Link three webpack builds together?

Question

JavaScript

Guys, hello! If anyone has an idea how to implement such a task, I will be grateful!
What the task looks like:
1. I have three projects (three modules), each one is in its own folder.
2. I run each module on my own port.
I need to make it so that I can somehow add the other two projects to one (main module), and if I change anything in them, it will immediately be displayed in the main project. How to link them together. At the same time, all of them must also remain independent and run separately on their port and be displayed. That is, the modules are independent of each other, and the main module simply renders them and monitors the changes.
