Is your feature request related to a problem? Please describe it

Currently to use this package in a common library, we have to use resolver overrides which can be brittle and tedious to maintain.

Describe the solution you'd like

Use conditional exports to export the main entry (probably under "node" or "require") point as well as the shim under "browser" or "default" (and maybe "react-native" too?).
