How to connect the work of Gulp and Composer?

Question

Composer

How can I do 2 jobs at once? It's just that I always do FrontEnd first when creating a Gulp project (using SASS, compressing images, etc.). After that, I transfer the finished template to my local OpenServer server, and create a Composer project there. But then sometimes you need to make some changes, and for this I go back to the Gulp project and then again transfer the project to Composer. All this is very inconvenient. Today I connected Gulp and Composer projects, and it seems to me that some kind of porridge has turned out ...) How to connect all this? MB is there any convenient standard? There is something similar in Laravel.
