Expected Behavior

I build a production build of my node app, which is generated from @nrwl/node, calling nx build api --prod. I copy the generated files onto my server (or just another directory) and start it with node main.js.

Current Behavior

The error I get when starting is:

> node main.js
internal/modules/cjs/loader.js:800
    throw err;
    ^

Error: Cannot find module 'tslib'

}

[vincaslt]

I sense this is because api build does not include vendors. Is there a configuration option I'm missing?

[vincaslt]

I added this flag in production build config: "externalDependencies": "none"
