tmpDir to tmpdir

Migrate deprecated os.tmpDir() to os.tmpdir() for Node.js DEP0022

This recipe transforms tmpDir function calls to tmpdir to handle Node.js DEP0022.

What It Does

This codemod updates:

• Function calls from tmpDir() to tmpdir()
• Import/require statements to use the correct function name

Before/After

ESM

Before:

import { tmpDir } from 'node:os';
const foo = tmpDir();

After:

import { tmpdir } from 'node:os';
const foo = tmpdir();

CommonJS

Before:

const { tmpDir } = require('node:os');
const foo = tmpDir();

After:

const { tmpdir } = require('node:os');
const foo = tmpdir();

Usage

Run this codemod on your project:

npx codemod node/userland/tmpdir-to-tmpdir

This is a simple naming change where tmpDir() (with capital ‘D’) was deprecated in favor of the lowercase tmpdir() to maintain consistency with Node.js naming conventions.
