Is there any tree-shaking strategy?

Hi, is there any tree-shaking strategy in ncc, like what bundlers do on front-end applications? I wonder how do you deal with the dynamic "require" while compiling. Thank you.

Meet the same question. Ncc always ignore process.env.NODE_ENV == production, and build all.

Tree shaking would be fantastic.

I have noticed that if i import from a package like this: import {find as event_find} from "event";

The whole package gets bundled. All the methods that I am not using from the 'event' package are getting bundled too.
