Hangs IE11 #42

Closed steveschmitt closed 3 years ago

steveschmitt commented 5 years ago

In an Angular 6.1.9 app, we added the following to app.module.ts:

import { create as rxjsCreate } from 'rxjs-spy';
rxjsCreate(); // Start rxjs-spy

We find rxjs-spy works great in all other browsers, but in IE11, the browser hangs when attempting to load the app. The screen is blank and IE shows an error message at the bottom:

localhost is not responding due to a long-running script

If I wait for about 10 minutes, the app will finally show up. But then each navigation within the app takes 1-2 minutes to complete and even popping up a modal takes 10 seconds. These should be near-instantaneous.

If I comment out the rxjsCreate() call, the app runs normally.

Yes, I know IE11 is slow. But what is rxjs-spy doing that slows things down so drastically?

I don't know. I don't use or support IE.

However, you might find something useful/actionable in my comments in this issue: https://github.com/cartant/rxjs-spy/issues/6
