Streamdown 2.2 - animated streaming and better custom HTML support
Streamdown 2.2 adds animated per-word text streaming, improved custom HTML handling with enhanced tag stripping, and full ReactMarkdown compatibility for drop-in migration. The release also removes CommonJS builds and includes rendering and security fixes across tables, code blocks, LaTeX, and diagrams.
Streamdown 2.2 delivers animated per-word text streaming, improved custom HTML handling, and drop-in compatibility with ReactMarkdown - making it easier to adopt Streamdown in existing projects.
By importing the Streamdown stylesheet and enabling the new animated prop, streaming content renders with smooth per-word text animation. This provides a polished experience for AI chat interfaces and other real-time text applications.
The components prop now accepts custom HTML attributes by adding elements to allowedTags. The Remend engine has also been improved to strip incomplete HTML tags during streaming, preventing visual glitches from partial markup.
Streamdown now supports the remaining ReactMarkdown props, making migration a one-line replacement. Projects using ReactMarkdown can swap to Streamdown without refactoring component configurations.
This release also removes CommonJS builds, adds bundled-language aliases for common JavaScript, TypeScript, and shell labels, and includes numerous rendering and security fixes across tables, code blocks, LaTeX, and Mermaid diagrams.
