High CPU Usage in Docker when running Nuxt in dev

When I run nuxt with yarn run dev in my docker container, the CPU usage of the container is high. Also, every few seconds, the logs output this:

frontend-container    | [nitro-runtime] request: 0.04ms
frontend-container    | [nitro-runtime] render:html: 0.058ms
frontend-container    | [nitro-runtime] render:response: 0.009ms
frontend-container    | [nitro-runtime] beforeResponse: 0.006ms
frontend-container    | [nitro-runtime] dev:ssr-logs: 0.007ms
frontend-container    | [nitro-runtime] afterResponse: 0.306ms
frontend-container    | [nitro-runtime] request: 0.039ms

frontend-container    | [nitro-runtime] request: 0.04ms
frontend-container    | [nitro-runtime] render:html: 0.058ms
frontend-container    | [nitro-runtime] render:response: 0.009ms
frontend-container    | [nitro-runtime] beforeResponse: 0.006ms
frontend-container    | [nitro-runtime] dev:ssr-logs: 0.007ms
frontend-container    | [nitro-runtime] afterResponse: 0.306ms
frontend-container    | [nitro-runtime] request: 0.039ms

I don't know if that is expected behavior, but when I run yarn run dev outside of the container, the CPU usage is a lot lower and the nitro-runtime logs don't occur. Here's my Dockerfile:

# frontend/frontend.Dockerfile
FROM node:20.10.0-alpine AS dev
ENV HOST 0.0.0.0
WORKDIR /code/frontend
RUN apk --no-cache add curl
COPY package.json ./
RUN yarn cache clean && yarn install
COPY . .

# frontend/frontend.Dockerfile
FROM node:20.10.0-alpine AS dev
ENV HOST 0.0.0.0
WORKDIR /code/frontend
RUN apk --no-cache add curl
COPY package.json ./
RUN yarn cache clean && yarn install
COPY . .

and my compose file for the frontend container:

    frontend:
        env_file:
            - ./.env
        environment:
            - BASE_URL=${BASE_URL}
        working_dir: /code/frontend
        container_name: ${FRONTEND_CONTAINER_NAME:-frontend}
        build:
            context: ./frontend
            dockerfile: ./frontend.Dockerfile
            target: ${STAGE:-dev}
        ports:
            - ${FRONTEND_9000_PORT:-9000}:9000
            - ${FRONTEND_8080_PORT:-8080}:8080
            - 3000:3000
        volumes:
            - ./frontend:/code/frontend:rw
            - frontend_node_modules:/code/frontend/node_modules
        tmpfs: /tmp
        command: /bin/sh -c "cd /code/frontend && yarn run dev --host"

    frontend:
        env_file:
            - ./.env
        environment:
            - BASE_URL=${BASE_URL}
        working_dir: /code/frontend
        container_name: ${FRONTEND_CONTAINER_NAME:-frontend}
        build:
            context: ./frontend
            dockerfile: ./frontend.Dockerfile
            target: ${STAGE:-dev}
        ports:
            - ${FRONTEND_9000_PORT:-9000}:9000
            - ${FRONTEND_8080_PORT:-8080}:8080
            - 3000:3000
        volumes:
            - ./frontend:/code/frontend:rw
            - frontend_node_modules:/code/frontend/node_modules
        tmpfs: /tmp
        command: /bin/sh -c "cd /code/frontend && yarn run dev --host"
