How about support singleton config? React must be a singleton dependency, it'a a necessary config.

I presume this is related to the max limit of open files by my OS (catalina 10.15.4). Looking for alternatives to changing this value, leaving that as a last resort.

For a specific repo with a lot of files, I've opted for the AutomaticVendorFederation. The build is now at + 28339 hidden modules. When webpack-dev-server launches, everything compiles successfully. After a few seconds my console is flooded with

Watchpack Error (watcher): Error: EMFILE: too many open files, watch

While ctrl+c will not kill the node process, I have to pkill node.

Am I meant to not watch these files or increase the limit?

Consider below condition

1. App1 project use package A, A depend on package B, but package B is not in App1 project package.json dependencies attribute.
2. App2 project use package B in code and package.json dependencies have package B.

Result

package B is not shared, how to solved this condition

Other condition

without use AutomaticVendorFederation plugin, manual config shared package also have this case

There is no guard on this line:

exclude.some(...)
