ESM-only ESM-only since 3.0.0 — last CommonJS version is 2.1.0

is-binary-path dropped its CommonJS build in 3.0.0 (April 2024). The last version with a plain require()-able CommonJS entry is 2.1.0, published Apr 19, 2019; it declares support for Node.js >=8.

On Node.js 20.19+, 22.12+ and newer, require("is-binary-path") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("is-binary-path") fails with ERR_REQUIRE_ESM.

What to do

  1. On Node.js 20.19+, 22.12+ and newer, require("is-binary-path") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
  2. From a CommonJS file, use a dynamic import inside an async function: const isBinaryPath = await import("is-binary-path"). That works on every Node.js version the package supports (>=18.20).
  3. If you need a synchronous require() or run Node.js 18: npm install is-binary-path@2.1.0, the last CommonJS release (published Apr 19, 2019); it declares Node.js >=8.
  4. TypeScript: types are bundled; install nothing extra.

import * as isBinaryPath from "is-binary-path";

Namespace import shown because the ESM entry may have no default export; use named imports for what it exports.

CommonJS (require)

// Node.js 20.19+, 22.12+ and newer (verified):
const isBinaryPath = require("is-binary-path");

// Any Node.js version the package supports (>=18.20), from an async function:
async function main() {
  const isBinaryPath = await import("is-binary-path");
}

// Or pin the last CommonJS release (declares Node.js >=8):
// npm install is-binary-path@2.1.0
