TypeDoc is a documentation generator and AST analyzer that transforms TypeScript source code and comments into structured API reference websites or data files. It functions as a static site generator that converts code symbols into a searchable web interface.
The project is an extensible framework, allowing users to modify the documentation process and generator logic through a programmable plugin system and custom themes.
Its capabilities include API reference generation, source code parsing, and documentation coverage validation to ensure exported members are properly described. It supports monorepo workspaces, multi-format exports, and the integration of markdown content. The toolset also provides symbol filtering, member visibility controls, and a watch-mode for automated documentation updates as source files change.
