I made an Angular build of my app using:

$ ng build

and uploaded the result onto my remote server:

I also have installed on the server an appropriate node version and Angular CLI. When I try to run the app $ ng serve I see:

Error: This command is not available when running the Angular CLI outside a workspace.

My purpose is to run frontend and backend using Nginx as a proxy server. Maybe I shouldn’t use Angular CLI? I also have SSR in my app. I just wanted to leave all the internal Node.js kitchen (including the SSR magic) to Node.js and just add a Nginx reverse proxy.
Please, help me to figure out.

Here is my angular.json build section:
