Blessed is a "curses-like library with a high level terminal interface API for Node.js."

  • Base Nodes: Node, Screen, Element
  • Boxes: Box, Text, Line, BigText
  • Lists: List, FileManager, ListTable, Listbar
  • Forms: Form, Input, Textarea, Textbox, Button, Checkbox, RadioSet, RadioButton
  • Prompts: Prompt, Question, Message, Loading
  • Data Display: ProgressBar, Log, Table
  • Special Elements: Terminal, Image, ANSIImage, OverlayImage, Video, Layout

This project is available on GitHub and npm.
