How to make a volume in a docker container to reflect laravel changes in real-time

I'm currently working on a docker dev env running ember on the frontend and laravel on the backend. I have the code volumed in, but any changes made to the code are not reflected until I rebuild the container using "docker-compose up --build."

I've tried pointing the volume to a few different paths and haven't been able to get the code to update in real time. Is there a widely accepted path in a laravel application to point the volume to in order to reflect changes in real-time?

volume strings I've tried for the container in docker-compose.yml: ./backend/src/storage/app:/app

./backend/src/storage:/app

./backend/src/app:/app

Clearing caches hasn't reflected changes, a docker-compose up without the --build flag hasn't worked either.
