TYPO3 Headless - Content via REST API using t3api

This repository is a proof of concept of outputting TYPO3 content (pages and content elements) via REST API using t3api extension.

Tested on TYPO3 v9.5 and v10.4

Features of t3apicontent extension

  • Registers GET collection and GET item endpoints for pages. It supports page tree, which is limited to 3 levels. Maximum depth can be adjusted in annotation of \Klamparski\T3apicontent\Domain\Model\Page::pages property (parameter of \SourceBroker\T3api\Annotation\Serializer\MaxDepth annotation).

  • Outputs content elements added to the page inside \Klamparski\T3apicontent\Domain\Model\Page::contentElements property.

  • Uses JMS serializer and TYPO3 discrimination feature to keep separate PHP classes for every type of content element (based on CType column). Downside of such solution is that for every type of content element we need configure few places: TYPO3 TCA ($GLOBALS['TCA']['tt_content']['types']), Extbase (TypoScript inside config.tx_extbase.persistence.classes; see EXT:t3apicontent/ext_typoscript_setup.txt), JMS (see EXT:t3apicontent/Resources/Private/Serializer/Klamparski.T3apicontent/Domain.Model.AbstractContentElement.yml). From the other side there are big advantages: output only properties which are really used by content element, customize serialization groups and types for specific content elements (for one element bodytext should be parsed as RTE and for another it can be plain HTML or text).

  • Outputs header_link field of content element as parsed TypoLinks using built-in t3api serialize handler.

  • Outputs bodytext of textpic content element as RTE field parsed via TYPO3 build-in parser. It Registers custom serializer handler (\Klamparski\T3apicontent\Serializer\RteHandler) utilizing t3api serializer handlers registration (in final solution this should be included in t3api core)

  • Process images inside textpic content element: Inside \Klamparski\T3apicontent\Domain\Model\TextpicContentElement::images images with default sizes are outputted while inside \Klamparski\T3apicontent\Domain\Model\TextpicContentElement::getImagesMin() rules for maxWidth and maxHeight are applied. VirtualProperty annotation ensures that imagesMin property is included in JSON output.
