🚀 React Router v4 - How to get current route?

Are you struggling to pass the current route as a prop to the <AppBar /> component in React Router v4? Don't worry, I've got you covered! In this guide, I'll show you how to easily retrieve the current route and pass it to the desired component. Let's dive in! 😎

🧐 Understanding the Problem

To provide a dynamic title for the <AppBar /> component based on the current route, we need a way to access the current route within the component. In React Router v4, the route information is not directly available as a prop. So, how can we solve this problem? 🤔

💡 The Solution - withRouter

The solution lies in using the withRouter higher-order component provided by the React Router library. By wrapping our component with withRouter, we can access the current route information through the location prop. Let's see how it works!

First, import the withRouter function from React Router:

import { withRouter } from 'react-router-dom';

Next, wrap your component with the withRouter higher-order component:

const AppBarWithRouter = withRouter(AppBar);

Now, the AppBarWithRouter component has access to the location prop, which contains the current route information. You can now use this prop to dynamically modify the title.

🚀 Implementing the Solution

Let's update the code snippet you provided to demonstrate how to pass the current route as the title prop to the <AppBar /> component:

import React from 'react';
import { BrowserRouter as Router, Route, withRouter } from 'react-router-dom';

const AppBar = ({ title, location }) => {
  // Modify the title based on the current route
  const currentRoute = location.pathname;
  const modifiedTitle = `Current Route: ${currentRoute}`;

  return (
    <div>
      <h1>{modifiedTitle}</h1>
    </div>
  );
};

const AppBarWithRouter = withRouter(AppBar);

const App = () => {
  return (
    <Router basename="/app">
      <main>
        <AppBarWithRouter />
        <Route path="/customers" component={Customers} />
      </main>
    </Router>
  );
};

In the updated code snippet, we've wrapped the AppBar component with withRouter to gain access to the location prop. We then modified the title prop by appending the current route to it. Finally, we rendered <AppBarWithRouter /> in the <App /> component.

🚀 Try It Out!

Save the modifications, run your app, and navigate to different routes. You should now see the current route being displayed as the title in the <AppBar /> component. How cool is that? 😄

📣 Call-to-Action

React Router v4 provides great functionality to handle routes in your React application. By using the withRouter higher-order component, you can easily access the current route and pass it to any desired component. Give it a try and unleash the power of dynamic routes in your app!
