How to Change the Base Path in React

Last updated on March 3, 2023 A Goodman Loading... One comment

This short and straight-to-the-point article shows you how to set a base path for a React app created with create-react-app and using React Router.

The Prefatory Matter

There might be situations where you want to run your React app with a base path (a URL prefix for all routes), such as your app is served from a subdirectory on your server, or you deploy multiple apps under a single domain.

These are some common real-world use cases:

The Solution

To configure the base URL, set the basename prop of the <BrowserRouter> component (imported from react-router-dom) to a string, like so:

import { BrowserRouter, Routes, Route } from 'react-router-dom'

function App() {
  return (
    <BrowserRouter basename='/your-subdirectory'>
       {/* ... */}

basename will be automatically added to every route of your app.

Before building your project for production, open the package.json file and add this line:

"homepage": "/your-subdirectory",

Here’s mine:

This will make sure that all the asset paths are relative to the index.html file when you deploy your build in the your-subdirectory folder (in my case, it is kindacode).


This example uses React Router v6 (the latest one). The tiny app we’re going to make has two routes:

  • /: Home
  • /sample: SamplePage

The base path is /kindacode. Here’s how it works:

And here is the complete source code that produces our example:

// src/App.js
import { BrowserRouter, Routes, Route, Link } from 'react-router-dom'

function App() {
  return (
    <BrowserRouter basename='/kindacode'>
        <Route path='/' element={<HomePage />} />
        <Route path='/sample' element={<SamplePage />} />

// Home page
const HomePage = () => {
  return <div style={{padding: 30}}>
    <h1>Home Page</h1>
    <p><Link to="/sample">Go to Sample page</Link></p>

// Sample Page
const SamplePage = () => {
  return <div style={{padding: 30}}>
    <h1>Sample Page</h1>

export default App;

Hello Kindacode, the above method is adding “basename” to assets, no doubt. But how we can use the basename to pages’ links?
Should we use before each link something like $base_url ?
