How do you set the document title in React?

When building a React application, you may come across situations where you need to dynamically set the document title based on the current state or data. In this blog post, we will explore two common approaches to achieve this.

1. Using the document.title property

The simplest way to set the document title in React is by directly modifying the document.title property. This approach works well for small applications or components where you only need to set the title in a single place.

Here’s an example of how you can set the document title using this approach:

import React, { useEffect } from 'react';

const MyComponent = () => {
  useEffect(() => {
    document.title = 'My Document Title';
  }, []);

  return (
    

      
Hello, World!
      This is my component.
    
  );
};

export default MyComponent;

In the above example, we use the useEffect hook to set the document title when the component mounts. The empty dependency array [] ensures that the effect runs only once.

2. Using a custom hook

If you need to set the document title in multiple components or want more flexibility, you can create a custom hook to handle this functionality. This approach allows you to encapsulate the logic and reuse it across your application.

Here’s an example of how you can create a custom hook to set the document title:

import { useEffect } from 'react';

const useDocumentTitle = (title) => {
  useEffect(() => {
    document.title = title;
  }, [title]);
};

export default useDocumentTitle;

To use this custom hook, you can simply import it into your component and call it with the desired title:

import React from 'react';
import useDocumentTitle from './useDocumentTitle';

const MyComponent = () => {
  useDocumentTitle('My Document Title');

  return (
    

      
Hello, World!
      This is my component.
    
  );
};

export default MyComponent;

By using the custom hook, you can easily set the document title in multiple components by calling useDocumentTitle with different titles.

These are two common approaches to set the document title in React. Choose the one that best suits your needs and the complexity of your application.

Remember, setting the document title dynamically can enhance the user experience and provide relevant information to your users.
