How do I dispose a custom module?

[jankapunkt]

I have a custom module that registers a global event listener on window to recompute on resize:

import { debounce } from '../utils/dom/debounce.js'
import Quill from 'quill';
const Module = Quill.import('core/module');

export class LineNumber extends Module {
  constructor(quill, options) {
    super(quill, options);
    this.quill = quill;
    this.options = options;
    this.container = document.querySelector(options.container);
    quill.on('text-change', this.update.bind(this));
    window.addEventListener('resize', debounce(this.update.bind(this), 100));
    this.update(); // Account for initial contents
  }

  update() {
     // compute line numbers
  }

  dispose () {
    // remove event listener here
  }
}

I found no clue in the docs on how to cleanup when my components unmount, possibly causing a memleak when switching between pages a lot.

Anyone got an idea here?

Okay I found the solution using getModule, which I call before my components unmount:

const lineNumber = quillInstance.getModule('lineNumber')
lineNumber.dispose()
