Retrieving class properties in typescript

I am working with a class that has numerous methods, which I refer to as myClass. When calling it, the syntax is as follows:

myClass[key]()

Is there a way to retrieve the valid values for key? I tried using keyof myClass, but received an error message stating 'myClass refers to a value, but is being used as a type here'

The issue may stem from the fact that myClass is currently defined in a .js file and encapsulated like this:

const myClass = new MyActualClass();
export default myClass

Is there a method to extract this information without converting the .js file to TypeScript and accessing the details directly from MyActualClass?

Answer №1

If you're looking to access the dynamic property names, one way is by utilizing either Object.keys or Object.getOwnPropertyNames.

In TypeScript, suppose you want to define a variable that can store the keys for an object of your class, the syntax would be as follows:

let key: keyof typeof myClass;
