Uselocation() may be used only in the context of a component.

The error message “uselocation() may be used only in the context of a <router> component.” occurs when trying to use the uselocation() hook outside of a router component.

In order to use the uselocation() hook, you need to wrap your component with the <Router> component provided by a routing library such as React Router.

Here is an example demonstrating how to use uselocation() within a router component:

// Import necessary dependencies
import React from 'react';
import { Router, Route, Switch, useLocation } from 'react-router-dom';

// Define your component
const MyComponent = () => {
  // Use the useLocation() hook
  const location = useLocation();
  
  // Render your component with the location data
  return (
    

      Current location: {location.pathname}
    
  );
};

// Wrap your component inside Router
const App = () => {
  return (
    
      
        
      
    
  );
};

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

In the above example, we import the necessary dependencies including Router, Route, Switch, and useLocation from the React Router package. We define our component MyComponent which uses the uselocation() hook to access the current location. We wrap our component inside the <Router> component and define routes using the Route and Switch components. Finally, we render our App component to the HTML element with the ID of ‘root’.

By following this pattern, the uselocation() hook will work correctly as it is used within the context of a router component.
