How to set the document title in React
In a webpage, the <title> element is used to specify the title of a document. The text that is specified within the <title> tags is displayed in the title bar of the web browser and is also used as the page title in search engine results.
The <title> element should be placed within the <head> section of an HTML document and should contain a brief and descriptive title that accurately reflects the content of the page. The title is an important part of on-page SEO as it helps search engines to understand what the page is about and how it should be categorized in search results. Additionally, a well-crafted title can also help to entice users to click on your page when it appears in search results.

To set the document title in a React application, you can make use of the useEffect hook. Here’s an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 | import React, { useEffect } from 'react'; function MyComponent() { useEffect(() => { document.title = 'My Page Title'; }, []); return ( // JSX for your component goes here ); } export default MyComponent; |
In the code above, the useEffect hook is used to set the document title to “My Page Title” when the component mounts. The empty dependency array [] is passed as the second argument to useEffect, which means the effect will only run once when the component mounts.
You can replace “My Page Title” with any string you want to use as the title for your page.
There are a few other options to set the document title in React:
Using React Helmet
React Helmet is a third-party library that enables you to change the head of your React app. You can use it to set the document title, meta tags, and other head elements. First, you need to install it using npm install react-helmet. Then, import it and use the Helmet component to set the document title:
1 2 3 4 5 6 7 8 9 10 11 12 | import { Helmet } from 'react-helmet'; function MyComponent() { return ( <div> <Helmet> <title>My Document Title</title> </Helmet> {/* rest of the component */} </div> ); } |
Using a Higher-Order Component
You can create a Higher-Order Component (HOC) that sets the document title and wraps your component with it. This can be useful if you need to set the title for multiple components. Here’s an example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | function withDocumentTitle(title) { return function(Component) { return function(props) { document.title = title; return <Component {...props} />; }; }; } function MyComponent() { return ( <div> {/* rest of the component */} </div> ); } export default withDocumentTitle('My Document Title')(MyComponent); |
