detect-package-manager

How does this work?

1. When there's yarn.lock, package-lock.json, pnpm-lock.yaml, or bun.lockb in current working directory, it will skip other operations and directly resolve yarn, npm, pnpm, or bun.
2. When there's no lockfile found, it checks if yarn, pnpm, or bun command exists. If so, it resolves yarn, pnpm, or bun otherwise npm.
3. Results are cached.

Install

yarn add detect-package-manager

Usage

const { detect } = require("detect-package-manager");

detect().then((pm) => {
  console.log(pm);
  //=> 'yarn', 'npm', or 'pnpm', 'bun'
});
