React Helmet: Mastering Your React Site's Head
The section of your website, while often overlooked, is crucial for SEO, social media integration, and loading essential assets like stylesheets and analytics libraries. Managing this dynamically in a React application can be challenging. This tutorial demonstrates how to efficiently handle the
content using React Helmet, leveraging server-side rendering (SSR) with Gatsby.
Directly manipulating document.title
and meta tags within componentDidMount
is cumbersome and error-prone. React Helmet provides a streamlined solution. However, to fully harness its power, especially for SEO (search engines struggle with client-side rendered content), SSR is essential. Therefore, we'll use Gatsby, a React-based static site generator that offers built-in SSR.
Setting Up Gatsby and React Helmet
-
Install Gatsby CLI:
1
npm i -g gatsby-cli
Copy after login -
Create a New Gatsby Project:
1
gatsby
new
my-gatsby-site https:
//github.com/gatsbyjs/gatsby-starter-hello-world
Copy after login -
Install React Helmet and Gatsby Plugin:
1
npm i --save react-helmet gatsby-plugin-react-helmet
Copy after login -
Configure Gatsby: Add the plugin to
gatsby-config.js
:1
2
3
module.exports = {
plugins: [`gatsby-plugin-react-helmet`],
};
Copy after login
Building a Dynamic Layout Component
Create a components/layout.js
file:

{children}Create src/css/main.css
:

Creating Pages
Update src/pages/index.js
:
1 2 3 4 5 6 7 8 |
|
Create src/pages/cars.js
:

|
Building and Serving
Run gatsby build
and then gatsby serve
to see the results with SSR. Inspect the source code to verify that React Helmet's content is correctly rendered. The lang
attribute and custom CSS class will be applied as expected. Remember to replace the placeholder structured data with your actual data. This approach ensures your React application's metadata is properly indexed by search engines and social media crawlers.
