The component integrates three major specialized features through a modular plug-in architecture: a KaTeX-based mathematical formula engine that supports AMS-LaTeX 95% mathematical notation; integration with Mermaid 10.3+ for automated rendering of 28 chart types; and Shiki's code highlighting system that provides support for 200+ languages and 150 themes. These features are coordinated through a unified stream processing pipeline, ensuring that even complex content can be rendered in real-time.
Performance tests show that Streamdown maintains a smooth 60fps while simultaneously rendering a mix of mathematical formulas, timing diagrams, and Python code with a memory footprint 40% less than traditional solutions. its plug-in system allows developers to flexibly extend it, and companies have already successfully integrated PlantUML and Graphviz support.
