A complete routing library for React

React Router keeps your UI in sync with the URL. It has a simple API with powerful features like lazy code loading, dynamic route matching, and location transition handling built right in. Make the URL your first thought, not an after-thought.

Important: This is the master branch of React Router and may contain changes that are not yet released. To see the code for the most recently published release, browse the latest tag.

Browser Support

We support all browsers and environments where React runs.

Installation

Using npm:

$ npm install [email protected] react-router@latest

Note that you need to also install the history package since it is a peer dependency of React Router and won't automatically be installed for you in npm 3+.

Then with a module bundler like webpack that supports either CommonJS or ES2015 modules, use as you would anything else:

// using an ES6 transpiler, like babel
import { Router, Route, Link } from 'react-router'

// not using an ES6 transpiler
var Router = require('react-router').Router
var Route = require('react-router').Route
var Link = require('react-router').Link

The UMD build is also available on npmcdn:

<script src="https://npmcdn.com/react-router/umd/ReactRouter.min.js"></script>

You can find the library on window.ReactRouter.

What's it look like?

import React from 'react'
import { render } from 'react-dom'
import { Router, Route, Link } from 'react-router'

const App = React.createClass({/*...*/})
const About = React.createClass({/*...*/})
// etc.

const Users = React.createClass({
  render() {
    return (
      <div>
        <h1>Users</h1>
        <div className="master">
          <ul>
            {/* use Link to route around the app */}
            {this.state.users.map(user => (
              <li key={user.id}><Link to={`/user/${user.id}`}>{user.name}</Link></li>
            ))}
          </ul>
        </div>
        <div className="detail">
          {this.props.children}
        </div>
      </div>
    )
  }
})

const User = React.createClass({
  componentDidMount() {
    this.setState({
      // route components are rendered with useful information, like URL params
      user: findUserById(this.props.params.userId)
    })
  },

  render() {
    return (
      <div>
        <h2>{this.state.user.name}</h2>
        {/* etc. */}
      </div>
    )
  }
})

// Declarative route configuration (could also load this config lazily
// instead, all you really need is a single root route, you don't need to
// colocate the entire config).
render((
  <Router>
    <Route path="/" component={App}>
      <Route path="about" component={About}/>
      <Route path="users" component={Users}>
        <Route path="/user/:userId" component={User}/>
      </Route>
      <Route path="*" component={NoMatch}/>
    </Route>
  </Router>
), document.body)

Thanks

Thanks to our sponsors for supporting the development of React Router.

React Router was initially inspired by Ember's fantastic router. Many thanks to the Ember team.

Also, thanks to BrowserStack for providing the infrastructure that allows us to run our build in real browsers.
