For the weblog I wanted to add a "Popular posts" block to show the most visited posts of the last 30 days. I didn't find an existing extension to achieve this, so I made my own: matomoapi. It uses the Open Source statistics platform Matomo, which has an API to get the data I wanted.
You can install the extension using the TYPO3 extension manager or through composer:
composer req famouswolf/matomoapi
Documentation can be found on the Github page. I will write a post with some practical examples soon.
