Ryan Wiemer discusses his experience using Gatsby, Contentful, and Netlify to relaunch his wife's photography portfolio, highlighting the advantages of the JAMstack architecture, which combines JavaScript, APIs, and Markup for static site generation. He explains his initial hesitation with static site generators due to their complexity for non-technical users but found Gatsby appealing due to its React-based structure and rich plugin system. Wiemer successfully integrated Contentful, a headless CMS, with Gatsby using the gatsby-source-contentful plugin, enabling a flexible content model and efficient data querying via GraphQL. Hosting the site on Netlify offered ease of use, free developer tiers, and seamless integration with Contentful for site updates through webhooks. The final product was a fast, modern website with improved performance over the previous WordPress version, highlighting the maturity and potential of JAMstack for client work.
