TypoScript Coding Guidelines

Directory and File Names

  • As of TYPO3 8.7, the file ending can and should be .typoscript.

  • TypoScript files are located in the directory <extension>/Configuration/TypoScript.

  • File name for constants in static templates: constants.typoscript.

  • File name for TypoScript in static templates: setup.typoscript.

More information about the file ending:

  • TypoScript files used to have the ending .txt.

  • Since TYPO3 7, it is also possible to use the ending .ts. This is not recommended because it is also used by TypeScript.

  • Therefore, you should use .typoscript if you are using TYPO3 8.7 and later.
