importing scrollzzz from 'scrollzzz' results in empty object returned

importing 'scrollzzz/dist/scrollzzz.esm' works

I confirm the bug, it happens also when using Parcel bundler.

It's strange anyway, because I export three different bundles: iife for browser (linked to pkg.browser), cjs for nodejs (linked to pkg.main), es6 the new import standard for modules (linked to pkg.module); it should be the bundler job to choose the correct build based on its configuration, I don't understand why this is not working.

Scrollama export only one bundle (umd) which works on both client and server side, which make things simpler. I'll add an umd version and point it to pkg.browser fields, this should fix the issue.

Hi, thanks for the report! Are you using webpack? If so, this seems related to #5756

[bovas85]

Not sure :) most other libs I use including scrollama work as intended when using import

I think it's due to the fact your main points to the browser iife rather than pointing to the main one
An example in scrollama:

based on this

you'd need to export the UMD as main in package.json
