Variable: ScrollView

const ScrollView: ForwardRefExoticComponent<ScrollViewProps & RefAttributes<ScrollViewRef>>

A ScrollView component for Ink applications.

Remarks

Allows scrolling through content that exceeds the visible area of the terminal. It manages a virtual viewport and renders all children, but strictly controls their visibility using overflow="hidden" and marginTop offsets.

Features:

• ↕️ Vertical scrolling
• 📏 Auto-measurement of child heights
• 🎯 Imperative scrolling methods via ref
• 🔁 Dynamic content support (adding/removing children)
• 🖥️ Viewport resize handling (via manual remeasure)

Important Notes:

• This component does NOT automatically capture keyboard input. You must use useInput in a parent component and control the scroll via the onInput hook or similar.
• Children MUST generally have specific keys if you plan to dynamically update them, to ensure correct height tracking across renders.

Example

import React, { useRef } from "react";
import { Box, Text, useInput } from "ink";
import { ScrollView, ScrollViewRef } from "ink-scroll-view";

const Demo = () => {
  const scrollRef = useRef<ScrollViewRef>(null);

  useInput((input, key) => {
    if (key.downArrow) {
      scrollRef.current?.scrollBy(1);
    }
    if (key.upArrow) {
      scrollRef.current?.scrollBy(-1);
    }
  });

  return (
    <Box height={10} borderStyle="single">
      <ScrollView ref={scrollRef}>
        {items.map((item) => (
          <Text key={item.id}>{item.label}</Text>
        ))}
      </ScrollView>
    </Box>
  );
};
