GSAP is completely flexible; sprinkle it wherever you want. Zero dependencies.
Docs & Installation
Click the green "Get GSAP Now" button at greensock.com for more options and installation instructions, including CDN URLs for various plugins.
Every major ad network excludes GSAP from file size calculations and most have it on their own CDNs, so contact them for the appropriate URL(s).
See the guide to using GSAP via NPM here.
npm install gsap
The default (main) file is gsap.js which includes most of the eases as well as the core plugins like CSSPlugin, AttrPlugin, SnapPlugin, ModifiersPlugin, and all of the utility methods like interpolate(), mapRange(), etc.
// typical import;// or get other plugins:;;// or all tools are exported from the "all" file (excluding bonus plugins):;// don't forget to register pluginsgsap;
The NPM files are ES modules, but there's also a /dist/ directory with UMD files for extra compatibility.
Download Club GreenSock members-only plugins from your GreenSock.com account and then include them in your own JS payload. There's even a tarball file you can install with NPM/Yarn. Post questions in our forums and we'd be happy to help.
