Sanity.io, a content management system focused on real-time collaboration, integrates seamlessly with Gatsby, a framework known for its dynamic development experience, to offer a powerful combination for building websites. Together, they provide a real-time preview capability through Gatsby Preview, allowing teams to work collaboratively without the need for page reloads or rebuilds. Sanity's new Gatsby Source Plugin, released in January 2019, utilizes Sanity's APIs to offer instant content updates, facilitating a smooth development process with minimal configuration requirements. This integration supports robust features like the ability to overlay drafts, compatibility with the gatsby-image plugin, and comprehensive GraphQL API access, while ensuring no missing fields or types. The collaboration also capitalizes on Sanity's Portable Text for rich text content and offers a fast image pipeline with global CDN support. The combination of Sanity.io and Gatsby exemplifies an ideal JAMstack solution, providing a streamlined, fast, and efficient approach to content management and website development, with easy deployment options on platforms like Vercel or Netlify.
