Nahuel Scotti describes his experience transitioning his blog from Jekyll, a Ruby-based static site generator, to Gatsby, a React-powered framework, primarily due to a preference for Node.js and the benefits of faster development workflows. He initially appreciated Jekyll for its Markdown support but found maintaining Ruby dependencies cumbersome, especially as his primary development work shifted to Node.js. Gatsby's compatibility with Markdown and YAML front matter eased the migration process, and the use of Tachyons helped replicate his blog's existing theme with minimal CSS. Challenges included preserving URL slugs and dates, which he addressed using Gatsby's onCreateNode API. Scotti highlights the advantage of Gatsby's integration with React and GraphQL, allowing for dynamic data querying and transformation. He also explores deployment options, moving from GitLab Pages to Netlify for improved reliability. The migration represents a significant shift in his development approach, enhancing his ability to contribute to the Node ecosystem while maintaining the blog's content and appearance.
