React Resource Router (RRR) is a configuration driven routing solution for React that manages single page application route matching, data fetching and progressive rendering.

Why?

React Resource Router was developed by Atlassian for Jira primarily to improve performance and prepare for compatibility with React's forthcoming Concurrent Mode on both client and server. You can read more about its development and impact here.

Features

• Fully driven by a static configuration of route objects
• Each route object contains the following core properties
  • path - the path to match
  • component - the component to render
  • resources - an array of objects containing fetch functions that request the route component's data
• Data for a route is requested asynchronously and as early as possible, with the page progressively rendering as the requests resolve. This results in quicker meaningful render times
• Works on both client and server without having to traverse the React tree

Usage

Create your resources

Resources describe and provide the data required for your route. This data is safely stored and accessed via the useResource hook or ResourceSubscriber component.

import { createResource } from 'react-resource-router/resources';
import { fetch } from '../common/utils';

export const homeResource = createResource({
  type: 'HOME',
  getKey: () => 'home-resource-key',
  getData: () => fetch('https://my-api.com/home'),
});

export const aboutResource = createResource({
  type: 'ABOUT',
  getKey: () => 'about-resource-key',
  getData: () => fetch('https://my-api.com/about'),
});

Create your components

These are the React components that get rendered for your routes. As mentioned, they can be wired into the state of your resources via the useResource hook or ResourceSubscriber component.

import { useResource } from 'react-resource-router/resources';
import { aboutResource, homeResource } from '../routes/resources';
import { Loading, Error } from './common';

export const Home = () => {
  const { data, loading, error } = useResource(homeResource);

  if (error) {
    return <Error error={error} />;
  }

  if (loading) {
    return <Loading />;
  }

  return <div>{data.home.content}</div>;
};

export const About = () => {
  const { data, loading, error } = useResource(aboutResource);

  if (error) {
    return <Error error={error} />;
  }

  if (loading) {
    return <Loading />;
  }

  return <div>{data.about.content}</div>;
};

Create your routes

Your route configuration is the single source of truth for your application's routing concerns.

import { Home, About } from '../components';
import { homeResource, aboutResource } from './resources';

export const appRoutes = [
  {
    name: 'home',
    path: '/',
    exact: true,
    component: Home,
    resources: [homeResource],
  },
  {
    name: 'about',
    path: '/about',
    exact: true,
    component: About,
    resources: [aboutResource],
  },
];

Use the Router

Now that you've set up your resources, components and configuration correctly, all you need to do is mount the Router in your react tree with a RouteComponent as a child. It will do the rest!

import {
  Router,
  RouteComponent,
  createBrowserHistory,
} from 'react-resource-router';
import { createResourcesPlugin } from 'react-resource-router/resources';
import { appRoutes } from './routing/routes';

const history = createBrowserHistory();
const resourcesPlugin = createResourcesPlugin({});

const App = () => (
  <Router routes={appRoutes} history={history} plugins={[resourcesPlugin]}>
    <RouteComponent />
  </Router>
);

Installation
