ESM-only ESM-only since 3.0.0 — last CommonJS version is 2.0.1

content-disposition dropped its CommonJS build in 3.0.0 (August 2026). The last version with a plain require()-able CommonJS entry is 2.0.1, published May 28, 2026; it declares support for Node.js >=18.

On Node.js 22.12+ and newer (content-disposition@3.0.0 declares Node.js >=22), require("content-disposition") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 22, 24 and 26. Node.js 18 has no require(esm), and content-disposition@3.0.0 declares Node.js >=22, so 18 is outside its supported range anyway.

content-disposition@3.0.0 declares engines ">=22", so Node.js 18, 20 are outside its supported range regardless of module format.

What to do

  1. On Node.js 22.12+ and newer (content-disposition@3.0.0 declares Node.js >=22), require("content-disposition") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 22, 24 and 26.
  2. From a CommonJS file, use a dynamic import inside an async function: const contentDisposition = await import("content-disposition"). That works on every Node.js version the package supports (>=22).
  3. If you need a synchronous require() or run Node.js 18: npm install content-disposition@2.0.1, the last CommonJS release (published May 28, 2026); it declares Node.js >=18.
  4. content-disposition@3.0.0 declares engines ">=22", so Node.js 18, 20 are unsupported regardless: upgrade Node.js or pin an older release.
  5. TypeScript: types are bundled; install nothing extra.

How to import content-disposition

ES modules (import)

import * as contentDisposition from "content-disposition";

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

CommonJS (require)

// Node.js 22.12+ and newer (verified):
const contentDisposition = require("content-disposition");

// Any Node.js version the package supports (>=22), from an async function:
async function main() {
  const contentDisposition = await import("content-disposition");
}

// Or pin the last CommonJS release (declares Node.js >=18):
// npm install content-disposition@2.0.1

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (18 versions; the newest 18 shown).
