React Router | Installation
Installation
This document describes the most park ways people use react Router with versatile tools in the React Ecosystem .
Basic Installation
Most advanced React projects manage their dependencies using a software director like npm or Yarn. To add React Router to an existing project, the beginning thing you should do is install the necessary dependencies with the joyride of your choice :
npm
$ npm install react-router-dom @ 6Yarn
$ yarn add react-router-dom @ 6 Reading: React Router | Installation
pnpm
$ pnpm add react-router-dom @ 6Create React App
Follow the instructions in the React documentation to set up a new project with Create React App, then follow the installation instructions above to install React Router in your stick out. once your project is set up and React Router is installed as a dependence, open the src/index.js in your textbook editor program. Import BrowserRouter from react-router-dom near the top of your file and wrap your app in a
import
*
as
React
from
`` react
`` ; import
ReactDOM
from
`` react-dom/client
`` ; import
{ BrowserRouter
} from
`` react-router-dom
`` ; import
`` ./index.css
`` ; import
App
from
`` ./App
`` ; import
reportWebVitals
from
`` ./reportWebVitals
`` ; const
root
=
ReactDOM
. createRoot
( document
. getElementById
( `` root
`` ) ) ; root
. render
( < React.StrictMode
> < BrowserRouter
> < App
/ > < p BrowserRouter>
< p React.StrictMode>
) ; nowadays you can use react Router anywhere in your app ! For a simpleton case, open src/App.js and replace the default markup with some routes :
import
*
as
React
from
`` react
`` ; import
{ Routes
, Route
, Link
} from
`` react-router-dom
`` ; import
`` ./App.css
`` ; function
App
( ) { return
( < div
className
=
`` App
`` > < h1
> Welcome to React Router ! < phosphorus h1>
<
Routes
> <
Route
path
=
“
/
“
element
=
{
<
Home
/ >
}
/ > <
Route
path
=
“
about
“
element
=
{
<
About
/ >
}
/ > < phosphorus Routes>
< phosphorus div>
) ; } now, still in src/App.js, create your route components :
// App.js
function
Home
( ) { return
( < > < main
> < h2
> Welcome to the home page ! < phosphorus h2>
<
p
> You can do this, I believe in you. < phosphorus phosphorus>
< phosphorus main>
<
nav
> <
Link
to
=
“
/about
“ > About < p Link>
< phosphorus nav>
) ; }
function
About
( ) {
return
( < > <
main
> <
h2
> Who are we ? < phosphorus h2>
<
p
> That feels like an existential question, do n’t you think ? < phosphorus p>
< p main>
<
nav
> <
Link
to
=
“
/
“ > Home < p Link>
< p nav>
) ; } Go ahead and start your app by running npm start, and you should see the Home path when your app starts running. Click the “ About ” radio link to see your
Parcel
Follow the instructions in the Parcel documentation to set up a modern project, then follow the initiation instructions above to install React Router in your undertaking. In your undertaking ‘s package.json, add a start script so you can open your project in a browser during development .
`` scripts
`` : { `` start
`` : `` parcel index.html
`` } once the project is set up and your dependencies are installed, create a new .babelrc file at the root of your project :
{ `` presets
`` : [ `` @babel/preset-react
`` ] } Go to the index.js file in your project and import the necessary functions from react, react-dom, and react-router-dom and mount a React app in a div with the ID of root :
// index.js
import
*
as
React
from
`` react
`` ; import
ReactDOM
from
`` react-dom/client
`` ; import
{ BrowserRouter
} from

`` react-router-dom
`` ; import
App
from
`` ./App.js
`` ; const
root
=
ReactDOM
. createRoot
( document
. getElementById
( `` root
`` ) ) ; root
. render
( < React.StrictMode
> < BrowserRouter
> < App
/ > < phosphorus BrowserRouter>
< p React.StrictMode>
) ; In your index.html, create the root div in the document soundbox above the script tag. It’s besides helpful to provide a noscript disengagement message for users who may have disabled JavaScript, unless you plan on server-rendering your app belated .
< body
> < noscript
> You need to enable JavaScript to run this app. < phosphorus noscript
> <
div
id
= ''
root
`` > < phosphorus div>
<
script
src

./index.js
`` > < phosphorus script>

immediately that React and React Router are set up create a new charge App.js and add some routes and components :
// App.js
import
*
as
React
from
`` react
`` ; import
{ Routes
, Route
, Link
} from
`` react-router-dom
`` ; function
App
( ) { return
( < div
> < header
> < h1
> Welcome to React Router ! < p h1>
< p heading>
<
Routes
> <
Route
path
=
``
/
``
element
=
{
<
Home
/ >
}
/ > <
Route
path
=
``
about
``
element
=
{
<
About
/ >
}
/ > < p Routes>
< phosphorus div>
) ; }
function
Home
( ) {
return
( < > <
main
> <
h2
> Welcome to the home page ! < p h2>
<
p
> You can do this, I believe in you. < phosphorus p>
< p main>
<
nav
> <
Link
to
=
``
/about
`` > About < phosphorus Link>
< phosphorus nav>
) ; }
function
About
( ) {
return
( < > <
main
> <
h2
> Who are we ? < p h2>
<
p
> That feels like an existential wonder, do n't you think ? < phosphorus p>
< p main>
<
nav
> <
Link
to
=
``
/
`` > Home < p Link>
< p nav>
) ; }
export
default
App
; now start your app by running npm start, and you should see the Home path when your app starts running. Click the `` About '' link to see your About route, and voilà ! You successfully set up React Router using Parcel ! 🥳
Webpack
Follow the instructions in the webpack documentation to set up a raw project, then follow the initiation instructions above to install React Router in your project. Setting up a new React project in webpack is a bit more involve than Parcel or Create React App. Because webpack is a subordinate tool that allows you to fine-tune your construct to your like, you may want to read the webpack software documentation or check out webpack configurations in other repos to understand how to build your own. once you have webpack configured and the necessity dependencies installed, somewhere in your code ( credibly towards the root of your React component corner ) you can import the modules you need from react-router-dom .
import
{ BrowserRouter
, Routes
, Route
, } from
`` react-router-dom
`` ; function
App
( ) { return
( < BrowserRouter
> < div
> < h1
> Hello, React Router ! < phosphorus h1>
<
Routes
> <
Route
path
=
``
/
``
element
=
{
<
Home
/ >
}
/ > < p Routes>
< phosphorus div>
< phosphorus BrowserRouter
>
) ; } One of the quickest ways to add React and React Router to a web site is to use good ol '
