Demystifying the Issue with useNavigate and useBlocker in createBrowserRouter Setup

Are you tired of encountering issues with useNavigate and useBlocker in your createBrowserRouter setup? You’re not alone! Many React Router enthusiasts have stumbled upon this frustrating problem, but fear not, dear developer, for we’re about to dive into the solution.

Understanding the Problem

Before we dive into the solution, let’s first understand the issue at hand. When using createBrowserRouter, you might have noticed that useNavigate and useBlocker don’t work as expected. This can be attributed to the way these hooks interact with the router’s history.

The useNavigate hook allows you to programmatically navigate to a new location, while useBlocker enables you to block navigation when certain conditions are met. However, when used in conjunction with createBrowserRouter, these hooks can become uncooperative, leading to unexpected behavior.

The Root of the Issue

The problem lies in the way createBrowserRouter initializes the router’s history. By default, it uses the HashHistory implementation, which can interfere with the useNavigate and useBlocker hooks.

To resolve this issue, we need to switch to the BrowserHistory implementation. This will allow our router to work seamlessly with the useNavigate and useBlocker hooks.

The Solution

Now that we’ve identified the root cause of the problem, let’s implement the solution.

Step 1: Import the necessary components

import {
  createBrowserRouter,
  useNavigate,
  useBlocker,
  createHistory
} from 'react-router-dom';

Step 2: Create a Browser History instance

const history = createHistory({
  window
});

Note that we’re passing the window object as an option to the createHistory function. This is essential for the BrowsersHistory implementation to work correctly.

Step 3: Create the router instance with Browser History

const router = createBrowserRouter([
  {
    path: '/',
    element: <Home />
  }
], {
  history
});

Here, we’re creating the router instance with the createBrowserRouter function, passing in our route configuration and the history instance we created in Step 2.

Step 4: Use useNavigate and useBlocker as usual

function Home() {
  const navigate = useNavigate();
  const blocker = useBlocker();

  const handleClick = () => {
    navigate('/about');
  };

  const handleBlock = () => {
    blocker('Blocking navigation!');
  };

  return (
    <div>
      <p>Home page</p>
      <button onClick={handleClick}>Navigate to About</button>
      <button onClick={handleBlock}>Block navigation</button>
    </div>
  );
}

Now that we’ve set up our router with the BrowsersHistory implementation, we can use the useNavigate and useBlocker hooks without any issues.

Troubleshooting Tips

In case you’re still experiencing issues, here are some troubleshooting tips to help you resolve the problem:

• Make sure you’re using the latest version of React Router.
• Verify that you’ve correctly imported and created the BrowsersHistory instance.
• Check if you’re using any other history implementations or custom history functions that might be conflicting with the BrowsersHistory implementation.
• Ensure that your route configuration is correctly set up and that the useNavigate and useBlocker hooks are being used within a valid route context.
