    -w /app/client \
    node:16.14.2-slim \
    sh -c 'npm install -g grpc-tools && \
        grpc_tools_node_protoc --js_out=import_style=commonjs,binary:. --grpc_out=grpc_js:. -I /app/ /app/helloworld.proto && \
        npm install'

docker run --net=host --rm -v $PWD:/app -w /app/client node:16.14.2-slim node client.js

Or from client/ folder (cd client/), you can run node client.js.
