Accessing a public method in a listener's class

Hi, I currently have a public method on my listener that i want to access from another listener, below is an example of my current code:

...
export class UserEvent extends Listener {
    private interval: NodeJS.Timeout | null = null;

    public override run() {
        if (!config.enabled) return;
        this.startInterval();
    }

    public async resetInterval() {
        if (this.interval) {
            clearInterval(this.interval);
            this.startInterval();
        }
    }

    private startInterval() {
        this.interval = setInterval(async () => {
            this.assignMember();
        }, 1000 * 60 * 60);
    }
...

...
export class UserEvent extends Listener {
    private interval: NodeJS.Timeout | null = null;

    public override run() {
        if (!config.enabled) return;
        this.startInterval();
    }

    public async resetInterval() {
        if (this.interval) {
            clearInterval(this.interval);
            this.startInterval();
        }
    }

    private startInterval() {
        this.interval = setInterval(async () => {
            this.assignMember();
        }, 1000 * 60 * 60);
    }
...

my goal here is to call

 resetInterval()

 resetInterval()

from another listener, but i currently have no idea how to call it without calling

new

new

on the listener above.

Solution

Seeing you use TypeScript, you can do this instead:

import type { UserEvent as TimerUserEvent } from './event-name.js';

export class UserEvent extends Listener {
  ...

  public myMethod() {
    const timer = this.store.get('event-name') as TimerUserEvent;
    timer.resetInterval();
  }
}

import type { UserEvent as TimerUserEvent } from './event-name.js';

export class UserEvent extends Listener {
  ...

  public myMethod() {
    const timer = this.store.get('event-name') as TimerUserEvent;
    timer.resetInterval();
  }
}

That being said, pieces are supposed to be independent, so I would recommend you have a shared file for the two listeners and call from there rather than having a listener call another listener, it'll also solve casting and naming issues.
