Answer 1

Per this related answer you can mount your main directory but ignore the node_modules using a second anonymous volume in the docker-compose.yml. This allows you to mirror your directory but the container should keep its own node_modules.

volumes:
  - .:/var/www/${APP_NAME}_web
  - /var/www/${APP_NAME}_web/node_modules/
