# News Feed

The newsfeed module is one of the default modules of the MagicMirror. This module displays news headlines based on an RSS feed. Scrolling through news headlines happens time-based (updateInterval), but can also be controlled by sending news feed specific notifications to the module.

    config: {
      // The config property is optional.
      // If no config is set, an example calendar is shown.
      // See 'Configuration options' for more information.

# Notifications

# Interacting with the module

MagicMirror's notification mechanism allows to send notifications to the newsfeed module. The following notifications are supported:

Notification Identifier	Description
`ARTICLE_NEXT`	Shows the next news title (hiding the summary or previously fully displayed article)
`ARTICLE_PREVIOUS`	Shows the previous news title (hiding the summary or previously fully displayed article)
`ARTICLE_MORE_DETAILS`	When received the first time, shows the corresponding description of the currently displayed news title. The module expects that the module's configuration option `showDescription` is set to `false` (default value). When received a second consecutive time, shows the full news article in an IFRAME. This requires that the news page can be embedded in an IFRAME, e.g. doesn't have the HTTP response header X-Frame-Options set to e.g. `DENY`. When received the next consecutive times, reloads the page and scrolls down by `scrollLength` pixels to paginate through the article.
`ARTICLE_LESS_DETAILS`	Hides the summary or full news article and only displays the news title of the currently viewed news item.
`ARTICLE_TOGGLE_FULL`	Toggles article in fullscreen.
`ARTICLE_INFO_REQUEST`	Causes `newsfeed` to respond with the notification `ARTICLE_INFO_RESPONSE`, the payload of which provides the `title`, `source`, `date`, `desc` and `url` of the current news title.

# Notifications sent by the module

MagicMirror's notification mechanism can also be used to send notifications from the current module to all other modules. The following notifications are broadcasted from this module:

Notification Identifier	Description
`NEWS_FEED`	Broadcast the current list of news items.
`NEWS_FEED_UPDATE`	Broadcasts the list of updates news items.

Note the payload of the sent notification event is ignored.

# Example

The following example shows how the next news article title can be displayed on the MagicMirror.

this.sendNotification("ARTICLE_NEXT");

# `newsfeed` specific notification emitting modules

The third party MMM-Gestures module supports above notifications when moving your hand up, down, left or right in front of a gesture sensor attached to the MagicMirror. See module's readme for more details.
