What are the best practices for lazy loading in Gatsby?

Lazy loading in Gatsby helps improve performance by loading images and components only when they are needed. Best practices include using the gatsby-image plugin for images, implementing React's React.lazy for components, and ensuring proper loading states.

Can you explain how to use the gatsby-image plugin?

Sure! The gatsby-image plugin optimizes images by serving them in different sizes and formats. You can use it by installing the plugin, then using the StaticImage or GatsbyImage components in your code to load images efficiently.

What about lazy loading for third-party scripts?

For third-party scripts, you can use the loadable-components library or the native async and defer attributes in your script tags to load them only when necessary, which helps reduce initial load time.

Are there any tools to test lazy loading performance?

Yes, tools like Google Lighthouse and WebPageTest can help you analyze your site's performance, including lazy loading effectiveness.
