How to properly organize and use your JS developments?

Question

JavaScript

Good afternoon.
I have some developments (js, css, scss, vue, ...) that I would like to use in different projects.
And if with Java / Kotlin it is clear how to arrange it - with the Gradle project, for example, then with JS - it is not clear.
I want webpack to build normally and the development environment (Idea) to see them normally and help.
Who does what? How to be?

Answer 1

npm packages, individual repositories, git submodule.
Choose what you like.
