This API provides a comprehensive set of architectural abstractions (Use Cases, Repositories, Event Handlers) for managing folder structures and permissions within a web application. It implements the Command Query Separation (CQS) and Domain-Driven Design (DDD) patterns, ensuring clean separation of concerns for CRUD operations, lifecycle events, and complex business logic related to folders and folder-level permissions (FLP).

This comprehensive guide outlines best practices for designing and organizing robust backend APIs within the Webiny framework. It details core architectural patterns, including singleton Services (for external APIs or cohesive domain logic), transient UseCases (single-method business orchestrators), and Repository patterns for persistence. Use this skill to structure features, manage dependencies, and ensure scalable, maintainable backend code.

This guide details the implementation of the EventHandler pattern for robust, event-driven architecture. Learn how to create handlers that react to the system's domain events (lifecycle hooks), process payloads, and publish custom domain events. Crucially, it enforces architectural best practices by ensuring handlers act as thin orchestrators, delegating all core business logic to separate, reusable service abstractions.

This guide details the architectural shifts when migrating existing Webiny v5 plugins to the v6 feature-based Dependency Injection (DI) model. It covers key patterns, such as converting ContextPlugins to DI Services, adapting event subscriptions to EventHandler features, and restructuring plugin arrays into feature registrations.

This API module provides eleven core abstractions for managing email functionality. It includes interfaces for repositories (e.g., GetSettingsRepository, SaveSettingsRepository), use cases (e.g., SendMailUseCase), and event handlers (e.g., MailAfterSendEventHandler). It follows clean architectural patterns to ensure the separation of concerns and provides a robust, scalable foundation for all mailing-related features.

This guide outlines architectural patterns and best practices for building scalable, production-ready APIs with FastAPI. It covers proper project structure, separating concerns using routers, services, and CRUD layers, implementing dependency injection for database sessions and authentication, defining Pydantic schemas for request/response, handling asynchronous operations, and managing custom error responses.

This guide details the architectural and implementation patterns for building modular applications or microservices using the tinystruct Java framework. It covers core concepts like using the @Action annotation for dual routing (CLI/HTTP), managing request state with Context, and using native Builder for JSON serialization, ensuring a lightweight and structured development environment.

This guide provides comprehensive, structured error handling patterns for modern applications using TypeScript, Python, and general architectural principles. It covers essential concepts like typed custom errors, Result patterns, API error transformers, and React Error Boundaries. Learn how to implement fail-fast mechanisms, differentiate user-facing messages from developer logs, and ensure system resilience against unexpected failures.

Aria functions as a System Architect, responsible for establishing the definitive structural foundation of the entire system. She designs comprehensive blueprints covering the data model (schema, relationships, constraints), API contract specifications (endpoints, auth, pagination), modular file structure, and selection of core architectural design patterns. Her output ensures that no code is written without a rigorously defined, approved architectural plan, minimizing ambiguity and technical debt.

A comprehensive reference guide covering advanced architectural design patterns crucial for modern, scalable distributed systems. Topics include CQRS, Event Sourcing, Saga, and Circuit Breaker, providing best practices for microservices migration and fault tolerance.

A comprehensive guide detailing the selection criteria for core modern system components, including databases (SQL/NoSQL), caching, message queues, and API protocols. It helps architects choose the optimal technology for specific use cases, scalability needs, and architectural patterns.

This skill generates a comprehensive and structured developer onboarding document for any service or codebase. It guides new engineers through the entire product lifecycle, covering architectural overview, local development setup, key coding patterns, testing strategies, CI/CD deployment processes, and team contacts, ensuring rapid productivity from day one.
