How To Detect Esc Key Press In React And How To Handle It

Have you ever wanted to add some cool functionality to your React application that involves detecting when a user presses the Escape key? Well, you're in luck because in this article, we'll walk you through how to detect the Esc key press in React and how to handle it like a pro.

Detecting the Escape key press in React is a common requirement in many web applications, especially if you want to enhance the user experience by providing shortcuts or adding additional features. Let's dive into the steps to achieve this in your React project.

To start, you will need to create a new React component where you want to implement the Esc key press detection. Inside this component, you can set up an event listener that listens for keydown events, specifically targeting the Escape key.

Jsx

import React, { useEffect } from 'react';

const MyComponent = () =&gt; {
  useEffect(() =&gt; {
    const handleKeyPress = (event) =&gt; {
      if (event.key === 'Escape') {
        // Handle the Esc key press here
        console.log('Escape key pressed!');
      }
    };

    document.addEventListener('keydown', handleKeyPress);

    return () =&gt; {
      document.removeEventListener('keydown', handleKeyPress);
    };
  }, []);

  return <div>This is my component</div>;
};

export default MyComponent;

In the code snippet above, we are using the useEffect hook in React to add an event listener for keydown events. When the Escape key is pressed, the handleKeyPress function is called, allowing you to define custom logic on how to handle the Esc key press.

Remember to remove the event listener when the component is unmounted to prevent memory leaks or unwanted behavior. We achieve this by returning a cleanup function in the useEffect hook.

Now that you have successfully detected the Esc key press in your React component, you can proceed to handle it according to your requirements. Here are a few examples of how you can handle the Esc key press:

1. Close a modal or popup by setting a state variable that controls its visibility.
2. Navigate back or perform a specific action in your application.
3. Reset any form inputs or undo specific actions.

Feel free to customize the handleKeyPress function based on your application's needs. You can incorporate additional logic, call other functions, or update state variables within the Esc key press handling.

In conclusion, detecting the Esc key press in React is a useful feature that can enhance user interaction and improve the overall user experience of your web application. By following the simple steps outlined in this article, you can easily implement Esc key press detection and handle it efficiently in your React components. So, go ahead and add this handy functionality to your React projects today!
