datasette.io news preview

Tool: datasette.io news preview The datasette.io website has a news section built from this news.yaml file in the underlying GitHub repository. The YAML format looks like this: - date: 2026-04-15 body: |- Datasette 1.0a27 changes how CSRF protection works in a way that simplifies form and API integration, and introduces a new RenameTableEvent for when a table is renamed by a SQL query. - date: 2026-03-18 body: |- ... This format is a little hard to edit, so I finally had Claude build a custom preview UI to make checking for errors have slightly less friction. I built it using standard claude.ai and Claude Artifacts, taking advantage of Claude's ability to clone GitHub repos and look at their content as part of a regular chat: Clone https://github.com/simonw/datasette.io and look at the news.yaml file and how it is rendered on the homepage. Build an artifact I can paste that YAML into which previews what it will look like, and highlights any markdown errors or YAML errors Tags: vibe-coding, claude, tools, datasette
