Build NodeJS back-end with dependencies for NWJS desktop application

I have an application that is built with angular (FE), and Nestjs (BE). The application is working fine on the server.

I am trying to combine the application with NWJS environment in order to create a desktop application.

I can run the application coping FE build code and BE build code + node_modules to a folder in the NWJS environment.

Now I need to build the BE including dependencies (NestJS, xml2json etc) to a single server.js file so that I do not need to copy the node_modules folder to NWJS environment to work the application.

I tried to build with Webpack but the tool says

the request of a dependency is an expression', 'Module not found:

Error: Can't resolve 'pino-pretty' in ...

when running the Webpack command.

Is there any way to configure Webpack to build a single server.js file for NodeJS back-end application alone with its dependencies

or

any other build tool that can be suggested to achieve this task with an example would be highly appreciated.

NWJS

NestJS

Thank you
