Scrollmagic requires some customisation to your webpack.config.js
file in order to work correctly.
Specifically, you should add the following to your resolve
section:
resolve: {
modules:[
// ...
],
alias: {
"TweenLite": path.resolve('node_modules', 'gsap/src/uncompressed/TweenLite.js'),
"TweenMax": path.resolve('node_modules', 'gsap/src/uncompressed/TweenMax.js'),
"TimelineLite": path.resolve('node_modules', 'gsap/src/uncompressed/TimelineLite.js'),
"TimelineMax": path.resolve('node_modules', 'gsap/src/uncompressed/TimelineMax.js'),
"ScrollMagic": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/ScrollMagic.js'),
"animation.gsap": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/plugins/animation.gsap.js'),
"debug.addIndicators": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/plugins/debug.addIndicators.js'),
},
},
Merge this along the other settings you’ll find there and you should be good to go!
P.s: also make sure you have const path = require('path');
at the top of your file!
