How to build for both Node.js and Browsers?

Question

Hi! I've just come across rollup-plugin-ts, and I'm liking what I'm seeing, I do have a question though, which is, how does this play with compiling a single package for both Node.js and Browsers? I currently use the rollup-plugin-typescript2 plugin, which seems to not care, but from what I can tell rollup-plugin-ts, due to supporting browserslist would maybe compile code that would work in browsers but not in node?

Would I need two different plugins? One for Node.js and one for Browsers?

Or would we just set browserslist to something like:

  "browserslist": [
     "last 2 versions",
     "maintained node versions"
   ]

And that would output code that's compatible with both Node.js and browsers?
