It is recommended to use the styleguide extension to auto generate several example pages which can be used for testing the frontend and backend of TYPO3.
The typo3/cms-styleguide extension is part of the TYPO3 core repository. It used mostly to showcase TCA / FormEngine features but has since evolved to provide additional features.
The styleguide extension can create pages within the TYPO3 site, specifically:
The "Styleguide TCA demo" will create several pages showcasing TCA features, including examples for common column types.
The "Styleguide Frontend" uses a custom TypoScript template provided by the styleguide extension and creates pages which can be viewed in the frontend.
Once the styleguide extension is activated, it is possible to create (or delete) the pages via command line:
# show help bin/typo3 styleguide:generate -h # create pages bin/typo3 styleguide:generate -c # or (with DDEV) ddev exec bin/typo3 styleguide:generate -c
Activate the styleguide extension in the extension manager
Click on ? in the top bar
Click on the Styleguide menu item
The Styleguide overview appears.
Click on TCA / Records / Frontend
Click the buttons:
Create styleguide page tree with data
Create styleguide frontend
The pages will now be created. Wait a moment until a flash message appears.
