MPC RSS

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

Documentation

• Automatic Feed Updates -- Scheduler and CLI setup
• Grouping Modes -- Category, source, date, or timeline
• Custom Templates -- Override templates and available variables
• Routing -- SEO-friendly URLs
