Why is the loader searched from npm and not local via link?

Answer 1

https://docs.npmjs.com/cli/v7/commands/npm-link#sy...
Example at the very beginning.
The bottom line is that npm link needs to be used 2 times, first in the folder of the linked package without parameters, then in the folder where we link with the name of the linked package from its package.json
But in general this is a debugging tool, and for your purposes it is better to just give webpack absolute the path to the file with the loader, which is easiest to get through require.resolve
