Typescript x Signals

[Delmotte-Vincent]

Hi, I was searching for using signals with Typescript but I don't find any information about that. Is it something that is plan to do or signal will never support typescript ?

They already support TypeScript out of the box. Is there something that you feel is missing from the experience?

[Delmotte-Vincent]

Is there documentation about that ?

I don't understand the question. It works exactly the same way in JavaScript vs TypeScript. The only difference is that you can pass some generics in case the type cannot be auto inferred.

interface MyComplexType {
  foo: number;
  bar: string | null;
}

const sig = signal<MyComplexType | null>(null)

// same thing for the hook variant
const sig = useSignal<MyComplexType | null>(null)

That would conclude the whole documentation for TypeScript. I wouldn't know what else to mention in a TypeScript specific documentation. That's really all there is to it.
