The lib folder contains server-side business logic, Custom API controllers and FHIR API Gateway. The js folder contains all client-side business logic, modules and components.

The platform folder contains the client business logic, application components and UI elements. The main folder contains the main application module that combines all other components to create the client application.

The plugins folder contains many packages that can be registered in Kailona's config file, main/src/config/default.js to expand the features and functionality of Kailona such as new data types.
