Seems, that ES6 code needs to be compiled into ES5 (hello, modern web...):

Some third-party packages don't compile their code to ES5 before publishing to npm. This often causes problems in the ecosystem because neither browsers (except for most modern versions) nor some tools currently support all ES6 features. We recommend to publish code on npm as ES5 at least for a few more years.

Thus, it might be the case, to use some bundler with babel. Look at Rollup:

Use webpack for apps, and Rollup for libraries
Webpack and Rollup: the same but different
