TYPO3 provides an "Application Information" dropdown to show some information.
This dropdown can be extended with custom information, e.g. some API endpoints or currently deployed Git Commit Hash. This can ease debugging as you can easily check whether the system runs the newest version with all changes applied.
I did that for one of our customers and wanted to share how easy it is to add such information.
Functional tests won't mock single implementations. But code often interacts with external systems by sending requests, e.g. via Guzzle. Guzzle is the default library used within TYPO3, so you might need to mock the requests within functional tests.
This blog post explains our solution which is based on Guzzle Docs and Susis Blog post on how to mock Guzzle Client implementation within Unit Tests.
TypoScript by concept is meant for frontend context only. There is TSconfig for backend as well. Extbase introduced a way to also configure backend modules via TypoScript. Nowadays TypoScript is also used in other context, e.g. scheduler tasks or commands.
I'll explain how the actual TypoScript is loaded, so you understand that part and can use it.
Since TYPO3 10.0 it is possible, actually necessary, to use FQCN (=Fully Qualified Class Names) for controllers when configuring plugins and modules. This provides a new benefit in terms of reusing and sharing code between different extensions.
This blog post will explain the benefit and provide an outlook in a possible future of TYPO3 Extbase extensions.
I prerecorded a talk for the t3oce 2020. The talk should introduce beginners into the concepts of TYPO3. It should explain how to add and edit content, as well as what content in Context of TYPO3 actually is. Once one knows these basic concepts, I explain how to render content with TYPO3.
The talk should work as an basic introduction into TYPO3 for integrators as well as developers.
TYPO3 provides a comprehensive caching implementation. Built into all parts of TYPO3. By default TYPO3 tries hard to provide a working caching solution for Websites. This way all generated content is cached whenever possible and delivered right from cache without rendering. This leads to some issues if dynamic content is added. Some bypass this issue by deactivating caching partly or for whole pages.
This post explains how to configure TYPO3 to make caching work without deactivating it. One place where caching does not work out of the box is changing files via Filelist module, changes there will not be reflected in content elements using a file reference. This example is used to explain how caching works in TYPO3 and how to adjust caching.
From time to time you need to test some email within your TYPO3 installation. Whether it might be that you are a developer sending some mail via a CommandController or Plugin, or you are an integrator configuring EXT:powermail or EXT:form to deliver some mail.
In all cases you need to make sure this mail is not send to external addresses like your customer during development and testing. Also you need to be able to check the content of the mail. In this blog post you will learn what mbox is and how to use it.
