Apps: Filter RSS feeds

[ErisDS]

In the discussion issue for the Filters API it was mentioned that it should be possible to filter RSS feeds.

The suggestion is that there should be a filter called rss.feed which filters the whole feed, and one called rss.item for each item. I’m not 100% certain that we need both, I believe that rss.feed would have access to all the data so could be used to do both, but I’m willing to be shown I’m wrong on this.

Anyhow, it would be great to get the rss filter into place so that it can be used in anger to create real world apps.

"used in anger" +1 :D

Would the feed be the processed / rendered XML, or the big object that /core/server/controllers/frontend.js uses shortly before sending it out?

Personally having both would be fab. rss.item would be used to simply add data to each and every item of the feed (such as flotsam iTunes needs for a podcast), while rss.item could be used to add jetsam to the channel info.

There are a few things we need to address here:

rss.item will always get passed a single post - so that one can fetch additional meta data (app_fields) for the post. rss.feed will allow you to change the head of the feed.

One thing to note: We currently use node-rss which is a very very limited package that doesn't allow you to add custom fields (like iTunes media fields) - dylang/node-rss#5

I have searched quite a bit for alternatives but to no avail. The best way to go at this is to build a new package that will allow a lot more flexibility. (I'm about to do that).

👍 This would also allow to append a link to the original page inside the feed items. Useful if your site gets scraped by other parties and you want to make clear that the content is coming from your own site.

FYI: I started an App that can serve as example for the filters: https://github.com/halfdan/Ghostcast

👍 Are you working on adding in these filters?

[halfdan]

Yea will do that.

Temporarily closing all of the app specific issues (tagged with later). Will review & reopen those that are still relevant when we kick off that project, which should be shortly after Zelda lands.
