Ink: React for Command-Line Interfaces

Ink is a JavaScript library that brings the declarative, component-based UI development experience of React to command-line applications. It allows developers to build complex, interactive terminal UIs using React components, leveraging features like state management, hooks, and a virtual DOM. Ink utilizes Yoga for Flexbox layout in the terminal, enabling most CSS-like layout properties. The current stable version is 7.0.1, with an active release cadence that often aligns with major React and Node.js LTS updates. Key differentiators include full React feature support within a CLI context, robust layout capabilities, and a thriving ecosystem of libraries and applications built on Ink, making it a powerful choice for modern CLI development.
