Spectacle is a React-based presentation framework that enables developers to author slide decks using JSX and MDX syntax. It provides a component-driven approach to building presentations, where slides are composed as React components with declarative layouts, theme-driven styling, and step-based animation sequencing.
The framework distinguishes itself through its support for live coding demonstrations within slides, allowing presenters to execute and display code directly during a talk. It includes a presenter mode with dual-view architecture that shows speaker notes, a timer, and upcoming slides on a separate screen while the audience sees the main presentation. Keyboard-driven navigation, a command palette overlay, and fullscreen mode toggle provide comprehensive control over slide flow, while a printer-friendly PDF export option allows for distribution of the deck.
Spectacle offers a range of predefined slide layouts including centered content, columns, code blocks, images, tables, and quotes, all styled through a theme-driven system that maps semantic tokens to colors, typography, and spacing. The framework processes MDX files through a webpack loader, enabling authors to combine Markdown content with React components, and includes a development server with project scaffolding for quick setup.
