javascript - How to implement cross-project page display in React

Question

I am doing outsourcing, it is a react project. Another part of the project is being done by other companies. Now Party A needs the entire two projects into one project. In order to maintain the confidentiality of the source code, I refuse.
Then the question is, how to merge two react react-router projects into one project when the two codes are independent?
Option one, set a jump in my project, click to jump to another project;
Option two, copy his code to my side, and then transform it;
Option three, two We develop two projects together, and others can see my code.
Obviously, the third option is to shoot directly, confidentiality; the second option, the amount of modification is too large; the first option, the jump is very weird;

Are there any other good solutions? No iframe

Answer 2

The key question is whether you have the same page with both what you do and what they do, so that you can determine the appropriate solution
