graphql-upload-minimal VS class-transformer

Using the latest version of graphql-upload with NestJS can be quite tricky since it uses mjs, this means we need to use dynamic imports, alternative you can use graphql-upload-minimal, or graphql-upload version 13.

JSON serialization is 200x faster than class-transformer

Also OP can check out class-transformer + class-validator if he want to properly instantiate objects and validate them with precise and verbose output of potential format errors. OP can even go the god tier way by setting up a custom RxJS operator that does that for him easily.

Start by installing the class-transformer and class-validator packages for dto validation (see more in the docs), sharp for image optimization, and the S3 client packages.

To implement new features, the original class-transformer had to be abandoned, since it does not publish the meta date that it collects. Fork that publishes metadata to the global - https://github.com/petrzjunior/class-transformer (PR: https://github.com/typestack/class-transformer/pull/929)

I really enjoyed using class-transformer and class-validator for this.

The class-validator / class-transform looks really nice for formatting/validation but there is also joi. suretype is attractive since theoretically typeconv could generate jsonSchema for json-schema-faker and Open API docs.
