Optional flag which changes string to date in case of format data-time or date

In the project I am working on, we use openapi v3. The schema contains objects which use the type string with the format date-time.

example:

ExampleType:
  title: ExampleType
  type: object
  properties:
    id:
      type: integer
    validFrom:
      type: string
      format: date-time
      example: "2012-10-27T17:18:30.966Z"

We did not want to convert the date everytime and therefore we created a middleware for the server and client-side that automatically converts it from string to Date. When creating the models via the openapi-typescript-gencode tool, the output models use the type string (as intended). But in our case we need it to be of type Date, which is a special case. Therefore an optional flag to enable this feature would be great.

What is needed?

It needs to remember the format value and in case of date or date-time the output type should be Date instead of string.

About implementing it

I would try to implement it and in case that anyone wants to help me, that would be great.

@ferdikoomen here a the list for the frontends:

Angular

uses JSON.stringify() (source)

axios

uses JSON.stringify() (source)

fetch

has no automatic parsing (source)
