React Router DOM

• A single-page application built with React uses routing to achieve page jumps.
• In React, the commonly used two packages can achieve this demand, that is, react-router and react-router-dom.

React Router DOM

• Based on react-router, some functions in the browser operating environment have been added.
• react-router-dom depends on react-router.

	npm install react-router-dom
yarn add react-router-dom
	

			
	
			

		
	

Components in React Router

Router: <BrowserRouter> and <HashRouter>
Route Matcher: <Route> and <Switch>
Route Changer:<Link> , <NavLink> and <Redirect>

Router

The Main Difference between is <BrowserRouter> and <HashRouter>

• How the way they store URLs and communicate with the webserver.

• To use a router, make sure to present it at the root of the element

	import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";

const App = () => (
  <h1>Hello World!!</h1>
);

ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById("root")
);

	

			
	
			

		
	

Route Matcher

When <Switch> renders, it will search its children <Route> contents to find a path that matches the current URL.

	import React from "react";
import ReactDOM from "react-dom";

import {
  BrowserRouter,
  Switch,
  Route
} from "react-router-dom";

const Contact = () => <div>Contact US</div>;

const App = () => (
  <BrowserRouter>
    <Switch>
      <Route path="/contact" component={Contact}></Route>
    </Switch>
  </BrowserRouter>
);

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

	

			
	
			

		
	

Route Changer

• <Link> component to create a link in the application.
• <Redirect> use when forced navigation.
• <NavLink> It is a special type <Link> that will add style parameters.

	<div>
  <Link to="/">Contact</Link>
  <NavLink to="/contact2" activeClassName="name">
    React
  </NavLink>
  <Redirect to="/signup" />
</div>;
