# `react-doctor/ink-use-suspend-terminal`

Interactive child process bypasses Ink suspension

- **Category:** Bugs
- **Severity:** error
- **Source:** oxlint-plugin-react-doctor
- **Framework:** global
- **Enabled when:** Ink >= 7.1.0

## Validate the diagnostic

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

Confirm the reported code matches `react-doctor/ink-use-suspend-terminal`. 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

```tsx
import { useInput } from "ink";
import { spawn } from "node:child_process";

const App = () => {
  useInput(() => {
    spawn("vim", [], { stdio: "inherit" });
  });
  return null;
};
```

### Corrected pattern

```tsx
import { useApp, useInput } from "ink";
import { spawn } from "node:child_process";

const App = () => {
  const { suspendTerminal } = useApp();
  useInput(() => {
    suspendTerminal(() => {
      spawn("vim", [], { stdio: "inherit" });
    });
  });
  return null;
};
```

## 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.

````text
Fix every confirmed `react-doctor/ink-use-suspend-terminal` diagnostic in the current repository.

Required change:
- Run inherited-TTY child processes inside `useApp().suspendTerminal()`.

Reference transformation:

Before:
```tsx
import { useInput } from "ink";
import { spawn } from "node:child_process";

const App = () => {
  useInput(() => {
    spawn("vim", [], { stdio: "inherit" });
  });
  return null;
};
```

After:
```tsx
import { useApp, useInput } from "ink";
import { spawn } from "node:child_process";

const App = () => {
  const { suspendTerminal } = useApp();
  useInput(() => {
    suspendTerminal(() => {
      spawn("vim", [], { stdio: "inherit" });
    });
  });
  return null;
};
```

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 >= 7.1.0`.

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.
