Note that we're using the anonymous volume ('/app/node_modules') so the node_modules directory would not be overwritten by the mounting of the host directory at runtime. Actually, this would happen:
build - The node_modules directory is created in the image.
run - The current directory is mounted into the container, overwriting the node_modules that were installed during the build.DO
