Code Surfer is a web-based code slide framework and presentation tool designed for creating technical slides. It functions as a code animation library and diff visualizer that enables the rendering of source code with animated transitions, zooming, and highlighting.
The project focuses on visualizing code evolution through state morphing and diff animations. It uses coordinate-based view transitions and smooth scrolls to guide viewers through changes between different code versions across a slide deck.
The framework provides capabilities for attention management via line-level focus, section zooming, and visual masking. It supports organized layouts through parallel code columns, sequential scrolling for long snippets, and the ability to import external source files to maintain a single source of truth. Visual styling is handled through custom themes and configuration-driven typography.
