why you copied # copy configs to /app folder if you not npm install after? Usually we copy configs and then run npm install and then we copy code. In that order we can use docker cached layer for npm install command. In dockerfile above you will npm install every time when your code changed..

@Edr2 you're right... it should rather be

COPY package*.json .
npm install
