composer.json

The key to developing any Magento component is its composer.json, which specifies version and dependency information for a component, among other things. You can look at examples in the Magento codebase, such as:

• Metapackage (old metapackage for Community Edition from packages.magento.com)
• Customer module
• Luma theme
• en_us language package
