You should not use ng serve --prod in actual production!

But for checking locally, you can add a production environment to the project config in angular.json.

"production": {
   "buildTarget": "api:build"
}

If you are running in production you may want to seek out ways to properly run a node process in production such as PM2.

thanks @FrozenPandaz got it working with following config.
yes, my intention is to test app with environment.prod.ts config.

        "serve": {
          "builder": "@nrwl/builders:node-execute",
          "options": {
            "buildTarget": "api:build"
          },
          "configurations": {
            "production": {
              "buildTarget": "api:build:production"
            }
          }
        },
