Build React components for Obsidian plugins by creating functional components with TypeScript typings, mounting them using React 18's createRoot API into Obsidian Views or Modals, and handling cleanup on close. Use Obsidian's ItemView and Modal classes as container patterns, configure esbuild for proper bundling, and apply Obsidian styling conventions to integrate seamlessly with the plugin UI.

Yes. React components in Obsidian plugins benefit from full TypeScript support for prop typing and state management. Define strongly typed props for your functional components, use React hooks for state and effects, and leverage TypeScript's type system to catch integration errors early when binding components to Obsidian's ItemView and Modal interfaces.

Use React 18's createRoot to mount components into a DOM element within an Obsidian View or Modal. Store the root reference, pass Obsidian context and props to your component, implement cleanup by calling root.unmount() when the View or Modal closes, and ensure esbuild is configured to bundle React correctly for plugin distribution.

React components in Obsidian should follow Obsidian styling conventions and use the plugin's CSS to maintain visual consistency. Apply Obsidian's CSS classes and design tokens in your component markup, configure your esbuild setup to process stylesheets alongside component code, and test styling in the Obsidian theme to ensure proper rendering.

Use React hooks like useState and useEffect to manage component state and lifecycle. Implement cleanup in useEffect return functions to handle unmounting properly. Structure props to pass Obsidian context (plugin instance, workspace, vault) and UI data, and update props when the parent View or Modal state changes to keep the component synchronized.

React components must work within Obsidian's DOM structure and cannot override core Obsidian behaviors. Ensure cleanup is thorough to prevent memory leaks in long-running plugins, respect Obsidian's security sandbox if applicable, and test component rendering performance since plugin UIs run in the main thread alongside Obsidian's editor and file operations.
