Netlify is now offering Gatsby Functions, a serverless functions feature, as part of its Essential Gatsby plugin. This allows developers to quickly set up a serverless API for their Gatsby sites. The new plugin provides support for incremental builds and image caching, making it easier to build fast and scalable websites. To get started, install the plugin in your Gatsby site as a dev dependency, add it to your netlify.toml file, and commit the changes. Then, push to your repository, and Netlify will rebuild your site with full Gatsby Functions support. The Essential Gatsby plugin is officially supported by Netlify and makes Gatsby work on Netlify "out of the box." Developers can try out the new plugin and send feedback to help improve its functionality.
