feeds is a web feed generator library for generating RSS, Atom and JSON feeds from Go |
||||||
|
applications. |
||||||
|
|
||||||
|
### Goals |
||||||
|
|
||||||
|
* Provide a simple interface to create both Atom & RSS 2.0 feeds |
||||||
|
* Full support for [Atom][atom], [RSS 2.0][rss], and [JSON Feed Version 1][jsonfeed] spec elements |
||||||
|
* Ability to modify particulars for each spec |
||||||
|
|
||||||
|
[atom]: https://tools.ietf.org/html/rfc4287 |
||||||
|
[rss]: http://www.rssboard.org/rss-specification |
||||||
|
[jsonfeed]: https://jsonfeed.org/version/1 |
||||||
|
|
||||||

Feeds provides a simple, generic Feed interface with a generic Item object as well as RSS, Atom and JSON Feed specific RssFeed, AtomFeed and JSONFeed objects which allow access to all of each spec's defined elements. |
||||||
|
|
||||||
|
Examples |
||||||
|
|
||||||
|
Create a Feed and some Items in that feed using the generic interfaces: |

You can also get access to the underlying objects that feeds uses to export its XML |
||||||
|
|

atomFeed := (&Atom{Feed: feed}).AtomFeed() |

rssFeed := (&Rss{Feed: feed}).RssFeed() |
||||||
|
jsonFeed := (&JSON{Feed: feed}).JSONFeed() |
||||||
|
|
||||||
|
From here, you can modify or add each syndication's specific fields before outputting |
||||||
|
