Learn Routing in React with React Router v6

What is Routing in React and React Router v6

React Router is a client-side routing package, which lets React applications navigate between components depending on the URL and without reloading the page. This improves user experience because navigating becomes easier and quicker. React Router v6 is an update that comes with a few enhancements compared to the earlier ones, like the ease of configuration of the routes, enhancement of nested routing, and the path matching routines.

In principle, the React Router v6 incorporates the <BrowserRouter> element that facilitates handling the history and matching the URL. Within it, <Routes> components organize single nodes of <Route>, which designate the path and grouping component to show. This is declarative and hence routes are easy to maintain and organize.

Installation of React Router v6 into your Project

In order to be able to use React Router v6, you have to download it using npm first:

npm install react-router-dom 6

All the requirements of web routing such as core components and hooks are all brought together in this one single package. Once installed, then import the components that you will need to define routes, in your root file, e.g. `.main.jsx` or `App.js`.

Key Learning in React Router v6

The Route Matching and Route Parts

The current algorithm used by react router v6 is simpler in its approach as it follows the ranking PATH matching algorithm. Connections that have more determinable paths usurp prior to connections that have less determinable paths. This aids in avoiding the rendering of several components and also it causes predictability in the UI behavior.

The current <Route> no longer has component or render props but instead has the element prop which you specify the JSX component to render.

Nested Routing

Nested routing is one of the powerful parts of React Router, where the components can be paths of another path. This comes handy in cases of layouts or nested UI objects. React Router v6 provides a simplified solution by nesting <Route> elements within parent routes, thus allowing nested UI creation and manipulation to be easier to deal with.

<Routes>

Route path="/">element={<Layout />}>

Route index element ={ <Home /> }

Route path="/about" element={<About />} />

</Route>

</Routes>

URL parameters and dynamic Routes

Dynamic routing is possible in React Router with parameters in the route path, e.g. /profile/:userId. The useParams() hook is located in components to retrieve route parameters. For example:

import { useParams } from react-router-dom;

function Profile(){

const { userId } = useParams;

res <div>User Profile of {userId}</div>;

}

This structure allows creation of personalised data-driven pages.

Since the home page is not in a script, it has to be programmed to navigate through the pages, commonly referred to as navigation. The navigation process is then programmed in another page known as programmatic routing.

React Router v6 provides the useNavigate() hook so that one can programmatically navigate, which is convenient in case one needs to redirect after the form was sent or an authentication process.

Example:

import { useNavigate } from react-router-dom;

function Login(){

const navigate = useNavigate();

function login() {

// Logon functionality

navigate('/dashboard');

}

return

}

Improvements and new features of React Router v6.4 and higher

Introduced in 6.4 and subsequent versions, the routing capabilities which can be classified as even more powerful, provide the data loading APIs which can make the data related to route easy to load prior to rendering, built-in error handling routes, and better route loaders. The features optimize complicated UI states and enhance performances since everything required is loaded prior to the rendering of a page.
