Nested Routes

Nested routing helps us to render the sub-routes like users/1, users/2 etc.

index.js

import React from 'react'
import ReactDOM from 'react-dom'
import './index.css'
import { Route, Link, BrowserRouter as Router, Switch } from 'react-router-dom'
import App from './App'
import Users from './users'
import Contact from './contact'
import Notfound from './notfound'

const routing = (
  <Router>
    <div>
      <ul>
        <li>
          <Link to="/">Home</Link>
        </li>
        <li>
          <Link to="/users">Users</Link>
        </li>
        <li>
          <Link to="/contact">Contact</Link>
        </li>
      </ul>
      <hr />
      <Switch>
        <Route exact path="/" component={App} />
        <Route exact path="/users" component={Users} />
        <Route path="/contact" component={Contact} />
        <Route component={Notfound} />
      </Switch>
    </div>
  </Router>
)
ReactDOM.render(routing, document.getElementById('root'))

How to implement a nested routing?

In the users.js file, we need to import the react router components because we need to implement the subroutes inside the Users Component.

users.js

import React from 'react'
import { Route, Link } from 'react-router-dom'

const User = ({ match }) => <p>{match.params.id}</p>

class Users extends React.Component {
  render() {
    const { url } = this.props.match
    return (
      <div>
        <h1>Users</h1>
        <strong>select a user</strong>
        <ul>
          <li>
            <Link to="/users/1">User 1 </Link>
          </li>
          <li>
            <Link to="/users/2">User 2 </Link>
          </li>
          <li>
            <Link to="/users/3">User 3 </Link>
          </li>
        </ul>
        <Route path="/users/:id" component={User} />
      </div>
    )
  }
}

export default Users
