# Is cypress ESM-only? Can you require() it?

> cypress@16.0.0 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

Cypress is a next generation front end testing tool built for the modern web

Latest version 16.0.0, published Sep 1, 2026.

cypress publishes both a CommonJS entry and a native ESM entry (ESM added in 10.0.0). require("cypress") should work on every Node.js version the package supports (^22.0.0 || ^24.0.0 || >=26.0.0); the runtime probe has not run for this version. import "cypress" works alongside it.

## What to do

1. Nothing to change. require("cypress") should work on every Node.js version the package supports (^22.0.0 || ^24.0.0 || >=26.0.0); the runtime probe has not run for this version. import * as cypress from "cypress" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
