Highlights

This release introduces automatic thumbnail generation for all asset types and adds CSV (text/csv) as a new asset content type with an interactive table viewer.

Asset Thumbnails

Assets now display visual thumbnail previews in the asset grid instead of plain icons. Thumbnails are generated client-side when an asset is first viewed and uploaded to S3 for subsequent display.

  • Client-side capture pipeline: HTML and JSX assets are rendered in a sandboxed iframe and captured with html2canvas; Markdown, SVG, and CSV assets are rendered directly in the DOM and captured at 400x300px
  • Background queue: ThumbnailQueue processes assets without thumbnails in the background, one at a time, without blocking the UI
  • Regeneration on save: Editing and saving asset content automatically regenerates the thumbnail
  • Server-side storage: New PUT /assets/:id/thumbnail endpoint stores PNG thumbnails in S3; thumbnail_s3_key column added to the portal assets table (migration 000020)
  • Admin support: Admin asset detail view also displays and regenerates thumbnails

CSV Asset Support

A new text/csv content type joins HTML, JSX, SVG, and Markdown:

  • Interactive table preview: Parsed with Papa Parse with dynamic typing, sortable columns (numeric-aware), and a global search filter across all columns
  • Performance: Display capped at 500 rows with a "Showing X of Y" footer
  • Thumbnails: First 10 rows rendered as a styled HTML table and captured via the DomCapture path
  • Source editing: Raw CSV text is editable in the Source tab (plain text mode)
  • Public viewer: CSV renders the same interactive table in the public share viewer
  • UI polish: Table2 icon from lucide-react, emerald badge color, and a CSV option in the content type filter dropdown
