Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/ink-ctrl-c-handler-requires-exit-option. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

import { render, useInput } from "ink";

const App = () => {
  useInput((input, key) => {
    if (key.ctrl && input === "c") work();
  });
  return null;
};

render(<App />);

Corrected pattern

import { render, useInput } from "ink";

const App = () => {
  useInput((input, key) => {
    if (key.ctrl && input === "c") work();
  });
  return null;
};

render(<App />, { exitOnCtrlC: false });

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/ink-ctrl-c-handler-requires-exit-option diagnostic in the current repository. Required change: - Pass {exitOnCtrlC: false} to render() before handling Ctrl-C with useInput.

Reference transformation:Before:

import { render, useInput } from "ink";

const App = () => {
  useInput((input, key) => {
    if (key.ctrl && input === "c") work();
  });
  return null;
};

render(<App />);

After:

import { render, useInput } from "ink";

const App = () => {
  useInput((input, key) => {
    if (key.ctrl && input === "c") work();
  });
  return null;
};

render(<App />, { exitOnCtrlC: false });

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. - Confirm this rule is enabled for the project: Ink >= 3.0.0. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
