The ReactiveNotes plugin lets you embed interactive React components directly into your notes, transforming them into dynamic and programmable documents. It supports full React 18 features including hooks, state management, lifecycle handling, and integration with Obsidian's file system and theme. Users can persist state in frontmatter, render charts with libraries like Recharts or Lightweight Charts, manipulate canvas elements, and even import libraries from CDN. Each note can maintain its own independent state, enabling reusable component templates. This plugin is ideal for developers, data analysts, and tinkerers looking to combine note-taking with interactivity, custom tooling, or rich visualizations.
