TYPO3 Config Handling Extensions

This package extends helhum/typo3-config-handling with an extension system that allows to create flexible configuration templates that can be bundled into Composer packages and thus easily usable in multiple projects.

Installation

Simply install the desired extensions, there is normally no need to directly install this package.

Look for available extensions on Packagist.

The package helhum/typo3-config-handling is automatically required by this package and can be omitted in or removed from your project. For safety, however, it can be additionally required to prevent accidental uninstall.

Configuration

To enable support for TYPO3 Config Handling Extensions, add an import line to your to your YAML configuration:

Imports are processed in the specified order, so the position in your configuration is very important. Later imports may override the configuration provided by the extensions again, and any previous configuration will be overridden by the extensions.

Additional configuration in the project's composer.json

Additionally it is possible to change the loading order of the extensions in your root composer.json in the extra section like this:

This will make sure extension1 is loaded after extension4 and before extension2 and extension3 are loaded.

Development of Extensions

The extension development is an easy task, best start with the TYPO3 Config Handling Extension Template.

The extension's composer.json

The type of the package is the most important part and must be set to typo3-config-handling-extension. Only packages with this type will be considered for processing. Next, a class to be used must be properly defined. Without a class, the package will try to load the configuration from the config folder using GlobFileReader. The extension loading order can be changed with the before and after keys by specifying a list of package names.

Keys in detail

• class: The class to be created to return the configuration. This class must implement the Gilbertsoft\TYPO3\ConfigHandling\Extensions\ConfigProviderInterface interface. Make sure that two backslashes are used according to the JSON definition.

• force-config-dir: If a class is set, the config folder is ignored by default. In the rare case that you want to load the configuration from the provider and the config folder, set this value to true.

• before: An array of package names, this extension is loaded before these packages.

• after: An array of package names, this extension is loaded after these packages.

The configuration provider class

The provider is responsible for the return of a configuration array and is the core of an extension. Here you implement your configuration logic, which of course can also contain only a simple configuration array or is built dynamically depending on some conditions.

Some more information is included in the interface definition.

User configurable options

An options array is read from the root composer.json and passed to provider methods. This makes it possible for the user to configure the provider as needed. An option consists of a key and a value. String, integer and boolean options are supported.

The options are read during the autoload dump. After changing the root composer.json, composer dump-autoload must be executed.
