Interesting, is Jest still having issues with ES modules?

Yes! If we ditch that, a bunch of unit tests where this module is directly or transitively used will fail.

Hey @tyxla , I think this should probably have been a major release since it causes build breakage downstream unless configuration changes are made to support transforming is-plain-obj |
|
@rjchow, it definitely created more friction than we anticipated. Apparently, the Node ecosystem is far from ready to start using ES Modules today. I would rather avoid calling it a breaking change since it doesn't have any impact on the functionality of the updated packages. Is it only Jest that has issues with this package? We should fix it with the revised patch that @tyxla opened yesterday. If this impacts more tools, then maybe we should switch to another library that still supports CommonJS like |

What?
This PR removes the
_.isPlainObject()usage completely and deprecates the function.Alternative to #42471.
Part of #16938.
Why?
Lodash is known to unnecessarily inflate the bundle size of packages, and in most cases, it can be replaced with native language functionality. See these for more information and rationale:
@wordpress/api-fetchpackage haslodashas a dependency #39495How?
We're using the is-plain-obj package because it does exactly what we want, has type bindings, and is simple and well-contained enough.
