Mark as required

[rightisleft]

It would be great if we could have a decorator that allowed use to mark a paramater as required during serialize/deserialize/auto

This would allow us to ensure that the contract is properly met.

How would imagine this plays out?

class Thing {
   @autoseralizeAs(String, true) thing1 : string;
   //or
   @autoserializeRequired thing2 : string;

}

or something else? I like the idea, I'm unsure off the top of my head what the interface for that would look like

I prefer

@autoseralizeAs(String, true) thing1 : string;

Like java style

@autoseralizeAs(columnDefinition="string", required=true)

or even just a seperate annotation

@required
@autoserialize

or require all and then opt out

@requireAll
export class Foo {

@autoserialize thing1
@autoserialize thing2
@autoserialize thing3
@autoserialize thing4

@optional
@autoserialize thing5
}

Because interfaces are compile time only in typescript - i see a lot of 'loose' declarations where data could or could not be missing depending on the source.

Having auto runtime checking of all properties would be a huge win

Yeah I agree. I think I prefer the separate annotation. I'll see what I can do about that, or feel free to submit a PR since it will take me a few days before I have time to look at this seriously

Happy to test it when its ready! I definitely dont have the bandwidth

Any news on the proposal?
This would allow me to drop all my PropTypes (React) that I'm still keeping for the runtime checks

No no update yet, haven't had the time unfortunately. feel free to submit a PR though
