Is it possible to programmatically catch all events on the page in the browser?

A bit late to the party but I did create something that might be useful for others here.

This is an ES6 Class that captures all events from an element that is known to that element. This demo allows you to change the element time in the page, as well as read out the events with clickable links to their MDN page as well as interact with the element and see how the events are triggered with time stamps.

I hope this helps

Class code

class EventSystem {
  constructor(element) {
    this._ = {
      element: null
    }

    return this;
  }

  getAllEventTypes({blacklist = [], whitelist = []} = {}) {
    const events = [];
    for (let property in this._.element) {
      const match = property.match(/^on(.*)/);
      if (match) {
        if ((whitelist.length > 0 ? whitelist.indexOf(match) !== -1 : true) &&
            (blacklist.length > 0 ? blacklist.indexOf(match) === -1 : true)) {
          events.push(match[1]);
        }          
      }
    }
    return events;
  }

  getElementType() {
    return this._.element.tagName.toLowerCase();
  }

  setElement(element) {
    this._.element = element;
    return this;
  }

  applyEvents(events, callback) {
    events.forEach((event) => {
      this._.element.addEventListener(event, (ev) => {
        if (typeof callback === 'function') {
          callback(event, ev);
        }
      })
    })
  }
}
