Building Packages

Building Packages

Concrete CMS packages are modular components that extend the functionality of the platform. This skill is essential for developers who want to create custom functionality or integrate third-party services into their Concrete CMS projects.

Basic Workflow for Package Development

Follow these steps to develop a custom package in Concrete CMS:

1. Initialize the Package Directory:

Create a new directory under packages/ with a lowercase, underscore-separated name (e.g., packages/my_custom_package).

1. Create the Package Controller:

Create a controller.php file in the package root. Define the package handle, version, and basic information.

1. Implement Installation Logic:

In the install() method of your controller, add code to register block types, themes, single pages, or other entities.

• [Installing Entities Reference](references/install_entities.md)

1. Add Custom Functionality:

• Extend Core Classes: [Extending Core Classes Reference](references/extending_core.md)
• Custom Block Types: Use the building-blocktypes skill.
• Single Pages: Use the building-singlepages skill.
• Routes and Services: [Routing and Service Providers Reference](references/routing_services.md)

1. Install the Package:

Use the Concrete CMS Dashboard or CLI (concrete/bin/concrete c5:package:install my_custom_package) to install your package.

1. Update and Refine:

When making changes to the package structure (like adding a new block type), update the $pkgVersion in controller.php, implement the upgrade() method, and run the update from the Dashboard or CLI (concrete/bin/concrete c5:package:update my_custom_package).
