<p>This is a Gutenberg block that pulls posts from an RSS feed.</p>
<p>The plugin uses the <code>fetch_feed</code> WordPress function to display the entries from a feed on your website (https://codex.wordpress.org/Function_Reference/fetch_feed).</p>
<h3>Requirements</h3>
<p>Gutenberg has to be installed on your WordPress instance in order to use this plugin.</p>
<h3>Configuration</h3>
<p>Once the plugin is installed, you’ll first need to enter the URL of your feed URL. There is a helpful button for validating the feed URL. If there is something wrong, an error will appear.</p>
<p>Here are the available feed options:<br />
 1. Number of posts to be shown on the front-end. The default number is 10.<br />
 2. Whether to show the descriptions of the posts on the front-end.<br />
 3. Whether to show the dates of the posts on the front-end.<br />
 4. Whether to show the content of the posts on the front-end.</p>
<h3>WordPress Hooks</h3>
<p>There are a few WordPress hooks that allows you to modify the output. All of them are related to the front-end.</p>
<p><strong>Actions</strong></p>
<pre><code>grf_before_items -- called before displaying the feed on your site.

grf_before_item -- called before each feed entry.

grf_after_item -- called after each feed entry.

grf_after_items -- called after all listed entries.
</code></pre>
<p><strong>Filters</strong></p>
<pre><code>grf_frontend_output -- allows you to modify the HTML markup that will be displayed on the site.<h3>Front-end error messages</h3>
</code></pre>
<p>In case, a feed isn’t configured or it isn’t a valid one, the following messages might appear on the page that uses the custom block:<br />
 – Missing feed URL: <code>Please set the URL of the RSS feed through the WordPress dashboard.</code><br />
 – Incorrect feed: <code>Please make sure the provided URL is a valid feed.</code><br />
 – No posts: <code>No feed items found.</code></p>
