React Router

Getting Started

Before continuing, make sure to configure:

Tailwind CSS 4.

Installation

npm i fumadocs-core fumadocs-ui fumadocs-mdx @types/mdx

Then, configure Fumadocs MDX on your React Router app. Make sure essential files like lib/source.ts are created correctly.

Styles

Add the following to your Tailwind CSS file:

app/app.css

@import 'tailwindcss';
@import 'fumadocs-ui/css/neutral.css';
@import 'fumadocs-ui/css/preset.css';

Create Pages

Update your routes:

routes.ts

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

export default [
  index('routes/home.tsx'),
  route('docs/*', 'docs/page.tsx'),
  route('api/search', 'docs/search.ts'),
] satisfies RouteConfig;

Create the following files:

import type { BaseLayoutProps } from 'fumadocs-ui/layouts/shared';

export function baseOptions(): BaseLayoutProps {
  return {
    nav: {
      title: 'React Router',
    },
  };
}

Wrap your entire app under Fumadocs providers:

root.tsx

import { Links, Meta, Scripts, ScrollRestoration } from 'react-router';
import { RootProvider } from 'fumadocs-ui/provider/base';
import { ReactRouterProvider } from 'fumadocs-core/framework/react-router';
import './app.css';

export function Layout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en" suppressHydrationWarning>
      <head>
        <meta charSet="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <Meta />
        <Links />
      </head>
      <body className="flex flex-col min-h-screen">
        <ReactRouterProvider>
          <RootProvider>{children}</RootProvider>
        </ReactRouterProvider>
        <ScrollRestoration />
        <Scripts />
      </body>
    </html>
  );
}

Done
