Send the `this` value when calling the constructor of the subordinate module - designated typing

Help needed for upgrading code from JavaScript to TypeScript and dealing with circular dependencies.

Directory:

Main.ts
Helper.ts

Main Module:

import Helper from "./Helper"

export default class Main {
    helper:   Helper

    constructor() {
        this.helper = new Helper(this);
    }
}

Helper (Subordinate) Module:

import Main from "./Main"

export default class Helper {
    main: Main;

    constructor(main: Main) {
        this.main = main;
    }
}

Answer №1

It seems like you are engaging in a 'circular' process. To enhance the functionality of your classes and their interactions, I suggest delving deeper into the concept. One effective approach would be to utilize class extension. For instance, consider creating subclasses based on your Main class:

Your Main class:

class Main {
  modifySomething(str) {
    console.log(str);
  }
}

Your Assistant class:

import Main from "./Main";

class Assistant extends Main {
  constructor() {
    super(); // This grants access to properties and methods from the Main class
  }

  initiateAction() {
    this.modifySomething('wow!'); // Invocation of a method from the parent class
  }
}
