JSONFeed

JSONFeed is a library for creating and parsing JSONFeed feeds.

Parsing a JSON Feed string:

String jsonFeedString = "{ ... }";

// Parse the JSON feed string
Feed feed = DefaultFeed.fromString(jsonFeedString);

// Get some fields from the feed
Version version = feed.getVersion();
String title = feed.getTitle();
String description = feed.getDescription();
URL homePageUrl = feed.getHomePageUrl();
URL feedUrl = feed.getFeedUrl();

// Get the item list from the feed
List<Item> itemList = feed.getItemList()

Creating a new JSON Feed:

// Create a new item
Item item = new DefaultItem("1")
        .setTitle("First Item")
        .setSummary("First item summary.")
        .setUrl(new URL("https://somehost.com/article/1"));

// Create an item list and add the item
List<Item> itemList = new ArrayList<Item>();
itemList.add(item);

// Create a new feed
Feed feed = new DefaultFeed()
        .setTitle("Feed Title")
        .setDescription("Feed Description")
        .setHomePageUrl(new URL("https://somehost.com/"))
        .setFeedUrl(new URL("https://somehost.com/feed.json"));

// Add the item list to the feed
feed.setItemList(itemList);

// Get the feed as a JSON feed string
String jsonFeedString = feed.toJSONString()

Support:

This library supports both JSONFeed 1.0 and 1.1, and there is support for 'upgrading' a feed from version 1.0 to 1.1. Additionally the parser will inspect the feed and upgrade it if needed.

Dependencies:

This depends on JSON-java for JSON parsing and creation.
