Last verified Sep 9, 2026 against babel-preset-jest@30.5.0.

babel-preset-jest ships CommonJS only. require("babel-preset-jest") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^18.14.0 || ^20.0.0 || ^22.0.0 || >=24.0.0. import "babel-preset-jest" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("babel-preset-jest") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^18.14.0 || ^20.0.0 || ^22.0.0 || >=24.0.0.
2. From ES modules use the default import: import babelPresetJest from "babel-preset-jest"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for babel-preset-jest; declare the module yourself if you need them.
