The Push to Ban Ransom Payments Is Gaining Momentum
Ransomware costs victims an estimated $30 billion per year and has gotten so out of control that global support for banning payments is gaining momentum.

Package description
The react-router npm package is a declarative routing library for React, allowing you to add navigation functionality to your React applications. It enables you to handle URL routing, match routes to your React components, and manage navigation state in a single-page application (SPA) environment.
Basic Routing
This code demonstrates how to set up basic routing in a React application using react-router. It includes navigation links and route components that render different components based on the URL path.
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
function App() {
return (
<Router>
<div>
<nav>
<ul>
<li>
<Link to='/'>Home</Link>
</li>
<li>
<Link to='/about'>About</Link>
</li>
</ul>
</nav>
<Route exact path='/' component={Home} />
<Route path='/about' component={About} />
</div>
</Router>
);
}
function Home() {
return <h2>Home</h2>;
}
function About() {
return <h2>About</h2>;
}
Dynamic Routing
This code snippet shows how to implement dynamic routing with path parameters. The User component will render with the appropriate user ID based on the URL.
import { BrowserRouter as Router, Route, Link } from 'react-router-dom';
function App() {
return (
<Router>
<div>
<ul>
<li>
<Link to='/users/1'>User 1</Link>
</li>
<li>
<Link to='/users/2'>User 2</Link>
</li>
</ul>
<Route path='/users/:id' component={User} />
</div>
</Router>
);
}
function User({ match }) {
return <h2>User ID: {match.params.id}</h2>;
}
Nested Routing
Nested routing allows you to create routes within routes. This example shows a Layout component with a nested Dashboard route.
import { BrowserRouter as Router, Route, Link, Switch } from 'react-router-dom';
function App() {
return (
<Router>
<Route path='/' component={Layout} />
</Router>
);
}
function Layout({ match }) {
return (
<div>
<nav>
<Link to={`${match.url}dashboard`}>Dashboard</Link>
</nav>
<Switch>
<Route path={`${match.path}dashboard`} component={Dashboard} />
</Switch>
</div>
);
}
function Dashboard() {
return <h2>Dashboard</h2>;
}
Protected Routes
Protected routes are used to restrict access to certain parts of your application. This example shows a route that renders a component only if the user is authenticated, otherwise it redirects to a login page.
import { BrowserRouter as Router, Route, Redirect } from 'react-router-dom';
function App() {
return (
<Router>
<Route path='/protected' render={() => (
isAuthenticated() ? (
<ProtectedComponent />
) : (
<Redirect to='/login' />
)
)} />
</Router>
);
}
function isAuthenticated() {
// Authentication logic here
return true;
}
function ProtectedComponent() {
return <h2>Protected</h2>;
}
Vue-router is the official router for Vue.js. It provides similar functionalities for Vue applications as react-router does for React applications, including nested routes, dynamic segments, and navigation guards. However, it is designed to work seamlessly with Vue's reactivity system.
Angular's router is a powerful navigation library for Angular applications. It offers features like lazy loading, nested routes, and data resolvers. While it provides similar routing capabilities, it is tailored to the Angular framework and uses a different syntax and set of concepts compared to react-router.
Reach Router is another routing library for React, which aims to be more accessible and simpler to use than react-router. It has a smaller API surface area and focuses on accessibility by managing focus after route transitions. However, as of my knowledge cutoff in 2023, Reach Router has been officially merged with React Router, and its features have been integrated into React Router v6.
Next.js comes with its own routing capabilities built-in, provided by next/router. It supports dynamic routes, shallow routing, and server-side rendering. Unlike react-router, which is client-side routing, Next.js handles routing on both the client and server, enabling hybrid static and server rendering.
Readme
Declarative routing for React.
Using npm:
$ npm install --save react-router
Note: This package provides the core routing functionality for React Router, but you might not want to install it directly. If you are writing an application that will run in the browser, you should instead install react-router-dom
. Similarly, if you are writing a React Native application, you should instead install react-router-native
. Both of those will install react-router
as a dependency.
Then with a module bundler like webpack, use as you would anything else:
// using ES6 modules
import { Router, Route, Switch } from "react-router";
// using CommonJS modules
var Router = require("react-router").Router;
var Route = require("react-router").Route;
var Switch = require("react-router").Switch;
The UMD build is also available on unpkg:
<script src="https://unpkg.com/react-router/umd/react-router.min.js"></script>
You can find the library on window.ReactRouter
.
If you find a bug, please file an issue on our issue tracker on GitHub.
