Node in one conteiner with composer?

Hi, I have a question. I’m developing an application where Laravel will serve as an API and I’m trying to create a Dockerfile. I’m considering using Soketi, which is installed via NPM. However, I’m not sure how to implement Soketi. In my Docker Compose setup, I have a service for Soketi, but the Laravel container does not have NPM, so I can’t install it there. Should I install Soketi only in the frontend container where I’ll have Nuxt.js? My goal is to avoid adding Node.js to the Docker image for Laravel, which will only serve as an API.

this is my dockerfile
