it may be caused by document

[wpcfan]

I experienced this as well, it seems adding hostlistener may lead to this error too

[wpcfan]

please have a look at the https://github.com/wpcfan/universal-starter.git, I did not add any document/window stuff, just a directive with @HostListener, and it will cause the error

Thanks for reporting this, looks like a bug to me, will investigate.
@wpcfan if you remove the :Event then you error goes away

me help global['Event'] = null; in server.ts

[josephjohansson]

Got the exact same error and after applying the fix from @Gorniv I get the same error just with FocusEvent and KeyboardEvent. I don't know what could cause this.

Removing the type fixes this

I met the same error when run node dist/server.js. I tried with domino by adding these lines in server.ts

const domino = require('domino');
const fs = require('fs');
const path = require('path');
const Zone = require('zone.js');
const DIST_FOLDER = path.join(process.cwd(), 'dist');
const template = fs.readFileSync(path.join(DIST_FOLDER, 'browser', 'index.html')).toString();
const win = domino.createWindow(template);
const files = fs.readdirSync(`${process.cwd()}/dist/server`);
import fetch from 'node-fetch';

win.fetch = fetch;
global['window'] = win;
global['DOMTokenList'] = win.DOMTokenList;
global['Node'] = win.Node;
global['Text'] = win.Text;
global['HTMLElement'] = win.HTMLElement;
global['navigator'] = win.navigator;
global['Event'] = win.Event;
global['Event']['prototype'] = win.Event.prototype;
Object.defineProperty(win.document.body.style, 'transform', {
    value: () => {
        return {
            enumerable: true,
            configurable: true
        };
    },
});
global['document'] = win.document;
global['CSS'] = null;

So the error disappeared, and I saw another one:
ERROR TypeError: Cannot assign to read only property 'stopImmediatePropagation' of object '[object Object]'

Use global['Event'] = null; just lead me to an other error:

ERROR { Error: Uncaught (in promise): Error: no Promise impl found
Error: no Promise impl found

Any solution for this case now?

I am experiencing this bug as well, but I use aspnetcore-engine.

I created a PR to fix some issues about Event is not defined in here, angular/angular#22905.
@thovo, could you post a reproduce repo about this error

ERROR { Error: Uncaught (in promise): Error: no Promise impl found
Error: no Promise impl found

[thovo]

I am sorry that I can not reproduce for you a repository with that errors. But, to resolve my problem, I isolated the part which had the call with Event by wrapping everything in the condition of platformBrowser and it worked normally now. I hope it could help other with similar issues. Actually, I wrapped almost everything inside of platformBrowser to prevent error like above.
