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

Runtime typescript and ESM support for Node.js

Last verified Sep 9, 2026 against jiti@2.7.0. Markdown · JSON

Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

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.

CommonJS (require)

const jiti = require("jiti");

Module format by version
