gatsby-plugin-react-helmet

What is gatsby-plugin-react-helmet?

The gatsby-plugin-react-helmet package is a Gatsby plugin that integrates React Helmet into your Gatsby site. React Helmet is a library that allows you to manage changes to the document head, such as the title, meta tags, and other elements, from within your React components.

What are gatsby-plugin-react-helmet's main functionalities?

Setting the Page Title

This feature allows you to set the title of the page dynamically from within a React component. The title tag is updated in the document head when the component is rendered.

import React from 'react';
import { Helmet } from 'react-helmet';

const MyComponent = () => (
  <div>
    <Helmet>
      <title>My Page Title</title>
    </Helmet>
    <h1>Hello, world!</h1>
  </div>
);

export default MyComponent;

Adding Meta Tags

This feature allows you to add meta tags to the document head. You can specify various meta tags such as charset, description, keywords, etc., directly within your React components.

import React from 'react';
import { Helmet } from 'react-helmet';

const MyComponent = () => (
  <div>
    <Helmet>
      <meta charSet="utf-8" />
      <meta name="description" content="This is a description of my page" />
    </Helmet>
    <h1>Hello, world!</h1>
  </div>
);

export default MyComponent;

Link Tags

This feature allows you to add link tags to the document head. This is useful for things like setting the canonical URL of the page, adding stylesheets, or preloading resources.

import React from 'react';
import { Helmet } from 'react-helmet';

const MyComponent = () => (
  <div>
    <Helmet>
      <link rel="canonical" href="https://www.example.com/my-page" />
    </Helmet>
    <h1>Hello, world!</h1>
  </div>
);

export default MyComponent;
