React Helmet

React Helmet is a library that provides an easy way to manage the metadata of a React app. With React Helmet, you can dynamically update the document’s head section with different tags, such as title, meta, script, and link. This library is very useful when it comes to optimizing your React application for search engine optimization (SEO) or social media sharing.

Why use a React Helmet?

Google looks at various tags in the head section of your HTML document to understand what your page is.

For example, the title tag tells search engines the title of the page, the meta description tag provides a brief summary of the page.

React Helmet makes it easy to manage these tags in a React application. You can easily set the title, meta tags, and other head tags dynamically based on the content of the page or the user’s actions.

How to use React Helmet

First, you need to install React Helmet as a dependency in your project using NPM or Yarn:

npm install react-helmet

Once you have installed React Helmet, you can start using it in your React application. Here’s an example:

class App extends React.Component {
render() {
return (
<div>
<Helmet>
<title>My Page Title</title>
<meta name="description" content="This is my page description" />
</Helmet>
<h1>Hello, World!</h1>
<p>Welcome to my website.</p>
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("app"));

Output

In the example above, we imported the Helmet component from React Helmet and wrapped it around the content of our component. Inside the Helmet component, we can set the title and meta tags using the title and meta components respectively.

React Helmet also provides a link component to add link tags in the head section of the document. Here’s an example:

<Helmet>
<link rel="canonical" href="https://example.com/my-page" />
</Helmet>

In the example above, we added a canonical link to the head section of the document, which is useful for SEO purposes.

React Helmet also allows you to set the htmlAttributes, bodyAttributes, and base tags in the head section of the document. Here’s an example:

<Helmet
htmlAttributes={{ lang: 'en' }}
bodyAttributes={{ class: 'my-page' }}
base={{ target: '_blank', href: 'https://example.com/' }}
>
<title>My Page Title</title>
<meta name="description" content="This is a description of my page" />
<link rel="canonical" href="https://example.com/my-page" />
</Helmet>

Output

In the example above, we set the lang attribute of the html tag, the class attribute of the body tag, and the target and href attributes of the base tag.
