Nest.js bundle size too large by default

Upon running nest build command, I was expecting that the build would pick up only the imported modules from node_module folder.

However, the command did not pick up the releavent files and minifined them. Instead it picked up the node_modules directly from the root folder.

As a result, the final build size of the application is extreamely large.

I need help to reduce the build size.
