Possible use of JSON.stringify

Good evening!

I was wondering if there’s a good way of doing the serialization while making use of JSON.stringify. The decorator could implement a function toJSON which is called by JSON.stringify by definition (if the function exists).

So it would basically do the following:

toJSON(): string {
    const serializer = new TypedJSON(__CLASSNAME__);
    return serializer.stringify(this);
  }

But decorators are run at declaration time, so obtaining the instance of the class calling the stringifyfunction is not an option.

Any ideas? Extending a class doesn’t seem a good solution…

This is to support inheritance. You can use the decorator on a super class and it will still work on subclasses; take a look at the test. You sow a grain of doubt in me, but I am pretty sure minifing only changes the name, the object in the prototype stays the same.

Hey Apidcloud, I pushed 1.3.0 with @toJson. You can try it out.

Regarding the second point, I agree, such function would be helpful and would make the encapsulation better, but what about the function name? Currently there is no standard way for that, like for the stringify — JSON.parse uses a reviver which does not seem to be much better than just using TypedJSON.parse. And, also this does not give any feedback to typescript. You will get an error whenever you would want to use it. You could write a declaration for that, but it is as much work as writing the function itself. And, it seems it is not possible to do this inside a decorator for the time being: https://github.com/Microsoft/TypeScript/issues/4881
