Issue

"mongoose": "^7.1.1"

Currently, these arguments' types are all any, see:

mongoose/types/index.d.ts:

  export interface ToObjectOptions {  
    /** if set, mongoose will call this function to allow you to transform the returned object */
    transform?: boolean | ((doc: any, ret: any, options: any) => any);
  }

I use HydratedDocument<Something> to specify the type for the doc argument, but I am not sure it's correct.

import mongoose, { HydratedDocument } from 'mongoose';

interface Something {
  name: string;
}
const somethingSchema = new mongoose.Schema<Something>({
  name: String
}, {
  collection: 'something',
  toJSON: {
    transform(doc: HydratedDocument<Something>) {

    },
  }
}

Any suggestion?

HydratedDocument<Something> is correct in that case. We'll update the types.
