How to set docker-compose for VUEJS to auto-restart when changing files?

Question

Docker

Set up docker-compose.yml. The database is launched on postgres and an external folder with saving data from the database
Backend on python on the FastAPI framework. Runs and works as it should. Auto-restart when changing local (not in the container) files.

Problem setting up Vue js. Everything starts, but when changing files in the folder mounted to the container, the changes are not reflected in the running one.
What am I doing wrong?
How to make the container with VUE react to changes in local files?

Dockerfile for pprint_vue

FROM node:15.10.0
ARG APP_DIR=vue_crm
WORKDIR /${APP_DIR}
COPY package*.json ./
RUN npm install --no-optional
EXPOSE 8080
CMD ["npm", "run", "serve"]

Found a solution. 3 days spent
source
and more

environment:
      - CHOKIDAR_USEPOLLING=true

there is a file in pprint_vue folder

.dockerignore

.gitignore
.git
.idea
node_modules

As a result, it looks like this.

Dockerfile

FROM node:lts-alpine as build

ARG APP_DIR=app
WORKDIR /${APP_DIR}
ENV PATH /app/node_modules/.bin:$PATH

COPY package.json ./
RUN npm install [email protected]
RUN npm install   --no-progress --ignore-optional
RUN npm install @vue/cli -g

EXPOSE 5000

CMD ["npm", "run", "serve"]

Because changed the standard port for VUE. package.json changed a bit

package.json

"scripts": {
        "serve": "vue-cli-service serve --port 5000",
        "build": "vue-cli-service build"
    },
