Is @angular/router ESM-only? Can you require() it?

Angular - the routing library

Last verified Sep 9, 2026 against @angular/router@22.1.5. JSON

ESM-only ESM-only since 13.0.0 — last CommonJS version is 12.2.17

@angular/router dropped its CommonJS build in 13.0.0 (November 2021). The last version you can require() on every Node.js version, including 18 and older, is 12.2.17, published Nov 22, 2022.

require("@angular/router") failed in our probe on Node.js 20+ as well. See the runtime matrix below for the exact error.

@angular/router@22.1.5 declares engines "^22.22.3 || ^24.15.0 || >=26.0.0", so Node.js 18, 20 are outside its supported range regardless of module format.
