Thanks for the contribution! This will totally be a useful addition. Left a few comments.
Also, does this work with nested validation? https://github.com/typestack/class-validator#validating-nested-objects. I have a feeling it might not because of the target metadata filtering in https://github.com/epiphone/class-validator-jsonschema/pull/48/files#diff-a2a171449d862fe29692ce031981047d7ab755ae7f84c707aef80701b3ea0c80R79.

Is it possible to use namespaces in this file to import two classes with the same name? Might be clearer than declaring one here and another in a separate file.
I mean something like
namespace Foo { export class User { } } namespace Bar { export class User { } }| const targetMetadatas = _(metadatas) | ||
| .filter(metadata => { | ||
| return metadata.target === target | ||
| }).value(); |

Let's use the native Array.filter here instead of lodash

| export type ClassType<T> = new (...args: any[]) => T; |

We can omit the unused generic here and below I think.
| export class User { | ||
| @MinLength(5) | ||
| @IsString() | ||
| name: string; | ||
| } |

Can we also test that if the two User classes both have a property with the same name but different class-validator decorators, only the desired decorators get applied in the resulting schema?

Hello.
First of all, thank you for amazing package! It is very useful, but in my case I needed ability to extract JSON Schema for a specific class (with duplicate names).
The problem with
validationMetadatasToSchemasis that it merges schemas with the same names.So if I have 1 User class with
nameproperty and another withfirstName, JSON Schema will include both (obviously I could use unique names, but for current project I cannot avoid duplicates).As a workaround I created a separate function which solves the issue for me and might be useful for someone else as well.
