Releases

@streamdown/code@2.0.0

Major Changes

• db6fefc: Upgrade Shiki to v4. Node.js 20 or newer is now required when using @streamdown/code.

remend@1.3.2

Patch Changes

• e0ce123: Incomplete images during streaming now render a loading placeholder instead of being removed entirely. Incomplete images (e.g. ![alt](https://exampl) are replaced with ![alt](streamdown:incomplete-image) by remend, and the streamdown ImageComponent renders an animated skeleton for this special URL. This mirrors the existing behavior for incomplete links (streamdown:incomplete-link). The streamdown protocol is allowlisted for img[src] in the default sanitize schema so the sentinel survives rehype-sanitize + rehype-harden.

streamdown@2.6.1

Patch Changes

• c971f42: Wire onCopy and onError through default code and Mermaid copy controls via controls.code.copy and controls.mermaid.copy.

• 163c63b: fix(code-block): use absolute positioning for action buttons to fix click events in nested scroll containers

  Switches the code block action button wrapper from position: sticky to
  position: absolute (with position: relative on the container) so that
  hit-testing works correctly in layouts with multiple nested overflow: auto
  scroll containers. Previously, the sticky + pointer-events-none/auto
  pattern caused browsers to mis-route click events to the code block wrapper
  rather than the buttons when the component was embedded in 2+ nested scroll
  containers.

• e0ce123: Incomplete images during streaming now render a loading placeholder instead of being removed entirely. Incomplete images (e.g. ![alt](https://exampl) are replaced with ![alt](streamdown:incomplete-image) by remend, and the streamdown ImageComponent renders an animated skeleton for this special URL. This mirrors the existing behavior for incomplete links (streamdown:incomplete-link). The streamdown protocol is allowlisted for img[src] in the default sanitize schema so the sentinel survives rehype-sanitize + rehype-harden.

• 18dcb20: Add a top-level portal prop for configuring the container used by Mermaid fullscreen, table fullscreen, and the built-in link safety modal.

• fdf4e33: Fix Mermaid diagrams so text is readable and diagrams auto-fit container.

  • Normalize SVG to remove responsive shrinking
  • Extract intrinsic size from viewBox
  • Add width-and-height auto-fit in PanZoom
  • Preserve user zoom/pan after initial fit
  • Add tests for SVG utilities and auto-fit behavior

• a155a9e: Update marked from ^17.0.1 to ^18.0.11.

  marked v18 no longer folds a block token's trailing blank line(s) into its own raw; that whitespace now surfaces as a separate space token immediately following the block (e.g. after html, heading, and table tokens). This changed the token stream shape that parseMarkdownIntoBlocks consumes, causing a dangling space token after a closed custom-tag HTML block to be emitted as its own standalone block. parseMarkdownIntoBlocks now folds a space token into the preceding block instead of pushing it as a new one, restoring v17-identical block boundaries and counts. The lossless token.raw concatenation invariant is preserved.

• Updated dependencies [e0ce123]

  • remend@1.3.2
