Twitter widget memory leak [timeline specially]

[rulrok]

Hi.

I’m developing a SPA and Twitter’s widget.js javascript is causing a memory leak.

When only adding widget.js and removing it completly, it seems to be fine.
Once I use twttr.widgets.createTimeline(), then the problem comes up.

Here is a fiddle where I was even trying to manually ensuring that all attached events were removed.

When asking to create the timeline, a request is made to:

https://platform.twitter.com/js/timeline.b0a587d0d4f12c2689ad7e638140e2c7.js

I am suspecting that this leaving some event behind. I see there are pairs of eventListeners add and remove for click, but only one addEventListener for ‘load’ (I guess it is an iframe element).

I was trying to whack all and everything I could, but some references are kept in memory coming from ‘widget.js’.

I don’t know how widget.js and timeline.js interact.

Twitter js plugin is simply unreasonable for SPAs.
