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

> jiti@2.7.0 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

Runtime typescript and ESM support for Node.js

Last verified Sep 9, 2026 against jiti@2.7.0.

jiti publishes both a CommonJS entry and a native ESM entry (ESM added in 2.0.0). require("jiti") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "jiti" works alongside it.

## What to do

1. Nothing to change. require("jiti") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import * as jiti from "jiti" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
