A Composer plugin that merges multiple composer.json files at runtime to simplify dependency management for modular applications.
What is Composer-Merge-Plugin?
Wikimedia Composer Merge Plugin is a Composer plugin that allows a project's main composer.json file to include and merge configuration from additional composer.json files. It enables modular dependency management by dynamically combining dependencies, autoload rules, repositories, and other settings from specified files, simplifying complex setups where core requirements coexist with optional components.
PHP developers and maintainers of large applications or frameworks, such as MediaWiki, that need to manage dependencies across multiple modules, extensions, or sub-projects via Composer.
Developers choose this plugin over manual dependency management because it provides a hierarchical, automated way to merge configurations, supports flexible conflict resolution strategies, and ensures critical files are validated, reducing configuration overhead in modular projects.
