Hm, after some investigation, it seems that there is no good solution. The current state (1.7.0) is the way momentjs authors recommend. However, it is broken for Rollup users (or any ES6-module users in general). Is there any reason the import was changed back in the 1.7 version? I can't find it from the git changes, it is just part of a big commit.

@sebek64 I asked guys to add snowlake to ngx-bootstrap
so I could test build on rollup\gulp\system.js on each build
