Preview Plugin

julian

On the way in, you'd be hooking into filter:post.create, possibly. At that point content from an RSS feed would be html.

I'll tell you how I'd approach it, which may be the wrong approach

npm i cheerio
Parse incoming html and find all the anchors
Do your preview generation
Replace content using cheerio selectors.

Funny enough, this is exactly how link-preview works

Yes, OGProxy works the same way My thoughts would be around a regex - something like nodebb-plugin-beep but with the ability to completely remove words rather than just say "[censored]" - I could fork that plugin and write in that functionality actually...

Hmmm....

@phenomlab I'm sure you've seen this?

RegEx match open tags except XHTML self-contained tags

I need to match all of these opening tags: <p> <a href="foo"> But not self-closing tags: <br /> <hr class="foo" /> I came up with this and wanted to make

Won't stop people like us from trying though hahaha

@julian Yes, thanks. Actually, I think I narrowed down the issue. There is a fork of nodebb-plugin-rss that I am using called nodebb-plugin-rss-brad - I think the changes here are that it renders other HTML (description - like v1.3 of the official NodeBB version did), so I went for that.

I think it is that plugin that adds "Via: " as it is doing it on all links, and not on my other site which uses the stock NodeBB version.

Let me confirm, and if so, this can be closed.

my site use this plugin ,no image,why?

@huige There are some sites that use hotlinking protection to prevent the images being returned - not much we can do to fix that either. Does this happen on all preview renders, or a select few?

@huige Are you using any browser add-ins that may disable features?

huige

@huige Are you using CloudFlare?

huige

@phenomlab
I didn't use cloudflare, and I tested it again, and the link on my site can be parsed normally in the post, is it a cross-domain problem?

phenomlab

@huige Do you have any headers set which restrict the ability for sites to display the images?
