>
<div>
<NavWithRouter/>
<div>
<Route exact path="/" component={Home} />
<Route path="/account" component={Account} />
<Route path="/news" component={News} />
</div>
<Footer />
</div>
</Router>
);
<Route
path={`foo/(A|B|C)`}
component={() => (<Baz {...props}/>)}
/>
Where A,B,C are the different routes like foo/A.
I usually use two different Layout pages. And within the Layout pages, have a router for the content.
My code will look like this:
<Router>
<Route path="/login" component={AuthLayout} />
<Route path="/logout" component={AuthLayout} />
<Route path="/some/path" component={Layout} />
</Router>
Within each Layout, there will be the usual header / footer / navbars and then another set of routes.
<div className="auth-layout">
<header className="auth-layout__header"></header>
<main className="auth-layout__content">
<Switch>
<Route path="/login" component={Login} />
<Route path="/logout" component={Logout} />
</Switch>
</main>
</div>
In this way, I have a direct mapping from requirements to code. In my code, there are much more differences between the two layouts.
Just use a prop for this & inside the children your are able to conditional render the nav.
<Route exact path="/" render={() => <Home hasNav={false} />}

Nested Routes in React Router v4

I'm trying to set up some nested routes to add a common layout. Check the code out:
<Router>
<Route component={Layout}>
<div>
<Route path='/abc' component={ABC} />
<Route path='/xyz' component={XYZ} />
</div>
</Route>
</Router>
While this works perfectly fine, I still get the warning:
Warning: You should not use <Route component> and <Route children> in the same
route; will be ignored
CESCO's answer renders first the component AppShell then one of the components inside Switch. But these components are NOT going to render inside AppShell, they will NOT be children of AppShell.
In v4 to wrap components you don't put anymore your Routes inside another Route, you put your Routes directly inside a component.
I.E : for the wrapper instead of <Route component={Layout}> you directly use <Layout>.
Full code :
<Router>
<Layout>
<Route path='/abc' component={ABC} />
<Route path='/xyz' component={XYZ} />
</Layout>
</Router>
The change is probably explained by the idea to make React Router v4 to be pure
React so you only use React elements like with any other React element.
EDIT : I removed the Switch component as it's not useful here. See when it's useful here.
You need to use the switch component to nesting to work nice. Also, see this question
// main app
<div>
// not setting a path prop, makes this always render
<Route component={AppShell}/>
<Switch>
<Route exact path="/" component={Login}/>
<Route path="/dashboard" component={AsyncDashboard(userAgent)}/>
<Route component={NoMatch}/>
</Switch>
</div>
And version-4 components do not take children, instead, you should use the render prop.
<Router>
<Route render={(props)=>{
return <div>Whatever</div>}>
</Route>
</Router>
Try:
<Router>
<Layout>
<Route path='/abc' component={ABC} />
<Route path='/xyz' component={XYZ} />
</Layout>
</Router>
If you do not want Layout to run at loaded. Use this method:
<div className="container">
<Route path="/main" component={ChatList}/>
<Switch>
<Route exact path="/" component={Start} />
<Route path="/main/single" component={SingleChat} />
<Route path="/main/group" component={GroupChat} />
<Route path="/login" component={Login} />
</Switch>
</div>
Whenever history changes, componentWillReceiveProps in the ChatList will run.
You can also try this :
<Route exact path="/Home"
render={props=>(
<div>
<Layout/>
<Archive/>
</div>
)}
/>

Adding deep Links using react-router

Using the below Route configuration -
<Router history={hashHistory}>
<Route name="Home" path="/" component={BaseLayout}>
<Route name="Gateways" path="/gateways" component={DashboardLayout}>
<Route name="Login" path="/login" component={Login}/>
<Route name=":id" path="/gateways/:id">
<IndexRoute name="Dashboard" component={ViewGateWay}/>
<Route name="Access Points" path="/accesspoints" component={AccessPoints}>
<Route name=":id" path="/:id" component={ViewAccessPoint}/>
</Route>
<Route name="Devices" path="/devices" component={Devices}>
<Route name=":id" path="/:id" component={ViewDevice}/>
</Route>
</Route>
<IndexRoute component={Gateways} />
</Route>
<IndexRedirect to="Login" />
</Route>
</Router>
Using name in the Route for breadcrumbs. Have a side menu which have links to /gateways/:id, /gateways/:id/devices, /gateways/:id/accesspoints, further the last two have links to individual devices and access points using Link as /gateways/:id/devices/:id and /gateways/:id/accesspoints/:id. When I am giving the link in the side menu as
<Link to="/gateways/${this.props.params.id}/accesspoints">Access Points</Link>
OR
<Link to="/accesspoints">Access Points</Link>
I am not getting the correct page. Same goes with the devices link. I am trying to achieve the below API's along with breadcrumb.
home/gateways/GW_ID1/dashboard
home/gateways/GW_ID1/accesspoints
home/gateways/GW_ID1/accesspoints/GW_AP1
home/gateways/GW_ID1/devices
home/gateways/GW_ID1/devices/GW_DV1
What is the correct way to Link ? Not using any handler.
After a bit of brainstorming, came up with a solution what I wanted to achieve
<Route name=":gid" path="/gateways/:gid">
<Route name="Dashboard" path="/gateways/:gid/dashboard" component={ViewGateWay}/>
<Route name="Access Points" path="/gateways/:gid/accesspoints" component={AccessPoints}>
<Route name=":apid" path="/gateways/:gid/accesspoints/:apid" component={ViewAccessPoint}/>
</Route>
<Route name="Devices" path="/gateways/:gid/devices" component={Devices}>
<Route name=":did" path="/gateways/:gid/devices/:did" component={ViewDevice}/>
</Route>
</Route>

Multilanguage support in react router

I'm building multilingual site where the language preference is part of the URL, e.g.
http://example.com/<somepage> (Russian, default)
http://example.com/en/<somepage> (English)
http://example.com/jp/<somepage> (Japanese)
http://example.com/../ (etc)
Everything is ok, when I use prefix for all languages:
<Route path="/:lang">
<Route path="somepage" component={Somepage}/>
</Route>
But for default language, I don't need to include language in url, as shown in example.
In fluxible router it can be solved by using regexp in path:
path: '/:lang([a-z]{2})?/<somepage>'
But it doesn't work in react router, because path must be a string, not a regexp.
Any ideas how to handle this use case?
Have you tried duplicating your routes? Seems to work for me thus far.
var innerRoutes = (
<Route>
<Route path="somepage" component={Somepage}/>
<Route path="otherpage" component={Otherpage}/>
</Route>
);
var routes = (
<Route path="/" component={App}>
{innerRoutes}
<Route path=":lang">
{innerRoutes}
</Route>
</Route>
);
your routes would need to look like:
<Router history={createBrowserHistory()}>
<Route component={App}>
<IndexRoute component={Home} />
<Route path=':lang/'>
<Route path='about' component={About} />
</Route>
<Redirect from='*' to='ru/about' />
</Route>
</Router>
The trailing slash in the :lang/ indicates that it will only be matched if the URL contains something after it (e.g. /de/about) otherwise there is a Redirect with a greedy matching which will always redirect to the page you specify in the to parameter. You can read more about Route Matching in the docs.
If you are using react-router v4 and react-intl you can use react-i18n-routing library

React Router v. 1.0.0-rc3 Parameter in Path Matching Fixed Path Too

I'm using react-router v. 1.0.0-rc3 and I have a route configuration as follows:
<Route path="/" component={App}>
<IndexRoute component={Home} />
<Route path="track/:id" component={Track} />
<Route path="track/new/" component={NewTrack} />
</Route>
When I navigate to track/new/, it is matching the track/:id path and the component Track gets used. This didn't happen before. Do I need to change my paths or is there any way to keep this path format?
just swap them around:
<Route path="/" component={App}>
<IndexRoute component={Home} />
<Route path="track/new" component={NewTrack} />
<Route path="track/:id" component={Track} />
</Route>
