Shiki is a syntax highlighting engine that generates color-coded HTML or ANSI output from source code. It functions as a static code highlighter, utilizing standard grammar definitions to parse text and apply accurate visual styling for documentation and terminal displays.
The engine distinguishes itself by using a TextMate grammar parser to interpret text patterns, ensuring that code displays match the visual appearance of professional editors. It operates through an isomorphic runtime that supports both browser and server environments, utilizing WebAssembly for consistent execution and pre-compiled grammar serialization to manage performance and memory overhead.
The library supports a range of integration methods, including server-side rendering and static site generation, to facilitate the creation of readable code examples in technical documentation and web content. It maps semantic tokens to specific color values through theme injection during the final rendering phase.
