Installation

Usage

import {
  cursorUp,
  cursorDown,
  cursorTo,
  cursorLeft,
  cursorHide,
  cursorShow,
  eraseLines,
} from '@inquirer/ansi';

// Move cursor up 3 lines
process.stdout.write(cursorUp(3));

// Move cursor to specific position (x: 10, y: 5)
process.stdout.write(cursorTo(10, 5));

// Hide/show cursor
process.stdout.write(cursorHide);
process.stdout.write(cursorShow);

// Clear 5 lines
process.stdout.write(eraseLines(5));

Or when used inside an inquirer prompt:

import { cursorHide } from '@inquirer/ansi';
import { createPrompt } from '@inquirer/core';

export default createPrompt((config, done: (value: void) => void) => {
  return `Choose an option${cursorHide}`;
});
