How to copy package.json files for each side separately in Webpack?

Question

webpack

There are several modules with a very long dependency chain (which the system complains about because the files are longer than 259). Winchester is also not very good because he has to run through a thousand small files 30 times a day (I don’t have an SSD). It was decided to compile these modules (each into a separate file) to speed up the assembly and simplify the copying of modules for projects.
There are almost no problems with assembling modules, but it is necessary for correct operation that the package.json file is copied to each module.
