## gorilla/feeds
[![GoDoc](https://godoc.org/github.com/gorilla/feeds?status.svg)](https://godoc.org/github.com/gorilla/feeds)
[![Build Status](https://travis-ci.org/gorilla/feeds.svg?branch=master)](https://travis-ci.org/gorilla/feeds)
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
### Usage
```go
package main
import (
"fmt"
"log"
"time"
"github.com/gorilla/feeds"
)
func main() {
now := time.Now()
feed := &feeds.Feed{

/*
Syndication (feed) generator library for golang.
Installing
go get github.com/gorilla/feeds
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:
import (
"time"
. "github.com/gorilla/feeds"
)
now = time.Now()
feed := &Feed{
Title: "jmoiron.net blog",
Link: &Link{Href: "http://jmoiron.net/blog"},
Description: "discussion about tech, footie, photos",
Author: &Author{Name: "Jason Moiron", Email: "jmoiron@jmoiron.net"},
Created: now,
Copyright: "This work is copyright © Benjamin Button",
}
feed.Items = []*Item{
&Item{
Title: "Limiting Concurrency in Go",
Link: &Link{Href: "http://jmoiron.net/blog/limiting-concurrency-in-go/"},
Description: "A discussion on controlled parallelism in golang",
Author: &Author{Name: "Jason Moiron", Email: "jmoiron@jmoiron.net"},
Created: now,
},
&Item{
Title: "Logic-less Template Redux",
Link: &Link{Href: "http://jmoiron.net/blog/logicless-template-redux/"},
Description: "More thoughts on logicless templates",
Created: now,
},
&Item{
Title: "Idiomatic Code Reuse in Go",
Link: &Link{Href: "http://jmoiron.net/blog/idiomatic-code-reuse-in-go/"},
Description: "How to use interfaces <em>effectively</em>",
Created: now,
},
}
From here, you can output Atom, RSS, or JSON Feed versions of this feed easily
atom, err := feed.ToAtom()
rss, err := feed.ToRss()
json, err := feed.ToJSON()
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
atomFeed.Subtitle = "plays the blues"
atom, err := ToXML(atomFeed)
rssFeed.Generator = "gorilla/feeds v1.0 (github.com/gorilla/feeds)"
rss, err := ToXML(rssFeed)
jsonFeed.NextUrl = "https://www.example.com/feed.json?page=2"
json, err := jsonFeed.ToJSON()
