Base variants

In site handling, "base variants" represent different bases for a website depending on a specified condition. For example, a "live" base URL might be https://example.org/, but on a local machine it is https://example.localhost/ as a domain - that is when variants are used.

Base variants exist for languages, too. Currently, these can only be defined through the respective *.yaml file, there is no backend user interface available yet.

Variants consist of two parts:

  • a base to use for this variant
  • a condition that decides when this variant shall be active

Conditions are based on Symfony expression language and allow flexible conditions, for example:

applicationContext == "Development"

would define a base variant to use in "Development" context.

A configured base variant for development context.

The following variables and functions are available in addition to the default Symfony functionality:

Example

config/sites/<some_site>/config.yaml | typo3conf/sites/<some_site>/config.yaml
rootPageId: 1
base: 'https://example.org/'
baseVariants:
  - base: 'https://example.localhost/'
    condition: 'applicationContext == "Development"'
  - base: 'https://staging.example.org/'
    condition: 'applicationContext == "Production/Sydney"'
  - base: 'https://testing.example.org/'
