Access to static properties via this.constructor in typescript

Question

I want to write es6 class:

class SomeClass {     static prop = 123      method() {     } } 

How to get access to static prop from method() without use SomeClass explicitly? In es6 it can be done with this.constructor, but in typescript this.constructor.prop causes error "TS2339: Property 'prop' does not exist on type 'Function'".

Answer 1

but in typescript this.constructor.prop causes error "TS2339: Property 'prop' does not exist on type 'Function'".

Typescript does not infer the type of constructor to be anything beyond Function (after all ... the constructor might be a sub class).

So use an assertion:

class SomeClass {     static prop = 123;     method() {         (this.constructor as typeof SomeClass).prop;     } }

Microsoft programmer talking this but there is not a good way to type constructor. You can use this tip first.

class SomeClass {     /**      * @see https://github.com/Microsoft/TypeScript/issues/3841#issuecomment-337560146      */     ['constructor']: typeof SomeClass      static prop = 123      method() {         this.constructor.prop // number     } }
