Guidelines for structuring Android and Kotlin Multiplatform apps using Clean Architecture—module layout, dependency rules, UseCases, repositories, Room/SQLDelight/Ktor data stacks, and DI via Koin or Hilt.

Comprehensive guide for designing robust backend APIs within the Webiny framework. It details best practices for structuring features, distinguishing between Services (multi-method, singleton) and UseCases (single-method orchestrators, transient), managing dependencies via the DI container, and implementing advanced patterns like ServiceProviders for asynchronous bootstrapping. Essential for all backend API development.

This pattern provides a comprehensive guide to implementing domain event handlers (before/after hooks) within the Webiny framework. It emphasizes the 'thin orchestrator' principle, requiring handlers to delegate all business logic to reusable service abstractions or UseCases for maximum reusability. Furthermore, it details the process of defining, publishing, and reacting to custom domain events, ensuring a clean, decoupled architecture.

This guide details the UseCase pattern, an architectural pattern used to encapsulate specific business operations within the Webiny framework. Learn how to define UseCases as injectable dependencies, manage input and output using the structured Result<T, E> type, and implement robust, domain-specific error handling. Mastering this pattern is crucial for building highly modular, testable, and maintainable backend APIs.
