Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
react-router
Advanced tools
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.
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.
The react-router
package is the heart of React Router and provides all
the core functionality for both
react-router-dom
and
react-router-native
.
If you're using React Router, you should never import
anything directly from
the react-router
package, but you should have everything you need in either
react-router-dom
or react-router-native
. Both of those packages re-export
everything from react-router
.
If you'd like to extend React Router and you know what you're doing, you should
add react-router
as a peer dependency, not a regular dependency in your
package.
v6.10.0
Date: 2023-03-29
We recently published a post over on the Remix Blog titled "Future Proofing Your Remix App" that goes through our strategy to ensure smooth upgrades for your Remix and React Router apps going forward. React Router 6.10.0
adds support for these flags (for data routers) which you can specify when you create your router:
const router = createBrowserRouter(routes, {
future: {
// specify future flags here
},
});
You can also check out the docs here and here.
