Simple web router for react that supports nested routes, data loaders and inline imports for code-splitting.

Examples

Using React.Supense and React.lazy

import { ComponentType, ComponentProps, lazy, Suspense } from "react";
import { RouterProvider, Outlet, Route } from "@shardbook/react-router";
import { Spinner } from "./Spinner";

// lazy loader function
function lazyLoad<T extends ComponentType<any>>(factory: () => Promise<{ default: T; }>) {
    const Component = lazy(factory);
    return (props: ComponentProps<T>) => (
        <Suspense fallback={<Spinner />}>
            <Component {...props} />
        </Suspense>
    );
}

const SignIn = lazyLoad(() => import("./SignIn"));
const SignUp = lazyLoad(() => import("./SignUp"));
const PageNotFound = lazyLoad(() => import("./PageNotFound"));
const PageError = lazyLoad(() => import("./PageError"));

const routes: Route[] = [
    {
        path: "/",
        element: <SignIn />,
    },
    {
        path: "/sign-up",
        element: <SignUp />,
    }
];

export default function App() {
    return (
        <RouterProvider
            routes={routes}
            noMatch={<PageNotFound />}
            error={(error) => <PageError error={error} />}
        >
            <Outlet setLocation fallback={<Spinner />} />
        </RouterProvider>
    );
}

It is always a good idea to wrap a lazy component inside a Suspense to let the user know that we're still importing it.

Using inline import

import { RouterProvider, Outlet, Route } from "@shardbook/react-router";
import { Spinner } from "./Spinner";

const PageNotFound = lazyLoad(() => import("./PageNotFound"));
const PageError = lazyLoad(() => import("./PageError"));

const routes: Route[] = [
    {
        path: "/",
        element: () => import("./SignIn"),
    },
    {
        path: "/sign-up",
        element: () => import("./SignUp"),
    }
];

export default function App() {
    return (
        <RouterProvider
            routes={routes}
            noMatch={<PageNotFound />}
            error={(error) => <PageError error={error} />}
        >
            <Outlet setLocation fallback={<Spinner />} />
        </RouterProvider>
    );
}

The router will import the component first before changing the location. You can use useRouter().loading to handle loading state.

With loader

// Dashboard.tsx
export default function Dashboard() {
    return <>Hello world!</>;
}

// User.tsx
export loader(config: any, params: any) {
    return fetch("/api/user" + params.userId, {
        headers: {
            "Authorization": "Bearer " + config.token
        }
    });
}

export default function User(props : { config: any; params: any; data: any; }) {
    return (
        <>
           config: {JSON.stringify(props.config)}
           userId: {props.params.userId}
           data: {JSON.stringify(props.data)}
        </>
    );
}

// Layout.tsx
import { Outlet, Link } from "@shardbook/react-router";
import { Spinner } from "./Spinner";

export default function Layout() {
    return (
        <>
            <header>
                <Link to="/">Dashboard</Link>
                <Link to="/my-user-id">User</Link>
            </header>

            <main>
                <Outlet setLocation fallback={<Spinner />} />
            </main>
        </>
    );
}

// App.tsx
import { RouterProvider, Route } from "@shardbook/react-router";

const PageNotFound = lazyLoad(() => import("./PageNotFound"));
const PageError = lazyLoad(() => import("./PageError"));

const routes: Route[] = [
    {
        path: "/",
        element: () => import("./Dashboard"),
    },
    {
        path: "/:userId",
        element: () => import("./User"),
    }
];

export default function App() {
    return (
        <RouterProvider
            routes={routes}
            noMatch={<PageNotFound />}
            error={(error) => <PageError error={error} />}
            config={{ token: "server-token" }}
        >
            <Layout />
        </RouterProvider>
    );
}

If your going to navigate to /my-user-id, the router will import the component with the loader first, then call the loader, waits for its response before changing the location. You can use useRouter().loading to handle loading state.

Components

  • RouterProvider - Routes controller.
  • Outlet - Route element renderer.
  • Link - A history-aware <a>.

Hooks

  • useRouter - Returns the current location and the loading path.
  • useNavigate - Returns an imperative function for route navigation.
