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 inslug = ['1']
. - Accessing
/blog/1/2
will result inslug = ['1', '2']
. - Accessing
/blog/1/2/3
will result inslug = ['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();
