Route

<Route> renders a route configuration object to be used by the <Routes> component.
tsx
<Route path="/students" component={Students} />
tsx
<Route path="/students" component={Students} />


Usage

The <Route> component allows the manual registration of routes when added as children to the <Routes> component. It is a re-export from @solidjs/router. If only using file system routing you probably will not need any of the information on this page. But it can serve as a reference to how this works under the hood.

root.tsx
tsx
import { Routes, Route } from "solid-start";
 
import Home from "./pages/Home";
import Users from "./pages/Users";
 
export default function RootLayout() {
return (
<>
<h1>My Site with Lots of Pages</h1>
<Routes>
<Route path="/" component={Home} />
<Route path="/users" component={Users} />
<Route path="/about" element={<div>This site was made with Solid</div>} />
</Routes>
</>
);
}
root.tsx
tsx
import { Routes, Route } from "solid-start";
 
import Home from "./pages/Home";
import Users from "./pages/Users";
 
export default function RootLayout() {
return (
<>
<h1>My Site with Lots of Pages</h1>
<Routes>
<Route path="/" component={Home} />
<Route path="/users" component={Users} />
<Route path="/about" element={<div>This site was made with Solid</div>} />
</Routes>
</>
);
}

Reference

<Route>

Render <Route> components as children of the <Routes> component to define your own routes, even alongside the file system routes. They are merged together by the <Routes> component.

Props

Prop Type Description
path string The path segment for this portion of the route.
component function A component definition to be instantiated on route match. Only one of `element` or `component` should be present.
element unknown The element defines an expression that is run when the route is matched. Generally this is an instantiated component. Only one of `element` or `component` should be present.
data function Method for registering data loading functions that run in parallel on route match.

Dynamic Routes

If you don't know the path ahead of time, you might want to treat part of the path as a flexible parameter that is passed on to the component.

root.tsx
tsx
import { lazy } from "solid-js";
import { Routes, Route } from "solid-start"
 
const Users = lazy(() => import("./pages/Users"));
const User = lazy(() => import("./pages/User"));
const Home = lazy(() => import("./pages/Home"));
 
export default function RootLayout() {
return <>
<h1>My Site with Lots of Pages</h1>
<Routes>
<Route path="/users" component={Users} />
<Route path="/users/:id" component={User} />
<Route path="/" component={Home} />
<Route path="/about" element={<div>This site was made with Solid</div>} />
</Routes>
</>
}
root.tsx
tsx
import { lazy } from "solid-js";
import { Routes, Route } from "solid-start"
 
const Users = lazy(() => import("./pages/Users"));
const User = lazy(() => import("./pages/User"));
const Home = lazy(() => import("./pages/Home"));
 
export default function RootLayout() {
return <>
<h1>My Site with Lots of Pages</h1>
<Routes>
<Route path="/users" component={Users} />
<Route path="/users/:id" component={User} />
<Route path="/" component={Home} />
<Route path="/about" element={<div>This site was made with Solid</div>} />
</Routes>
</>
}

The colon indicates that id can be any string, and as long as the URL fits that pattern, the User component will show.

You can then access that id from within a route component with useParams:

jsx
import { A, useParams } from "solid-start";
import { createResource } from "solid-js";
 
export default function User () {
const params = useParams();
const [userData] = createResource(() => params.id, fetchUser);
return <A href={userData.twitter}>{userData.name}</A>
}
jsx
import { A, useParams } from "solid-start";
import { createResource } from "solid-js";
 
export default function User () {
const params = useParams();
const [userData] = createResource(() => params.id, fetchUser);
return <A href={userData.twitter}>{userData.name}</A>
}

Optional Parameters

Parameters can be specified as optional by adding a question mark to the end of the parameter name:

jsx
// Matches stories and stories/123 but not stories/123/comments
<Route path='/stories/:id?' element={<Stories/>} />
jsx
// Matches stories and stories/123 but not stories/123/comments
<Route path='/stories/:id?' element={<Stories/>} />

Wildcard Routes

:param lets you match an arbitrary name at that point in the path. You can use * to match any end of the path:

jsx
// Matches any path that begins with foo, including foo/, foo/a/, foo/a/b/c
<Route path='foo/*' component={Foo}/>
jsx
// Matches any path that begins with foo, including foo/, foo/a/, foo/a/b/c
<Route path='foo/*' component={Foo}/>

If you want to expose the wild part of the path to the component as a parameter, you can name it:

jsx
<Route path='foo/*any' element={<div>{useParams().any}</div>}/>
jsx
<Route path='foo/*any' element={<div>{useParams().any}</div>}/>

Note that the wildcard token must be the last part of the path; foo/*any/bar won't create any routes.

Multiple Paths

Routes also support defining multiple paths using an array. This allows a route to remain mounted and not rerender when switching between two or more locations that it matches:

jsx
// Navigating from login to register does not cause the Login component to re-render
<Route path={["login", "register"]} component={Login}/>
jsx
// Navigating from login to register does not cause the Login component to re-render
<Route path={["login", "register"]} component={Login}/>

Route Data Functions

In the above example, the User component is lazy-loaded and then the data is fetched. With route data functions, we can instead start fetching the data parallel to loading the route, so we can use the data as soon as possible.

To do this, create a function that fetches and returns the data using createResource. Then pass that function to the data prop of the Route component.

root.tsx
tsx
// Route Data function
function studentData({ params, location, navigate, data }: RouteDataArgs) {
const [student] = createResource(() => params.id, fetchStudent);
return student;
}
 
// Pass it in the route definition
<Route
path="/students/:id"
component={StudentProfile}
data={studentData}
/>;
root.tsx
tsx
// Route Data function
function studentData({ params, location, navigate, data }: RouteDataArgs) {
const [student] = createResource(() => params.id, fetchStudent);
return student;
}
 
// Pass it in the route definition
<Route
path="/students/:id"
component={StudentProfile}
data={studentData}
/>;

When the route is loaded, the data function is called, and the result can be accessed by calling useRouteData() in the route component.

pages/students/[id].tsx
tsx
import { useRouteData } from 'solid-start';
 
export default function StudentProfile() {
const student = useRouteData<typeof studentData>();
return <h1>{student()?.name}</h1>;
}
pages/students/[id].tsx
tsx
import { useRouteData } from 'solid-start';
 
export default function StudentProfile() {
const student = useRouteData<typeof studentData>();
return <h1>{student()?.name}</h1>;
}

Nested Routes

The following two route definitions have the same result:

jsx
<Route path="/users/:id" component={User} />
jsx
<Route path="/users/:id" component={User} />
jsx
<Route path="/users">
<Route path="/:id" component={User} />
</Route>
jsx
<Route path="/users">
<Route path="/:id" component={User} />
</Route>

/users/:id renders the <User/> component, and /users/ is an empty route. Only leaf Route nodes (innermost Route components) are given a route.

If you want to make the parent its own route, you have to specify it separately. So, if you want to render a page with <Users> for /users and <User> for /users/:id, you need to specify both as leaf routes:

jsx
// This is not a leaf route, its actually a parent layout route
<Route path="/users" component={Users}>
<Route path="/:id" component={User} />
</Route>
jsx
// This is not a leaf route, its actually a parent layout route
<Route path="/users" component={Users}>
<Route path="/:id" component={User} />
</Route>
jsx
<Route path="/users" component={Users} />
<Route path="/users/:id" component={User} />
jsx
<Route path="/users" component={Users} />
<Route path="/users/:id" component={User} />
jsx
<Route path="/users">
<Route path="/" component={Users} />
<Route path="/:id" component={User} />
</Route>
jsx
<Route path="/users">
<Route path="/" component={Users} />
<Route path="/:id" component={User} />
</Route>
