ESM-only ESM-only since 13.0.0 — last CommonJS version is 12.2.13

@angular/cdk dropped its CommonJS build in 13.0.0 (November 2021). The last version with a plain require()-able CommonJS entry is 12.2.13, published Nov 11, 2021.

On Node.js 20.19+, 22.12+ and newer, require("@angular/cdk") 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("@angular/cdk") fails with ERR_REQUIRE_ESM.

What to do

  1. On Node.js 20.19+, 22.12+ and newer, require("@angular/cdk") 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 cdk = await import("@angular/cdk"). That works on every Node.js version the package supports.
  3. If you need a synchronous require() or run Node.js 18: npm install @angular/cdk@12.2.13, the last CommonJS release (published Nov 11, 2021).
  4. TypeScript: types are bundled; install nothing extra.

How to import @angular/cdk

ES modules (import)

import * as cdk from "@angular/cdk";

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 cdk = require("@angular/cdk");

// Any Node.js version the package supports, from an async function:
async function main() {
  const cdk = await import("@angular/cdk");
}

// Or pin the last CommonJS release:
// npm install @angular/cdk@12.2.13

Module format by version
