Discover the steps to extend static generic methods in Typescript

My issue lies in compiling Typescript code as the compiler doesn't seem to recognize the inheritance between my classes.

Whenever I attempt to compile, an error arises:

Property 'create' does not exist on type 'new () => T'.

export abstract class Resource {

    // creates a new resource and returns it
    static async create<T>(this: { new(): T }, resource: T): Promise<T> {
      const resource = ... // using "this"
      return resource;
    }

}

export abstract class ContainerResource extends Resource {

  static async addToContainer<T>(this: { new(): T }, resource: T, containerId: string): Promise<T> {
    r = await this.create(resource); // Property 'create' does not exist on type 'new () => T'.

    // do some stuff

    return r;
  }

}

I anticipate this code to successfully compile. However, even with

addToContainer<T extends Resource>
, it still doesn't work :(

Answer №1

Referring to a static method using "this" is incorrect. It is better to substitute "this" with "Resource"
