Slidev is a developer-oriented slide presentation tool that turns Markdown files into interactive, web-based slide decks. The system is built as a monorepo with several packages: a Node.js CLI and Vite-based dev server (`packages/slidev`), a Vue 3 client application (`packages/client`), a markdown parser (`packages/parser`), shared type definitions (`packages/types`), a VS Code extension (`packages/vscode`), and scaffolding tools (`create-app`, `create-theme`). The core workflow involves parsing Markdown slides with frontmatter, rendering them as Vue components with support for code highlighting (Shiki), diagrams (Mermaid, PlantUML, KaTeX), interactive editors (Monaco), animations (v-click, v-mark), and drawing tools. Export capabilities include PDF, PPTX (both raster and editable), PNG, and Markdown via Playwright. The system also includes a Model Context Protocol (MCP) server for AI agent integration, enabling programmatic slide editing. The architecture is modular: the parser handles slide splitting and feature detection, the client provides a rich presentation UI with presenter mode, and the CLI orchestrates build, serve, and export commands. The VS Code extension adds language support, a preview panel, and AI tools. Overall, Slidev is a mature, feature-rich application for creating technical presentations with minimal friction.
