react-resource-router

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.

$3

- 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

$3

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

``js
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'),
});
`

$3

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.

`js
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 ;
}

if (loading) {
return ;
}

return

`js
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],
},
];
`

$3

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!

`js
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 = () => (



);
`

Installation

npm install react-resource-router

or

yarn add react-resource-router
`
