How to expand the node_modules folder in docker at the build stage?

Question

Docker

In short, the task is this:
In docker, dependencies are usually installed in the node_modules folder, and this folder is inside the container.
I need this folder to be not only inside the container, but also on the host, because all the necessary things like tslint, typescript are installed in it, which are used in the PhpStorm development environment to check the code.
Just copying it after installation is stupid and ugly, because there will be just two copies of the same folders.
And now the most important question: How to do it beautifully?
