I’ve extracted this question from this thread I’ve been working on an oEmbed endpoint for consider.it that returns HTML that can be Oneboxed in a Discourse thread. Currently, the oEmbed html snippet is mostly just an iframe, along with a small javascript library injected into the containing window.…

From the posts I’ve followed it seemed like using an Iframe would be the way to go? Could you please elaborate? I really hope this feature can be integrated, since it would help our forum a lot

Great info, thanks @sam Two responses: I think the short video I recorded above demonstrates a situation where my non-whitelisted javascript is executed against Discourse’s policy. So it might be a bug. If you think it is worthwhile, I’d be happy to file a report. Is it possible for me to cre…

Reviving an old thread: I’d like the same functionality, dynamically resized iframes. Since it seems allowing oembed providers to include script tags isn’t likely to happen (which I completely understand), a reasonable alternative would be for Discourse to implement a pretty simple hook.
