Can't access Dockerized Vue's localhost:8080 on host machine (despite EXPOSE-ing port)

Question

I can't access my Vue app on localhost:8080 anymore after Dockerizing the app.

I have a Dockerfile with the following contents:

 # Base the image off of the NodeJS image
 FROM node

 # Set the working directory to be the HOME directory
 WORKDIR /root

 # Install NPM dependencies early in the build process
 COPY ./package.json /root
 COPY ./package-lock.json /root
 RUN npm install

 # Specify what port will be available - necessary for VPC network
 EXPOSE 8080

 # Copy our application files to the image
 COPY ./.browserslistrc /root
 COPY ./.eslintrc.js /root
 COPY ./.env /root
 COPY ./babel.config.js /root
 COPY ./README.md /root
 COPY ./vue.config.js /root
 COPY ./public /root/public
 COPY ./src /root/src

 # Start the container running our Node app
 CMD ["npm", "run", "serve"]

(Before Dockerizing, npm run serve allowed me to access the Vue app through my web browser.)

Then I run the PS command docker build:

PS C:\Users\User\mealSocial-dev> docker build -t finalvue app

It seems you are running Vue CLI inside a container.    
Access the dev server via http://localhost:<your container's external mapped port>/    
Note that the development build is not optimized.   
To create a production build, run npm run build.

Despite it saying It seems you are running Vue CLI inside a container. Access the dev server via http://localhost:<your container's external mapped port>/, I get This page isn’t working. localhost didn’t send any data. ERR_EMPTY_RESPONSE:

I'm EXPOSE-ing the port in the Dockerfile and adding the -p 8080:8080 tag when I run docker run. What am I missing?

from the comment section:

add --host 0.0.0.0 to npm run serve

or

add host: 0.0.0.0 to a config (./vue.config.js)
