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
