Release Notes

vadimdemedes/ink (ink)

v8.0.0

Compare Source

Breaking

• Require React 19.3+ 7829102
• minWidth and maxWidth on <Box> now only accept numbers (#​1029) 7cd7fd9
  • Percentage strings were never documented as supported, and Yoga resolved them against the wrong ancestor
• stdin, stdout, and stderr are now typed as generic Node.js streams (#​981) eb82d8f
  • This applies to the render() options and to useStdin(), useStdout(), and useStderr(). TTY-only properties like stdout.columns are no longer part of the types
• useInput no longer receives unrecognized terminal control sequences (#​1014) c76893e
  • Mouse reports, focus in/out events, cursor position reports, and other terminal replies used to arrive in input with the ESC stripped, as if typed. They are now dropped

New

• Add contentOffsetX and contentOffsetY props to <Box> for building scrollable views (#​765) 3ba5828
  • Combine with overflow="hidden". See the scroll example
• Add clientWidth and clientHeight to useBoxMetrics() and measureElement() (#​988) 3ba5828
  • The element size excluding borders, which is the space its content can occupy
• Accept any Node.js stream for the stdin, stdout, and stderr options of render() (#​981) eb82d8f
  • For example, PassThrough or other Readable/Writable streams. Raw mode is used only when stdin is a TTY with setRawMode()
• Skip unchanged line prefixes in incrementalRendering mode (#​1036) 91eb50a
  • Only the changed part of a line is written, which reduces output and flicker
• Drop the ws dependency in favor of the native WebSocket for React DevTools (#​976) 33567ed
• Recognize application keypad Enter as key.return b73ebf4

Migration guide

React 19.3

Upgrade react (and @types/react) to 19.3 or later.

minWidth and maxWidth

Use a number. If you need a relative minimum or maximum width, compute it from useWindowSize() or useBoxMetrics() of the parent.

-<Box minWidth="50%">
+<Box minWidth={Math.floor(columns / 2)}>

Stream types

useStdout().stdout is now typed as NodeJS.WritableStream, so TTY properties like columns and rows are no longer available in the types. Use useWindowSize() instead, which also re-renders on resize.

-const {stdout} = useStdout();
-const width = stdout.columns;
+const {columns: width} = useWindowSize();

Control sequences in useInput

If your useInput handler parsed mouse reports, focus events, or other terminal replies from input, it will no longer receive them. Keys that Ink recognizes, including Kitty keyboard protocol events, are not affected.

The red Typecheck is real: ink 8 narrows the type of useStdout().stdout. It changed from NodeJS.WriteStream to NodeJS.WritableStream, so ink/library/useTerminalSize.ts no longer typechecks. That file reads rows, columns and isTTY, which gives 5 TS2339 errors at lines 7, 8, 12, 18 and 19.

Ink 8 now ships a useWindowSize() hook that returns { columns, rows } and re-renders on resize, which is exactly what our hook does by hand. I verified this replacement on the branch:

import { useWindowSize } from 'ink';

export function useTerminalSize() {
	return useWindowSize();
}

With that change at 63cb41fb (Node 24.21), typecheck, build, lint and dprint all exit 0. Vitest passes 53 files / 345 tests, and that includes ink/main.test.tsx with COLUMNS=200. The four callers (VirtualList, ActionsView, ChatContent, DiffApprovalView) keep the same return shape.

One more thing to know: ink-stepper@0.2.3, the latest release, still peers ink ^6.6.0 || ^7.0.0. Renovate also bumped our overrides.ink-stepper.ink to ^8.0.0, so the stepper is being forced onto an ink major it doesn't declare support for. Tests pass, but ink-stepper has regressed before on small bumps, so please click through the setup walkthrough once before merging.

[dawsontoth]

Approving with the ink 8 fix (1f9f320): useTerminalSize now uses ink's useWindowSize(). Typecheck, Build, Lint, Format and Test are all green. Before merging, click through the setup walkthrough once: ink-stepper 0.2.3 still peers ink ≤7 and is only forced onto 8 by overrides.
