Constructor

The Constructor<T> type represents a class constructor signature.

export type Constructor<T = any> = new (...args: any[]) => T;

Use this type when APIs need a runtime constructor function for creating or deserializing typed instances.

import { Constructor } from '@cratis/fundamentals';
function createInstance<T>(ctor: Constructor<T>): T {
return new ctor();
}
class Customer {
name = 'Ada';
}
const customer = createInstance(Customer);

In Fundamentals, Constructor<T> is commonly used by decorators and serialization helpers to keep runtime type information.
