New features in React Router 7

  • ⚙️ How to install and set it up
  • 💻 Code examples using createBrowserRouter, loaders, layouts
  • 📦 Real-world use cases for Suspense and nested routing
  • 🤔 Developer Q&A and migration tips

Why React Router 7 is a Big Deal
React Router 7 supports the latest advancements in React — including Suspense, lazy loading, data loaders, and layout-based routing. It's designed to work seamlessly with React 18+ and future React 19 features.


🔍 Key Features in React Router 7

  • ✅ Built-in Suspense support for route-level code-splitting
  • ✅ Better nested routing via layouts
  • ✅ Loader and action support to fetch data before rendering
  • ✅ New hooks like useNavigation() and useRouteLoaderData()
  • ✅ Optimized support for modern rendering patterns

⚙️ Installation & Setup
Run the following to install:

npm install react-router-dom@7

Enter fullscreen mode Exit fullscreen mode

For a new app with Vite:

npm create vite@latest my-app --template react
cd my-app
npm install
npm install react-router-dom@7

Enter fullscreen mode Exit fullscreen mode

📦 Basic Router Example

import { createBrowserRouter, RouterProvider } from "react-router-dom";
import Home from "./pages/Home";
import About from "./pages/About";

const router = createBrowserRouter([
  { path: "/", element: <Home /> },
  { path: "/about", element: <About /> },
]);

function App() {
  return <RouterProvider router={router} />;
}

Enter fullscreen mode Exit fullscreen mode

🧱 Nested Routes with Layout

import RootLayout from "./layouts/RootLayout";
import Dashboard from "./pages/Dashboard";
import Profile from "./pages/Profile";

const router = createBrowserRouter([
  {
    path: "/",
    element: <RootLayout />,
    children: [
      { path: "dashboard", element: <Dashboard /> },
      { path: "profile", element: <Profile /> },
    ],
  },
]);

Enter fullscreen mode Exit fullscreen mode

React Router 7 makes layout nesting easier using its built-in child routes structure.


Preload Data with Loaders

// routes.js
{
  path: "user/:id",
  loader: async ({ params }) => {
    return fetchUser(params.id);
  },
  element: <UserProfile />
}

Enter fullscreen mode Exit fullscreen mode
// Inside UserProfile.jsx
import { useLoaderData } from "react-router-dom";

const UserProfile = () => {
  const user = useLoaderData();
  return <div>Welcome {user.name}</div>;
}

Enter fullscreen mode Exit fullscreen mode
