streamdown-rn@0.2.1

Patch Changes

• 3c24a0c: Fix FlashList v2 cell recycling bug where messages rendered with wrong content after scrolling

  • Fixed useRef state persisting across recycled cells by detecting content changes and resetting registry
  • Added AutoSizedImage component that fetches actual image dimensions for correct aspect ratios
  • Fixed TypeScript error where node.alt could be null

streamdown-rn@0.2.0

Minor Changes

• 17a251a: ### Breaking Changes

  • Component syntax changed: [{c:"Name",p:{...}}] replaces the old {{component:"Name",props:{...}}} syntax
  • Layout components removed: Canvas, Grid, Stack, Card are no longer exported (planned for future galerie-rn package)
  • Simplified public API: Only exports StreamdownRN, Skeleton primitives, and types

  New Features

  • Progressive prop streaming: Components render field-by-field as data streams, with skeleton placeholders for missing props
  • Format-as-you-type UX: Bold, italic, code formatting appears immediately while typing
  • Block-level memoization: Stable blocks are parsed once and never re-render
  • Full GFM support: Tables, strikethrough, task lists, autolinks via remark-gfm

  Security

  • URL sanitization: All URLs in links, images, and component props are validated against an allowlist (http:, https:, mailto:, tel:, sms:, relative URLs)
  • XSS protection: Blocks javascript:, data:, vbscript:, file: and other dangerous protocols
  • Recursive prop sanitization: Component props are sanitized at all nesting levels
  • HTML rendered as text: Raw HTML in markdown is displayed as escaped text, never executed
  • Exported utilities: sanitizeURL() and sanitizeProps() available for custom use

  Improvements

  • Compact component syntax: [{c:...,p:...}] reduces token count by ~50%
  • Robust JSON parsing: Auto-repairs incomplete JSON during streaming
  • Better streaming edge cases: Handles incomplete markdown gracefully
  • Character-level parsing: Consistent block boundary detection regardless of chunk size
