OpenTUI Design Skill

Description

Comprehensive toolkit for designing and implementing CLI applications with OpenTUI and SolidJS.

When to Use

• Building new CLI screens or components with OpenTUI
• Debugging input handling issues
• Implementing screen navigation
• Handling mouse events and limitations
• Optimizing CLI performance

Critical Knowledge

Key Propagation Prevention

When navigating between screens with Enter key, the same keypress can propagate to the new screen. Always use:

1. key.preventDefault() at the source
2. Initial frame delay at the destination
3. focused prop control on interactive elements

SolidJS Reactivity

Never destructure props - always access via props.xxx to maintain reactivity.

Mouse Limitations

OpenTUI's Selection API (useSelectionHandler) does not reliably work. Set useMouse: false to allow OS-level copy, but this disables wheel scroll.
