Sourcemap support for gulpjs.

Last verified Sep 9, 2026 against gulp-sourcemaps@3.0.0.

gulp-sourcemaps ships CommonJS only. require("gulp-sourcemaps") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 6. import "gulp-sourcemaps" 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-sourcemaps") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 6.
2. From ES modules use the default import: import gulpSourcemaps from "gulp-sourcemaps"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/gulp-sourcemaps
