For example, I have a class Module and many classes will inherit from it. For example, the User module or the Session module, and I want to store all these classes in one place.

class User extends Module { } api.addModule(User)

How do I describe the type of argument taken by the addModule function?

 addModule (moduleClass:Function){ this.modules[moduleClass.name] = moduleClass }

moduleClass: Function ??? Fankshen works, but I do not need any functions, namely classes, and even inherited from Module

moreover I want to create the addModules function

 api.addModules([User, Session])

so that you can take an array of classes =) tell me how to describe such a parameter in the typescript? so that no matter how instanced a class is, namely the class itself or its classes are heirs.

    To indicate that we need not an instance of the class, but the class itself, the following construction is used: typeof Class

     addModule(ModuleClass:typeof Module) { this.modules[module.name] = ModuleClass } getModule(name:string):typeof Module { return this.modules[name] } addModules(modules:typeof Module[]) { }

    My mistake was that I used an outdated typeof (Module) type syntax that I used to talk about the developers of the typing script that they had in 2012 ^ _ ^
