React Router Home

React Router is a multi-strategy router for React bridging the gap from React 18 to React 19. You can use it maximally as a React framework or minimally as a library with your own architecture.

If you are caught up on future flags, upgrading from React Router v6 or Remix is generally non-breaking:

React Router as a Library

Like previous versions, React Router can still be used as a simple, declarative routing library. Its only job will be matching the URL to a set of components, providing access to URL data, and navigating around the app.

This strategy is popular for "Single Page Apps" that have their own frontend infrastructure and v6 apps looking for a stress free upgrade.

It's particularly good at offline + sync architectures where pending states are rare and users have long running sessions. Framework features like pending states, code splitting, server rendering, SEO, and initial page load times can be traded out for instant local-first interactions.

ReactDOM.createRoot(root).render(
  <BrowserRouter>
    <Routes>
      <Route path="/" element={<Home />} />
      <Route path="dashboard" element={<Dashboard />}>
        <Route index element={<RecentActivity />} />
        <Route path="project/:id" element={<Project />} />
      </Route>
    </Routes>
  </BrowserRouter>
);

React Router as a framework

React Router can be used maximally as your React framework. In this setup, you'll use the React Router CLI and Vite bundler plugin for a full-stack development and deployment architecture. This enables React Router to provide a large set of features most web projects will want, including:

Vite bundler and dev server integration
hot module replacement
code splitting
route conventions with type safety
file system or config-based routing
data loading with type safety
actions with type safety
automatic revalidation of page data after actions
SSR, SPA, and static rendering strategies
APIs for pending states and optimistic UI
deployment adapters

Routes are configured with routes.ts which enables React Router to do a lot for you. For example, it will automatically code-split each route, provide type safety for the parameters and data, and automatically load the data with access to pending states as the user navigates to it.

import {
  type RouteConfig,
  route,
  index,
  layout,
  prefix,
} from "@react-router/dev/routes";

export default [
  index("./home.tsx"),
  route("about", "./about.tsx"),

  layout("./auth/layout.tsx", [
    route("login", "./auth/login.tsx"),
    route("register", "./auth/register.tsx"),
  ]),

  ...prefix("concerts", [
    index("./concerts/home.tsx"),
    route(":city", "./concerts/city.tsx"),
    route(":city/:id", "./concerts/show.tsx")
    route("trending", "./concerts/trending.tsx"),
  ]),
] satisfies RouteConfig;

You'll have access to the Route Module API, which most of the other features are built on.

Loaders provide data to route components:

// loaders provide data to components
export async function loader({ params }: Route.LoaderArgs) {
  const [show, isLiked] = await Promise.all([
    fakeDb.find("show", params.id),
    fakeIsLiked(params.city),
  ]);
  return { show, isLiked };
}

Components render at their configured URLs from routes.ts with the loader data passed in as a prop:

export default function Show({
  loaderData,
}: Route.ComponentProps) {
  const { show, isLiked } = loaderData;
  return (
    <div>
      <h1>{show.name}</h1>
      <p>{show.description}</p>

      <form method="post">
        <button
          type="submit"
          name="liked"
          value={isLiked ? 0 : 1}
        >
          {isLiked ? "Remove" : "Save"}
        </button>
      </form>
    </div>
  );
}

Actions can update data and trigger a revalidation of all data on the page so your UI stays up to date automatically:

export async function action({
  request,
  params,
}: Route.LoaderArgs) {
  const formData = await request.formData();
  await fakeSetLikedShow(formData.get("liked"));
  return { ok: true };
}

Route modules also provide conventions for SEO, asset loading, error boundaries, and more.
