Ink - React for CLIs

React for CLIs. Build and test your CLI output using components.

Ink provides the same component-based UI building experience that React offers in the browser, but for command-line apps. It uses Yoga for Flexbox layouts in the terminal.

Important: All text must be wrapped in a <Text> component.

Quick Example

import {render, Text, Box} from 'ink';

render(
	<Box borderStyle="round" padding={1}>
		<Text color="green">Hello World</​Text>
	</​Box>
);

Components

  • <Text> - Display text with styling (color, bold, italic, underline, etc.)
  • <Box> - Flexbox container for layouts
  • <Newline> - Insert newline characters
  • <Spacer> - Flexible space that expands to fill available space
  • <Static> - Permanently render output above everything else (for logs, completed tasks)
  • <Transform> - Transform string representation before output
