In this blog post by Joaquín Bravo Contreras, the author outlines a detailed process for migrating a simple blog with features like images, comments, and tags from Drupal to Gatsby. The transition to a static site generator like Gatsby is presented as a cost-effective solution, eliminating the need for shared hosting and offering free hosting via GitHub Pages while providing an opportunity to learn React. The process involves exporting the Drupal database to a local SQLite file using the mysql2sqlite project, and then creating scripts to extract essential data such as post titles, creation dates, and tags. The author also covers handling URL aliases, image URLs, and converting post content to Markdown. For comments, a separate script is used to export them to an XML format compatible with Disqus, facilitating their integration into the new site. The post provides a comprehensive guide for anyone looking to undertake a similar migration, complete with script examples and a working example available on GitHub.
