We have built a project with a deep tree of dependencies with npm install and have a lot of issues under Microsoft Windows (secondary target).
I have read about pnpm and it seems to be a solution for us.
How to migrate our nested repository?
Build a new one from scratch, using pnpm?
Finally, I have made a backup of node_modules and rebuilt it from scratch with pnpm and added concat to have only one JavaScript source and applied Google-compiler to it.
The only difficulty was about bootstrap because it have changed a lot in two years. We need to keep the old look of it, so the command I used is pnpm install bootstrap@3.3.7.
After completion, the look and feel was identical but node_modules has grew from 8 MB to 12 MB...
