    Can you try to copy package.json first and install all packages before copy all files from current directory, like this

    Dockerfile

    FROM node:12.7-alpine AS builder
WORKDIR /csswebdockerimage
COPY package.json ./
RUN npm cache clean --force
RUN npm i
COPY . .
RUN node_modules/.bin/ng build --prod --aot --build-optimizer --vendor-chunk=true


FROM nginx:1.19.0-alpine
VOLUME /var/cache/nginx
COPY --from=builder /csswebdockerimage/dist/cssweb-demo1/ /usr/share/nginx/html
COPY ./.config/.nginx/nginx.conf /etc/nginx/conf.d/default.conf
EXPOSE 80

    Don’t know if this resolves the issue, but here is how I dockerize Angular

    FROM node:12-alpine
LABEL Author="okira-e"

COPY package*.json ./
RUN npm install -g @angular/cli
RUN npm install

RUN mkdir src
WORKDIR /src

COPY . .

EXPOSE 4200
