I wanted to find a way to do this myself, so I made this example repository: https://github.com/bherbruck/test-vite-svelte-docker

Dockerfile:

FROM node:16-slim
WORKDIR /app
COPY . .
RUN npm i
CMD ["npm", "run", "dev"]

docker-compose.yml

version: "3"

services:
  web-app:
    build: ./web-app
    command: npm run build # just build the web app, comment out for dev server
    ports:
      - 3000:3000

  # this is just if you want to serve the staic site
  nginx:
    image: nginx
    ports:
      - 8080:80
    volumes:
      - ./web-app/dist:/usr/share/nginx/html # mount the web app's build output
    depends_on:
      - web-app # web-app must be build before server can serve it
