A React Router Extension Supporting Folder/File-Based Routing

react-router-file-routing is an extension of React Router DOM that supports folder/file-based routing, similar to the App Router in Next.js. It automatically generates routes based on folder structures with page.tsx files and allows easy management of dynamic and nested routes.

🛠 Installation

Before installing this library, make sure that react-router-dom and vite are already installed.

npm install react-router-file-routing react-router-dom
npm install -D vite

🚀 Usage

1. Basic Folder Structure

You must maintain the file structure in the format of src/pages/<route-name>/page.tsx to match the route. Each page.tsx file must have a default export.

src/
├── pages/
│   ├── page.tsx          // corresponds to the '/' route
│   ├── about/
│   │   └── page.tsx       // corresponds to the '/about' route
│   ├── blog/
│   │   ├── page.tsx       // corresponds to the '/blog' route
│   │   └── [postId]/
│   │       └── page.tsx   // corresponds to the '/blog/:postId' dynamic route
│   └── dashboard/
│       ├── page.tsx       // corresponds to the '/dashboard' route
│       └── settings/
│           └── page.tsx   // corresponds to the '/dashboard/settings' route

2. Using the FileRouter Component

The FileRouter component helps implement folder-based routing easily. By simply writing files according to the pages directory structure, routing will be handled automatically.

// src/App.tsx
import React from 'react';
import { FileRouter } from 'react-router-file-routing';

function App() {
  return <FileRouter />;
}

export default App;

3. Dynamic Routes

Use brackets ([ ]) in folder names to define dynamic routes. For example, a folder named [postId] will be interpreted as the route /blog/:postId.

// src/pages/blog/[postId]/page.tsx
import React from 'react';
import { useParams } from 'react-router-dom';

export default function BlogPostPage() {
  const { postId } = useParams<{ postId: string }>();
  return <h1>Blog Post: {postId}</h1>;
}

---

All Catch Router

You can define a Catch-all route by combining brackets ([ ]) and ... in folder names. For example, the folder /blog/[...slug] will be interpreted as /blog/* in React Router, and it will match multiple path segments.

Thus, paths like /blog/1, /blog/1/2, /blog/1/2/3, etc., will all render the same page.tsx.

Note: All Catch Routers have a lower priority than explicitly defined routes. This means that specific routes will be handled first, and the Catch-all route will handle any unmatched paths.

// src/pages/blog/[...slug]/page.tsx
import React from 'react';
import { useParams } from 'react-router-dom';

export default function BlogCatchAllPage() {
  const params = useParams<{ '*': string }>(); // wildcard matched route
  const slug = params['*'] ? params['*'].split('/') : []; // array of path segments

  return (
    <div>
      <h1>Blog Catch-All Page</h1>
      <p>Current Slug: {JSON.stringify(slug)}</p>
    </div>
  );
}

Usage Examples

• Accessing /blog/1 will result in slug = ['1'].
• Accessing /blog/1/2 will result in slug = ['1', '2'].
• Accessing /blog/1/2/3 will result in slug = ['1', '2', '3'].

With Catch-all routes, you can manage multiple levels of paths with a single component and dynamically handle different segments.

4. Layout Support

You can add a layout.tsx file inside a folder to apply a layout to the corresponding route. Layouts allow you to apply the same structure to nested routes.

// src/pages/dashboard/layout.tsx
import React from 'react';
import { Outlet } from 'react-router-dom';

export default function DashboardLayout() {
  return (
    <div>
      <h1>Dashboard</h1>
      <Outlet />
    </div>
  );
}

5. Group Routing Support

You can define a group route (or pathless route) using (folder-name) format.

• Ex.1
  • Folder: /pages/(root)/page.tsx, layout.tsx
  • Path: "/"
• Ex.2
  • Folder: /pages/home/(auth)/layout.tsx,page.tsx
  • Path: "/home"

6. Error Support

You can add an error.tsx file inside the folder to perform processing for errors in that path.
For more details, see errorElement in React Router

// src/pages/error.tsx
import { useRouteError } from 'react-router-dom';

export default function HomeError() {
  const error = useRouteError();
  console.log(error);

  return (
    <div className={styles.error}>
      <h1>Home Page Error</h1>
      <p>test</p>
    </div>
  );
}

7. Loading Support

You can add a loading.tsx file inside the folder to handle loading to that path.
For more information, see Suspense fallback in React

// src/pages/loading.tsx
export default function HomeLoading() {
  return (
    <div className={styles.wrapper}>
      <h1>Home Page Title</h1>
      <div className={styles.spinner} />
    </div>
  );
}

7. Loader Support

You can add a loader.ts file inside the folder to handle loader to that path.
For more information, see Loader in React Router

// src/pages/loader.ts
export default async function rootLoader() {
  const res = await fetch('https://swapi.dev/api/people');

  return await res.json();
}

// src/pages/layout.tsx
const data = useLoaderData();
