Current behavior

All swagger schemas are empty and contain no information at all.

Expected behavior

Documentation detailing the property types on schemas should be inferred from the typescript definitions as described here and here. Like so:

Minimal reproduction of the problem with instructions

Reproduction: https://github.com/robertmain/meal-plan/tree/update-swagger

Instructions:

1. Download the app from the link above (the branch is important!) 1 Install the dependencies and navigate to localhost:3000/api (yeah, I know it’s a crappy URL scheme…I’m working on it)

What is the motivation / use case for changing the behavior?

Empty API documentation isn’t very useful…? 🤔

@robertmain Did you solved after build through webpack?

My project already using nest build but I have same issue as you

Entire project has latest nest modules but it dosen’t work… My global version of nest/cli and typescript are same as follows’ devDependencies

Here’s my package.json I’m sorry about not being able to provide reproduction repo, it’s a company project.

Same for me. Newest Nest Version using newest cli with nest new, added the plugin to nest-cli.json and it produces empty models. I’m using docker, but I’m also copying the nest-cli.json into that container

UPDATE:

Please bury me alive, I did’nt use .dto.ts files (yet) but .type.ts files. I had to adjust the “dtoFileNameSuffix” therefore. Now it’s working for me!

I’m encountering the same issue. If I don’t add @ApiProperty() the prop will not show up in the schema.

Using version 4.1.2

I’ve downgraded back to 4.0.9, which seems to work as described in the docs for now.
