Important Notes

SemVer

Before our 1.0 release, breaking API changes will cause a bump to 0.x. For example, 0.4.1 and 0.4.8 will have the same API, but 0.5.0 will have breaking changes.

Please refer to the upgrade guide and changelog when upgrading.

Installation

npm install react-router
# or
bower install react-router

This library is written with CommonJS modules. If you are using browserify, webpack, or similar, you can consume it like anything else installed from npm.

There is also a global build available on bower, find the library on window.ReactRouter.

The library is also available on the popular CDN cdnjs.

Features

  • Nested views mapped to nested routes
  • Modular construction of route hierarchy
  • Sync and async transition hooks
  • Transition abort / redirect / retry
  • Dynamic segments
  • Query parameters
  • Links with automatic .active class when their route is active
  • Multiple root routes
  • Hash or HTML5 history (with fallback) URLs
  • Declarative Redirect routes
  • Declarative NotFound routes
  • Browser scroll behavior with transitions

Check out the examples directory to see how simple previously complex UI and workflows are to create.

What's it look like?

var routes = (
  <Route handler={App} path="/">
    <DefaultRoute handler={Home} />
    <Route name="about" handler={About} />
    <Route name="users" handler={Users}>
      <Route name="recent-users" path="recent" handler={RecentUsers} />
      <Route name="user" path="/user/:userId" handler={User} />
      <NotFoundRoute handler={UserRouteNotFound}/>
    </Route>
    <NotFoundRoute handler={NotFound}/>
    <Redirect from="company" to="about" />
  </Route>
);

Router.run(routes, function (Handler) {
  React.render(<Handler/>, document.body);
});

// Or, if you'd like to use the HTML5 history API for cleaner URLs:

Router.run(routes, Router.HistoryLocation, function (Handler) {
  React.render(<Handler/>, document.body);
});

See more in the overview guide.

Benefits of this Approach

  1. Incredible screen-creation productivity - There is only one use-case when a user visits a route: render something. Every user interface has layers (or nesting) whether it's a simple navbar or multiple levels of master-detail. Coupling nested routes to these nested views gets rid of a ton of work for the developer to wire all of it together when the user switches routes. Adding new screens could not get faster.

  2. Immediate understanding of application structure - When routes are declared in one place, developers can easily construct a mental image of the application. It's essentially a sitemap. There's not a better way to get so much information about your app this quickly.

  3. Code tractability - When a developer gets a ticket to fix a bug at as specific url they simply 1) look at the route config, then 2) go find the handler for that route. Every entry point into your application is represented by these routes.

  4. URLs are your first thought, not an after-thought - With React Router, you don't get UI on the page without configuring a url first. Fortunately, it's wildly productive this way, too.

Thanks, Ember

This library is highly inspired by the Ember.js routing API. In general, it's a translation of the Ember router api to React. Huge thanks to the Ember team for solving the hardest part already.
