Is it possible for Typescript to support type or interface "destructuring" (if that's the right term)?
I am attempting to achieve something similar to the code snippet below:
type SomeRandomType = {
propertyOne: string;
propertyTwo: number;
...
};
type SomeRandomORType = "propertyOne" | "propertyTwo" | ...;
Can we create SomeRandomORType without manually typing properties from SomeRandomType? Something like this:
type SomeRandomORType = Destruct<SomeRandomType>;
If you want to access the names of each property in an interface or object with a type that could be a string or number, you can use the keyof operator. This seems like it could be what you are searching for.
interface myInterface {
property1: string;
property2: string;
property3: number;
}
type keysOfMyInterface = keyof myInterface;
// This assignment is valid as "property1" exists in the interface.
const variable1: keysOfMyInterface = "property1";
// This assignment is invalid as "property4" does not exist in the interface.
const variable2: keysOfMyInterface = "property4";
