Developer roadmap

This topic introduces the high-level workflow for a developer who wants to create or customize the Magento application. Developers can also package and distribute their customizations to merchants.

Key points:

• Minimum required elements:

  • Declare component dependencies in composer.json.
  • Register the component using registration.php.

  • Component-specific XML definition files:

    • Modules: module.xml
    • Themes: theme.xml
    • Language packages: language.xml

• Distribute your component:

  • Package your component in .zip format.

    Use our validation tool to check your package before you distribute it.

  • If you upload the component to Magento Marketplace, it should be less than 30MB in size.
