Feature request: Support raw JSON string properties

[mattjohnsonpint]

I need to be able to serialize/deserialize a class where some field is arbitrary JSON. For example, given this class:

@json
class Foo {
  value: string;
}

If I set bar to a string having the value {"a":1,"b":false,"c":"abc"} then normally when serializing Foo I would get:

{"value":"{\"a\":1,\"b\":false,\"c\":\"abc\"}"}

... which is correct, but in some cases I need it to just pass through the raw JSON so I can make the result be:

{"value":{"a":1,"b":false,"c":"abc"}}

I propose a @rawjson decorator:

@json
class Foo {
  @rawjson
  value: string;
}

Which would signal to the serialize and deserialize functions to just pass through anything in the string rather than attempt to encode or decode it.

Thanks.

It should also work with a string | null field, which would pass through null if set to null. And it should also work in conjunction with @alias, @omitnull, @omitif, etc. existing attributes.

Assign a property the type JSON.Raw to signify a block of Raw JSON. Example:

class Foo {
  bar: JSON.Raw;
}
