Thank you for a quick response, but as I already wrote, this did not work. However I just manage to figure it out what was causing the bug I just mentioned. It was my writing style... I do not use semicolons, and the next line after the call to register the plugin was (function () { Not 100% sure why this happened, but now I will be forever paranoid about this type of bug Might reconsider my decision to write js without semicolons. On ES modules. I have found on Babelify's github page, that Browserify does not take node_modules into account. Tried adding that to gsap's package.json, but that did not fix the problem. In any case. UMD way seems to be working and that's good enough for me. Cheers

Hey, Whenever I try to import a plugin the build fails with this message: SyntaxError: 'import' and 'export' may appear only with 'sourceType: module' (758:0) while parsing /node_modules/gsap/ScrollTrigger.js while parsing file: /node_modules/gsap/ScrollTrigger.js at DestroyableTransform.end [as _flush] (/node_modules/insert-module-globals/index.js:114:21) If I only import 'gsap' it works perfectly. Gulpfile.js: const { watch, series, parallel, src, dest } = require('gulp') const sourcemaps = require('gulp-sourcemaps') const plumber = require('gulp-plumber') const eslint = require('gulp-eslint') const uglify = require('gulp-uglify') const browserify = require('browserify') const buffer = require('gulp-buffer') const tap = require('gulp-tap') const log = require('gulplog') function buildScripts(cb) { src('js/**/*.js') .pipe(plumber()) .pipe(eslint()) .pipe(eslint.format()) .pipe(tap(function (file) { log.info('bundling ' + file.path); // replace file contents with browserify's bundle stream file.contents = browserify(file.path, { debug: true }) .transform('babelify', { presets: ['@babel/preset-env'] }) .bundle() })) // transform streaming contents into buffer contents (because gulp-sourcemaps does not support streaming contents) .pipe(buffer()) .pipe(sourcemaps.init()) .pipe(uglify()) .pipe(sourcemaps.write('.')) .pipe(dest('dist')) cb() } If I import from 'gsap/dist/ScrollTrigger', then the build no longer fails. But then I am unable to register the plugin in browser and get this message: Uncaught TypeError: n.gsap.registerPlugin(...) is not a function at Object.1.gsap The transpiled line that throws an error looks like so: _gsap.gsap.registerPlugin(_ScrollTrigger.ScrollTrigger)(function () { Any idea what is going on? Thanks!
