To add a canonical tag to a single-page application in React.js, you can use the react-helmet library which allows you to manipulate the head of your application.

Here are the steps to add a canonical tag to your single-page application:

1. Install react-helmet by running the following command in your terminal:npm install react-helmet
2. Import Helmet from react-helmet in your component:import { Helmet } from 'react-helmet';
3. In your component's render method, wrap the content that you want to include the canonical tag for with the Helmet component:<Helmet> <link rel="canonical" href="https://example.com/page" /> </Helmet> Note: Replace https://example.com/page with the actual URL of the page.
4. Save your changes and the canonical tag will now be added to your single-page application.

By adding the canonical tag to your single-page application, you are indicating to search engines which version of your content is the preferred one in case of duplicate content issues.
