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

Gulp extension to add header to file(s) in the pipeline.

Last verified Sep 9, 2026 against gulp-header@2.0.12.

gulp-header ships CommonJS only. require("gulp-header") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "gulp-header" 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("gulp-header") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import gulpHeader from "gulp-header"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/gulp-header
