README

TYPO3 extension for displaying RSS/Atom feeds with grouping, pagination, and background updates.

Requirements

• TYPO3 13.x or 14.x
• PHP 8.2+

Installation

composer require mpc/mpc-rss

Activate in the Extension Manager, then run Maintenance > Analyze Database Structure.

Quick Start

1. Add a content element: Plugin > MPC RSS Feed
2. Click Add Feed and enter one or more RSS/Atom URLs
3. Choose a grouping mode and save

Feeds are stored as inline records directly on the content element -- no storage page needed.

Background Updates

Feeds are cached per URL. To keep them fresh without making visitors wait:

Scheduler (recommended): System > Scheduler > Add Task > "Update RSS Feeds" -- set frequency to e.g. every 30 minutes.

CLI:

vendor/bin/typo3 mpcrss:updatefeeds
vendor/bin/typo3 mpcrss:updatefeeds --clear-cache --cache-lifetime=3600

See Automatic Feed Updates for details and troubleshooting.

Architecture

Request
  └─ FeedController::listAction()
       ├─ FeedRepository → inline feed records from tt_content
       └─ FeedService::fetchGroupedByCategory()
            ├─ fetchFeedItems()       per-URL HTTP fetch + XML parse + cache
            ├─ deduplicateItems()     link-based dedup across feeds
            ├─ groupItems()           category / source / date / none
            └─ sortAndSliceGroups()   date-desc sort + maxItems limit

Key design decisions:

• Dedicated CType (mpcrss_feed) via PLUGIN_TYPE_CONTENT_ELEMENT, not list_type
• IRRE inline records -- feeds belong to the content element, not a storage page
• Isolated cache (mpc_rss) -- clearing page cache doesn't affect feed data
• External content is sanitized at the caching layer (tags, attributes, URL schemes)
• Service layer is language-neutral; the controller translates generated group labels via XLF
• warmCache() skips grouping/sorting -- efficient for CLI and Scheduler

Content Security Policy

Feed items can reference remote images (entry.image) and link out to external articles. Because feed image hosts are not known in advance, the extension ships a frontend policy (Configuration/ContentSecurityPolicies.php) that extends img-src with the https: scheme. If you prefer a tighter policy, override it in your site package to allow only the specific hosts your feeds serve images from, e.g.:

use TYPO3\CMS\Core\Security\ContentSecurityPolicy\Directive;
use TYPO3\CMS\Core\Security\ContentSecurityPolicy\Mutation;
use TYPO3\CMS\Core\Security\ContentSecurityPolicy\MutationCollection;
use TYPO3\CMS\Core\Security\ContentSecurityPolicy\MutationMode;
use TYPO3\CMS\Core\Security\ContentSecurityPolicy\Scope;
use TYPO3\CMS\Core\Security\ContentSecurityPolicy\SourceScheme;
use TYPO3\CMS\Core\Type\Map;

return Map::fromEntries([
    Scope::frontend(),
    new MutationCollection(
        // Restrict to the specific feed image hosts you use rather than a wildcard.
        new Mutation(MutationMode::Extend, Directive::ImgSrc, SourceScheme::https),
    ),
]);

The extension never emits inline scripts or styles, so no script-src / style-src relaxation is required.
