rss(feed, [options])

Converts a tree of posts in JSON Feed format to RSS format. The feed can be any map-like object.

This transformation is performed by the small json-feed-to-rss library. JavaScript programmers can use that library to apply the transformation in regular JavaScript projects.

Include the core post data in the feed argument. Use the options argument to specify additional options beyond what’s supported in JSON Feed:

• feed_url: the public URL where the RSS feed lives
• language: a language tag identifying the language of the feed content
