Current behavior

I am building a nestjs application using webpack, but it build, the schemas of DTO´s breaks.

Application in dev

Application build (schemas breaks)

Minimum reproduction code

https://github.com/rudemex/nestjs-starter.git

Steps to reproduce

1. git clone https://github.com/rudemex/nestjs-starter.git
2. npm install
3. npm run build
4. run compiled application
5. can see the demo of project here: https://rudemex-nestjs-starter.herokuapp.com/docs/

Expected behavior

Schemas names should be as I define in code.

This is expected because you are minimizing the code. By doing so, webpack changes the names of the classes, and the metadata read at runtime reflects those names. If you don't really need minimization (there isn't much need for it on the server side) then I'd suggest not using it

Hi @jmcdo29 Is there any configuration for webpack that transpiles the code in a single file? similar to monorepo but for applications.

[jmcdo29]

Just using nest build --webpack should do that automatically.

@jmcdo29 Great, and does it detect if the transpiling is for production? or do you have to expand the configuration?
