Generating file in different project and branch with Mix

I have this structure in my develop enviroment:

• Code/my-project-laravel-api (which is the one I deploy to production)
• Code/my-spa-vue-project (which is pointing to localhost:8000 js when i am in local)

Every time I want to push to production I have to move the compiled js to the laravel-api project and then push it.

I wanted to know if there is a way to configure webpack to save that file in the other project when i run npm run production

At the same time I have two production branches for the same project with slightly differences in api and js code.

Im a bit lost figuring out how automate this process.

Thnak you!
