software-architecture
Quality-focused software architecture guidance based on Clean Architecture and Domain-Driven Design principles.
- Emphasizes library-first approach: search for existing npm packages, SaaS solutions, and third-party APIs before writing custom code; reserve custom code for domain-specific logic, performance-critical paths, and security-sensitive implementations
- Enforces code style rules including early returns over nested conditions, arrow functions, component decomposition at 80+ lines, and file splitting at 200+ lines
- Promotes domain-driven design with clear separation of concerns: keep business logic independent of frameworks, avoid mixing UI with business logic, and use domain-specific naming instead of generic terms like
utilsorhelpers - Identifies anti-patterns to avoid: NIH syndrome, poor architectural choices, generic naming conventions, and treating custom code as a liability requiring maintenance and testing
Software Architecture Development Skill
This skill provides guidance for quality focused software development and architecture. It is based on Clean Architecture and Domain Driven Design principles.
Code Style Rules
General Principles
- Early return pattern: Always use early returns when possible, over nested conditions for better readability
- Avoid code duplication through creation of reusable functions and modules
- Decompose long (more than 80 lines of code) components and functions into multiple smaller components and functions. If they cannot be used anywhere else, keep it in the same file. But if file longer than 200 lines of code, it should be split into multiple files.
- Use arrow functions instead of function declarations when possible
Best Practices
Library-First Approach
- ALWAYS search for existing solutions before writing custom code
- Check npm for existing libraries that solve the problem
