Introduction
In this post, I am going to talk about how to implement routing
in your react applications with react-router-dom. I will explain how to implement routing as well as passing data around in your components. (I expect you to have react-development-environment on your computer as a prerequisite.)

Install react-router-dom
You can install react-router-dom
by running the command below.
$ npm install react-router-dom
Setting up the links
First and foremost, import Link
from react-router-dom
and create links that are connected with designated paths.
For instance, if a user clicks Home
in the code below, the user will be transferred to the '/' page and if a user clicks About
, the user will be sent to the /About
page.
import React from 'react'
import { Link } from 'react-router-dom'
class Navbar extends React.Component {
render(){
return(
<div>
<Link to="/">Home</Link>
<Link to="/About">About</Link>
</div>
)
}
}
export default Navbar;
Setting up Router and Route
All you gotta do to connect one page to another in your react app is connecting the paths and components using Router
and Route
.
There really are only two things you should keep in your mind.
-
Routes
must be defined inRouters
. - Write the path and the corresponding component in each
Route
import React, { Component } from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import Navbar from './Navbar';
import About from './About';
import Home from './Home';
class App extends Component {
render() {
return (
<div className="App">
<Router>
<div>
<Navbar /><hr/>
<Route exact path='/' component={Home}/>
<Route path='/About' component={About}/>
</div>
</Router>
</div>
);
}
}
export default App;
Passing data with props
You can accomplish this very easily by writing Route
element like the code below.
class App extends Component {
render() {
return (
<div className="App">
<Router>
<div>
<Navbar /><hr/>
<Route exact path='/' component={Home}/>
<Route path='/About' render={ () => <About name={'Tom'}/> }/>
</div>
</Router>
</div>
);
}
}
export default App;
You can get the data in About
component like the code below.
import React from 'react'
class About extends React.Component {
render(){
return(
<div>
<h1>About</h1>
<h2>I am {this.props.name}</h2>
</div>
)
}
}
export default About;
